Baltimore bridge.

The bridge in real time:


As already observed, power goes out for a minute or so. When it comes back on the engine looks to be going flat out (black smoke). Either full astern to try and stop, or ramming speed if it's a terrorism thing. The fact that the ship seems to change course to move straight towards the pillar seems a bit sus to me. I can't see it going off course so much for that short power outage. Unless of course something was wring before that and the power outage was an attempt to fix it.

Boats can skew around when their props go astern, if its a single prop ..... but this much, so fast on something so big?
 
…..aside from the tragedy of lost life, given the standing of Baltimore I suspect this will have a significant impact on the economy.

Time will tell of the causes but I remember reading some years ago that civil engineering standards and safeguards in the US are somewhat third world. It was always something that stuck with me, that bridge seems to fold like a deck of cards.

We'll find out in due course, but you can't go by smoke from the funnel. Modern ships don't produce much smoke even if you ram the engine from full ahead to full astern, it will be variable pitch propellor(s), and the engine speed will be computer controlled so as not to produce smoke like that. I would say it's an indication of a serious engine problem.

Oil rigs are designed to us standards in the UK and quite a number are more than 2x their design life. Its not an issue of the design standards, any bridge of this design would fold like a pack of cards if the pier was taken out. Unfortunately a single point of failure issue. The plinth will be designed or inherently capable of resisting some level of lateral impact but most likely not a fully decked cargo ship.

….fascinating stuff, thanks for the insight. I think the item I saw/read was referring to motorway bridges, it did surprise me at the time..

I have read that there is concern about motorway bridges on the interstate highway system. Deterioration due to ineffective maintenance.

IF its a modern ship!
