Bow is up hard, stern is in the mud, too. All of the talk is about wind load on such a boxy ship but I imagine the water pressure is quite intense with the ship completely cutting off flow. This is likely going to have a bigger economic impact on Europe that COVID. Probably going to be faster to dig a new canal around the ship.

Well ... I think they are not supposed to try to go through the canal SIDEWAYS!
Especially when its 1300 feet long.

This ship is a "suezmax" ship, it's the largest size allowed by length (400m). Length is limited by the ability to make turns. Perhaps in the future they'll also limit length based on ability to completely shut down the canal.

What is the Stem, other than a typo.
A part of the bow.

Quote (Wiki)

The stem is the most forward part of a boat or ship's bow and is an extension of the keel itself. It is often found on wooden boats or ships, but not exclusively.

The bow frame forming the apex of the intersection of the forward sides of a ship. At its lower end it is rigidly connected to the keel. It and may be a heavy flat bar or of rounded plate construction.

It appears to be infront of the bow... maybe the front of the ship.

Swinny and 1503... what is the stem?

Apologies, I misread 'stem' as "stern".

The 'bow' is generally the front part of the hull; the end of the boat aimed at the direction of travel. The 'stem' is the structural member that forms the edge of the bow. On a wood planked hull, the stem is an extension of the keel which extends from the keel to the gunwale, and forms the backbone of the the forward structure of the ship, and is also the member against which the planks terminate.



In this photo the curved part in the front is the stem. On a real boat, there would be a joint between the stem and the keel somewhere near the midpoint of the transition from the vertical stem to the horizontal keel.

A steel ship with a curved bow does not, technically, have a stem, although some people will still use the term 'stem' to refer to the forward most edge of the bow.

Could part of the problem be lack of maintenance on the canal? I'd try to use hydrodemolition of the soils at the rear of the boat and try to swing the rear out first, since it was likely the last part to become grounded.

Dick, the ship got itself perpendicular to the canal. This is a ship's problem. It did so at speed (13 knots) so it's also a salvor's problem as it got pushed in to the sand with a great deal of kinetic energy. In surprised there are no breached tanks but then again nearly every story we have heard has been lie.

Nothing was unusual about the maneuvers prior to entering the canal. Ships can't just park so they run their engine for a bit and drift for a bit. It's unfortunate that they created a pattern.

Digging may be reqired but offloading the stern of the ship will be a priority so it can be pivoted to open the canal for one way traffic at a minimum.

Sunday will be the highest tide in a while so if it can't be rotated by then it will be stuck for a long time. I don't have high hopes.

Lloyd Register estimates the daily cost including daily charter rates for delayed ships at $400 million per hour. This is literally bigger than COVID.

The biggest tugboat the Suez Canal Authority have is a 160ton power vessel - not sure what the tons here really means.

The most powerful tugboat out there Far Samson at 400ton power appears to be tied up with some work in the Baltic Sea (and by its location, maybe some where close to the landing on the German side for NordStream II pipeline ??). Another 300ton tugboat Alp Striker appears to be occupied with some work off Aberdeen.

Quote (TugboatEng)

Lloyd Register estimates the daily cost including daily charter rates for delayed ships at $400 million per hour. This is literally bigger than COVID.

Hardly. IMF estimate of the impact of COVID on Europe was about $6 trillion. At the rate of $400M/hour the ship will need to be stuck for nearly 2 years to be bigger than COVID. And that is only considering the impact on Europe.

At 400 MM$ph It won't be long before someone starts thinking about nuclear options.

What’s involved in navigating big ships down those canals? How are they steered/controlled?

Under their own power, unless entering locks, where they are pulled into position by diesel traction engines. Suez is a sea level crossing, so there are no locks there. I think it is normal to have a port captain responsible for steerage through the canal, but not sure about actual Suez procedures.

Far Samson at 400ton power is probably Bollard Line Pull, as this vessel has 35900BHP available to the propellers, 400 Ton bollard line pull is possible.

It is also not much compared to the force required to move a ship the size of the Ever Given once you consider that it not only embedded itself into the sandy bank, but is likely pushed up, and resting on the sand rather than completely floating.

Coastal Emergency Risks Assessment now does tidal modeling world wide. High Tide in this location looks rather stable here for the next few days. Tidal range is increasing, so at low tide there will be thousands of additional tons resting on the grounded parts of the hull. This places a huge bending load on the hull.


Screen shot is from Suez, the model does not extend into the canal. Caution - this is probably a misuse of the tool, the salvors will be using better tools.

Both ends of the ship grounded, support midships removed (low tide) creates the worst case sag. A similar design case is maximum wave height, with the distance between crests just a bit shorter than hull length.

Removing the Ever Given by Itsmoked March 26, 2021

Consider this method:

Drop both the ship's anchors.

Onto barges.

Take the barges across the canal to the other side.

Off load the anchors onto shore.

Take them as far as possible onto shore.

Keep them angled as close to the ship's hull as possible

Excavate BIG holes.

Drop the anchors in the holes.

Fill them both in.

Drive two of the largest available bulldozers between the chains to as close as you can to the middle of the chain runs.

In a coordinated manner push both chains outward.

Taking advantage of the vector results of such a maneuver the forces applied to by the dozers are multiplied by about 100 times. A 100ton push would translate to pull on the Ever Given of 100T x 100 or 10,000T. That would be for each chain.


This gets the pull onto the Ever Given avoiding all the weak bollard limits by instead using the two points on the ship with the highest pull strength.

It pulls from the front.

It's a straightforward concept once the math is understood.

It uses already on-site equipment. (Anchors & chains)

It's frequently used when stuck off road with uncanny success. It has never failed me.

90% of the effort is shore based and not water/floating difficult.

It lends itself very well for unsticking because as the stuck item unsticks the right-angle cable pulling or pushing motion can continue to exert a continuous but rapidly lessening force (due to the vector changing) on the tension member, keeping the extrication in motion and the cable(s) from being run over.




Keith Cress
kcress - http://www.flaminsystems.com

The salvors might off load the anchors and anchor chain just due to the weight. The Bow where the anchor and chain are stored is the end that rammed the shore, and is deeply embedded in sand.

I do not think anyone has mentioned that in addition to the ship being grounded, with it partly being supported by the sand it's ends are embedded into there is a significant flow of water along the length of the canal which is pushing on the side of the ship. Possible several thousands of tons of force against the side of the hull. This force reverses with the tide cycle.
It is not clear if this helps or hurts the salvage effort.

Judging form the pictures of the grounding, and the above listed proposed fixes, it might be timely for someone to list what the magnitude of the forces involved are. I could only laugh at the size of the "giant" bulldozer pushing up against the hull of the ship, it is the equivalent of a flea pushing a 300 lb sumo wrestler off a chair.Short of unloading the ship , the only non destructive fix I can imagine is the jet washing of sand to form a new canal bank 30 ft outboard of the original bank.

With a shipping loss of $400 million USD/day, one may wonder if destructive methods are also being considered. One bombing run might take a few minutes.

I thought that was one of the reasons it got 'wedged', and that the stern pivoted and wedged the rear into the bank on the opposite side... that's why I was thining of hydrodemolition... to wash away the soil.

I thought that all boats travelling the canal had to have an Egyptian pilot; has this changed?

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

If the stern can be floated the ship can be pivoted out of the way. The bow is high and dry, it hit first and that's where most of the energy was dissipated.

Fastest option? Sacrifice the center of the container stack and use shaped charges to split the ship in two. Swing the ship open like a gate to allow one way travel, then offload containers to the banks, and then tow away the remains.

I think I'd stick with the high winds and low visibility rationale unless something concrete comes out.

I don't buy wind or visibility. When a ship turns by rudder it pivots around a point 1/3 of the ship length from the bow. Looking at the pic from above, that pivot point is right where the ship would have normally been in the channel. The ship had to have turned in to the bank, not drifted. Saying this was intentional is a bold claim.

This is a new ship. It's still on the left side of the bathtub curve. I'd be most confident guessing that it was a mechanical/electrical failure.

It appears that this incident may already be driving up the price of crude oil. On the NY Mercantile, the May 21st contract for Crude is up nearly 4% today:

No, not buying it. The bow is quite a bit narrower than the rest of the ship. It would not have contacted bow first if it were a slow drifting. Contact would occur at the red circle.



The ship also had enough momentum perpendicular to the canal to drive far up the sides of the canal. Remember, the canal bottom is trapezoidal so it had been in contact with the bottom for quite some time.

This places a huge bending load on the hull.

What are the design loads for ships like this?

Do you design for the ship being supported by its bow?

Absolutely not. Each ship has strict limits on shear and bending. To much weight in the middle or on the ends causes hogging or sagging. Balanced but concentrated weight causes shear.

Here you see an example of a ship that hogged to death.



Also, any buckling of the bottom plating caused either directly by contact during ground or excess stresses severely weaken the hull. The ship will have to be unloaded to reduce stresses before transportation on oceans.

You design a ship to be supported by water.

The design case is hogging or sagging. https://en.wikipedia.org/wiki/Hogging_and_sagging
The design case is waves positioned for highest stress in both cases. Tugboat's example the wave height likely was significantly higher then the design case for long enough for fatigue to take control of the hull. Then you have a hull in pieces.

Grounding can easily create stresses not accounted in the design case. There is some risk of wrinkling the hull. Less risk of cracking the ship in half from a single event unless their are already undetected cracks.

Note that groundings in the canal are common. A similar ship grounded just 4 months ago and it was hardly an event.

https://www.fleetmon.com/maritime-news/2020/32089/...

It's not normal for ships to end up perpendicular. I'd be curious to see what the rudder position is at this moment.

Introduction To Steel Shipbuilding by Baker, Elijah 1943 Page 229 explains that at the time the highest loads a ship incurred where when launching, first floating a ship, from an inclined shipway. No one does that with these very large ships, the launching loads would be too high.
Figure 91 , page 102 of this reference illustrates the wrinkling described by tugboat. Physics today is the same as 1943. We do not get to wave the rules due to inconvenience.

I presume that they are also pumping out the forward tanks to lighten the bow.
Steering gear failures are not unheard of.
The BBC report said that 2 pilots were on board. My guess is that one was just in transit.
Yes, it will limp out of the canal and then be off loaded, there is repair and survey work to be done before it carries cargo again. Insurance companies are so picky.

= = = = = = = = = = = = = = = = = = = =
P.E. Metallurgy, consulting work welcomed

One of the reports indicated that high capacity pumps are needed to pump out the forward void space. That implies there is a hole somewhere in the bulb bow embedded in the sand.

The Suez pilots like cruise ships, which are scarce at the moment. They come on for a free feed, so sometimes there are more than the required two. I think the main requirement for those pilots is agility for embarking and disembarking, so perhaps their seamanship is secondary.

If they are responsible for piloting, then Egypt may be on the hook for some real damages.

If the pilot is determined to be at fault. I still think this is a mechanical fault. The angle of incidence is too perpendicular unless there was a second ship involved.

Check out how an improperly executed overtaking maneuver can doom the ship being passed. Though at 13 knots it's unlikely.the Given was being overtaken.

Also, one of my coworkers.who excelled at ship handling early and is now a pilot suggested this video explaining pivot point and how ships turn. This is important to understand how the Given ended up perpendicular.

https://youtu.be/RuhETd0hTyU

I have to do some thinking on this, I'm not a ship handling expert, but.i believe the hydrodynamic forces created by a ship running close to a bank would tend to push the bow away and draw the stern in which is the opposite of what we see.

This graphic has been posted to show just how aground the ship is. The white is dredged channel, the blue is shallow water.



The pro mariners are still specultating about a loss of electrical power.

Positive news, the stern has been floated free. However, it seems the bow has been holed. More speculation is that cargo will need to be removed. Removing ballast to float the ship makes it dangerously unstable.

There is no overtaking in the Suez Canal. It was bad luck that the grounding occurred in the single channel part of the canal. Further along, there are now northbound and southbound channels, which can be pressed into double duty.

