In regards to salvage:

When the search for survivors and bodies is complete, Dutch salvage firm Smit International will remove the vessel’s fuel as requested by the ship’s owner and insurer. Smit has also offered to remove the wreckage of the Costa Concordia, but the owner has not contracted any firm for this. Carnival Corporation has issued an investor disclosure stating that “The vessel is expected to be out of service for the remainder of our current fiscal year if not longer.”

On 16 January, the CEO of Costa said that the ship could be refloated by giant inflatable buoys and then tugged away. However, he called it “one of the most difficult [undertakings] in the world.”

The Costa Concordia weighs 114,500 tons. The Titanic only weighed 46,328 tons.
