Salvage master Nick Sloane (C) waves as he leaves Giglio harbour towards cruise liner Costa Concordia during the refloat operation at Giglio Island July 23, 2014. The massive hulk of the Costa Concordia is nearly ready to be towed away from the Italian island where it struck a rock and capsized two-and-a-half years ago, killing 32 people, officials said on Sunday. The 114,500-tonne Concordia has been slowly lifted from the sea floor since Monday, when salvagers began pumping air into 30 large metal boxes, or sponsons, attached around the hull. A convoy of 14 vessels will then tow the Concordia to a port near Genoa, where it will be broken up for scrap, completing one of the biggest maritime salvage operations in history.