Tug, that's a great find. I was wondering if the canal wasn't even sided as the stem seemed to sit lower and I saw a photo showing one ship behind it moored up against the bank.

But if the ship is billed that's a big blow for them. Haven't seen an update on the dredging work recently.

One of the Danish guys at works brother is over there now.

Apparently it was sand storm Low Viz.and they got hit by 50 knt gusts from a base of 15-20

The two ships behind them nearly collided and only weren't grounded due to being alot smaller.

They are going to try a collosal suction dredger to dig out round the front and back and then block flow in the middle so the current eats the banks.

I know you civil engineering types intuitively understand what cut/fill means when you see the numbers. Maybe some of you have experience in doing this with dredges. The size comparisons in the link of the ship to the Eiffel Tower and Titanic work for me.

Quote:

"An unnamed Egyptian canal authority official told late on Thursday that they would need to remove between 15,000 to 20,000 cubic meters (530,000 to 706,000 cubic feet) of sand to reach a depth of 12 to 16 meters (39 to 52 feet). That depth is likely to allow the ship to float freely again, it said.

Rather than restrict the size of ships which can use the Suez, I imagine there will be planning underway to extend the two channel system throughout. The Panama Canal now has two channels, one of which can take larger ships than the 'Panamax' ones the original channel caters for.

I can't understand why ANY more ships would be piling up waiting. They already must be knowing it will take a month to get thru this mess then waiting to unload in the big rush at the other end. Pay the 7 or 8 day penalty of going around instead and still deliver faster. Odd.

If it can't keep its heading with a 50 knt cross wind, how does it go in a typhoon?

McNutt, here in SF, all tank vessels with more than a certain volume of oil are required to have tug escort. The tug centerlead aft is there to act as brakes or steer the ship in the event of failure. With that said, studies have found tugs to be largely ineffective at steering ships at speeds above 6 knots. Puget Sound has adopted a lower speed limit as a result but other ports have not.

Well if it was a gust it must have come from the right side starboard side, because when you look at the video that Alistair posted one can see that he is going a bit to the left, but then the direction goes very fast to right like he is trying to compensate and then isn't fast enough to get the right heading back.
But I do not know where this direction value comes from

Looks like the effect that the Danish brother was on about.

Just that the first yaw took it into the side.

There was other stuff about single engine and dual rudders and rudder authority with the power off.

The recovery if you get caught is apparently full power and full rudder oppersite direction or something like that. But it takes a lot of skill of the helmsman and quick reactions of the skipper to spot what's developing and the self confidence to order full ahead.

I am pretty clueless about big boats but it's been interesting reading the discussions on the handling of them. You can see why it takes years of training to qualify on them.

Ships do not change heading immediately on a change of rudder angle. Recovering from a "bank encounter" requires counterintuitive helm commands (think - backing a trailer into a narrow space). The time and travel distance for a container ship to respond to a change in rudder angle makes over steering likely.
Turning Circle Diameter Trials for a Container ship
The example in the link is about 1/2 the size of the Ever Given, so the "advance" on rudder angle command is likely twice that shown. That would put advance ~~ 1NM (1852m).

The track plot Alister posted SUEZ CANAL Container ship Ever Given blocked Suez Canal Mar 24, 2021 Clearly shows the bank effect. At 1:51 the ship gets unstuck from the right side bank effect. Steering toward the right bank might have helped early, but as the ship started to approach the left bank the ship would need to steer toward the left bank to prevent the following swing across the canal.

Here is a larger scale of the track plot on the local chart Ship track MV EVER GIVEN grounded Blocked Suez Canal, and a model simulation.

With the costs involved in delays and in moving in a large craine, coupled with the time factor to unload by crane,
I would consider toppling a couple of hundred tonnes of containers off the ship.
A tug boat hitting the end of a slack line will easily topple several containers at a time.
Use a lifting helicopter to return the pulling line for another pull.
The saving in time will more than make up for any damage to the container contents.

When I was doing my degree they had 30 full time deck officer per year going through Glasgow nautical college. And 30 marine engineering. And the course was over subscribed. About 20% drop out for both.

And even 30 years ago they had a pretty impressive bridge simulator including fire and smoke.

I believe the current one moves as well.

They have managed to get the screw turning and rudders moving and water under the bow.

They can swing it now but there is huge lump of rock which the bow is catching on.

And there is a collosal argument on going about what to do next.

One cause of action would be to blow it up.

Easy peasy!!!!! Conventional explosives might be a bit dramatic in the vicinity of a grounded ship but there is available a " smokeless powder" under different trade names . If memory serves the one I most recently used was called Dexpan. It works by physically expanding within the confines of a drilled hole , inducing quite large cracks in rock.

Some of the ideas in this thread are absurd. Blowing up the ship or dumping containers in the water would just create a bigger problem, clearing the debris.

Those trapezoidal cross sections show a different picture than Tug's plan view above, but they are taken in the part of the canal to the north where there are two separate channels, so not applicable.

I would love to provide charts but they are very expensive.

I can see unloading, and cutting the ship in two to make a 'gate' to allow traffic to flow as being a viable option... They can clean up the contained mess, later.

If there was a way to cut the ship up in place that would be faster than removing the material under the ship, the salvors would / are already be planning that as an option. Cleaning up the mess would probably need to be completed at least to the point where nothing would spread along the length of the canal, before traffic could resume, which could be very time consuming.

Pulling / skidding containers sideways requires first lifting the containers to unlatch the container dogs that tie containers in a vertical stack together.

It might be easier to pull an entire container stack over, but at 40 tons per container, you quickly start to create undesirable unbalanced loading on the ship.

Do the tracking simulations actually show the location and orientation of the cargo ship in the canal, based on 'transponder' data, or whatever it is?

GPS receivers can calculate direction of motion if the ship is moving.
Most gps receivers include a heading sensor, often a magnetic compass (as is used in most cellphones).
AIS systems use gps position, and can use external heading sensors, so they can get heading data from a gyrocompass or the ships navigation platform.
This link explains AIS with some more detail.


Automatic Identification System (AIS): Integrating and Identifying Marine Communication Channels

The US GPS system (Navstar) uses WGS84 ad the datum, as does Europe’s Galileo. I think the Russian and Chinese systems use a different datum. Basic accuracy with real time post processing using WAAS
.
A system similar to WAAS should be viable in the middle east.

Some super tankers have a fore and an aft GPS, but I think they only broadcast one position on AIS channel.

dik, the stern is free. If they cut the ship where it meets shallow water they can tow the stern away to open the canal and salvage the bow at leisure.

Experience has proven that you can cut a containerships in half and the stern will remain upright and stable.


Shaped charges have been used successfully to split ships in the past.

Red, I am not a navigator so I can't get specific. Any navigation beacon should not be movable. They would also not be on the bottom as that would make them invisible and difficult to transmit radio frequency from. The beacon may be something as small as a VHF antenna for radio direction finding so it wouldn't be visible from satellite. They could also be GPS antennas for differential GPS.

I guess that will be the next subject of discussion... determining what to do... or they may have already decided a few days back...

The canal has been blocked a few times. The longest before this by a grounding was about 3 days. But the Egypt-Israel war kept it closed for 8 years from 1967 until 1975.

https://www.businessinsider.com.au/the-suez-canal-...

I can explain this. A ship has both a heading and a course over ground. A heading is the direction it's pointed and course over ground is the direction it's moving. For the AIS, the course over ground is sourced from the GPS. Heading for a ship this size would come come from the gyro compass though smaller vessels may use a satellite compass or magnetic flux sensor. AIS will show both to help visualize the drift of the vessel. The pointy arrow is COG and the longer ship shaped one is heading.

Tug in normal circumstances they would be on the surface, but the you should se them om the photos
Not movable I am not shore about that it's a canal in the middle of an desert with sandstorm they can fill up with sand and if there isn't time to dredge it out they might need to move or adjust the buoys from time to time

Buoys are usually on mushroom anchors. They can be pulled up and replaced but the location of the buoy needs to be precise so they don't typically get moved around.

To answer the question about the location of the GPS antenna, it can be anywhere on the ship but it's position relative to centerlines is keyed in during commissioning so the AIS position shows the true center of the ship. The second GPS antenna on super large ships is used by the pilots only as a reference point during turns.

What's weird is that in the movie in Alistair's link, the degree changes back and forth quite a bit after the boat runs aground and stands still?

"According to initial reports, the steering gear should have failed. But that was later withdrawn. A machine failure can also be used as an explanation. However, there are many indications of unforeseen weather conditions."

Same story, different day. Perhaps the class does have a disfuncrional steering gear. Admitting a faulty gear would require shutting down the entire class until the condition can be repaired.

AIS displays heading so the degree will fluctuate based on position error when the ship is not moving.

The following is pure speculation: An interesting thought, Alistair's video shows the grounding followed by the controlled stop of the Maersk Denver followed by the Asia Rose 3 careening out of control into the Denver. There is much talk about the Suez Canal adopting the Russian GLONASS system for satellite positioning. The Denver is a USA flagged ship and experienced no difficulties while two other ships did during the sand storm. Perhaps the GLONASS system has another outage that they seem prone to.

The word on the street is that the bow is free and it’s been refloated.

https://www.bbc.com/news/world-middle-east-5655990...

Would have thought that they carry all the systems we certainly do on aircraft. Even my Nokia phone has all of them.

Reports are coming that they have managed to unstick the stern and pull it round into deeper water.

The Danish brother hasn't sent an update today.

https://www.youtube.com/watch?v=xUwWcoIlHwM

Eh, the only videos and images I can find still show the ship with a list meaning it's still stuck.

https://mobile.twitter.com/Joyce_Karam/status/1376...

Oh and the Denver is skippered by a guy called Craig and apparently he spotted the poo was about to hit the fan on the first corner and had overridden the pilot and started taking appropriate action. Which might explain the relatively controlled stop by it.

The Danish brother did say if it wasn't for the Denver it could have been alot worse.

The pilot/ Egyptian transit crew that was on board evergreen had a not very good reputation.

The radio chat I suspect would be interesting to hear. Don't have a clue what lingo it's done in or if the Rose knew something was developing ahead.

The front end is still stuck just the back end has been pulled away from the bank. They are checking the prop and rudders and if they are ok can use them next high tide to try and get the front off.

I don't trust anything being reported as I think there is a lot of coverup happening right now. I still believe the ship is very much stuck despite the stern being free. In fact, the stern was reported free days ago. I believe the truth is that the front 1/3+ of the ship is hard around and the forepeak and thruster rooms are both flooded. They may have moved the stern a few feet today but that was merely theatrical, it was already free.

I also presume that most of the public releases are face saving BS.

The brother hasn't mentioned any flooding. And haven't seen anything to indicate huge volumes of water being pumped out.

Do modern container ships have double hulls or is that only tanker's?

Recent report suggest that it may be sitting on a rock. If so, there may well be holed compartments.
Is it free?

Ever Given still in place, a bit of rotation off of the west bank. Tugs are working. March 29 7:46 GMT

From reccy mech experience you usually try and pull things out the same way as they went in.

Maybe they got it swinging then angled it for the path it went in at or least suction.

Or give enough water behind for the prop to bite.

I reckon you right though and it's sitting on top of a big rock. Wouldn't have thought there are any nearby dry docks to fix it.

After pushing into this much sand I will be really surprised if the bulbous bow is not a bit crumpled. It may look a bit like a battering ram, but it is really just designed for hydraulic loading. However as long as watertight integrity to the rest of the ship is not compromised, once the ship is floating, damage to the bow will not hinder it's ability to get to a location where repairs can be performed. As large as this ship is, there are very few locations having drydocks where this repair could be performed. It is likely that at least part of the repair will be performed with the ship afloat, ballasted to get the bow as high out of the water as is safe (from a stability standpoint).

The Dane is saying Netherlands or Japan is about the only place they can get it into dry dock.

Latest report on the news is that the wind has blown it back across the channel again!

The more you know, the more you know you don't know.

