re: Cargo ship revs up engines and steers into Bridge support

This! The first thing props on big ships do when engaged in full power is push the stern SIDEWAYS, seems counterintuitive but I work in the field and before the props start pushing water forwards or backwards (depending if in forward or reverse ) is they push water SIDEWAYS until laminar like flow is achieved. Ships malfunction more than one might imagine, without hard evidence this just seems like a freak accident. Had this happened a few minute later there'd have been no collision with the bridge piers. What surprises me, considering the amount of ship traffic there is that there were no bulwarks around the piers to prevent/mitigate a collision. That is a very busy port area. The Delaware Memorial bridge has these bulwarks as do other bridges like the one in Tampa Bay that had a similar incident not too many years ago.

A harbor pilot was aboard.

I don’t care if they from mars with pink and purple poke dots. They either intentionally did this or someone remoted in to sabotage. Either way it was no accident. How the fbi said 5 hours later that all is good and no foul play was involved is laughable. They may or not be correct but 3 to 4 hours after the “accident” is just ridiculous

I wouldn’t laugh. We have a first-rate clown running the DOT.

Calling out someone that does not know what they are talking about on a message board for it is what I seek and did.

Waboo the shrimp boat captain says different.

It's called prop walk and you can turn a boat completely in a circle with it in perfect conditions and a single prop.
What I saw there looked more like slewing around dragging the port side anchor after sailing over it. I suspect the smoke was them punching it in reverse and praying. This could also have added to that turn. They slowed down hard after that anchor went down. Had they just had a few more yards it probably would have been ok.

Let’s think about this rationally. You or I was not on that ship right. You nor I can say how the bow thrusters or how the thrusts from the main engines were set. What I can say is that with the tide and currents that were occurring and the trajectory of the ship that loss of power even with the wind would have had a dramatic change on direction from the ship. With that being obvious from the video why would upon power recovery would a captain/crew make such a drastic change of course when the ship was basically following the course intended. Someone captaining this ship would never make the mistake. Also, there was a harbor asst capt aboard to assist with exiting the harbor. I find it hard to believe that incompetence could cause this. They either intentionally did it or someone remoted in and caused it. You can believe what you want to believe.

As I understand it there were two Baltimore pilots. The Master of the vessel is ALWAYS in charge, his ship. The Master gives the con or control to the pilots but he is still responsible. Yes, all protocols were followed correctly as far as I've heard, and yes calling local authorities certainly saved lives. It's just an unfortunate major marine incident. RIP to the lost souls,

The only thing that gives me pause here in assuming it was intentional is this: if evidence existed that the ship’s power & navigational systems were somehow remotely hacked or intentionally sabotaged, you can bet your bottom dollar the FBI would be claiming either Putin or MAGA white supremacists did it.

As a layperson, I believe this YT channel commentator offered some knowledgeable & interesting analysis of this catastrophe:
VIDEO LINK:youtube.com/@wgowshipping
In the two videos devoted to the Dali disaster, the host offers a track of the ship’s approach to the bridge and also provides his opinion on what was happening on the ship as it approached the bridge abutment.

but in this video clip notice how the ship instantly has the engines fire up with the exhaust plume in time to steer right into the main support beam.
It’s likely the captain threw it in reverse full throttle with the rudder turned to swing the front of the ship away from the beam. But when it lost power again having the rudder turned would cause it to turn toward the beam if drifting forward.
Example: your boat is drifting towards a beam a little to your right. You turn to the right and reverse causing the bow to swing towards the left, then turn left and throttle forward, missing the beam. If you lose power before the reverse can swing the bow then the forward drift along with the rudder turned right would steer you toward the beam, not away.
Anyone who has ever driven a boat knows this. I actually had a scenario on my ski boat on the Ms river where my engine quit and almost drifted into a buoy and I got it started and reversed in this exact manner to avoid it.
