What to Do with a 1,000 Foot Wrecked Cruise Ship?

Hugh Pickens writes writes "What do you do with a 1,000-foot wreck that's full of fuel and half-submerged on a rocky ledge in the middle of an Italian marine sanctuary? Remove it. Very carefully. Stuck on a rocky shoal off the Tuscan island of Giglio, leaving the wreck where it is probably isn't an option but removing a massive ship that's run hard aground and incurred major damage to the hull involves logistical and environmental issues that are just as large. First there's the fuel. A half a million gallons of fuel could wreak havoc on the marine ecosystem — the ship is smack in the middle of the Pelagos Sanctuary for Mediterranean Marine Mammals. Engineers may need to go in from the side using a special drill to cut through the fuel tanks in a process called hot tapping. "You fasten a flange with a valve on it, you drill through, access the tank, pull the drill back out, close the valve, and then attach a pumping apparatus to that," says Tim Beaver, president of the American Salvage Association. "It's a difficult task, but it's doable." Then if it's determined that the Costa Concordia can be saved, engineers could try to refloat the ship and tug it back to dry dock for refurbishing. The job will likely require "a combination of barges equipped with winches and cranes" to pull the cruise liner off its side then once the Concordia is off the rocks, "they are going to have to fight to keep it afloat, just like you would a battle-damaged ship." Another alternative is to cut the vessel into smaller, manageable parts using a giant cutting wire coated with a material as hard as diamonds called a cheese wire in a method was used to dismember the 55,000-ton Norwegian-flagged MV Tricolor. Regardless of how the Concordia is removed, it's going to be a difficult, expensive and drawn-out process. "I don't see it taking much less than a year, and I think it could take longer," says Bob Umbdenstock, director of planning at Resolve Marine Group."