Seems to be moving now ok.

Wonder if they'll ever let it back in again....

The canal navigation document is interesting in that in that section the dredged width to 22.5m is only 137m wide. It gets much bigger elsewhere, but give this thing is 60m wide, it shows you how little room there is to manoeuvre. Also it gives the convoy speed at 16km/hr - about 8.5 knots so if was doing 13kts at the time of the grounding it was going much faster than it should have been.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

The speed is maybe explained by the recovery from bank effect requiring full power to give rudder authority.

Well, they did it.

Re the speed:
There was a report that the following ship realized that the Ever Given was in trouble and was slowing even before the 'Given hit the bank.
Apparently the second ship following was not as quick to react and collided with the following ship.
Ships don't pass in the canal, and the 'Given was not overtaking ships.
The speed was most likely the normal traffic speed on that day.

Seems Craig the skipper on the Denver the boat behind is due a fortune by everyone it was a swearing match on the bridge when he took control off the pilot. I doubt anything will be made public on what happened.

It can't be that badly damaged as its on its own and still routed the Rotterdam which is where the dry dock is.

Is the restart of the passage of ships going to be based on the order that they arrived. I know that the ships already in the channel will be given priority, but what about the ones that have been backing-up in the estuary? Will there be some attempt to prioritize which ships are given the go-ahead? What I'm thinking of are the ships hauling livestock, and maybe even some whose owners have more influence with the people running the canal than others.

Apparently safety shear pins were replaced by concrete Re bars and they went for it with the scope that the tugs were written off. The US navy contingent wanted to use bang both ends. One load on the bottom to drop the back the other to blow the rock (the dutchies told them to foxtrot oscar)

Quiet looking forward to the next time he is in the Kiwi bar to hear what actually went on.

Short of putting in a second canal running parallel to this one, what possible contingency plan could they have in place?

they are trying to do that and there is a lot of political issues over it.

Tugboat escorts for ships over a certain size would be the obvious answer but a 6 knot speed limit would be required for that case.

Alistair, there are no shear safety pins on towing gear and tugs are typically rates to operate at 100% capacity. Towing gear on ocean going vessels usually has a safety factor of 3. Damage to the ship is quite possible, though.

If even 10% of the chat of aviation or the marine guys ever goes public it will be horrendous. By the sounds of it the marine guys get away with murder being miles way from shore and only working in 2D and they can just stop most of the time.

I have seen pictures of wraps of rebars through holes in hook couples I might not be using the right terminology. But there is a pin through the hook couple that will fail before the thing rips out the deck, That calibrated pin is gone on the release. It was a bundle of rebar.

I really don't claim to have any special knowledge personally, I am just getting pictures and updates off a unlimited master qualified Danish skipper that deals with international salvage that's also Rotterdam qualified pilot.

The time constrained drama is mostly over.

Alistair, If there was anything like you describe it can only be that they were trying some shock tactics by driving the tugs fast in a slack line so generating shock loading.

Just steady pulling wouldn't generate enough force.

Any thoughts Tug?

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

The ship has too much inertia. There is nothing to gain by shocking it, just broken gear. I spent an hour swinging my 25lb hammer to try to push a 200lb pin out of our crane the other week. I finally gave up and rigged up the jack. The pin pushed out with only 10 tons. The 25lb hammer easily achieves that force but could not overcome the inertia.

Are you saying then that the static line pull from the tugs is enough to tear up all the gear?

I know nothing about these systems, but for a relatively modern ship design of that size it would come as a surprise to me if any old tug could just hook up and start ripping parts of the ship off.

The tug's gear should be able to withstand it's static line pull with a safety factor of 3.

Modern ships are built to be cheap. Class society rules make it difficult to operate ships that are over 30 years of age so they have to be disposable.


The only strong attachment points on are modern ships are the anchor windlasses. All other bits are intended for mooring and are sized accordingly. The maximum rating is usually 100 ton (coincidentally we operate the most powerful ship assist tug on the USA west coast at 96 tons on a straight pull). Only tankers over a certain size will get a "super bit" on their stern. These require a 10ft eye so we keep a special strap for when we need to attach to super bits.

If the ship went up on a rock, the rock likely punctured some compartments. That would explain the difficulty in freeing the ship.
The rock would have been stuck in the hole that it made and it would not be a matter of simple friction.
Either the rock would have to be moved, and if it was large enough to seriously compromise a ship of that size, it would not move easily.
The other option would be for the rock to rip through plating and do more damage.
Either way a lot more force would be needed to free the ship than if it were just buried in the mud and sand.
There were some reports of flooding in some forward compartments, that would be consistent with the rock puncturing the hull.

Tug, inertia or sticktion?

It would not be the same as hitting a granit boulder or even worse a lava one.
I would think that the keel would have made a groove in the rock and they could not back the ship out since the stern was against the canal wall, they hade to twist the ship and the boulder getting it of, or sucking the sand under the boulder away lowering it.

Interested in Alistair's comment above about the US opposing the completion of the double laneing of the canal. Any source for that?

Nothing from my internet search suggested even the smallest clue. I did find some indication that current shipping projections would not support the economics of the $10B project cost, but that was all I found.

The only reason I can imagine is that it might tend to lower the price of LNG and maybe a number of other things in Europe, thereby making US goods less competitive there. But that might make US goods more competitive in South and East Asia. Since that balances more or less, its LNG, and, or military concerns. ???

Can't find where I saw that one about the US opposing . It was something to do with panama canal loosing traffic. But could also have been about how they were going to finance it.

Oh remember now it was to do with oil and having two way through it would increase the flow to Europe of LPG from none US sources.

Okey so the tugboat ALP GUARD hade a straight pull of 258 tons ?

Yes, we call that a bollard pull. After construction the vessel gets attached to a bollard and pulls for all it's got with a dynamometer installed in the line. Those anchor handling tugs have controllable pitch propeller and big engines so they can make big numbers on their bollard pulls.

Sticktion or static friction must be overcome.

Quote (Tug)

Waross, if it was strictly inertia, any amount of pull would eventually get it moving so there certainly had to be some stiction involved.

Hence my question about your hammer and several tons of stiction.
In the case of the 'Given, most likely the ship rode up on the rock (Sticktion) and then the weight supported by the rock became more than the bottom could support and the the bottom plates failed.
Then the rock was inserted into the hull and formed a key, or dog.
Neither sticktion nor inertia but a mechanical interlocking.
By the way, swinging the stern would have broken the stiction.
This technique has been known by horse loggers for a couple of hundred years.
When the horse could not start a log moving, the logger would take a side pull to break stiction.
Once the log started to move sideways the horse could usually keep it moving.
But this is speculation.
There may be more information to come, and the ship may have been pivoting on the rock with no interlocking.
Is it reasonable that the rock could be supporting so much weight that it was that difficult to pull off and yet do no damage to the hull?
I don't know.

Not just a good idea;

Remember the picture I posted of the canal depth. A full third of the ship was in shallow water. There was certainly a lot of stiction involved. A dredge was brought in to dig out the bow. 20,000 m³ of dirt was removed to free the ship.

Is stiction the 'suction' force exerted to resist removal? or is it the actual bearing. I can see if the rock was embedded in the hull it would act as a giant keyway.

Everyone here seems to assume the rock was a boulder. What if it was localazed bedrock??? How does that change all the previous assumptions?? One of the previously posted sections could support my hypothesis

Seems that is still is just sand and limestone..

The logs were generally lying a full 3/3 on the ground.
The old horse loggers knew that it was easier to start the end of the log moving sideways to break the static friction and so start the log moving.
That they were able to move the stern 80 degrees but were not able to pull the ship backwards *strongly suggests that the rock or bedrock was acting as a key.
*"strongly suggests", not 100 percent but a high percentage of probability.

I'm finding it hard to believe there was a large hard pointy rock that poked through the bottom of the ship and keyed it in place. The amount the bow was into the sand and on top of sand was enough to still hold it, even when the stern could move.

Quote (Waross)

*"strongly suggests", not 100 percent but a high percentage of probability.

I don't think so.

I think until you dig into it, we (me included) just aren't used to thinking on the scale of the forces involved in moving a ship of this magnitude.

Look at it this way.... the Ever Given weighs 200,000 tons. Two hundred thousand tons. 400,000,000 pounds.

If even 10% of the tonnage of the ship (and I bet it was more than that) is bearing on wet saturated sand, the friction force alone to pull the ship out is 15,000 tons and change.

That means that if you were to just yank it out with tugs straight back, you'd need the full capacity of 38 of the most powerful tugs in the world. (Google says the most powerful tug is ~400 tons) And that doesn't even include any force due to suction, which I don't know how to calculate but I'd imagine is huge on the large area which was contacting the sand. Or the significant inertia of a 200,000 ton load which you have to overcome to get the thing moving.

The forces are gargantuan, no pointy rock required.

With the blocking of the Suez canal by a container ship for over 6-days a sense of panic is arising in the maritime community

I have a military mind. Sadly the moment I saw that gigantic container ship stuck sideways, all I could think-of was the likely on-set of a catastrophic sabotage plot.

I could visualize a single jet dropping 2-#2000 bombs mid-ship... or heavy cruise-missiles or anti-ship missiles... screaming-in and blasting the ship in-half or thirds. Based on current experience, cleaning-out the debris [containers] and cutting-up the ship would take at least 4-years. Something like this might even require re-routing [digging] the canal AROUND the blockage and closing that section off indefinitely.

This should be a wake-up call for every major and minor country that relies on canals or waterways or bays [with necked entry water-ways] for an economic lifeline... and have giant container/cargo ships passing each other.

I mean... once you’re adding #2000 bombs and cruise missiles into the equation... does it really matter if the ship is stuck at that point? Just sayin’.

Yes, the 'rock' was a furphy, a figment of someone's imagination. Ever been through the Suez? There is nothing but sand.

Then we had folks on this very site advocating for blowing the ship in place, or dumping the cargo in the canal.

Ludicrous, and some of these folks are the same ones who insist on 'following the science' in other respects.

Here's a few more to worry about. Sweet dreams.

Actually there are some high cliffs to the west of Suez. Finding a rock isn't totally impossible.

And in this part of the world, Singapore, all of the South China Sea, Taiwan Strait, Sydney Harbour, Port of Busan, Port of Yokohama...the list goes on.

...and then, there's the breaching of dams (tried and true war tactic)

You and I must be looking at different threads.

I did see some people with practical experience on this matter suggesting that the reporting of the incident wasn’t honest and that the situation was much more dire than it turned out to be. Yeah, they had suggested off-loading the ship and/or cutting it in half. But not a whole lot of talk otherwise of “blowing” the ship in place or wholesale “dumping” of the cargo in the canal.

I did suggest a nuclear option, but not seriously.

The ship's black box is reportedly on the way to be analyzed by US NTSB.

Why use explosives that requires a degree of air superiority and is relatively overt, a software hack might not be. A software hack did cross my mind when it a first appeared to be an uncommanded turn. At a guess if all the systems are centrally computer control one could have made it rollover and ground at the same time (one big bit could be harder to remove than lots of little bits). Just think of all those vessels built in the PRC.

The rock was compacted sand which would brake up if you soaked it in water for a day. It would break up in lumps but if you worked it with your hands it would turn into sand again.

The tug with the RE bar instead of a shear pin is a hook puller not a bollard pull. Its so they don't need anyone to catch the hawsers they just lower the hawser down into the hook jaw mouth and then it gets hydraulically closed then when they want to drop it they open the jaw and its released. The salvage guys like them apparently because if things get exciting they can hit the release and get out the way quickly

So then it is more likely that the keel hade cut into the sandstone, as when you fasten an ax in a chopping block.
And to get it loos it was more like, trying to unscrew a loctited screw with an oversized screwdriver until the groove in the screw was broken?

I heard with the polar ice cap melting, a new northern route may open up that is shorter than using the Suez. Perhaps we just wait. Shouldn't be much longer now...

