Disaster "Mass casualty incident" declared after Key Bridge in Baltimore collapses

No article yet as this just happened, but could be big. One of the largest bridges in the world according to Wikipedia.

Damn, and I had just only watched a video of the Sunshine Skyway bridge collapse mere weeks ago. This played out almost the same way, but the whole damn bridge fell versus only a section of the span.

My heart goes out to those who were crossing the bridge as that happened. We should only be lucky it happened in the pre-dawn hours and not during the peak of a commute rush.
 
Mildly educated opinion on this.

I've watched the video like 20 times. Ship loses the plant. Looks like the vessel is lined up to pass under the center span of the bridge before loss of power. Thirty seconds after power loss either plant is restored or the EDG finally trips. Vessel goes full astern (black exhaust out the stack means she's really pushing it) and the ship begins turning to the right.

Why? Because a standard propeller backs to the left, turning the bow to starboard.

If I were making a guess, I'd say the accident was caused not just by a loss of power but also likely a poor response from the conning officer. While I like "oh shit dump it" commands as much as the next guy, I think this was probably the cause of the vessel veering and ultimately the allision.
I suspect that he tried to put the backing bell on because, in his mind, it was the only way to avert the allision. There was no way they were going to shave off speed or avert the allision head on and swerve it, but either they didn't have rudder control, the helmsman wasn't up to the task, or it was just too late. I'm not really sure, from just what data we have now, what the Conn could've done.
Thanks. Sorry shipping is not a world I’m familiar with whether merchant or naval.
Another question? Are the control systems hard wired or capable of being damaged remotely? Like the airliners that can fly by wire?
Not that I know of. These are pretty intricate pieces of equipment and a lot of them still run on analog systems.
 
Like I said I'm unfamiliar with merchant ship regulations or if they have audio-visual recording devices, but from my experience I imagine not. The Navy didn't. There will be telemetry data and all the deck logs of orders passed, engine conditions, etc during the transit both in the engine room and the pilot house. It won't get actually what was spoken but it'll cover every order passed and what they'll do is compare that data that's on the logs with what shows up on the recorded telemetry.
This ship should have a VDR (vessel data recorder). All STCW ships are required to have them on board. I very much doubt it's content will be released to the public however.

Does it collect audio-visual or is it telemetry data like speed, course, echosounder, and that sort of thing? I imagine it has to record VHF, though.

The most screwed-up part is that the actual causalities will be sidelined as a plethora of the usual tragedy "vultures" begin circling the aftermath to start using the event to make the whole thing about themselves or whatever retarded cause they think will get an opportunistic boost from this.
I mean, you’ve pretty much described the state of American politics in 2024. Never mind that a bridge has collapsed, people are dead, and the consequences of bad public policy at the state and federal level will make it nearly impossible to replace it.

No, how does this situation affect MY group directly! It’s a shame really, but most US infrastructure is not in a great state of repair, but too expensive to replace because of aforementioned bad public policy.
 
Took 5 years to build this bridge in the 70s. How long will it take to rebuild it?

It also cost $60.3 million dollars to build it ($308,789,732.67 when adjusted for inflation)
How much will it cost to rebuild it?

The Bourne and Sagamore Bridges are around 620 feet long each. They are about 90 years old and need to be replaced. They have been talking about replacing them for years.

Latest estimate to replace both bridges is 4 billion.

Yes, they will have the past 24 hours of audio from on the bridge. I believe some vessels have video as well although I'm not sure if that's required. All propulsion and rudder commands should also have a record.

Edit: By record I mean propulsion and rudder data is automatically recorded and held.

Interesting, and it should be very interesting for when the investigation starts digging here. I still hold that most of the "responsibility" for this lies with the probable willful ignorance and dismissal of whatever problem they had with the power. I very much doubt that this was the first time they had an engineering casualty.
 
To people wondering why some reports have the ship sunk, when in reality <look at picture> there are always inaccurate reports in these situations. Shit, I almost posted that the ship had sunk after reading it at multiple sources, but decided to check the port of baltimore livestream, and the ship is right there in frame.

This is actually a huge deal. It's not "just a bridge" its a major bridge on the Eastern Seaboard that will take like 10 years to replace with things how they are today.

Baltimore could face $1.8B budget deficit over 10 years, finance officials project

“That’s a scary picture,” Council President Nick Mosby said, looking at a chart depicting how the projected deficit could balloon between now and 2034. The compounding budget problems would mean starting each fiscal year over the next decade with an average shortfall of $175 million, the chart noted. That amounts to about 4% of the $4.4 billion budget Baltimore passed this fiscal year.
the city’s expenses are growing nearly three times as fast as its revenues.

Does that include any kind of video / audio recording of the bridge, and engine room or is it just telemetry type stuff? I guess I’m just wondering what kind of timeline they will be able to put together when they investigate.
An Oceanbulk vessel was the Bureau Veritas testbed for different types of remote inspection technologies and techniques (RIT) as BV, Oceanbulk and Glafcos take the lead in using robotic solutions for ship inspections

Bureau Veritas (BV), a world leader in testing, inspection, and certification (TIC) has directed and supervised the testing, establishing ‘proof of concept’ and operational purpose, for remote inspection technologies and techniques, including an aerial drone, a miniature remotely operated vehicle (ROV) and magnetic crawlers, on an Oceanbulk double-skin supramax bulk carrier, built in 2008 and classed by BV.
Dunno if this is applicable, just something I ran across earlier when doing cursory searches for the firms name.

Baltimore bridge collapse live updates: Ship lost propulsion, warned of collision, officials say​


set & drift analysis suggests loss of main steerage and power while making 13 knots in a crosswind.

From the live stream overnight. As the ship came into view, it had all its lights on..

A moment later after this still all the lights on the ship go out...
1711453674920.png


It drifts for aabout a minute, then the lights all suddenly come back on..

There is a plume of smoke from the stacks as the engines fire back up to life..

Only for the lights to go back out again just before impact.

I imagine it was 5 minutes of sheer terror trying to restore power and regain control of the out of control ship... but it was too late.

I hope i see this in the BrickImmortar video....

Video of the ship lights going on and off. The ship had no power. The pilot likely did all they could do...
