This video explains the official plan presented to the Italian government for the removal of the wreckage of Costa Concordia by Costa Crociere and the salvage experts who won the contract, Titan Salvage and Micoperi.
The decision was made to refloat the ship in once piece and tow it away, as that would have the least impact on the environment. The video explains the process to refloat Costa Concordia.
The Costa Concordia will be subjected to massive stresses when it is hauled upright, in an unprecedented operation that is scheduled to take place on Monday.
The operation to roll the giant ship, which capsized off the Italian island of Giglio on Jan 13, 2012, with the loss of 32 lives, is due to start at first light on Monday.
A complex system of hydraulic jacks and steel cables will pull the ship, which is wedged on two granite pinnacles in shallow water a few yards off Giglio’s rocky shore, into an upright position.
Salvage experts strenuously downplayed the possibility that the 950ft-long cruise ship could break up under the tremendous forces that will be exerted on its hull, but conceded that the plan to raise it had seemed “crazy” until just a few months ago.
If all goes according to plan, the ship then come to rest on a huge underwater platform, made up of steel girders and more than 1,000 sacks of cement.
More than 30,000 tons of steel have been used in the fabrication of all the components required to lift the ship — equivalent to four times the weight of the Eiffel Tower.
The whole operation is expected to take between 10 to 12 hours, with engineers
explaining that the raising has to be done as slowly and gradually as possible to prevent the massive vessel from fracturing.
The operation to lift the Costa Concordia, which will eventually be towed away and broken up for scrap, is the biggest in maritime history. The cost has ballooned to €600 million (£504 million) and is likely to increase further.
