Crash of cargo ship into Gwangan Bridge in South Korean

RE: Crash of cargo ship into Gwangan Bridge in South Korean

Amazing how clueless the drivers are. Some finally slowed down.

Yes - I noticed that some slowed and saw what was coming and then zoomed ahead to get over the "collapse area".
There's some brave souls in Korea I guess.

But if things fell the boat would hold the girders up off the water I suppose!!!

RE: Crash of cargo ship into Gwangan Bridge in South Korean

Amazing to watch the traffic on the bridge not even slowing down. And you have to wonder exactly where the ship was headed. I mean it's obvious it was not in the channel and while you can see that they were in full reverse, they must have been moving along pretty quick if they were not able to stop in the distance that they had. I guess it could have been a failure in the steering mechanism.

RE: Crash of cargo ship into Gwangan Bridge in South Korean

Wow, the ship itself didn't even notice until they were about 2 ship lengths from the road; obviously, it takes more than 2 ship lengths to stop, unless you hit something winky smile

RE: Crash of cargo ship into Gwangan Bridge in South Korean

I was right, IT WAS a "failure of the steering mechanism". In this case, the 'nut' holding the wheel.

RE: Crash of cargo ship into Gwangan Bridge in South Korean

It looks like it was leaning left all the way from port...

TBH I think they did a pretty good job slowing it down - they very nearly made it - the superstructure which collapsed was pretty flimsy - If one of those cranes had hit the bridge it would have been a lot different alright or if the bow hadn't just made it under the deck.

I like the way they thought they could just sail off into the sunset though

RE: Crash of cargo ship into Gwangan Bridge in South Korean

I don't think they put the brakes on until the little guy rushes back toward the bridge at 0:07.

Edit: ...and another guy running across the deck almost gets swatted with the mast at 0:35.

Edit Edit: The ship stops in less than half a length with a little help from the impact. It looks like it is unloaded based on the green line above the waterline.

RE: Crash of cargo ship into Gwangan Bridge in South Korean

Officials are also looking into why the vessel, Seagrand was in the waters near the £500 billion Gwangan Bridge - South Korea's second longest - when it should have been heading in the opposite direction.

According to the KCG, the Seagrand arrived in Busan around 9am on Wednesday morning to unload 1,495 tons of iron pipes.

According to local news agency Yonhap the Seagrand also hit a moored cruise ship just 40 minutes before the accident.

RE: Crash of cargo ship into Gwangan Bridge in South Korean

As best I can tell from the video and IRstuffs link, the ship strikes about where I show.

RE: Crash of cargo ship into Gwangan Bridge in South Korean

Agreed, Charlie... pretty surprised they were able to make that much steam and at that angle towards the bridge. They must have started right where that other ship is moored above Diamond Bay and put the pedal to the metal. Anyone want to take bets the cruise ship they hit was moored in that same location?

I am thinking some sort of "grand standing" show to the patrons and staff of a local establishment he frequented while on shore. "Watch as I swing by and blow the horn, Honey"

RE: Crash of cargo ship into Gwangan Bridge in South Korean

I think it is more likely that it was where the cargo ship was just above where it says view point and was tying to do a 200 degree turn to the right but at high speed.

RE: Crash of cargo ship into Gwangan Bridge in South Korean

I think if you look closely, the wake indicates that the ship was in reverse from the start of that particular video, as indicated by the churn in the wake on the sides of the stern.

RE: Crash of cargo ship into Gwangan Bridge in South Korean

I've been searching with no luck to see if any saved the tracking of the ship as it left port to the bridge.

I have found where the ship was taking back to the scene of the crime for a few days, then taken out to sea to be anchored

That looks like a steel yard which would match the story regarding their cargo.

I think you are right. They were already at, say, 1/4 throttle in reverse given the short run-up and the obvious need to turn around. Then at 0:07 they go full throttle when they realize they won't stop short of the bridge. You can see that the length of the churn almost triples starting at 0:07.

Just another day at the lake.

RE: Crash of cargo ship into Gwangan Bridge in South Korean

I wonder why they didn't turn as they had the time once they were in reverse.

RE: Crash of cargo ship into Gwangan Bridge in South Korean

I don't think that the rudder is that effective under those conditions. ie: coasting forward with engines astern.
On the other hand, bow thrusters will allow them to both turn and brake. I guess that they didn't have bow thrusters. grin

RE: Crash of cargo ship into Gwangan Bridge in South Korean

There is a brief view of Yongho Pier in this older amateur video which the ship was pulling away from and where it subsequently hit the yacht according to this story. You can see the approach spans in the background where it struck.

Edit:
A view across the incident area from another of the same users videos.



And here is a video showing the real time tracking of the ships in the bay at the time of the incident. It was linked on the ship tracking page @byrdj posted.

Wonder what the name of the ship's pilot is? Maybe we should ask KTVU San Fran. I hear they have sources for pilot names. smile

What is that little blue triangle on the video? A small boat or a tug?

Captain of Russian cargo ship that crashed into Busan's Gwangan Bridge taken into custody
https://www.youtube.com/watch?v=DEXg3k9p7A4

A 6,000-ton Russian cargo ship that crashed into a bilevel bridge in the South Korean port city of Busan last Thursday was in communication with local marine traffic control, according to the city's maritime police.

The latest findings indicate the captain, or possibly other crewmembers of the Seagrand vessel, were in contact with traffic control, contradicting earlier claims the captain of the ship could not respond to radio signals because he did not speak English.

The captain of the ship was also drunk at the time of the crash, according to local news service Newsis.

Busan maritime police said Monday the Russian vessel was in correspondence with traffic control before and after the crash.

When the ship was asked whether it was leaving Yongho Pier it replied "yes," and asked for a tugboat. The Seagrand then confirmed it had collided with the Midas Yacht, and would be returning to port. But minutes later, the ship denied the collision and asks for two tugboats to tow it out to sea.

Communication was subsequently lost, during which time the Seagrand crashed into the bi-level Gwangan Bridge.

Seven minutes after the crash, the ship again reached out to traffic control, reporting it would be dangerous to anchor the vessel.

The captain was intoxicated while steering the ship, according to reports.

It looks like the KCG vessel. It shows up after the first impact with the yacht, then circles the Seagrand frantically, and then follows the SeaGrand out to a mooring location after the second incident.

Cute, Keith, but the article SUI (steering under the influence) allegations were already apparent the day of the accident, as shown in the article that was linked.

It appears he caught the end of a dock and twisted it around. Then he must have stopped long enough for one of the sailboats to move out of the way because the video skips and then it's gone from the picture.

RE: Crash of cargo ship into Gwangan Bridge in South Korean

Here is a longer "Dash Cam" video with the bridge crash.
