Costa Concordia salvage to go ahead [Electronics]
The head of the operation, Nick Sloane, told AFP news agency that it was now or never for the Costa Concordia, because the hull was gradually weakening and might not survive another winter.Engineers will try to roll the ship up using cables and the weight of water contained in huge metal boxes welded to the ship's sides - a process called parbuckling.This procedure must be done very slowly to prevent further damage to the hull, which has spent more than 18 months partially submerged in 50ft of water and fully exposed to the elements.More boxes will then be attached to the other side, and the water will be replaced with air to add buoyancy, allowing the vessel to be towed away and broken up for scrap.
If the operation goes wrong, environmentalists warn that toxic substances could leak out into the sea.For the people of Giglio, the salvage operation will be an important moment - and a special prayer was said during Sunday Mass.The small island's economy depends hugely on tourism and the presence of the wreck has discouraged visitors.Motorists coming off the Frederick Douglass Memorial Bridge into Washington are treated to a postcard-perfect view of the U.S. Capitol. The bridge itself, however, is about as ugly as it gets: The steel underpinnings have thinned since the structure was built in 1950, and the span is pocked with rust and crumbling concrete.
District of Columbia officials were so worried about a catastrophic failure that they shored up the horizontal beams to prevent the bridge from falling into the Anacostia River.And safety concerns about the Douglass bridge, which is used by more than 70,000 vehicles daily, are far from unique.An Associated Press analysis of 607,380 bridges in the most recent federal National Bridge Inventory showed that 65,605 were classified as "structurally deficient" and 20,808 as "fracture critical." Of those, 7,795 were both — a combination of red flags that experts say indicate significant disrepair and similar risk of collapse.
