The first phase, which was regarded as one of the most delicate steps of the entire recovery plan, consisted of dislodging the hull from the rock onto which it has molded itself.
"We can now say the hull has been freed from the rocks. It has been a slow, smooth process," project manager Sergio Girotto said.

Steel cables tightened by hydraulic jacks began exerting a force of 2,000 tons on the ship's rusting hull.
"We raised the pulling force through several steps. The hull detached itself from the rocks when a force of about 6,000 tons was applied," Girotto said.
The Concordia is now rotated by 3 degrees. The operation requires a 65-degree rotation. From now on, technicians expect that the rotation can proceed with a gradually decreasing pulling force.
Franco Gabrielli, head of the civil protection agency added that underwater cameras show a large deformations on the starboard side of the ship.
"This is another confirmation that the parbuckling had to be done as soon as possible. We are keeping our eyes open as issues can occur even at the end of the operation, but so far we can say that our models and projects have proved to match the reality," Gabrielli said.
