re: Cruise Ship Costa Concordia - MERGED THREADS

The seabed on which the Concordia is situated is not that steep as I thought it was.
It goes from situ Concordia (approx 7 - 8 meters D) stretching over a (.96) nautical mile to 60+ meters.

It depends now on their working culture and of course organisational skills if they advance sufficiently to have the carcass lifted before fall. About 5 months before the weather becomes unstable.

re: Cruise Ship Costa Concordia - MERGED THREADS

An update advising of some "slippage" of the Concordia . . . .
Name: COSTA CONCORDIA Costa Concordia - Type of ship: Passenger ship - Callsign: IBHD - vesseltracker.com
IMO: 9320544
Time: 14-06-2012 20:44:40 UTC

NEWS:
The wreck of the "Costa Concordia" has shifted. The stern sank about four metres, the foreship two metres deeper. Divers resumed their search for the last two missing persons meanwhile in some regions of the wreck. A platform of the salvors Titan-Micoperi has reached the port of Giglio and is to be equipped with two cranes in order to right the wreck which, after its salvage, will probably be towed to Livorno.

re: Cruise Ship Costa Concordia - MERGED THREADS

I'll stick with my original scrapped on site bet. But it should be interesting to watch them try.

re: Cruise Ship Costa Concordia - MERGED THREADS

I saw a large spudding barge has been brought in, they say its to keep the wreck from shifting any more. Not a whole lot of interest about it over at the CC forums.

re: Cruise Ship Costa Concordia - MERGED THREADS

Working culture with the combo Italy - USA is not very promising. I am afraid Sabrekai will be finally right.

re: Cruise Ship Costa Concordia - MERGED THREADS

Heres the plan.

The spud barge will be used to keep the wreck from sliding farther. It will also be used to build the girder structure for righting the ship and the underwater platform where the winches will be mounted.

Costa Concordia refloat to be biggest in history

Maybe, maybe not. As was noted, this ship is 115,000 tons. The WWI/WWII two battle ships righted at Pearl were in the 40-50,000 ton class.

I'm also curious as to how that spud barge is going to keep 115,000 tons from moving if a storm gets up and the wreck starts bouncing down slope.

We shall see. The time table has been released as well.

Work on Costa Concordia salvage project begins - Sun Sentinel

re: Cruise Ship Costa Concordia - MERGED THREADS

Deepwater oil platforms are exposed to worse. Are bigger. Have more windage. And still, all it takes to hold them still are anchors. All these guys have to know, is how to apply anchors and cables.

As for 'maybe maybe not' if this ship is in excess of twice the tonnage of a battleship, is longer, wider, and taller than a battleship...What's to maybe about?

I'd expect the hardest part to be calculating the volume/mass/motion of the water inside the hull, and assuming their are CAD files from the construction, even that is just donkeywork today. What a great opportunity to teach schoolkids about how useful mathematics can be in the real world!

Are we speaking of weight or volume, both expressed in tons for ships?

re: Cruise Ship Costa Concordia - MERGED THREADS

There is some difference between deadweight and gross tons. The deadweight is the displacement while gross tons includes the total volume of the vessel, from keel to funnel.

Anchoring is out of the question to secure the vessel: the slope is seawards and any positioning of anchors outside the vessel is total clueless. The spudbarge might be an idea but the question is can it lock the Concordia in situ.

It is not only the deadweight of the ship, but also the volumetric mass of water inside the hull that should be kept in place.

Time is moving fast and I see no real progress in the whole expedition. We have two to three working months in the Med left, afterwards the weather will become unstable/unreliable.

I do not believe in a successful end.

Battleships of the Iowa class had a displacement (weight of water displaced by the ship) of 45,000 tons. The Costa Concordia has a gross tonnage of 114,000 tons (a measure of the ship's volume.)

You're comparing "rocks to balloons."

re: Cruise Ship Costa Concordia - MERGED THREADS

Costa Concordia Specs:

Gross Tonnage: 114,147 tons. Measurment of the vessels overall internal volume, not the displacement (weight) of the vessel.

Displacement: 51,387 tons. The actual weight of the ship.

Summer deadweight: 8,900 tons. Deadweight is how much weight a ship is carrying or can safely carry.

re: Cruise Ship Costa Concordia - MERGED THREADS

Compared to modern cruise ships, the Iowa isn't nearly as large as cruise ships and freighters.

Battleship USS Iowa, Harbor Channel, Richmond, CA:



Car carrier Cetus Leader (gross tonnage 62,510 tons, weight 21,447 tons), Carquinez Strait, Benicia, CA:

re: Cruise Ship Costa Concordia - MERGED THREADS

The capsized battleship Oklahoma weighed about 30,000tons at the time of her sinking at Pearl Harbour. Eight months or so was required to prepare the ship and site for righting, and four months to actually right and refloat the ship.

Here is another animation that shows how the underwater cranes will right the ship.

Once submerged anything buoyant will be contributing in making the ship lighter. The unknown is the amount of soakage, which will make the ship heavier to raise.
