The Raising Of The Costa Concordia The Raising of the Costa Concordia follows the recovery of the world’s biggest shipwreck and the great feats of engineering that surrounded the endeavour. The massive Costa Concordia cruise liner that crashed onto the Italian island of Giglio is finally being pulled off the jagged rocks that snared it. The operation is extremely tense. If any little thing goes wrong, the ship will sink or crumble, destroying the pristine waters there. Engineers have been preparing the ship for 18 months, in the largest marine salvage operation ever attempted. Cameras have been following the 500 engineers, divers, welders and crane operators that have been working on raising the ship since it struck rocks near the island of Giglio, Italy in January 2012 and capsized, killing 32 passengers
