Fascinating article about how they're chopping up a capsized cargo ship

A Chain Just Cut Through A Capsized Cargo Ship Filled With Cars And The Process Is Fascinating
David Tracy
Yesterday 3:15PM

Back in September of 2019, a 600+ foot cargo ship called the MV Golden Ray, which was apparently loaded in an unstable fashion with over 4,000 cars, capsized in St. Simons Sound just off the port of Brunswick, Georgia. Since then, responders have been working to remove the ship in sections to send the hulk to the scrapper. November was particularly exciting, as workers used a chain to cut off the first enormous chunk of ship, revealing mangled cars within. Hereís at look at the fascinating way the team pulled this off.

The VB-1000 Lift Vessel

The main player in the complex slicing operation is called the Versabar VB-10000 lift vessel, a gigantic yellow dual-barge crane used for the first time in 2010 and developed in response to hurricanes damaging oil platforms. The company that builds the enormous contraption says capacity of the tall twin-gantries is 7,500 tons, though each of the two trusses is structurally capable of handling over 5,000 ó itís apparently the buoyancy of the barges that limits capacity to 7,500. Speaking of the two barges, each has four 1,000 horsepower thrusters to keep the vessel precisely positioned overtop of the wreckage.

The Cutting Operation

The video clip below from Jacksonville local news channel WJXT shows a nice animation of how T&T plans to remove the ship piece-by-piece using a cutting chain, a huge lift vessel, winches, and the lifting lugs.

Hereís a screenshot of the most important bit. You can see the crane stabilizing the ship via the lifting lugs, and the chain below the ship, wrapped around the hull so that it can make the cut as it reciprocates. Each cut, per St. Simons Incident Response, was expected to take 24 hours, though as youíll read in a moment, it didnít work out that way, as the bow and stern were apparently stronger than expected, per a representative from St. Simons Sound Incident Response.

Basically, they're slicing the ship up into 8 segments so they can lift each one onto a barge and send it to the breakers.

Lots of good pictures in the article as well.

1. My sister lives a couple of miles from there.

She goes to St. Simons village to watch this every few days. I saw the new crane when it was first installed.

4. Very nice for you and her

I bet, once this is all said and done, there will be a really cool time-lapse video of the entire operation.

There is such a video of that Italian cruise ship that grounded and capsized a few years ago. The one with the drunk and cowardly captain.

2. That is very interesting

Helpful hint: Don't buy any of those cars. They probably have bad air bags!

Very cool. Thanks for sharing!
