After rescuing a burning ship from pirate-infested waters off Yemen and a sinking oil rig in the Gulf of Mexico, South African salvage master Nick Sloane faces his biggest test yet off an idyllic Mediterranean island. The 52-year-old says the attempt to float the Costa Concordia cruise ship, due to begin on Monday, is his “most challenging” yet in a career that has taken him to six continents and two warzones. The Zambia-born Sloane was flown to the Italian island of Giglio in 2012 from New Zealand, where he was working on a spill from the MV Rena oil tanker, to tackle the biggest ever salvage operation of a passenger ship. He has led an international operation with hundreds of salvage workers including divers, welders and engineers operating 24 hours a day around the rusting 290-metre (951-foot) hulk, which is bigger than the Titanic. Sloane’s team successfully raised the keel upright last year in an operation that some thought impossible. Starting on Monday, they are planning to re-float it to be towed away for scrapping later this month in Genoa. “By the end of July, the Costa Concordia is gone from Giglio,” Sloane said in one of his video updates for the operation’s website — theparbucklingproject.com. When the refloating of the 114,500-tonne ship gets under way using giant sponsons welded to its sides for buoyancy, Sloane will be the one giving the commands. The ruddy salvage master hit a snag in 2012 when storms hampered the operation and there were serious difficulties drilling into the granite seabed to install a metal platform to hold the ship stable. There is now concern that the ship may fall apart or fail to float, which would likely condemn it to the sea bed. - A seafaring ‘Russell Crowe’?