Seems Russia smelled a marketing opportunity and is promoting the Northern Sea Route as THE alternative to the Suez. It's not hard to envision the geopolitical implications of a major shipping route controlled by Russia, let alone the impact to the environment. It seems to me that Russia is the big winner out of all this - besides The Dane of course

https://www.washingtonpost.com/world/russia-suez-t...

Quote (WaPo)

MOSCOW — Russian officials are seizing on the Suez Canal blockage saga to promote its Northern Sea Route, an ambitious infrastructure plan being pushed by President Vladimir Putin that aims to capitalize on the polar ice melt from global warming by opening up Arctic shipping and development.

Russia’s Energy Ministry said Monday that the days-long blockage of the canal by Rotterdam-bound Ever Given — a drama that is finally winding down as the ship began moving again — showed that its Northern Sea Route (NSR) and gas and oil pipelines were reliable, secure and competitive “in comparison to alternative routes.”
...
As Suez traffic choked to a halt last week, Russian officials were busy promoting the NSR.

Nikolai Korchunov, Russia’s envoy for international cooperation in the Arctic, said Friday that the Suez Canal blockage should press the world to look at the NSR as an alternative.

“The incident in the Suez Canal should make everyone think about diversifying strategic sea routes amid the increasing scope of sea shipping,” he said. Korchunov added that there was “no alternative” to the NSR.

In 2018, Putin decreed that cargo traffic along the route should be sharply increased — to 80 million tons by 2024. Cargo volumes reached 30 million tons by the end of 2019 and 32 million tons last year, according to the state nuclear corporation Rosatom.

That might work for the East Asia / Atlantic/EU trade, but the Northwest Passage looks better for East Asia / North America. Not going to do much for any other routes, No way will it replace Persian Gulf / EU/India/Africa routes.. There have been investors looking at building a port in Hudson Bay for years now, in anticipation of more ice free waters.

https://youtu.be/oWF7A9Ujr3w

Seems they have just ordered another 20 of these ships.

If you look back at the survey drawing tug posted on the 27th March, it seems this section of the canal has the main channel offset to the west, but there are several what appear to be deep cone shaped sections where my guess is the suction dredgers have been able to suck out sand and loose gravel etc, but left a number of what might be harder sandstone or maybe even just clay and sand pillars which had been mentioned.

These vessels are essentially flat bottomed so it would appear that the vessel rode over one of the humps and didn't stop until the nose ran into the bank.

Then with the nose now out of the water by a number of metres you have a large area of softish sand / clay / soft rock underneath the vessel some distance from the bow stopping it moving due the huge weight of the vessel and its cargo.

So excavating some of the material helped, but in the main the rear shift sideways pivoting the vessel on this harder lump was the key, a bit of rear ballast apparently once the rear got free, but not enough to snap it, and then a high tide and some associated higher currents and some almighty ocean going tugs and off it slid.

Will be interesting to see if the bow thrusters were operational.

By all accounts on these big boats the thrusters are pretty much useless at anything over 0.5 knts. And even then if the wind is coming from the wrong direction the boat will be blown sideways and they won't stop it.

Allistair, the unique feature of an anchor handling winch is having multiple drums on the winch. One drum to haul the anchor and one drum to tow the oil rig. This rebar story is bogus. All towing gear is high strength steel (improved or extra improved plow steel) which rebar is not.

this isn't a winch its a bloody great hook Its on the tug not the boat. It slides around 180 degs left to right on a track. The salvage master can dump the hawser under full load with no input from the vessel being salvaged. Press a button and bang and its gone.

It looks like this but about 5 times bigger.

it also hardens up as well when LPG exports are concerned. AKA Nordstream 2 is stirring up again as it get nearer to completion.

Nordstream II has been 95% complete, but dead in the water for over a year. Work stopped when USA authorised use of sanctions on all companies participating in any way on the project, even the German harbor that some of the previous contractors were using to support their operations. Only some 100km remain to be completed. The USA sat by doing nothing, except spouting the usual threat of sanctions, while Russia moved into Ukraine, then all of a sudden, and entirely coincidently I'm sure, with the advent of US LNG export capacity, sanctions became imperative and all work stopped.

Err they started laying pipe in 2018 and put down 1100 km of it.

And they were gearing up for completion October last year.

Germany's energy plan hinges on it being complete. Short of starting ww3 blowing it up I can't see it being stopped.

All routs have there problems, you might need a combined tugs and icebreakers.

Have a Google for great circle navigation and Mercator charts.

You certainly will see no advantages to any polar route looking at a Mercator projection map.

Yes, you are right. The Fortuna is working. I didnt know that. I also thought that no harbors were openly cooperating, so they must be going very slowly if they are getting their pipe and consumables barged to them from a Russian port. Last I heard was that Germany was complaining, but complying with US demands.

Here is a good visual of the routes:

You're right, shortening shipping routes from Chinese ports doesn't mean much. That only accounts for 7 of the 10 largest ports in the world by tonnage per year.

NEW YORK Suez Canal Resumed Operations : What Will Happen to Ever Given? | Chief MAKOi

On the big blue marble ... Distances can be deceiving.

Ho Chi Minh City, Vietnam is exactly 16,500 km to Rotterdam, by either route.

From Australia, neither route has any appreciable advantage in distance over the other..

Strangely enough, for Asia to Rotterdam OR NYC, the Northwest Passage is also nearly equal to the Bering Strait- Iceland route.

Sydney to NYC is only about 1000km less going through Panama then using the NW Passage.

Sao Paulo to Suez is the same distance through the Med or passing down around Good Hope.

NYC is the same distance to the entire east coastlines of the North Atlantic Ocean, from Boda, Norway to Senegal.

And for what its worth, NYC to Panama is the same distance as NYC to Houston.

Hokie, edited to address your comment. Thanks.

Now that the 'Ever Given' has been unstuck and traffic in the canal is moving once again, it appears that QAnon followers may drop a conspiracy theory which was starting to develop among the unhinged. Now it was never really made clear what the theory was actually built on except that there had to be a reason behind this obviously well-planned 'accident'. After all, it had a world wide impact. It involved something that very few people had any first hand knowledge of or experience with, always good when dreaming of good conspiracy theory. And last but not least, Hillary Clinton was involved. HUH!!!!

Well, after all, during her years as the First Lady, the Secret Service code name for Hillary was 'Evergreen'. It was written on the side of the ship in big bold letters. And what more does a group of QAnon nutcases need to convince themselves that they're on to something? However, since the crisis is now over, and they didn't need to destroy the ship, and whatever secret cargo it might have been carrying, and nothing happened elsewhere in the world as a result of this six-day drama, it must have been a false alarm. But for many of the true believers, they really thought they had nailed it this time.

Note that this is not an April Fools joke, there actually was a lot of conspiracy theory buzz out there on the fringes, including the above QAnon near-orgasm, as to what this was really all about. Even here in this threa, there was speculation about potential military players, state-supported or otherwise, involved in this incident. And if not this time, talk about this giving those parties ideas for next time.

Not about QAnon, because I'm not interested in such nonsense.

You post propaganda as fact. That's why you need the mirror. This conversation was proceeding intelligently until you dropped your conspiracy theories in it.

The Northern sea route is more to do with the Mere De Kara opening up to tankers for crude and LNG I suspect.

A nuke reactor on a boat solves the power issues up there and they have already cracked that one.

So again it comes down to energy.

This has been a part of the buzz all week, just like the series of posts here, in this thread about 30 hours ago, talking about the geopolitical implications of blocking the Suez as well as dozens of other waterways around the world. There wasn't much factual support for that as well, but then that's the nature of the instant and collective discussion of events in today's connected world, and since none of us here represent ourselves as 'journalists', I guess we're each allowed to offer for discussion what we feel is of interest, and since I didn't make this up (I've provided my sources)...

Besides, with this crisis now over, a little humor about why some people were following it as closely as many here were obviously following it, I thought would be enjoyed, if for no other reason than that it demonstrates that everything that happens now days is fuel for someone's beliefs, factual-based or otherwise.

John, I did not read your post as furthering Q conspiracies. In fact, I took it as you obviously meant it, to discredit such nonsense. I can't see how anyone else could have read it differently. I didn't know that Q had made a case about it, but that isn't surprising given the amount of meds it must take to fuel their collective imagination.

LNG potential. 13,500 Km from Virginia to Japan is roughly equal to Qatar to Japan, but Qatar gas is probably better priced. Norway and Algerian LNG may gain some advantages with a polar route to Japan, but would likely be undercut by Australian gas. There are some large gas export plants in development in East Africa, so future competition will be tough for anyone west of Qatar/Suez. The best foreign market for US LNG is in fact only the northern EU region, anything above the Tower of Hercules. hence the sanctions on Nordstream II.

Anna, you are truly unique. Color blindness is rare among females. Granted, it's rare among males as well, but much more so for gals.

The most common form, Deuteranomaly (a type of Red-Green color blindness) effects approximately 6% of males but less than 0.4% of females. My father had a severe case of Red-Green color blindness. He always joked that that was why he was such a good shot. Because, when deer hunting, he had to make the first shot the kill shot because he wouldn't have have been able to follow a blood trail, unless of course it had been snowing, then who cared what color the blood looked like. Of course, if it were snowing, I'd follow the tracks

Note that my interest in the issues of color blindness was not really because my father's situation, but rather it came about when I was the project manager for a major update in our software user interface and we needed to make sure that it was usable by people who were color blind, so I did a bunch of research on the topic. This included finding a set of color charts that compared what a color blind person would see versus someone who was not color blind. So we had to make sure that when we used colors to indicate something in a menu or say highlight a choice, that we avoided using colors that a color blind person would find hard to distinguish. Obviously you would avoid changing something from Red to Green, or vice versa, to indicate a state change or an option being set. And it could also be an issue when people used a lot of colors for components in their CAD models and while we did offer photo realistic rendering, that usually required a lot of computer power (or at least it did for a long time before the 'Gamers' got the hardware people to produce miracles in silicon), so most people stuck to a form of the RGB color palette. In our case, we used one based a cube made up of six layers, each layer consisting of six x six colors, for a total of 216 colors. Black and White occupying opposing corners, and the remaining six corners being assigned the primary and secondary RGB colors of Red, Green, Blue, Yellow, Cyan and Magenta, with all the variations in between. In fact, I even wrote a program that our customers could run on their models so as to temporarily show them what that model would look like to a color blind person, in case that was something they needed to concern themselves with.

1503 what's in that Mere De Kara region? I have heard about it off and on for years.

Admitally mostly to do with nuclear waste dumping and isotopes washing up in Scotland but later on there was definitely something to do with oil, gas and coal.

Quote (John)

He always joked that that was why he was such a good shot.

Well he probably was.
The reason they think men are more often colorblind then women is because colorblindness gave men an advantage when hunting.
Being colorblind gathering fruits and food items is not an advantage.
Colorblind have the same eyesight as prey animals, they detect movement much better, they do not get confused by the camouflage colors the animals have, so colorblind people can spot animals long before people who can see color.

I think mostly just hopeful prospects. I don't know positively that they are producing anything from any offshore reserves in Arctic waters at this time.
One thing for certain is that no Arctic ice is a boom for Russia. It has kept them bascially landlocked since the dawn of history. Any opening up there and ..well ... they'd be a totally unleashed kid in a candy store. I can easily imagine that Russia has been pumping out as much CO2, hexaflourines and flaring as much methane as possible to try to get a global warming bonfire burning as fast as they can.

Seems the Fortuna is laying about 20km a month and has just been joined by the Akademik Cherskiy.

120 km left until its complete.

Reckon Merkel will get it complete then go.

On a different note divers have inspected the hull and there is light to medium damage what ever that means, but they think it will be able to self navigate to Netherlands.

But basically its stuck in that lake until a load of money has changed hands.

Nordstream has been stuck on that same "120km to go" for the past year. They must be laying in circles. Hey, that actually happened in the GOM at least once.

