Dali Cargo Ship and Port of Baltimore Update

Well done analysis...recommended viewing: In this episode – maritime historian at Campbell University (@campbelledu) and former merchant mariner – discusses the collision between MV Dali and the Baltimore Key Bridge and updates on the situation in and around the port of Baltimore.

From Gab: THERE IS NO CONSPIRACY:

Sailor here. I’m a certified master helmsman with lots of port transit time. Here’s my take on what happened with the bridge incident:

Updated with new information.

The ship in question is the MV Dali. The ship has a fixed pitch prop that makes it difficult to reverse. She has an electric bow thruster, but that only really works at slow speeds and requires electrical power.

The videos show the ship losing power and engines as it approaches the bridge. When the power goes out on a ship like that, the hydraulics that control the rudder stop working.

After losing power, the ship begins to twist in the current, with the aft sliding out of position to port.

They managed to get an auxiliary generator going, which is when the lights came back on the first time, but this did not provide power to the rudder hydraulics.

Then suddenly the engine kicks back on, which is the cause of the black smoke you see. Once the engine kicks back on, the power to the hydraulics is restored and steering is restored, but it wasn’t on long enough to maneuver the ship.

A second ill-timed power-outage seals the fate, not leaving enough time for the ship to swing to port after the current had caused it to twist.

You can seem him try to swing the rudder back over to the port side once he realizes the rudders are working again, but by then it is too late. The rudders on those ships are slow to respond. It can take over ten seconds for the rudders to swing all the way over from one side to the other.

It’s possible they managed to put the engines in reverse which would also cause the her to straighten up down the channel to port.

I’ve had power-outages like this happen on a warship at sea with far more redundancy than this cargo ship has. Things like this can happen. Even with backup generators running, managing the electrical load on a ship like this is complex. It would have taken the engineers some time to figure out how to address an outage. As you can see from the video, the outages did not last long. They just happened at the worst possible time.

There is no conspiracy.

I would need to see some proof of sabotage before I believed this was planned. Killing the power also means killing the ability to steer. If the ship can’t be steered, there’s no way to intentionally aim it at the pier.

The new info comes from this analysis by the YouTuber “whatsgoingonwithshipping” – where he displays the actual track data as opposed to me just eyeballing it.
