Costa Concordia could remain off the coast of Italy’s Giglio Island longer than expected, as the line ceases removal operations to respond to environmental concerns.

According to Italian media, the company in charge of removing the 290-meter-long ship, Titan Micoperi, has requested more information on the environmental impact of moving the ship after citing a lack of documentation for one of the two removal options.

Project manager, Sergio Girotto said the option to move the ship to Turkey via the world’s largest semi-submersible ship, the Dockwise Vanguard, needed more information.

Media outlet, Corriere Fiorentino, said in that case, the content of the Concordia, including the cleaning products, rotted food and sewage, would need to be pumped out before movement to avoid spilling in Giglio, Europe’s biggest marine sanctuary.

“In a few days we will present answers in order to resume work,” Mr Girotto said,

Costa Concordia has been sitting off the coast of Giglio Island since 2012, when it struck rocks and sank, leaving 32 people dead.

The line has already spent over $1.65 billion on the ship’s removal, including $800 million which was spent on rotating the ship from her side and onto underwater platforms in September last year.
