Salvaging the Costa Concordia

They are attempting to right the ship in a process called "parbuckling". You can see the line of muck on the superstructure as they begin the process:

From what I've read, they've welded flotation boxes to the side of the ship. They'll pull her upright, float her up and tow her away for scrapping. Lots can go wrong, she could break in two or roll over the other way down the slope of the sea floor. The area is part of a marine sanctuary, so leaving her there to rot, scrapping her in place or pushing the hulk into deeper water are all out of the question.
