Dramatic Bridge Collapse in Maryland . - Casualties reported.

The two Pilots and the Master of the vessel are in deep $hit for this... they will be looking at serious jail time. The vessel looks under power as there is smoke coming out the stack (the big plume of smoke seconds before it hit suggests they went full astern very late) The lights being out on the vessel is a SOP for entering and leaving port to increase visibility for the crew.

looking at the AIS she was straight on in the channel and lining up so its either a steering failure and drifted into the bridge or a complete breakdown of coms/observations/situ awareness.

What is amazing me is that she doesn't appear to have any tugs on her for such a large vessel and such a tight Bridge... from experience I would have expected at least 2 tugs (more likely 4)

I am not seeing much evidence of High Winds from either the footage or the aftermath interviews and the visibility is excellent so cant see the weather being a factor

My thought are with all concerned parties

Deck lights were on up to the point of impact, it’s over 50m so the Col regs require this.

See the video above your post. Full blackout by the looks of things.

Looks like blackout followed by auto recovery, then blackout again. Most likely issues with either electrical components or software. Probably a combination of both. I wouldn’t rule out a fire someone on the ship either.
 
looking at that pic if the Bridge hadnt stopped it then it would have hit that pylon... chances are it would have sank
 
6 People missing according to the news a little while ago.

That is going to take absolutely ages to clear up.

Getting the remnants of the bridge off the ship is not going to be easy. Some shipping lines used to store the dangerous goods at the front of the vessel, so you can't just go in there with a load of hot cutting equipment and start hacking away at it, especially as it is in the vicinity of stacks of containers at all sorts of weird angles potentially damaged and holding goodness knows what dangerous or flammable goods.

And the port itself will be out of action until this is sorted. Which will take a very long time.

I would not want to be the public liability insurer of the ship.

you're talking Billions in this... look at the Deepwater Horizon and the knock on costs they got hit for

First concern is for those missing, but once the recovery operation begins you’re right it is going to be a mess to sort out.

The shipping company will likely be dragging in the company responsible for software management, as it’s possible that is the issue here. A ship going black is almost always an issue with software.

Confirms a power blackout, which is stating the obvious given the footage available.

I don’t think it ever recovers full power. It has a black out, emergency generators / black start generator activates, probably along with the diesel fire pumps. Lights could come on from UPS emergency batteries. At this stage i’d say the thrusters and propellers didn’t have power and the ship just went with the flow.

Could be that, but I reckon it’s more likely to be blackout followed by auto recovery, which prioritises propulsion and steering. For power to go again seems there has been another fault that has triggered cause and effect and the power has gone again.

Depending on the DP classification emergency generator is manually activated as the auto recovery is considered redundancy.
 
Info coming out that the vessel had issue in port with power interruptions…. Should never been allowed to sail if that’s the case 😡

No DP on a container ship. And no similar type of 100% redundancy on the Dali, it only has one main engine and propeller as far as I can see.

Jonny’s scenario most likely then. Especially if power issues in port is correct. A ship that size hitting the bridge at 7 knots is frightening. The forces will be massive.

All the FPSOs i’ve been on, from a black start it’ll be be a good 20-30 mins to get the main systems back on, swb breakers on in sequence as per procedure etc the thrusters will be HV driven so it would need transformers and bus bars racking in. Not a 5 min job.

That’s my experience too. Takes the technical lads a while to get systems back up and running.