Merkel is doing some dancing, mostly to US sanction threats. The puppetmaster supreme pulling all the strings is former German Chancellor 1998-2005, Hr Gerhard Schröder. Schröder is currently the chairman of the board of Nordstream AG and of Rosneft, How's that for geopolitical pipelines? In fact that's much bigger than any coup that GW Bush and Dick Cheney ever dreamed of pulling off. Germany is walking an extremely tight wire on this one.

I'd think the canal authority is responsible for all salvage and losses if there were no mechanical failures and a canal pilot was piloting the ship.

Lionel, patience. Let the black box tell its story.

Nordstream 2 was 160km at Christmas.

And they have finished the German end in the last 2 months.

Lionel, they're already asking for money.

https://gcaptain.com/egypt-compensation-suez-block...

After hearing about the captain of the Denver having to override the Canal Authority pilot while the ship ahead and behind both crashed really does make one question the competence of the pilots. Pending investigation it seems Egypt should be paying the rest of the world. I doubt that is going to happen, the investigation is being performed internally by Egypt.

The second story https://gcaptain.com/shipowner-declares-general-av... is also very interesting.

Basically the ship owner now wants all the owners of the cargo to fund part of the cost of "saving" the vessel and its cargo. And if they are not insured or can't pay the container and its contents is seized.

With 20,000 containers (or is it 10,000 normal containers and 20,000 TEUs?) that's a major headache for everyone.

Did the salvage go Lloyds open contract?

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Lionel,

I'm not sure if it was earlier in this thread, but the Suez pilots, like nearly all other pilots, do not take control of the vessel. The captain retains responsibility and actually gives the orders to the helm and engine. Of course if the captain ignores the "advice" of the pilots and then runs aground or hits something then he is clearly at fault, but even if he does everything he is asked then its still his fault.

The only pilots who take responsibility apparently are the Panama canal pilots.

I think they will end up with a limit on ship size if the weather is predicting high winds or high gusts.

Remember - More details = better answers

From a lengthy write-up in the Post about this. A good read if you have access to it. Goes into great detail about the recovery process too.

https://www.washingtonpost.com/world/middle_east/s...

Quote:

At 7:08 a.m., with the sun an hour above the desert horizon, the Ever Given moved into one of the canal’s one-lane arteries and approached a bend to the right. Satellite data shows the ship started to weave from bank to bank at more than 15 miles an hour, much faster than the canal’s speed limit of less than 10 mph.

What was happening on the Ever Given’s bridge, where the captain and two certified Suez Canal pilots were on duty, remains a mystery. But some maritime and canal officials have noted that a wind of up to 35 mph was blowing from the south, pressing against the wall of containers.

For more than half an hour, the ship veered from side to side, according to the satellite tracking, narrowly missing the banks until its stern seemed to brush the left-hand shore. The bow instantly sheered sharply to the right, and 400 million pounds of ship plowed into the sandy eastern bank of the canal at 13 mph.

It was 7:44 a.m., and the Ever Given was lodged stem to stern.

Well I haven't bought anything from IKEA , lucky me.

I have to query this.
Over half an hour at over 5 MPH above the speed limit?
She didn't overtake any ships?

She should have been a couple of miles ahead of following ships.
I suspect that "Speed limit be dammed" she was moving at the speed of the normal traffic.

If we have learned anything from this fiasco, it is that the unbridled dictatorship of Egypt is responsible for not operating the canal well, unbridled european capitalism is responsible for the backlog of ships needing to go east, and unbridled Chinese communism is responsible for the backlog of ships needing to go west.

1 arc minute not 1 arc second.

For those questioning the speed (or the Post’s reporting for that matter), or what the other vessels nearby were doing; from another source:

Quote:

Those piecing together what caused the accident will undoubtedly look at speed. The ship’s last known speed was 13.5 knots at 7:28 a.m., 12 minutes before the grounding, according to Bloomberg data.

That would have surpassed the speed limit of about 7.6 knots (8.7 miles an hour) to 8.6 knots that is listed as the maximum speed vessels are “allowed to transit" through the canal, according to the Suez authority’s rules of navigation handbook posted on its website.

Captains interviewed for this story said it can pay to increase the speed in the face of a strong wind to maneuver the ship better.

“Speeding up to a certain point is effective," said Chris Gillard, who was captain of a 300-meter container ship that crossed the Suez monthly for nearly a decade until 2019. “More than that and it becomes counter effective because the bow will get sucked down deep into the water. Then, adding too much power does nothing but exacerbate the problem."

Bloomberg data also show that the 300-meter Maersk Denver traveling behind the Ever Given also posted a top speed of 10.6 knots at 7:28 a.m. A spokesperson for Maersk in Denmark declined to comment. Ship captains and local pilots said it’s not unusual to travel through the canal around that speed despite the lower limit.

The Cosco Galaxy, a container ship marginally smaller than the Ever Given, was immediately ahead and appears to have travelled at a similar speed, though with a tugboat. The one ahead of the Cosco, the Al Nasriyah, also had an escort. The escorts are not mandatory, according to the Suez authority’s rules of navigation, though the authority can require it for ships if they deem it necessary.

“The biggest vessels often travel with a tugboat in close proximity, an escort boat, to facilitate the transit," said Captain Theologos Gampierakis at commodity trading house Trafigura Group in Athens.

A cargo ship with containers stacked high like the Ever Given can be particularly hard to navigate since the ship’s hull and wall of containers can act as a huge sail, said Kinsey, the former captain, who made his last trip through Suez in 2006 .

“You might find yourself positioning the ship in one direction, and you’re actually moving in another direction," said Kinsey. “There’s a very fine line between having enough speed to maneuver and not having too much speed that the air and hydrodynamics become unstable. Any deviation can get real bad real quick because it’s so tight."

About 20 minutes after the incident, the first of two tugboats accompanying the vessels ahead of the Ever Given came back to push its port side in an effort to dislodge it, according to data compiled by Bloomberg. Later, eight tugboats were deployed to push both sides of the container vessel, but to no avail.

As 1503-44 noted above, the speed limit is 16 kph ordinary vessels or 9.9 mph. And 13.5 knots is 15.5 mph. Both of which are what the Post reported.

Your right 1 minuet of arc.

Been getting on for 20 years since I did nav general. Its a good unit to use for navigation allows loads of in your head calculations to be done on the fly. Although i must admit on modern aircraft we don't do it very often these days apart from distance V height for a 3 deg glide.

When I was doing my internship some years back I was on a speedy steamer. The maximum maneuvering RPM was some 75 rpm (full ahead) but the plant could readily make 100 without getting in to extractions or anything and the pilots knew it. We'd routinely get phone calls from the bridge asking for 100 rpm in San Francisco Bay (17 knots). I remember hearing a complaint about our wake going over pier 39 and getting the tourists wet.

She was a sporty girl seen here on her way to scrap. The ship has s destroyer stern where the prop had a strut bearing which was unusual for a commercial ship. Cruise speed was 24 knots at 790 feet. I'll never forget th color red on the chief engineer's face when the chief mate managed to dial in 20 degrees of rudder at 24 knots during a loss of steering drill.

I used to scuba dive off an old clyde tug in the clyde near Glasgow . She went quite fast as well. They had stuck a compressor on the rear deck.

She looked like this.

That's a lot of stern. Naval architects are getting spoiled with z-drives and don't put the attachment points far enough forward on boats anymore. With the attachment points close to the steering there is no leverage and we can't pull and steer at the same time from the stern. As ship assist vessels we hardly ever work from the stern but we carry a rescue advertisement.



See the big deck on one of the most legendary towing vessels ever built, the Crowley Invader class. It's a Spaulding design and the Sea Robin and such were part but had less horsepower. The Invaders had 20 cylinder EMD engines. I operate a Spaulding boat built as the Phillip W and is currently called Patriot. That thing is a work of art compared to everything else I have come across. Spaulding was famous for using triple rudders and I know why but most of the industry doesn't. 3 rudders lets you move two outboard so they act as nozzles and give better bollard pull numbers while still maintaining nearly the maneuverability of a 2 rudder setup.

Then, Crowley partnered with a naval architect firm to design these lumps. I might operate one so I'm going to have to delete this post if it gains traction.

Nice point about the tow point being too far aft and over the rudder. I can see where it could be useful to be able to steer while towing.

It was great to dive off even with the compressor on it and quads of nitrogen for making nitrox. Loads of room for kitting up and moving about. The toilet was brutal though by far the worst I have every used on a boat. And getting back onboard was very stress free. It was set up for commercial ops and there was room for a chamber but they didn't have it onboard for us.

I grew up in Aberdeen and went for regular walks on Torry Battery. Always loved watching the marine traffic in and out of Aberdeen harbour.

Seen that one and its utterly colossal.

In 2018, when my wife and I did our four-island cruise in Hawaii for our 50th wedding anniversary (it was actually our 51st, but we had had to postpone a year due to my heart valve replacement surgery), one of the things that I spent time when entering and leaving the various ports was watching the different tug boats that we'd see. Now our ship itself didn't need any tugs, or at least I never saw any used to move our ship, the only thing close was just before we left Honolulu, a tug was used to move and then take away the fueling barge that was servicing our ship:


September 2018 (Sony a6000)

This one we saw that may have been escorting us into Hilo, on the Big Island:

Here's that same tug, the next morning at it's morring:

And I watched this one as we left Hilo:

And we saw this one in the harbor on Kauai:


September 2018 (Sony a6000)

And as we were waiting to disembark when we got back to Oahu, we saw this rather small tug towing a tourist submarine out of the harbor on one of their underwater excursions. I guess the sub, which actually did do a real submerge and was self-powered (we considered taking one on these rides but we got to the islands just as a hurricane had passed and they had suspended their scheduled trips and they didn't restart them until after our cruise ship had left and we only had one day in Honolulu after the cruise, so maybe next time) but I guess they only have enough power (they were electric) to handle the actual dive and underwater exploration, but didn't have enough power to go back and forth, from and to the port:


September 2018 (Sony a6000)

We watched several of these come and go as we waited for our assigned disembarking time.

John, I love you sometimes. You posted pictures of Tiger tugs from Hawaii. We operated one for a minute. They're the worst boats ever built. Don't get me started on the plywood deck plates set 12 inches below every frame (3 feet spacing) so you can't walk through the engine room and a 5 ton rated winch on a 50 ton boat. Worst boats ever. The one called Freedom in your picture waa ours. I reconfigured the brake band on one drum so it could hold the pull. I also installed 3M Crystalline window tint on the wheelhouse to keep the captains from melting.

There definitely seems to be a difference of opinion across the pond on how to attach the tow hawser.

The big ones in europe with a winch have a BOP style hydraulic shear setup to cut the hawser remotely and the smaller ones that hook setup. That old clyde tug must be 1950's built and it has a quick release hook although that one was manual with a rope that to that passage way behind it.

Tugboateng please don't take this as a pissing match comment. Genuinely interested about the different philosophy's. I am happy that things are done differently either side of the pond, now more interested in why.

Love it!!! sounds like me talking about BAe Jetstream 31's, only people that argue with me is Metro pilots and technicians.

Do boats have a decking material. I suspect the steel deck would get quite hot in the sun... also some interesting thermal expansion effects... hot on top and cold on bottom.

Allistair, the company that built that Tiger class of vessel bragged about the architect's ability to design a boat on a napkin and it showed. It showed at every level from building an 80ft boat that required class approval when 78 feet didn't, Winches from swampy Louisiana that didn't make 19% of the 3:1 safety factor, and German z-drives and their confused sourcing of parts. Our sister company pulled the bullnose off the deck and the class society gave it an as constructed rating of 15 tons on a boat that could pull 55 tons.

A safety factor of only 1.5? Are Z-drives common... they appear to be mechanically inefficient...

I did a elective course for a year on marine architecture didn't go near it again afterwards. Find boats very interesting though.

