Absolutely, you're not pulling into any port without a pilot, particularly in a vessel of that size, you absolutely need someone with local knowledge of the channels, terminals/piers and tugs.

If they suffered a engineering plant malfunction they could have had all the Baltimore pilots onboard and it wouldn't matter. Now tugs on each side or at least nearby, that would make a difference.

I agree with 92fstech, opening the waterway is the priority. You can get vehicles around without I-695 albeit with massive delays and backup.

It's my understanding that it WAS a local crew that was piloting when the accident took place.

I was talking with a former Navy diver, now commercial diver, I know.

His take is the harbor is closed a minimum of six months.

Why?

It will take three months to mobilize the people and machines necessary to clear the harbor. The machines are the long pole - finding a large floating crane or two on short notice for a long contract isn't easy. Then another three months to sufficiently clear just the channel to allow large vessel navigation.

Rebuilding is at least five, more like ten, years and will run into billions.

Then there is the inevitable litigation.

The tugs are there to pull and orient the ship to/from the terminal, this ship was already clear of her maneuvers and was making steam into the channel, tugs would've helped but, at this point they had already been cast-off.

There's another bridge at Annapolis where they'd need navigation assistance I would assume pilots are necessary.
Are pilots needed to navigate the ENTIRE Chesapeake or, only between anchorages and terminals?

Quite the pessimist. It will be a priority of the Federal Government and people will be impresssed as it will be done quickly. America has the resources and knowledge. It is not going out for bids.

The ship turned amazingly fast, I have not seen a container ship turn like that before. A single screw vessel would have a slight tendency to turn in one direction, but nothing like the video shows.

It is possible that the autopilot system malfunctioned, and caused the boat to turn sharply. Other possibility is sabotage.

I can see it taking months to clear out the wreckage of the bridge, but I simply don't see how it could take 6 months to clear "A" channel for navigation.

It'd be a surprise if autopilot was engaged, when transiting a channel and port area its all about pilot, master, helm and navigator/GPS
Other possibilities....
- Helm threw the rudder in an effort to keep the bow pointed in the channel
- Wind
- There was enough torque in the shaft to effect that movement while the ship drifted

Well find out in the investigation...

All right sailors, why dit it turn to the starboard after losing power?

Single screw vessel, the screw was still turning and that’s what made it turn starboard.

The USN and USCG conduct loss of steering drills every time they sail, to try and combat and prepare for things like this. Same with fires and GQ.


Curious, as someone with absolutely zero experience with watercraft beyond a 25hp tiller-steer outboard on my aluminum fishing boat:

Is the proper reaction to immediately shut down the shaft when this happens?
No, you’d immediately put the shaft in neutral and let it slow down, while putting a step tiller on the rudder or use block and tackle to manually control the rudders

And we're assuming from the outcome in this incident that that didn't happen?
based on the outcome I’d say they didn’t have time to set up emergency steerage or they gambled on getting power back on

Can the shaft be disengaged/reengaged without shutting down the engine (which I assume would take a long time to restart)?

yes the shaft can be placed in neutral with the engine still running. But they had lost power, so the shaft was already free wheeling

If so, how long would that take to accomplish?
just depends, on the 41’ boats it was a one minute job, on the patrol boat it took about ten minutes for the block and tackle to be rigged with experienced crew. One the big ship it was a ten to fifteen minute job to rig it.

They dropped one of their anchors as discussed in the video I posted on the previous page.

Per an earlier post in this thread, there were two pilots on board.

Regarding emergency steering, there are hand hydraulic pumps built into the system which would be used before any kind of block and tackle rigs. However, it's a very slow process as you can imagine.

Reports are coming out that because a mayday was sounded the traffic was in the process of being reduced onto the bridge. I am engaging in conjecture but I would not think that that would have provided time to realize that there were also work crews on the bridge and to get word to them for them to evacuate.

Perhaps once this is repaired they will extend the tug-escort protocols for this harbor (?)

Ship cited for previous propulsion deficiency before Francis Scott Key Bridge crash, crashed in 2016

https://nypost.com/2024/03/26/...ort-authorities-say/

The container ship that apparently lost power and then smashed into Baltimore’s Francis Scott Key Bridge was cited last year for a “deficiency” with its propulsion.

The M/V Dali also crashed while leaving the Port of Antwerp in 2016.

Across 27 inspections conducted since the Dali was built in 2015, two “deficiencies” were flagged, according to records from the Electronic Quality Shipping Information System (Equasis) viewed by CNN.

Chilean authorities gave the Dali a “deficiency” for “propulsion and auxiliary machinery — gauges, thermometers, etc,” in June 2023, according to Equasis records.
