No but all these stories from the mind molders about concern for port workers even as they say that the port will be open in days makes no sense. Combined with the stories of concern about the crew members aboard the ship I get the sense that they are yapping about the trivial/non existent because they feel the need to say something even as there seems to be a complete embargo on reporting on what happened.
I smell a rat.
I have noticed a rumor of a lack of tugs, which if true might be lack of workers....I want to know what the historical has been on tugs escorting ships under the bridge...something that I have seen no one mention. Tugs are expensive though, maybe the port over the years cheaped out.
The supply chain crisis that effects ocean carriers, truckers and other freight companies is still going on. With the zionist/neocon war in the Middle East, things will only get worse, especially in Europe. I predict more ports on the East Coast will have trouble staying open if the supply chain slow down continues much longer.
IDK about that.
BTW the tug contract is here:

I wanted to figure out how much it would cost to have escorts under the bridge but gave up, but spect that we are talking something like $75K if there are no problems, if the power goes out the price doubles....which would go far in explaining why the port did not require them.
You are doing the yapping about something you know almost nothing about. You leap to conclusions that fit your beliefs.You are a far right.pro-Putin, conspiracy nut.
The 2021 Infrastructure Law provides $350 billion to private companies that are taking over publicly owned bridges. In less than 2.5 years after it was signed into law, Baltimore needs a new bridge. So why did Biden say the federal taxpayers would be forced to pay a private company to build the bridge? Don't they have insurance? How about the cargo ship insurance? I'm required by law to have insurance. Lot of questions yet government remains silent.
Yet here you are, a far left lunatic yapping about something you know almost nothing about. DUH!!

When it comes to electricity and ship's electrical systems he doesn't know WTF he's talking about for the most part.
I will also say the ship should have had all 4 generators running and online with a split high and low bus for leaving port. The emergency generator design tie in is bad.
The report also says, to me, they had a serious short on something that kept tripping the bus tie breakers.

Feel free to point out his errors in his reading of the official report, though that would be besides the point that the experts dont yet have any conclusions on why the power cut out. Saying that the breakers blew is not saying anything.....the prelim report says "we have not been able to figure it out".

His description of how things work was just bad. If you want massive details I can do those a bit later on.
I am not that interested....go with this:
"
The ship left the pier at 0036, released her docking tugs, made her turn and headed outbound in Fort McHenry Channel at a slow bell. An apprentice pilot had the conn with an experienced pilot watching. At about 0125, as Dali was about three ship lengths away from the Francis Scott Key Bridge, the No. 1 high and low voltage breakers both opened and cut off all power to the rest of the ship. The reasons are unknown and are under investigation, with help from the manufacturer.
The two auxiliary engines kept running, uninterrupted, but they were no longer connected to the rest of the ship's systems. Without power to the electrically-driven lube oil pump and coolant pump for the main engine, the propulsion system automatically shut down. It was never brought back online.
Rudder control was also temporarily lost, and the rudder was stuck amidships as the Dali drifted towards the bridge. The emergency generator started up shortly after and restored power to bridge systems and to one steering pump for rudder control. At 0126:13, the senior pilot ordered 20 degrees port rudder. This had a reduced effect on the ship's trajectory, since the propeller was no longer pushing water past the rudder.
The crew manually reconnected the high voltage and low voltage breakers, restoring full power to the vessel. At 0126:39, the pilots called for an urgent tug assist and ordered an anchor dropped.
Shortly after, the ship lost electrical power again. This time, the diesel generator breakers for the No. 3 and 4 generators had opened, cutting off the still-running auxiliaries from the high voltage bus. The emergency generator stayed on and kept providing backup power to the bridge. The No. 2 generator was running on standby and quickly connected automatically, and the crew closed the breakers for the No. 2 transformer (the one previously in use the day before) to bring back low-voltage power for the second time. From the start of the second blackout to the restoration of power took about 30 seconds. "

Still leaving us with "We have not been able to figure out the cause of the power outage after almost two months".

Here's what I'm getting at. The ship lost electrical power and that caused the accident. The generator line up they had contributed heavily to what happened.I am not that interested....go with this:

What they should have had was all four SSDG's (Ship's Service Diesel Generators) up and running. The high voltage and low voltage bus should have been split 'port and starboard.' That's how the US Navy runs things when you set "Sea and Anchor detail" for entering or leaving port. That means that whatever caused the two bus ties between high and low to trip--almost certainly a serious short circuit--takes out only half the high and low bus. This means that most stuff still works. This is why you do it in areas of critical maneuvering like entering and leaving port.
The electrician on watch should have been able to determine if the short was on the high or low bus, and then reenergizes the down half of the bus that isn't effected. That gives you 3/4 of all systems back online within a minute or two at most early on.
From that, the effected, shorted, system could have been isolated and the effected bus reenergized at that point.
A lot of that has to do with how good the engineering crew is and their ability to recognize and deal with a casualty. It sounds like they weren't all that good at that since they tried to reclose the tripped breakers only to have them trip a second time. That says they didn't recognize that there was a serious electrical fault that needed clearing before you reclose the breakers.
The real question needing answering is What was the fault that caused those breakers to trip? That should be fairly obvious as it would take a major short to cause the bus ties to trip.