Once took a Captain of one of the channel island cat speed ferries on the jumpseat to get him out the the islands due some illness. When I was leaving CI at end of contract taking my car back to the mainland I ask one of the stewards on the pax decks if he was the boss that day. Turns out he wasn't but the skipper knew about the trip and I was on the bridge for the whole trip and loved it... Especially the banter with the duty engineer on the bridge.

Not just a good idea;
It's the LAW!

Allistair, in the US, all boats have the hawser on a winch. Towing forces are transmitted to the vessel through the brake band. Some newer vessels have hydraulic or electric render recover modes and can tow without using a brake. There are few of these in the USA.

As for releasing the tow, with the exception of some low rent companies, the vessels have winches that can be free-spooled to ditch the tow in an emergency. The end of the hawser is fastened to the drum with a ssmallerline that will break when the hawser is dumped.

The horsepower of modern board is so great even the synthetic ropes are too heavy to handle by hand.

Dik, the nozzles z-drive is the most efficient methods of turning horsepower into bollard pull. Conventional boats drift with the current while pulling so you'll have to stop periodically and reposition the boat. There are boats with drives on the bow, most on the stern, some on either end. Each arrangement has advantages and disadvantages.

Interesting, I can understand why they do it with a hook this side of the pond I have seen a hawser start to part and they dumped it and it shot back and whalloped off the side of the vessel being pulled. No great lengths of cable in the water to foul things up and the tug has instant free movement.

Plus if marine ropes are anything like land based winch cables its an expensive and utter pain in the bum to keep them certified. And if you just have a hook which the hawser drops into you need less man power as well. The big boys have a small capstan winch to pull the hawser in via a messenger if they can't get under it.

Thanks for the z-drive info... square cut crown and pinion? Braided polypropylene? size?

If you mean when I saw it?

Diameter of my calf and it was some form of dead rope with a weave outside. It was a klondyker about to get sucked through the pentland firth. 20 min later one of the big boys from Shetland turned up and took it under tow with something twice as thick.

We weren't close so I don't know what they saw to trigger its release. We just saw it springing back towards the russian and the skipper of our boat, another dive boat from scapa. said that hawsers just parted.

dik, z-drives all run palloid gears top and bottom. I've got a box open right now, I'll get you a pic of the upper gear shortly.

In USA ship assist tugs use some flavor of UHMWPE for the rope. Spectra and Dyneema are the dominant strands. In our fleet we run Samson Rope's Saturn 12 in 2-5/8 inch diameter.

For Allistair, the weak link.

Palloid gear.

The Ever Given is 'stuck' again, only this time, it's not on a sandbar, but rather by red-tape. It seems that the Egyptian government doesn't think the owners of the ship are fully coopering and until inspections are done, including an examination of the 'black box'. Until then, the ship is stuck where it's at:

Yes, the level wind. Something interesting to keep in mind, for wire winches the level wind is geared to neatly lay the wire across the drum but soft lines tend to bury themselves in the layers when you pull. In this case, the level wind is geared very quickly so that the line lays in a criss cross pattern on the drum

drum... ya, that's the word. Thanks... I didn't realise the cross pattern... keep the rope from embedding itself in the lower layers.

While this is not a marine application, an alternative method is to just have a big enough drum that you just lay a single row of cable, in this case, a mine lift hoist at the Quincy Mine in Hancock, in Michigan's Upper Peninsula. It was installed in 1918, and was used to lift mine cars from, at the time, the deepest mine shaft in the world. The drum, which is spiral grooved, had a capacity of nearly 11,000 feet of cable. The mine shaft, Quincy #2, had an angled (55˚ from vertical) shaft length of 9,260 feet (vertical depth of 6,200 feet) and the hoist could lift 10 tons of copper ore at nearly 36 mph. The hoist was built on what at the time was also the largest single block of reinforced concrete in the world, 3,200 cubic yards. The mine continued to operate until 1945, when the dramatic drop in the price of copper after the end of WWII, no longer allowed the mine to operate at a profit.


October 2010 (Sony DSC-H2)

This is the Quincy Mine Hoist House where the hoisting machinery was installed:


October 2010 (Sony DSC-H2)

And this shows that Quincy #2 Shaft House. Note that the steam plant had been demolished years ago:


October 2010 (Sony DSC-H2)

And here is the Quincy #2 Shaft House. Note that slope of the large section of the roof shows the angle at which the shaft went into the ground. The reason for angle is that the shafts were cut to follow the geological angle of the strata, shafts than ran out horizontally from this single angled shaft. There were dozens of similar mines in the area, and they all followed that same angle. Note that Quincy #2 is the best preserved example of copper mines in the area, which was originally opened for operation in 1868.


October 2010 (Sony DSC-H2)

This shows a typical piece of 'float copper', often found in the area. The copper taken from these mines was pure ore. There was no actual 'smelting' process, only the mechanical separating of the rock from the pure copper, which was then melted and poured in ingots for shipment.

Pure ore? That must have been quite an asteroid impact.

I wonder what the purpose of the tapered ends was? Soft start and soft stop?

interesting stuff thanks for real life close ups.


Courts in international transport are a bit of nightmare.

I feel sorry for the crew of the evergreen. They will basically be held hostage until its all sorted out.

Yes, back in 1918, it was easier to run the drum at a constant speed and use the geometry to control the speed during the trips up and down the shaft. The speed control was basically start and stop. Here you can see part of the powerful braking system. There was a duplicate on the other end of the drum:

As for the ore, remember this mine sets just a couple of miles from the shore of Lake Superior, the largest body of fresh water the world. Four of the five Great Lakes were formed by thin spots in the Earth's crust, which collapsed and formed deep fissures (Lake Erie was not formed like that). In the case of Lake Superior, the crust was either extra thin or the collapse extra deep as magma from the Earth pushed up pure molten Copper, forced up through the gaps in this Geo-structure, thus the seams of pure Copper, and a small amount of Silver and Gold, minuscule in comparison, but there none the less (all three metals always appear together, with one of them being dominate by an order of orders of magnitude compared to the other two).

And Lake Superior is very deep.

John, Lake Baikal and Tanganykia are larger. Baikal by about 2x.

And, since my grandfather mined copper with Calumet & Hecla up to the early 60's, I have read quite a bit about the mining activity there. As you probably know, the Superior region's geology is very old dating back 1 billion years and is complicated by some 30 lava flows alternating with sedimentary layers. Sometimes flowing one direction, than another. I was surprised to learn only a few years ago that the copper and other minerals actually were formed after surface volcanic flows halted and the minerals having entered the most recent sedimentary layers by percolating up from below as the Superior anticline subsided, forcing up solutions of hot water from which the minerals precipitated upon cooling. I had long imagined that they had been deposited from intrusion of molton, pure elemental, metallic materials.

To get this thread back on track a bit, this is an interesting piece explaining some of the issues. https://www.theguardian.com/environment/2021/apr/0...

A key one for me is that the ship in front which was reckoned to be about as big didn't have any issues with the wind...

These are supposed to be winds for March 23 AM over the Suez. I found these posted elsewhere but don't know what app or website generated them. It doesn't look like the Ever Given was necessarily subjected to cross winds.

I don't know, I've swam in Lake Superior and it's damn cold. The story goes that if you drown in Lake Superior, they might as well put your headstone on the shore because your body will never be found. It's not warm enough for decomposition to create sufficient bloating for the body to float.

Another tidbit, despite it being so far North and the water being so cold, it's very rare that Lake Superior ever freezes over during the winter. It's just that the lake is so large and contains so much water, that by the time the water temp reaches 32˚(F), it's Spring and the temps start to rise.

Well that was interesting. National Parks Service says freezes twice a century. 1979 and 2014.

It seems that it freezes 95% quite a lot. Some say that's enough to qualify as full.
Some also say that has happened 5 times in the last 20yrs. Others, once. Hey, what's 5%. That's a pretty big ice cube, no matter which way you look at it.

Quote (https://www.freep.com/story/news/local/michigan/20...)

Lake Superior nearly frozen over: 90 percent+. Only the fifth time in the last 20 years the big lake has exceeded 90 percent ice cover. In 2014 and 2015, ice covered more than 95 percent of the lake. The last time Superior froze completely was 1996. NOAA satellite pic from 3-7

Yahoo says 1962 as well.

Mr Google is pumping out the statistics now!
Calumet has the oldest, still in use, ice hockey rink in the world. No wonder.

And ... due to climate change, Superior may not have any ice by 2040. ???

The thickness of ice may only be 2 or 3'...

And when the lake doesn't freeze over, that's when they break snowfall records. Unfortunately, they've had a very mild Winter so far with just over 131 inches of snow (this is at the school in Houghton):



The year I graduated, 1971, that winter, while we didn't set a record for total snowfall (but we did get nearly 280 inches), we did set one for the longest continuous snowfall, 52 days. Now that does not mean that it actually snowed continuously, just that it snowed a legally measurable amount in a 24 hour period, every day, for 52 days. It was like living in the tropic, except instead of getting a heavy rain shower every afternoon, we'd wake-up every morning to two or three inches a fresh snow.

Now I say 'legally measurable amount' because in the state of Michigan they allocate additional highway funds for snow removal based on the number of days in which a county had a 'legally measurable amount' of snow, so keeping an accurate record of stuff like that can mean big bucks for the local county road commission.

More humidity from the unfrozen surface = more snow. Most houses in Calumet and Laurium have entrances on the second floor for winter access.

That looks like the Ventusky app. https://www.ventusky.com/
AFAICT (I use it as my main weather app) it doesn't let you view historical data.

The icon in the upper right (showing wind speed) notes that those particular screenshots are from the DWD ICON model: https://www.dwd.de/EN/research/weatherforecasting/...

It really is.

Question. On https://www.ventusky.com/, wind gusts are reported as Maximum 1 hour.

The usual definition is

Quote (https://graphical.weather.gov/definitions/defineWi...)

Is a sudden, brief increase in speed of the wind. According to U.S. weather observing practice, gusts are reported when the peak wind speed reaches at least 16 knots and the variation in wind speed between the peaks and lulls is at least 9 knots. The duration of a gust is usually less than 20 seconds.

If they are meaning sustained wind for 1 hour, that has a much more significant impact on the ship maneuvering, than the 20 second gust.
Increments on the time slider are 3 hours.

I found this historic weather report from Suez,.
If the Ever Given was going 13,5 knots against 5,94 knots north-northwest winds the actual speed was 7,56 knots or ??

Ever Givens speed 13.5 knots________Speed limit Suez 14 km/h ___________Wind 11 km/h________________________Wind gusts 15 km/h

Your getting confused with your aircraft stuff.

The ships reference is the water not the air. But they will take it against the ground reference. All the speeds on the AIS will be ground speed off GPS.

If the tide was pulling water north then that would decrease its ground speed and south it would decrease it.

The rudder authority is determined by the speed through water.

Thanks Alistair.
Your right I am confused
Well I guess that was to exact to be true.

You mean.
SOG, 10, Speed over ground, in 1/10 knot steps (0-102.2 knots) 1 023 = not available, 1 022 = 102.2 knots or higher.

If there hade been no wind at all and he hade been following the rules he hade been going 7,56 knots now it seems that he added the wind speed that he was going against 5,94 knots ending up at 13,5 knots.
Just coincident or is there some logic in that?

Best regards A

“Logic will get you from A to Z; imagination will get you everywhere.“

Ships you have to work with water speed to get the speed over ground not wind. Because the ship travels through the water

We noticed that the ground speed was 0...

After reading about the evergreen my news feed is giving me marine news...

Which to be honest is no bad thing

https://www.swzmaritime.nl/news/2021/04/06/smit-sa...

Load shift and rough weather. This time SMIT is off to save the day.

Didn't see the point of creating a new thread.

There are some old books about sailing on boats with actual coal bunkers. "Captain Jan" comes to mind where the experienced captains were able to feel the change in roll to know when the vessel was becoming dangerously unstable. Roll on Roll Off ships are notorious for getting their ballast wrong and ending up on their sides. I am surprised there is no accelerometer based system to alert crews their ship is not stable. In this case, seeing the way the ship rolls, it may be on its side but it's seems very stable. I can understand a crew evacuation because beds and dining tables don't work at such angles, stairs become quite challenging too. It doesn't appear that the ship itself is in danger, though. That's good design.

