Costa Concordia Salvage Question

It does not start at 4:44 for me. It starts at zero, and it’s a 20:42 video. I do not have an account on youtube.

Bumped.

PBS’s Nova will rebroadcast a documentary about the salvage operation on May 1- check local listings: https://www.pbs.org/video/nova-sunken-ship-rescue-preview/

If you can find a copy of “On The Bottom” by Commander and later Rear Admiral Edward Ellsberg.
You will find a true story of the salvage of the U.S. Navy Submarine S-51. Short version: Over a period that lasted about two years there were two major diving seasons during which Hard Hat divers closed up interior compartments and filled various holes. Holes that ranged from sheared rivets to major hatchways. A large part of the second diving season the divers rigged pontoons and prepared to float the Sub.

Very interesting reading.

Note however the major differences in circumstances and available technology.

Respectfully yours, Zuer-coli

A bit late, but in response to others in aggregate… Uprighting a ship is extremely dangerous, the wiki site says it has 114,147 gross tonnage, that’s nothing like a canoe or a shipping container on a truck. So, probably lotsa calculations as to how to right the ship safely and not cause any more damage.

But, looking at the wiki, man, someone made a bad navigation decision. I’ve never piloted a ship, and I’ve never been a captain, but I can’t imagine the risk of cutting the route that much shorter would save that much more money to make it worth it. Just an IMO.

Also, for those that have never been, the below decks part of a ship is like a honeycomb, mainly to contain a situation like this. However, the six hour evacuation time is well past the required 30 minutes. This is like the 737 MAX were industry had a lot more day in the regulations compared to public safety.

It wasn’t about saving money - it was a “sail-past salute.” From the Costa Concordia disaster Wikipedia page:

I just got done reading a history of the Seabees published in November, 1944 and the author mentioned that is how the LSTs would beach themselves, only they’d drop an anchor a hundred or so yards out so they could winch themselves off of the beach again. He said specifically how the skippers would have to suppress their life-long “don’t touch the bottom” instincts to do a proper job.

The Seabees would get involved because, especially in the South Pacific, reefs could prevent the ship from reaching the beach proper and the Seabees would link together 5x5x7 navy lighterage boxes to make a floating quay to reach out from the beach to the LST. He mentioned how they would lie in parallel several yards apart and when a ship was emptied the quay would be angled over to its neighbor while it backed off for another to take its place.
