Think it’s probably more appropriate to say recover instead of rescue by this point. Unfortunately the Atlantic is pretty cold this time of year.

And they plunged almost 190 ft (Wikipedia info) into said water.

So they’d free fall for ~3.4 seconds and hit water at around 75mph. That part could be survivable depending on angle of impact and safety features of the car. Assuming they survive impact, getting out in the dark with cold murky water coming in car and surviving the hypothermia as well and odds are slim to none.

Minor correction, that’s not the Atlantic, it’s the Patapsco river which flows into the Chesapeake Bay.

Still cold as shit and very likely those people are dead now unfortunately.

There’s an outside possibility of revival if the water is cold enough and they’re found soon.

So cars these days have anti-collision systems. One would think a million dollar boat, with millions of dollars in cargo, approaching a multimillion dollar bridge would have some sort of active sensing system to prevent a collision. That video shows the Dali strolling right into the support. It wasn’t a glancing blow, rather it was a direct hit. Either somebody f’d up big time, or major act of sabotage on US territory.

Apparently, the Dali lost all power. Anti collision kind of needs power to work, so having it would not matter regardless

As an electrical engineer I will say there are giant thick sections of code for backup power regarding life safety systems. Generally a backup generator will keep running even if on fire and breaking just to keep power on… backup batteries on even more sensitive equipment provides even more redundancy. Power failure leading to a disaster is a engineering failure.

My first thought was similar, there’s clearly a lack of redundency in a space that should have had more consideing an entire bridge just came down.

At the same time, apparently the distress call went out moments before. A ship that size is not going to be able to turn in time, and a ship that weight is going to impart a hell of a lot of force even if moving slowly.

Someone very well may have fucked up, I would say the chances are pretty high, but I feel like that happened well before the power went out

Lost power as in no longer able to control its direction and speed.

Even if backup power is still feeding your detection system, all it can do is tell you what you can already see in front of you: your gonna hit that bridge. Still nothing you can do about it.

I wouldn’t think anti-collision systems would be feasible on a container ship: they’re too big with too much inertia. It can take miles to slow to a stop or execute a turn. It’s not like a car, where you can just hit the brakes and have immediate results. All that extra braking and re-accelarating would burn a bunch more fuel, too.

Don’t need binoculars. As the ship drifted out of control, they had a clear view of the bridge they had no power to avoid.

If it takes miles to slow to a stop or execute a turn, that just makes me think the ship’s future position is easier to know with certainty, giving any collision detection system more lead time to alert to expected collision.

To alert to, sure. It makes car-like automatic braking infeasible though, unless we’re looking exclusively at stationary objects like bridges, which are only present for a miniscule fraction of a container ship’s travels; they won’t have time to react when a sailboat suddenly tacks across your bow, for example. And it certainly won’t help when the ship is without power and drifting, like the one that hit the Key bridge.

Best guess atm is they lost power when approaching the bridge, they, at least periodically got it back, but given that they had lost power they were taking measures to stop themselves. They put their engine in reverse and dropped their anchor. Both of these cause the ship to go off course as they slowed it down pulling it out of the center lane it was in. Basically the crew panicked when trying to do the right thing and did everything wrong.

A ship that size takes a loooong time to stop. There are no brakes. It has momentum and will keep moving forward, even without propulsion, even with the engine in full astern mode.

I think that’s when it was built. A superstructure like a major port bridge will be well into the billions in 2024 money.

Remember to also factor in losses due to transport disruptions in the calculations regarding the value of the accident

The bridge is basically valueless compared to everything else about the ship and cargo plus the lawsuits from various contract breaches and other damages. Port shutdowns, environmental cleanup, insurance losses. $100m is a rounding error.

It was worth $110M in 1977. Probably a couple $Billion now.

Not sure what you’re trying to say. The new bridge will cost far more than the old one, and the insurance settlement for the loss of the bridge will far exceed the original construction cost.

I suppose there’s a difference between the resale (or original) value of the material, and the abstract value of having an, any, bridge in that location.

That isn’t how damages work either. They can’t reuse anything so it’s the price of what it costs to rebuild the same bridge in the same place with current prices and the estimated cost of cleanup and whatever business damages are claimed which almost certainly exceed the cost of the bridge.

If you lose control driving and knock over an old tree and out lands on my house, you’re not only responsible for the tree - you owe me a house.

The economic damage of destroying a bridge that’ll take years to replace plus blocking a major port until debris can be cleared is going to be at least 10-figures - probably more.

It’s cost is both material and in the business of links from one side to the other. It’s almost certainly worth multi billions at this point.

And not just the business from one side of the land to the other, but also from the port to… everywhere out in the ocean. With the old bridge remnants blocking ships, that’s a LOT of lost business…
