The captain of the cruise ship Costa Concordia, which struck a rock and capsized off Italy, told magistrates he informed the ship’s owners of the accident immediately, denying he delayed raising the alarm, judicial sources said Saturday.

Captain Francesco Schettino has been blamed for causing the January 13 accident in which at least 12 people died. He is under house arrest, accused of multiple manslaughter, causing a shipwreck and abandoning ship before all passengers were evacuated.

His statements to prosecutors investigating the disaster, reported in the Italian press and confirmed by judicial sources, underline the growing battle between him and the 114,500-tonne vessel’s operator, Costa Cruises.

The liner, carrying more than 4,200 passengers and crew, ran aground and capsized off the Tuscan island of Giglio as dinner was being served. It is now precariously lying on its side on an undersea ledge, half-submerged and threatening to slide into deeper waters.

Diving crews recovered the body of a woman aboard the ship Saturday, bringing the death toll to at least 12. Twenty people are unaccounted for and hopes of finding anyone alive have all but gone.

Prosecutors say Schettino steered the vessel within 150 meters of Giglio island to perform a maneuver known as a “salute” – a greeting to the islanders. He has admitted that the boat came too close to shore but has denied bearing sole responsibility, saying other factors may have been involved.

According to transcripts of his questioning by prosecutors leaked to Italian media, he said that immediately after hitting the rock he sent two of his officers to the engine room to check on the state of the vessel.

As soon as he realized the scale of the damage, he called Roberto Ferrarini, marine operations director for Costa Cruises.

“I told him: I’ve got myself into a mess, there was contact with the seabed. I am telling you the truth, we passed under Giglio and there was an impact,” Schettino said.

“I can’t remember how many times I called him in the following hour and 15 minutes. In any case, I am certain that I informed Ferrarini about everything in real time,” he said, adding he had asked the company to send tug boats and helicopters.

Costa Cruises Chief Executive Pier Luigi Foschi says Schettino delayed issuing the SOS and evacuation orders and gave false information to the company headquarters.

“Personally, I think he wasn’t honest with us,” Foschi told Corriere della Sera Friday. He said the first phone conversation between Schettino and Ferrarini took place 20 minutes after the ship hit the rock.

“That is too late,” he said, adding the company had only realized the scale of the disaster when the evacuation order was issued, something prosecutors say happened more than one hour after the first conversation between Schettino and Ferrarini.
