Quoted: I'm no marine engineer but have significant experience working with vessel steering systems on the control end. The way it works is vessels of this size typically have two large hydraulic steering pumps that are running at all times. At the steering stand or bridge console pump 1 or 2 can be selected very quickly. The pumps themselves should be powered by either a primary bus or emergency bus. Which bus is feeding the pumps depends on the state of the ship's DGs but it is pretty rare for all of these systems to fail. What I predict probably happened was a failure of one of the transfer breakers shortly after departure as the engineers may have switched from a smaller auxiliary generator (which may be used in port due to smaller demand) to one of the larger primary DGs. Typically two DGs will be running at any given point in time with only one actively providing power to main buses, and all that has to happen from a mechanical failure is for the transfer breaker to switch which DG is handling the load to the DG currently on standby. The failure occurred faster than the emergency DG could be brought up and supply transferred to the emergency bus. Does it happen often? No. But it does happen. It happened at the worst possible time for this ship. A steering stand failure could be a possibility as well, but a failure at the stand is not that common. In any case, the ship is sinking so this information will have to be collected from the VDR capsule. The VDR will log a significant amount of events but unfortunately it will likely not log automation system alarm history (showing what plant failures may have occurred) but will log things such as rudder angle - not all that useful as we know the rudder angle was not so good. Some automation systems have their own separate VDR (not all that commonly used in my experience) or report events real time over the vessel internet connection. We'll have to wait and see. Most of the automation systems out of various smaller Asian countries suck in this regard. Expect that here on out a tug escort will be deemed required for all vessels departing Baltimore until they have cleared the (soon to be new) bridge. View Quote I started to type out a reasonable explanation very similar to this as I am also intimately familiar with ship steering and propulsion systems. But then I realized how unamerican it was for me to not instantly jump to the remote hacking conclusion that one of our experts has already put forth. I guess you and I are voting D from now on. |

Quoted: And it was made in 1972 before there were ships with this kind of tonnage. In 1972 the largest container ship was the LiverPool Bay 2961 TEU. The Dali was 9900 TEU. So over 3 times the cargo capacity and probably 3 times the size and weight. I doubt those concrete bollards produced in 1972 had that size of a ship ( which is a medium size ship today ) in mind during the design and construction.

Going to one screw and one propulsion plant saved cash, but wasn't great for redundancy, e.g., Amoco Cadiz etc. |

I’m guessing by the black smoke, the ship nuked its engine.
Oil fed into the cylinders - probably from the turbo bank(s) - it ran away. They killed it to try to stop the run away. Went to fire it back up, it ran away again (black smoke). Rinse repeat. Or the fuel pump let lose and started to dump fuel. That ship has scrubbers on it. No way it should smoke like that. |

Quoted: A week after "someone that has a history of being handed Libyan weapons while destabilizing Syria to the benefit of France and the US" attacks Russia? No. It is completely impossible that any foreign state actor could hack a satellite feed and commandeer the 100% computer controlled guidance and propulsion systems of a ship and ram it into a bridge. That would be just as insane of a statement as saying that the same foreign state actor could or would turn off millions of cell phones across multiple systems, companies, and networks as a cyberattack warning.

In the video I posted above, it says that the crew dropped anchor on one side, (presumably as an emergency response to stop the ship?). Too late for intended effect I guess.
Maybe they didn't have power to do it before the lights came back on? Doesn't seem like these guys were on a kamikaze mission. |

If they had full tanks. And it depends on the compressors they have on board as well. 3 or 4. We also don’t exactly know when it lost power. I’m assuming at some point post tug release. In the video we see zero smoke at first as it comes into view of the camera. But reality - we don’t know if it’s under its own power or not there. Just because the lights are on, doesn’t mean anyone is home. They could have been waiting for generators to build up air. Fired the engine again, black smoke from the run away, or possibly lack of engine start up. Rinse. Repeat. |

We’ve been on the horn with MSC. Have another customer with two reefers of food items on a vessel that was scheduled to arrive 3/31, aside from the other customer already mentioned. Depending on port rotation, the containers will discharge in either New York or Norfolk. Carrier will declare force majuer, so importers will be stuck with the costs of trucking their containers to the Baltimore area. The food reefers have already been customs cleared. I have to get with CBP and FDA once the carriers indicate where they’ll discharge these containers. You can’t just change the port of entry on a clearance already done.

We don't know enough to draw any conclusions yet. It could be deliberate. It could be incompetence. It could be catastrophic mechanical failure.
Anyone who claims to know which, at this point, is full of shit. |

Loss of power and or steerage of such a large vessel is scary. I'll bet the pilot was yelling so loud he didn't need a radio for port authority to hear him. RIP to those lost in this tragedy. |

Officials were quick to rule out the catastrophe as intentional or an act of terrorism, and an early Cybersecurity and Infrastructure Security Agency (CISA) report found the container ship 'lost propulsion' as it was leaving port.
'The vessel notified MD Department of Transportation (MDOT) that they had lost control of the vessel and an collision with the bridge was possible,' the report said. 'The vessel struck the bridge causing a complete collapse.' Link |

We all know our government lies to us and has no credibility. So we can't trust the official narrative. They did that to us they broke trust and anything the mainstream media or government says should be regarded with skepticism. That is a reasonable approach not tin foil.

Another angle. I cannot believe the main bridge supports were not protected with huge bollards. No protection at all.

I don't have an opinion about anything yet but:
The FBI or anyone else saying there's no evidence of terrorism just means they don't have evidence. It's not a definitive statement and it's not a statement ruling out the possibility. It's just a statement about what they know at present time. |
