Electric car ship fire.

Cargo Ship Carrying 3,000 Vehicles Abandoned After Fire Breaks Out Near Alaska

The fire is in the vicinity of the engine room. I'll give the electric cars the benefit of doubt for now. The small white dot to the right of the arrow is likely the engine room forward bulkhead. The other white dot to the left is a cargo hold bulkhead but the double bottom fuel tanks likely sit between the two bulkheads.

According to Zodiac Maritime, the London-based company managing the ship, smoke was first seen coming from the stern area where electric vehicles were stored.

A fire safety director from the International Association of Fire Fighters said the way the CO₂ system failed to stop the blaze suggests the fire likely started from an electric vehicle battery.

Interesting that you chose to crop your picture to essentially not show where all the smoke was coming from

 

[TugboatEng]

We had all seen where the smoke was coming from. I thought my markup looked tacky so I didn't use it. Maybe the bulkhead markings weren't as obvious as I thought. Anyways, the engine room occupies the red box and the fuel is in the blue box.

It might have got to the point that special electric vehicle and battery transport cargo ships are required.

With a method that can deal with battery fires

 

[TugboatEng]

Maybe we need to treat electric cars like wine and age them for 6 months before selling them to the consumer. You know, get them a little more right in the bathtub curve.

There's nothing the literature that suggests lithium batteries have an infant mortality mechanism that results in thermal runaway, aside from latent manufacturing defects

 

[TugboatEng]

Yes, latent manufacturing defects are a leading cause of infant mortality.

 

[IRstuff]

Infant mortality has a significantly higher failure rate, which is not supported in the case of these batteries.

 

[Alistair_Heaton]

Wonder what testing the batteries are subjected to and at what stage in the production cycle of a car.

 

[TugboatEng]

I doubt the batteries have been through a single charge cycle before these cars end up on the ship.

Maybe you just haven't seen the evidence. (I haven't either on "these batteries" I don't even know what "these batterie ARE.)

But in the case of most manufacture item, especially complex ones with many components, the likelihood of failure in their infant life is much higher than that in the adolescent and young adult ages of the item. And lithium ion batteries that power electric vehicles are certainly what I would describe as complex manufactured items.

For example spinnging hard disk drives:

Haven't seen any, because there's nothing published at all

 

[GregLocock]

OK this isn't infant mortality, but here's an attempt to look at the the 500 cycle failure rate, note that out of a relatively small sample (~25) 4 are at 60% of their cycle 80 capacity, which means they are entirely reliant on the battery pack monitoring system to avoid overcharging in a large pack

I've never seen an r^2 of 0.1 being used for anything! It's a good thing he's got that failure at bottom left otherwise he'd have a gradient of 0.

The cars will have had some charge in order to be loaded, like they put in about 3 litres of petrol just to drive them on and off the vessel.

This looks like a typical car carries so the vehicle decks extend the full length of the vessel.

There are reports that the fire was detected on a vehicle deck and despite fire fighting they couldn't put it out and have abandoned ship.

 

[Alistair_Heaton]

Seems it's still floating.

Salvage team still en route

Fire forces cargo ship full of EVs to be abandoned in Pacific Ocean

A cargo ship carrying nearly 3,000 vehicles, including electric models, remains adrift off Alaska after a fire forced the crew to evacuate. Salvage teams are en route to assess the vessel.
