The focus now for Italian authorities is on recovery rather than rescue.
The hulk of the Costa Concordia is unstable and it is feared it could shift from the rocks on which it is lying amid worsening weather. Specialist divers are keeping a close eye on conditions.
Eleven people are known to have died out of more than 4,000 passengers and crew.
It was last Friday when the ship struck a rock, just metres from the shoreline, tearing a large gash in its side. Up to 24 people are still unaccounted for.
Hopes of finding survivors have now all but disappeard. Attention is shifting to the threat of an environmental disaster off the Tuscan coast. The ship is holding more than 2,300 tonnes of fuel and pumping by salvage crews, a risky process in winter seas, is expected to take at least two weeks.
