Costa Concordia to be refloated in two weeks

Costa Concordia to be refloated in two weeksThe wreck of the Costa Concordia is due to be refloated in the next two weeks in the latest stage of the most expensive ship recovery operation in history.

The salvage could involve a semi-submersible boat effectively carrying the ship from its resting place off the Italian island of Giglio to Genoa to be dismantled.

Costs to insurers have spiralled to almost £1.2 billion because wrecks are usually cut into pieces and carried away. But Italian authorities have decided that such a move would risk an environmentally sensitive stretch of coastline so the ship is being removed in one piece.

Captain Rahul Kanna, a ship insurance specialist at insurer Allianz told the Mail in Sunday: “The primary reason for the cost is the method of removal. It sets a very dangerous precedent.”

Costa Concordia hit rocks in January 2012 killing 32 people.

The ship was turned upright last September after salvage contractors reinforced the seabed beneath it.

Modern shipping is creating the possibility for much bigger losses as ships grow in size and start to use remote Arctic shipping lanes, insurers are warning.

“Any losses in the Arctic would be a logistic nightmare to arrange rescue and salvage,” Kenna was reported as saying.

Semi-submersible vessel to give Concordia a lift

*InsightOne of the more amazing sights when the space shuttle program was in its prime was the 83-ton shuttle atop a Boeing 747 being ferried from its landing field at Edwards Air Force Base in California. The shuttle needed an assist because, other than its launch and return from earth orbit, it could not fly on its own.

Something similar may be in store for the partly raised Costa Concordia cruise ship. The salvage team for the Concordia has secured an option to use the Dockwise Vanguard to transport Concordia, which would be a first for the world’s largest semi-submersible vessel.

Dockwise is a Dutch firm that specializes in semi-submersibles. The vessels fill their ballast tanks to sink below a cargo, and then expel water to float them on large, flat cargo decks.*TomStieghorst

The Dockwise approach offers time and energy savings over towing large loads. Yacht captains have been using the Dockwise for years to transport their boats on long-distance journeys, saving wear, tear and crew costs.

But Dockwise Vanguard was not built for small payloads like mega-yachts. It was built to transport marine oil- and gas-drilling rigs, such as the Chevron Corp.’s 53,000-ton Jack/St. Malo oil platform, which it ferried from South Korea to the Gulf of Mexico last year.

The Concordia would be a bigger bite. According to the salvage team, Concordia will weigh about 75,000 tons, or about 1.5 million pounds, once it is refloated this June.

Dockwise Vanguard can handle it. The 900-foot-long ship, which was delivered last year, has a rated capacity of 110,000 tons. Of course, such a unique vessel doesn’t come cheap. The salvage team has paid $30 million just to secure an option to use the Vanguard for the job.

Without it, the Concordia would be towed in the conventional manner to port. But the seaworthiness of a ship that has been lying on its side in the ocean for two years is an open question.

What would it look like? You can see an online animation by Boskalis, the Dutch parent company of Dockwise, which shows how the Concordia would be loaded on Vanguard.

For the cruise industry, it can’t happen too soon.

Concordia: Search for missing officially called off

Concordia: Search for missing officially called off

Italian officials have permanently called off the search for bodies aboard Costa Concordia – the conditions inside have became too dangerous for the divers.

“We have definitively stopped the underwater search inside the ship,” a spokesman for the fire brigade on the island of Giglio was quoted as saying by AFP.

A total of 17 bodies have been recovered, and 15 people remain missing.

The captain, Francesco Schettino, remains under house arrest facing charges of manslaughter and abandoning ship.
