Baltimore Key bridge collapse

[PSUAVLNC]

1. They were in their channel, about to make a starboard turn to go into the channel that went under the bridge. I've made reference to the harbor chart and posted a link to it twice already.

No sorry, the pilot ordered the rudder hard left indicating he wanted to turn to port. The ship was south bound and west of center channel. Another interesting fact about ships, the stern swings with the rudder, the bow does not lead a turn. The stern swings and when the desired compass heading approaches the pilot orders the helmsman to ease the rudder to steady up on a course.

If you want to steady on the new course, you will have to take the rudder a bit past center to stop the swing. At least on a destroyer you do- I never steered a container ship.

I do stand corrected on where it was coming from- I thought it was in the Curtis Bay Channel, but apparently it was in the Fort McHenry channel. They must have lost steering some time before I had thought to have drifted that far to starboard.

If you want to trade cargo between US ports your ship must be “flagged” in the US. (Jones Act). You cannot load cargo in a U.S. port and discharge it in another US port unless your ship is “Jones Act”. The caveat to that rule is you can stop at a foreign port in between US ports. That’s how cruise ship companies get around the Jones Act. The leave the US and will always call in a foreign port before returning US.

This ship is registered in the Bahamas (according to Wikipedia). Departs from New Jersey and first stop is in Florida,
Royal Caribbean - Symphony of the Seas-Aug 2024.
Something is inconsistent.

I'm surprised at the 31K vehicles/day on this bridge. Our little drawbridge that is being replaced (I've been using a PITA detour for a year now) is 21K/day. I guess this bridge is mainly for trucks and haz/mat vehicles while all the cars are in the tunnels?

The main traffic corridors are 95 and 895, the two tunnels that cross the patapsco. This one goes from mostly industrial to industrial area and has much less traffic.

For cruise ships the passengers are the "cargo" - in this case the passengers that embarked in NJ cannot disembark in Florida. Until that ship calls on a foreign port those passengers cannot disembark in any US port. It happens all the time and the passenger pays a $1200 Jones Act Violation Fee to USCBP and then cannot get back on the ship again.

O.K., the real question. How is this bridge collapse going to affect our recruiting?

I thought the biggest question would be "was the captain COVID vaccinated. "

 

[marshall23]

And Marshall will say she is right to do so because she’s a coach!

Actually, empirical evidence would tell us COACH Mulkey has never been responsible for steering a ship into a bridge.

Question remain as to what she's steering herself into.

Mulkey has displayed a remarkable ignorance of the Streisand Effect. Also: it’s not wise to threaten a defamation lawsuit before the fact because if you end up not suing you’re speaking volumes. Edit How the hell did this end up in the FSK Bridge thread?

I'll defer to this guy.

There are excursions (Disney, Cape Canaveral, Universal, etc.) in FL for passengers that embarked in NJ.

The passengers are going to be passed at Royal Caribbean if they are subject to a $1200 fine per person.

It does not look like the ship is taking on any new passengers in FL.

I found this...
Passenger Vessel Services Act

To me, reading this, the Jones Act does not apply to passenger vessels. A similar Act does apply.

My understanding...
Passengers, on the Royal Caribbean cruise that I referenced, would not violate the act if they continue on the cruise to a distant foreign port and the cruise ends where it began. So, if someone is on a Orlando excursion and misses the ship (for any reason, gets injured and has to spend a night in hospital, just late to port, etc.) they would be in violation of the PVSA. If there is a violation, the cruise line is responsible, not the passenger.

I would have assumed that CJF was at fault.

Exactly right. I did not do a very good job of trying to explain. When a passenger has to voluntarily disembark, say an emergency at home, they pay the penalty.

Thanks Jam,
That was an excellant review (scenario)

Gonna chime in. The $1200 fee to leave a cruise is absolutely. Change the ******* law.

I belive the cruise line pays it, not the passenger. And it is only if there was not a stop at a foreign port at some point before the passenger leaves.
Also, yes change the law anyway.

What's Next For Dali after They Demolish The Francis Scott Key Bridge on the Ship?​

 

[step.eng69]

Just received a preliminary finding by the National Transporation Safety Board in the email concerning the power failure on the Dali's electrical system.

NTSB Releases Report on Cause of Key Bridge Collapse​

Sept. 13, 2024
The Dali's electrical system may have failed because of a loose cable

Investigators with the National Transportation Safety Board (NTSB) have released an initial report of some of the causes of Baltimore’s Francis Scott Key Bridge collapse, including a loose cable that could have caused electrical issues on the Dali cargo ship.

When disconnected, the problematic cable triggered an electrical blackout on the ship similar to what happened as it approached the bridge on March 26, according to the new documents by the NTSB.


The documents don’t include any analysis or conclusions, which will be released later in the board’s final report.

The Dali was leaving Baltimore bound for Sri Lanka when its steering failed because of the power loss. It crashed into one of the bridge’s supporting columns, destroying the 1.6-mile span and killing six members of a roadwork crew.

Safety investigators released a preliminary report earlier this year that documented a series of power issues on the ship before and after its departure from Baltimore. But the new records offer more details about how its electrical system may have failed in the critical moments leading up to the collapse.

The Dali first experienced a power outage when it was still docked in Baltimore. That was after a crew member mistakenly closed an exhaust damper while conducting maintenance, causing one of the ship’s diesel engines to stall, according to the earlier report.

Crew members then made changes to the ship’s electrical configuration, switching from one transformer and breaker system to a second that was active upon its departure. That second transformer and breaker system is where investigators found the loose cable, according to investigative reports.

Engineers from Hyundai, the manufacturer of the ship’s electrical system, said the loose cable could create an open circuit and cause a breaker to open. The engineers disconnected the cable as part of a simulation, which resulted in a blackout on the ship.

The new documents also included various certificates issued after inspections of the Dali pertaining to its general condition and compliance with maritime safety regulations.

Investigations are still ongoing according to the NTSB, with the agency’s final report on the causes of the crash to come.
