Italy’s Civil Protection agency has given the green light to the plan to rotate the Costa Concordia, which remains half sunken off the coast of Italian island, Giglio since January last year.

The removal plan requires salvage crew to slowly rotate the 290-meter ship using a giant steel box, which has been welded to the ship’s side above water, six underwater steel platforms and wire cables from more than 70 hydraulic rams onshore and offshore.

If everything goes to plan, the water will be drained from the ship before it towed to shore.

Italy’s Civil Protection agency said exact dates of removal depend on the calmness of seas near Giglio Island, however, could take place later this month, once final safety certificates are issued, Huffington Post reported.

Meanwhile, the manslaughter trial of the ship’s captain, Francesco Schettino, resumes on 23 September.
