The removal plan of costa concordia ( the wreck of the ship, which measures 952 feet in length and weighs more than 114,000 tons) could be divided in six subsequent phases: Stabilisation The first phase involves the anchoring and stabilisation of the wreck to prevent any slipping or sinking along the steep seabed. This will make it possible to work safely even in bad weather. Stabilisation is performed using an anchoring system made up of four submarine anchor blocks fixed to the sea bottom between the center of the wreck and the coast. At the beginning of November, the Consortium announced the completion of the wreck stabilisation. Later, 12 retaining turrets will be installed for use during the parbuckling of the wreck. Strandjacks (individually controlled by computers) mounted on the tops of the turrets are attached to chains (two per turret or a total of 24 chains) that pass under the hull and are fixed to the port side of the wreck.