Some of the load came adrift and shifted. Which appparently made it unstable.

A big work boat is now a drift after falling off.

So it might have fixed itself.

The salvage crew getting airlifted in.

I suspect that's why they need an unlimited master on a salvage crew so they can take command and drive it to somewhere safer. ?

Quote (Waross)

An old tug-boat captain once told me of his impression of tug design.
Select the engine and prop that will do the job.
Add enough boat to keep them from sinking.

Something like this...Link

Like an iceberg, mostly underwater.
This type was popular at the mills and booming grounds on the west coast of Canada.

Taken at the Duncan Logging Museum , Canada.

There is a prop in the cage (not shown in the photo) that may be rotated 360 degrees continuously.
There is no rudder, the boat moves in the direction that the prop is pointed.
The fixed skeg at the back turns the boat in the direction the prop is pulling it.
That is why the rolling action when the boat changes direction.
I understand that some models were driven by a V8 diesel with over 300 HP.

"A master mariner is a licensed mariner who holds the highest grade of seafarer qualification; namely, an unlimited master's license. Such a license is labelled unlimited because it has no limits on the tonnage, power, or geographic location of the vessel that the holder of the license is allowed to serve upon. A master mariner would therefore be allowed to serve as the master of a merchant ship of any size, of any type, operating anywhere in the world,[1] and it reflects the highest level of professional qualification amongst mariners and deck officers."

I only know that because of pub piss taking between two holders. The Scottish none Great Lakes skipper put forward the point that the Canadian who was qualified should get the beers in because he was more senior. He claimed it was against his religion because he was French Canadian.

Could be... I'd never heard of a master mariner before this thread, or a Z-drive. You'd think that if he could pilot a boat anywhere in the world... the Great Lakes would be a walk in the park... same skills involved...

We have the equivalent in aircraft

Airline Transport pilot license ATPL.

But we have to be qualified on a type.

There are very rare pilots out there which are the equivalent to unlimited in regards they don't need rated on the aircraft. But they are restricted to none public transport and geographical area that the qualification was issued in. They are part of the test pilot certification setup so you don't often meet them. I have flown with one twice in 17 years.

The unlimited I have met seem to cover the full range of autocratic arsehole through to hairy bummed pirate.

But it's the same in the aviation world as well.

“Logic will get you from A to Z; imagination will get you everywhere.“

The special license for the great lakes makes some sense, just from physics. The water is fresh, so any ship will sit lower in the water than it would in brackish or salt water. This changes the dynamics of the ship's buoyancy. The great lakes are also known for some seriously rough weather. The largest tonnage transported in the great lakes for years was taconite. Ore carriers by design sit very low in the water, which when combined with heavy seas creates additional challenges for ship handling.

I suspect its a law exam addition. But didn't ask.

Someone thought the Great Lakes were saltwater?

My favorite Aunt (by marriage), her father was a Scottish sea Captain who, when he finally retired, was sailing the Great Lakes out of Sandusky, Ohio. And my boss, when I got my first job as an engineer, had been, before he went to engineering school, an able bodied seaman who worked the Great Lakes during the summer and the Gulf of Mexico during the winter. He was half Native American, a member of the Chippewa Nation in the UP of Michigan and back in the early 50's there weren't that many good jobs for young Indian boys so working the lakes was a good opportunity. He was eventually drafted due to the Korean War and while he could have gotten a deferment because being a able bodied seaman was an exempted occupation, he opted for the Army anyway as it allowed him to later go to engineering school on the GI Bill. He was a good boss, but the joke around the office was that he tended to swear like a sailor

That guy says Fitz rolled, dumped the cargo, but the Uni Wisconsin says the bow plunged into a wave and went down bow first.

I understood that the ship rolled and dumped its cargo after it was submerged.

Bill
--------------------
Ohm's law
Not just a good idea;
It's the LAW!

The UW report appears to contradict rolling. Rolling is a stability issue with large waves abeam and with a heavy water-laden load, they would not have capsized directly, whereas the wind and waves, apparently astern at the time, forced them down bow first. Once under, all stability in any degree of freedom is a moot point, however in an upside down and bow downward position, I doubt they would have had any inherent tendency to roll back upright on account of the hulls bouncy, no matter how they eventually hit the bottom, because the hull would have been flooded immediately by the water flowing in to replace the lost cargo. Upside down with a small amount of air providing little buoyancy and the weight of the rest of the ship below that center of action would not tend to upright the ship. It would probably just continue a nose dive to a more vertical attitude from which almost any final bottom position might result.

Getting back to Ever Given, here's how they really got her out.

A.

Looks like Egypt is playing 'hardball'...
"“The vessel will remain here until investigations are complete and compensation is paid,” Osama Rabie, chairman of the Suez Canal Authority, told state television in Egypt on Thursday. “We hope for a speedy agreement,” he said. “The minute they agree to compensation, the vessel will be allowed to move.”"

Can they put the money in trust and get the courts to free the vessel?

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

-Dik

yes I believe they can but Egypt will want the money now. If they do that it will be over 5 years possibly 10 before they get a look at it. Plus the court may substantially reduce the amount they will get.

They will also hold the crew until its all sorted as well not just the boat.

The boat itself is only worth 170 million. So actually they know fine that the amount they want is actually more than what they have impounded.

Arresting a ship has precedent under admiralty law.

I was thinking both items... It puts the action into the courts... I still have a little more confidence in them than I do in governments (just a little, in some countries the courts are as corrupt as the governments)... and frees the cargo and crew... else as you noted, could take years to sort out this issue.

Has the boat, legally, been seized?

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

-Dik

The problem is the $1Bn the Egyptians want is just plucked from thin air and wouldn't stand up in any court.

It is only those ships which gave up or took a view after setting sail and went round the Cape which they lost revenue on. A few 10's of millions. They shifted the back log in about 7-10 days at more ships per day so still got all the cash.
Don't know what the salvage team were on, but even if its Lloyds open book, this will be resolved via normal means. The rental on those puny excavators wouldn't be much...
SO their direct losses are probably <$50MM and maybe not even that. but now they've come out with a figure, they can't back down too far or they will "loose face". Only if a bunch of ship owners threatened to go the long route unless they freed the vessel on the grounds that any ship now stood the risk of being impounded in the event of an incident would they start to see sense.

The cargo owners are many and various so they have no single voice to speak up for them.
If I owned any of that stuff in the containers on the vessel I would be pressing the insurance company for total write off and re send it. It's going to be there for a long time....

Just hope not too many peoples personal possession were on it.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

I'm thinking of all the 'live' stock on board... I don't know how you get to them, unless they are the top containers... A big thing, I think the courts would look into is the pilot being Egyptian... althought they are protected from liability, the courts may view otherwise. There are some things that you cannot 'Contract out of'. In my earlier comment, I was wondering if the vessel was legally seized, or if the Egyptian government has just taken possession of it.

I've found no reports that the Ever Given was carrying livestock. In fact, from my searches, it appears that livestock are carried on specialized ships equipped for just this purpose. That being said, it was also reported that some 20 'livestock' ships had been delayed as a result of the canal blockage.

Unless some of the containers are refrigerated then the cargo is simply sitting there. Even the reefers as they seem to be known are fed from the ships power supply so whilst the contents might not be edible any more they at least won't rot.... The EG probably has enough fuel oil for months sitting there but might need a top up to get to its destination.

Container ships don't carry live cargo.

As to the legality of the impoundment, who knows? My guess is that it is being viewed as an extraordinary fee by the SCA and they probably have the rigth to prevent the ship leaving their jurisdiction until it is paid.

This is definitely one where possession is 100% of the law....

Nah this won't creat anything. There will be hundreds of ships and aircraft held like this at the moment today.

The last aircraft that I was flying that got impounded is still sitting where I parked it in ras al khaimah in the UAE. Hasn't moved in 11 years.

As long as it doesn't go like that impounded fertilizer. Interesting note, my dad works on agriculture and said the markings on their bags indicated that it was not fertilizer grade (too coarse).

Exactly good example how often these impounding of things happen tug.


Every one knows that it was for making explosives but they can't publicly say it with out proof.

I really hope none of those containers held immigrants.

If Egypt ends up owning the ship and the containers, they would have an interesting time inspecting each one- undoubtedly a few held illegal cargo. The shippers who could be traced that had shipped illegal cargo will probably lobby Egypt to buy back their container unopened.Perhaps the official in the catbird seat who decides the fate of the containers will see a healthy addition to his/her retirement fund.And the world spins around and around.

Although that starts me down a very regular thought process of why some humans have a natural talent for controlling machines which almost seems instinctive and others are monkeys on the controls.

The Dane comes from a family of seafarers his great granddad use to Captain square riggers doing the wheat run from Australia to the UK. His brother is a gifted pilot of aircraft. Both of them seem to struggle explaining why they do certain things.

Some of the best instructors and technical pilots that I have met are shall we say are rather rubbish at being the monkey on the stick, struggle with timing and job priorities. But they are utterly excellent at creating a good learning environment and supplying targeted information to others.

Once had a kid turn up at the flying school his dad had bought him 3 hours worth of flying lessons for his 15th birthday. Weather was crap low cloud so I couldn't take him off on a nav trip. So said sorry but really don't want to waste your money by taking you up. Only thing I would do with you today is doing circuits at the airport. kids face was a picture of joy at this prospect. Long story short after talking him round the first circuit and landing I basically sat with my hands on my lap and did absolutely nothing. He did everything including the coms with the tower. Spoke to his dad and said he was a natural. Last time I heard he was winning all the comps in the UK RAF for anything to do with ground attack and bombing. But was also well near the top for dog fighting as well.

Sort of leads me to think, if some people are naturals at some things? Is it possible the thing I am a natural at has not been invented?

Excellent video.

It certainly did some fairly funky manoeuvres prior to entering the canal.

Maybe the pilot or captain was so pleased with his ship drawing a phallus and some balls that he kind of took his eye off the large wall of sand on his right hand side....

They don't like to stop them because then they will just get blown around and drift. So they keep them moving so they still have rudder authority.

Given half the chance pilots regularly draw penises in the sky and controllers do the same when bored.

Must admit I am getting huge satisfaction with the internet thanks to this incident and thread.

Gone from my targeted news feed all the political crap with Scotland. I now every morning have a selection of Marine Transport interesting news, Some aviation and a load of stuff on smart homes and renewable energy.

I have complained about this with my wife. She gets in a funk because she likes to watch certain types of movies and TV shows that have lots of negative context (rape, murder, discrimination) and after a while Netflix Amazon and whatever only recommendation similar content. I have to come in and insert some diversity here and there. Honestly, we've been watching Benidorm and Friday Night Dinner and I can see her quality of life improving.

I love this forum because it keeps me always looking for new and interesting subjects.

Same here Tug and I am more than happy to admit its helped my mental health in these covid times.

My Mrs seems to be well into learning about bee keeping which has improved the recommendations on the family kindle account no end.

Must admit after this thread if there is a Suez canal big boat simulator I am going to give it a shot :D

Do you ever drive the boat? Our engineers get to fire them up and taxi them but obviously don't get to take them into the air. A couple have gone to the cadet school the company runs and now are flightdeck.

Some of ours are scared of flying and you will never get them up on a test flight.

Funny question. I have driven the boats (not near ships or rocks).I did manage to launch a microwave off a countertop. Our boats are 5000 horsepower and only 78 feet so they're quite responsive to control input. I didn't throttle back before going transverse with the z-drives and the boat stopped on a dime.

I'm also no good at throwing lines. I can hang a 2-ton chain hoist at full arm extension but can't throw a mooring line. I hate going out on the boats because someone always expects me to throw a line. I disappear to the engine room to monitor the engines during any mooring attempts.

I do get stuck on deliveries of new builds because I can solve problems that may arise. Taking a boat offshore once every few years is a recipe for sea sickness and I get it.

