Total bridge collapse in Baltimore...

What’s the old saying? If you ever build a bridge that fails, you better be under it.. However that ain’t applicable here, though I am betting the captain and harbor pilot are probably wishing they were under it.

“I’m going to need you to build a bridge that can withstand the impact of a 100,000 ton cargo ship traveling at 8knots.”

Still waiting for a statement from either one of those two. When all is said and done Im curious who is going to be getting sued, gonna be a long list unless it really was tourerists.

I said as much lol… so they had power problems they were trying to sort about an hour beforehand? A few folks are going to get dropped in the grease…

Hell she's up there with the latest Nimitz, H.W. Bush and the Ford Class, just without the reactors.

I am willing to bet fuel filters/RACOR for the generators. Either someone swapped out filters while she was berthed and did not clear any trapped air after the swap, or dirty fuel. I would also check fuel from the settlers and the day tanks.

She has 5 generators onboard with +20K kVA. I am going to guess they had generators (2 min) paralleling with one on STNDBY. With the fuel issue, the paralleling generators started dropping RPM, thus UV and Freq issues, and breakers tripped. That is when you see the first power outage. The CE or EoW then switched over to the STNDBY generator, and that is when the lights came back on assuming that they were not using a Power Management System. Lights go out again when the STNDBY generator goes off line due to same fuel issue. The third time that the lights come back on is probably because the Egen was online, and has an independent fuel source. The Egen requires anywhere from 30 to 45 seconds without voltage on the main bus to kick on. Once all of the ER generators were failing, CE or Master/Capt probably directed to remain on Egen so atleast they would have minimum vital systems (half of the steering HPU, cooling pumps, etc.).

The dark plume of exhaust is when the Master when from full ahead for maximum thrust across the rudder to crash stop/full astern. Curious as to how the main shaft responded.

They do not maneuver in harbor under any automation, so no AP or Autotrack, it is manually controlled at the helm or wing stations.

There are two pilots: a Docking Pilot to take her away from the berth and a River/Bay pilot to sail and navigate from the channel down to the Bay opening. Tugs are only there to assist when moving away from the berth, and typically they are not "made up"/secured with lines. This vessel has thrusters, so she can handle normal environmental dockings by herself. After the vessel moves from the berth, the assist tugs depart because they are not escort tugs, and they have other vessels to assist or go back to the berth for downtime.

You can see from the AIS tracking that one of the assist tugs turned around and tried to return to the vessel to assist but was too late with too much distance to cover.

It's wild thinking about how much time it takes and comparing it to footage in real time. You're sailing along like you have a thousand times before. First cut out. That's fine, we have backups. A 30 second delay for everything to get synch'ed up and back online feels like the blink of an eye normally, but it must feel like an eternity when you're coasting toward a bridge. Then for it to happen again. That's got to be a code brown at that point. Another 30+ seconds for the next attempt. All of that elapsing in barely over three minutes. Lots of people talking about how they would have done things differently but it's not a lot of time to handle all that and stop something that absolutely massive.


How a lot of people are sounding-

Even fully manned with 5-6k sailors and an entire carrier air wing?

"Publicly" a fully loaded Nimitz is displacing "roughly" 102,000 tons.
MV Dali is showing 116,851 fully loaded.

Great write up - are you a First, Third Mate, or "other" civilian Mariner? Is this ship diesel electric? In other words no main engine/s connected through reduction gears to the shaft? It's hard to believe fuel filter swap would cause an identical issues for all engines, (at nearly the same time) considering 2 were online (your thoughts) with 1 in standby. Earlier in this fun thread I asked about when the tugs were released, but later viewed the AIS video and I did see the tugs released after the ship was pointed towards center channel, so they were released. I also agree with your thoughts that the helm would be manned until the ship cleared the harbor and increased to PIM speed in open waters allowing for autotrack. WRT cause of the collision, this sounds like an unfortunate chain of events, involving equipment failure (electric plant switchgear?) coupled with probably human error.

"Publicly" is a good way to phrase it. I was stationed on the Carl Vinson and "publicly" its top speed was said to be 30 knots but it was somewhat faster than that.

You misspelled "shitload".

Well, he’s a multi millionaire with millions of followers and has a giant ranch in Texas all while doing the lords work ….

I would love to be that retarded.

Let’s screen shot this for when it finally comes out in 2035 shall we?

Yep, has run a very successful satirical "news" program. I guess he's not retarded, just prays on them

I wonder what sort of insurance the shipping company carries.

I can't imagine there's been many "accidents" in history that cost this much.

 

[Deceptive]

It is always interesting when different events happen to see the broad spectrum of expertise and experience people on this forum actually have. In contrast of the meth heads on Facebook commenting about how every event is some grand conspiracy that they have immediately debunked with the vast experience in stealing catalytic converters and copper wiring.

Confirmed by Sonar and TMA conducted by yours truly. Those big ships are fast movers - not as fast as a torpedo though.

Old Joe has already said the Government is going to pick up the entire cost.
You see, that way there will be no "real" investigation, like what an Insurance company would do.
