Operations will be divided into four basic stages:
- After stabilizing the ship, a subsea platform will be built and caissons that can be filled with water will be fixed to the side of the ship that is out of the water
- Two cranes fixed to the platform will pull the ship upright, helped by the caissons, which will be filled with water
- When the ship is upright, caissons will also be fixed to the other side of the hull
- The caissons on both sides will then be emptied, after treating and purifying the water to protect the marine environment, and filled with air.
Once floated, the wreck will be towed to an Italian port and dealt with in accordance with the requirements of Italian authorities.
The plan was selected by an evaluation team with specialist representatives from Costa Crociere, Carnival Corporation & plc, London Offshore Consultants and Standard P&I Club, with the collaboration of RINA and Fincantieri, because it best fulfills the main objectives of the operation — removal of the wreck in one piece, minimal risk, minimal environmental impact, protection of Giglio’s economy and tourism industry, and maximum safety.
