Shocking accident. lt's claimed the container ship lost power and couldn't steer. Slightly unusual route out of port.
Minor course change shortly before the bridge strike.  Click image to enlarge |

Apparently we get a lot of our imported gas from there................so expect that to go up again.

being at sea myself right now, i can upload the charts if anyone is interested,
Its tampa bay all over again. luckily this time they got the traffic stopped. Cargo ships don't have UPS to the steering, so once they lost power, they are along for the ride. they have a emergency gen which will power it but by the time someone gets it going etc its too late. Normally we will have ~20 seconds before our em gens are online and providing load to the net. Even my boat, 2021 build $1.3billion cruise ship only has UPS to one of our 3 steering pods and it only powers 3 out of the 4 steering motors for 60 seconds (60 seconds of moving the pod) - Well that's the requirement anyway, we've tested it for longer you just keep restarting till it fails we think we have 3-5 mins. |

I am originally from MD. Crossed the Key Bridge regularly - but quite a while ago. Scary.
@Likeomg that sounds really scary. Granted, large ships don't travel at really high speeds, but this accident and others (Exxon Valdez comes to mind - error, not tech failure I know, but still) show what a few minutes of traveling in the wrong direction can do... Would UPS to critical systems really add that much cost?
RRC 2Dr, RRC 4Dr, P38, and 2 L322s, 2 FL1s and a L663 on the way |

Pretty much everything is powered on the emergency gens which are usually online in sub 20 seconds, a pair of v12’s producing 2 megawatts each (no propulsion tho)
Again my ship is setup totally different to your standard container ship, we have 2 separate engine rooms, 6 diesel generators with 2 separate switch boards + emergency switchboard The battery supply is only to take the load while the emergency gens get up to speed I’m a little surprised we don’t have ups on all 3 pods, if we trip the power they just lock in position so you could have two pods hard over while the other (ups pod) is trying to steer… the only option is to brake release them and let them go all floppy but who knows what rate of turn we would have in this situation… |