I can ride my boats whenever I want but I don't want to. Ships roll differently and I was able to tolerate that. Modern tugs are very stiff due to stability requirements and roll so rapidly you get rug burn on your nipples when you try to sleep through the sea sickness.

This is my last delivery. 100ftx40ft tug. 3 days before the weather improved. The trip was 4.

That would have me barfing as well.

Funny enough I never get air sick. But I do sometimes feel sick in the simulator.

That reminds me of getting the ferry to Shetland on the St Clair from Aberdeen as a kid.

I barfed on this ferry last time I went to Unist in Similar conditions. The locals to be honest used to struggle walking on flat land but were solid on a boat.

Another intersting twist... I suspect that Egypt has just 'bought the baby'. There may be no incentive to them unloading the white elephant.

Thems just lawyer's smoke words stomping up for potential clients. The Egyptian courts have not spoken and there is little evidence so far that Egypt is at fault. Egypt will not have $1B of leverage, should the cargo grow legs. And surely there would be advance fees applicable to salvaging the cargo, so as leverage would not be unduely lost. What transparent reason can they possibly come up with to force Egypt to relinquish their claim? ... waiting.

IKEA has around 110 containers on the boat, but they say that the impact on them not getting the gods are minimal.
They say they do not want to comment during the process.

So I guess they would not push for any unloading to get there gods delivered.
I think the cost would not be worth it since they still might need to pay there part in the general average settlement when it is finished.

I'm sure Egypt would want a proportion of the containers goods value for each and every one of them.

Going to become a very large write off is my feeling. Now the Egyptians have gone public on the windfall they see this ship being, they won't be able to accept anything less than $500 million.

It's going to be there years.

Someone explain to me how I, as a cargo owner, should be considered (even partially) responsible for costs associated with recovering said cargo? I paid the ship to get my stuff from 'A' to 'B', so unless something about the cargo itself prevented delivery (such as illegal goods, leakage of materials, etc.), I should reasonably expect said cargo to make it without further requirements. Granted, I may be out profit while cargo is being held or lost (which is where insurance kicks in), but is it seriously suggested the cargo owners will now have to pay more money just to get their cargo back?!

It's apparently a old maritime law.
It stems from that a ship would not sail anywhere without a cargo, and all shipment with ships where seen as a joint adventure.
So if the ship is bound to go under then captain could just dump the cargo to save the ship and crew or if it got stuck retrieving the ship and cargo or only the ship.

Before when everything was shipped with sailing ships and a journey could take month, I guess it might have been seen as resonable, but today in this situation I guess it feels a little strange.

One of the most know "accidents" containing "general average" as a component is (Gregson v Gilbert (1783) 3 Doug. KB 232)

The ship Zong that got lost at sea and to make there chances larger to get back to shore they threw the cargo overboard.

If the enslaved people died onshore, the Liverpool ship-owners would have had no redress from their insurers. Similarly, if the enslaved people died a "natural death" (as the contemporary term put it) at sea, then insurance could not be claimed.
If some enslaved people were thrown overboard in order to save the rest of the "cargo" or the ship, then a claim could be made under "general average".
(This principle holds that a captain who jettisons part of his cargo in order to save the rest can claim for the loss from his insurers.)
The ship's insurance covered the loss of enslaved people at £30 per person.

I personally knew a man who experienced a "Loss at Sea" claim about 20 years ago in Honduras.
The saga started when an Ex-pat was leaving Honduras and sold his pickup truck.
He was not paid for the truck and took it back.
Then he sold it to my acquaintance, Dick.
One day while parking the truck, Dick was approached by a man who said;
"That's my truck. I want it back."
The original purchaser had kept a copy of the registration papers.
Dick's lawyer told him;
"His papers are just as good as your papers. As an American in a Honduran court you will lose."
So far the other owner had no paper trail linking Dick to the truck.
He may have had a court order to seize the truck, but he would have to locate the truck.
Well Dick operated a fly-in fishing camp out in the Moskito coast.
That would be a good place to hide and use the truck.
He put the truck on a coastal freighter to ship it to the Moskito Coast.
The ship ran into a storm.
In order to lighten the deck load, the truck was pushed overboard.
The ship survived and made port.
Now the maritime law came into play.
Dick was informed that under the applicable laws, had the ship gone down, everyone would have shared the loss of their cargo, but if cargo was jettisoned and the ship survived the ships owners were responsible for the lost cargo.
The shipping company paid the claim without recourse to the courts.
It worked out well for Dick.

Hmm saw another article about him but I could not find it.

I do not think being there 4 years alone without electricity and other stuff half the time is the big problem.
It's not knowing when it's going to end that's the problem.

In Norwegian they have this fish farms in the middle of nowhere with bridges and a floating house in the middle of the fjord, all you have to do is feed the fish and see to that the cages are all right.
Maybe something for you cranky.

A leaner faster supply chain? Less clutter to unload.

Digressing a bit... the Ventusky app mentioned in an earlier post deserves added recommendation. It's incredible. You can set the elevation of the wind velocities to say 12,000m and catch the Jet Stream... and you can set it to about 30,000m and catch the wind 'coming back'. All with velocities... it also shows thunderstorms and lightning strikes and likely a bunch of stuff I haven't found yet.

What's magical about the Earth's wind system is that there is an altitude where the wind speed is basically zero, so certain types of balloons can "hover" over one spot for months at a time.

Thanks, I didn't know that... makes sense that if the a high velocity wind at one elevation and there's another one in the opposite direction at a higher elevation that there's a layer between where this would approach zero. Until looking at the app, I didn't know that there was a layer of high velocity wind in the opposite direction. I only knew of the jet stream.

They started learning about Jetstream's and the like when they Nuked Japan.

Concorde used to go completely different routes to everyone else because it was so much higher.

What I want to know is why when I need to get home early from work I always get a head wind going and then a head wind coming back?

BTW I wouldn't say its zero although it maybe horizontally compared to the main body of air moving. Its a shear zone and is quiet often like a washing machine. You will get a change in temp and then your in it and all hell lets loose.

From the site... with wind speeds of 150 km/hr...


Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

-Dik

That's only 80knts.

That's relatively mild. When it gets up over 120 knts that's when the cameras come out.

Given the location that's more the subtropical jet stream than the polar stream. Polar ones tend to be faster (and a bit lower altitude).

Quote (That's only 80knts.)

That's only at the locatio of the velocity shown, not in the 'red' area... the red area is 150km/hr or faster...

Every airline has a department dealing with this stuff and optimisation of flight routes.

It's a bit of a dark art. The weather guessers quite often get it wrong. And some of the flight planners seem to have a third sense which direction to send you.

Looking back up this thread I am seeing some things that don't fit the news reports for the Ever Given grounding incident. News indicates a sudden gust hitting the ship from the side, and visibility issues due to a dust storm. But the ship was headed directly into the wind. Allstair_Heaton reported the captain of the Maersk Denver had enough visibility to see the situation developing ahead and stop his ship. And additional seconds to get in an argument with the Egyptian pilot before taking control. These ships don't stop on a dime. So the captain must have had good visibility, and hence the additional time, to avoid a collision.

Any comments?

The wind pictures here seems to all be from the forecast, so they are not actually showing the the correct winds when it happened.

BR A

“Logic will get you from A to Z; imagination will get you everywhere.“

Yes

I wouldn't be surprised if they had radar transponders on them as well

In fact here is something about them

• https://files.engineering.com/getfile.aspx?folder=7712f926-f5c9-47f2-92a6-6

That having an argument with the pilot thing still brings up the responsibility question. If the captain is always in charge then he shouldn't have had to "wrestle" control from the pilot. If the pilot was in charge on that ship and needed control taken away, then the pilot would have been in charge on the Ever Given which makes the crash their fault.

Its happens in all multi crew control situations with command.

We have the same thing multiple times a day while flying. Air traffic control, marshalling of aircraft on the ground, technicians and technical issues, operations etc.

The Captain has ultimate authority and responsibility but 99.9% of the time you follow what you have been requested to do. But occasionally you have to put your foot down and say NO. And then when someone try's to bully you then you assert your command.

Its a very personal skill set and to be honest you can't teach airline Captains to have this leader quality. There are also cultural differences come into play. It takes about 6-12 months for people to grow into the role. Some fail and unfortunately have to go back to being a follower.

I will admit 16 years ago now when I was doing my command course I had a pushy air traffic controller trying to push us into a situation which would have solved his problem with another aircraft but would have taken away my escape options. I refused he got stroppy and it was instinctive to shut him down and assert my command. That 5 seconds after you say something did make me pause but then you have the rest of the flight to complete. Debrief was short and sweet. Good call, nicely dealt with, he wasn't happy but tough you are the Captain I think we can sign the command responsibilities and asserting's them section off.

I am pretty certain its the same in maritime after doing crew swaps with supply boats for the Northsea. Some Captains were the micro managers and others were more relaxed but you knew if problems occurred there was one boss.

I suspect the bloke that told the pilot to sex and travel is similar to myself. Comes from northern latitude stock, started life in heavy industry with rough men to manage and has a instinctive reaction when his third sense alarm bell is triggered.

I also suspect similar to myself we are best kept away from the office admin staff and office politics because it really upsets things when our bull in a china shop method of conflict resolution comes into play. But such is life bosses are happy that the job gets done safely and economically, our crews are happy because they have a boss that doesn't take any shit and protects them.

I like nothing better after working a week down route when the most junior usually young lady onboard feels comfortable enough to tease me in the crew bus because say my uniform is showing a weeks worth of wear and I could do with a clean tie. "hey Alistair are you going to make soup with that tie when you get home?" I think it means that I have managed to promote communications in my team with even the most junior feeling they are empowered to speak to me. Which I believe is crucial for flight safety. I know some crew its only the number 1 cabin crew who speaks to the Captain. I would hate to work in that environment. In fact if it was normal in a company I would be looking for another job pretty quickly.

In case the above sounds a bit to aggressive, the skill I told new commanders was the most important was the ability to listen even if what you were listening to was bollocks. But there are times which are relatively rare when you have to shut the person speaking down and assert command.

Suez Canal starts work to extend double lane after Ever Given grounding

Egypts claim is reduced form 900m to 600 m dollars.
Ever Given insurers say Egypt's $600 million claim is still too much, as authorities continue to impound the ship

It continues...

"An appeals chamber at Ismailia Economic Court held hearings on Saturday over the ship's detention, which the SCA is seeking to uphold following an appeal by the owner, as well as the SCA's financial claim.

Lawyers representing Shoei Kisen argued that the SCA had been at fault for allowing the ship to enter the waterway amid bad weather, Ahmed Abu Ali, a member of the legal team, told Reuters, adding that the authority failed to prove any fault by the ship.

Recordings from the ship that were presented to the court showed disagreements between SCA pilots and its control centre over whether it should enter the canal, Abu Ali said."

Seems they are willing to release it for a 200 million deposit

There is a reason Egypt wanted the black boxes before the rest of the world got to hear them.

Think of the insurance arrangements. The containers are insured by the individual snipping agents. Many insurance companies will share the burden of the cost. The next major expense is the hull of the ship. That isn't worth $100 million let alone 600 or 900 million. It's likely the ship has been written off at this point. All Egypt is doing is increasing the insurance rates to transit the canal. I feel this is going to have a very negative impact on Europe as their commodity prices are going to rise as a result. Egypt is only hurting themselves at this moment.

New court date of 20th June... https://splash247.com/ever-given-compensation-batt...

https://www.wsj.com/articles/egyptian-officials-ac...

I like the last one "“We first estimated the value of the ship’s cargo at $3 billion. Our share of that value was established at $912 million for the above mentioned costs. When the shipowners got back to us saying the value of the cargo was $750 million, we lowered our demand,” said Mr. Sheisha."
So an average of $70,000 per 40ft container sounds about right.

They start at $900M based on $3Bn

Now it's "only" $750 million they still want $700 million??
