The damaged side of the capsized cruise liner Costa Concordia is seen at the end of the "parbuckling" operation outside Giglio harbour September 17, 2013. Salvage crews on the Italian island of Giglio raised the Costa Concordia cruise liner early on Tuesday, completing one of the most difficult and expensive wreck recovery projects ever performed. In a 19-hour operation which ended at 4.00 a.m. (0200 GMT), the 114,500 ship was pulled upright by a series of huge jacks and cables and left resting in 30 metres of water on underwater platforms drilled into the rocky sea bed.

A seagull flies past the side of the cruise liner Costa Concordia during the "parbuckling" operation outside Giglio harbour January 12, 2014. Thirty massive tanks filled with air will lift the hulk of the Costa Concordia off the seabed in June so it can be towed away from the Italian island of Giglio where it capsized two years ago, officials said. The 114,500-tonne vessel hit rocks on Jan. 13, 2012, killing 32 people. It was hauled upright in a complex "parbuckling" operation in September but still rests where it capsized, just outside the holiday island's small port. Refloating the Concordia will be one more phase in the largest maritime salvage in history. Where the ship will be dismantled - the final step - has yet to be decided.

People look on as the capsized cruise liner Costa Concordia lies on its side next to Giglio Island September 16, 2013. Engineering teams began lifting the wrecked Costa Concordia liner upright on Monday, the start of one of the most complex and costly maritime salvage operations ever attempted. The so-called "parbuckling" operation will see the ship rotated by a series of cranes and hydraulic machines, pulling the hulk from above and below and slowly twisting it upright.

Francesco Schettino, captain of the Costa Concordia cruise ship, looks on during a trial in Grosseto, central Italy, July 17, 2013. The trial of the captain of the Costa Concordia cruise ship, which capsized off Italy's coast last year killing 32 people, resumes on Wednesday after it was delayed by a lawyers' strike earlier this month. The trial will examine one of the most dramatic marine accidents in recent Italian history, when the huge liner struck a rock outside the port of Giglio in January 2012 and keeled over on to its side, setting off a chaotic night-time evacuation of more than 4,000 passengers and crew. Schettino, accused of abandoning ship before all crew and passengers had been rescued, faces charges including manslaughter and causing the loss of his ship, which still rests on its side in the Tuscan port.
