Costa Concordia, Giglio Island, recovery operations: The fuel tank located in the Costa Concordia, has been withdrawn for more than eighty percent. When the work of recovery of hydrocarbons, will be finished, can begin the recovery operation of the ship. Several companies, many European and others if other countries, are studying to submit a draft economic recovery possible and simple to implement. It will not be easy.

The Costa Concordia, is the largest passenger vessel ever sunk, more than twice what was the Titanic. The Concordia develops 112,000 tons, against 46,000 of the Titanic. The ship also is in a precarious equilibrium that makes every operation more complicated.
Proposals to make the recovery are various and different: one is to ensure some big balloons under the ship and they straighten it out, but Mike Lacey, secretary of the ‘International Salvage Union, the association of large companies operating in the field of recovery, has explained: “There are no balls of size sufficient to carry out such a task. These can help, but, certainly, alone, can not do the job.”
Some have even suggested, to fill the ship with foam balls and put it back up. A similar operation has already been accomplished in Kuwait and Iceland, but, again, Mike Lacey, explains that it is not feasible because it would take millions of polystyrene balls to do such a thing, balls that are not controllable and you may disperse into the sea, creating another huge problem, that of their recovery.
Another idea is to use huge cranes to try to straighten the ship sideways, just enough to carry out repairs to the hull and then tow it to port. “There are no cranes of this ability, and also, there is no place to put them so they can operate” – Mike Lacey continues – “no, I think that ultimately, the only way is to bring it into slices and take the Concordia away piece by piece. In any case, grope to recover it entire is useless, since that ship will never come back into the water, no one wants to browse above no longer. What we will do I think, is to dissect it into blocks of 200-300 tons may be towed individually, to then be disposed of once in port. Also in this case, however, the problems are not few. Will not be easy to work with this beast.
