Workers of the U.S. firm Titan Salvage and Italian firm Micoperi take off the swimming pool slide from the Costa Concordia upper deck near the harbour of Giglio Porto on June 23, 2012. Salvage crews began preliminary work this week on preparations to refloat the half-submerged Costa Concordia cruise liner in what is set to be the biggest ever operation of its kind. The cruise liner, operated by Carnival Corp's Costa Cruises unit, capsized off the Tuscan island of Giglio after hitting rocks on January 13. At least 30 people died and two are still unaccounted for.
