Salvage crews began preliminary work at Giglio Island, Italy on June 20, 2012 on preparations to refloat the half-submerged Costa Concordia cruise liner in what is set to be the biggest ever operation of its kind. A barge has moved next to the liner and the ship's radar has been removed from the upper deck. The swimming pool slide and the large yellow funnel will be taken off in coming weeks.The 290-metre-long (951 feet) cruise liner, operated by Carnival Corp's Costa Cruises unit, capsized off the Tuscan island of Giglio after hitting rocks on January 13, 2012. At least 30 people died and two are still unaccounted for. The preliminary work has begun before the ship is stabilized, which will happen in the next few months. The refloat and removal of the ship is set to cost at least 0 million and last about a year. Photo by Eric Vandeville/ABACAPRESS.COM
