Not only is it the riskiest, most complicated, and most expensive salvage plan ever undertaken, but no one is sure if it will work.

Here's The Ingenious $400 Million Plan To Deal With The Wrecked Costa Concordia
Alex Davies

costa concordia salvage operation 60 minutes

CBS News
In January, the cruise ship Costa Concordia struck a rock of the shore of Isola del Giglio, in the Mediterranean.

30 people on board the largest passenger wreck of all time lost their lives; two are still missing. Nearly a year later, the wreck is still sitting off the Italian coast, mostly submerged.

Because the Costa Concordia is in a nationally protected marine park and coral reef, it must be removed from the area before it can be dismantled, posing countless difficulties.

In a report on the efforts to remove the wreck, 60 Minutes' Leslie Stahl visited the site and recounted the remarkable salvage operation, which has a $400 million price tag.

Not only is it the riskiest, most complicated, and most expensive salvage plan ever undertaken, but no one is sure if it will work.

The ship weighs 60,000 tons and is filled with seawater.

CBS News
It is sitting on two underwater mountain peaks. 65 percent of it is below the surface.

CBS News
The wreck is an official crime scene.

CBS News
The operation, which will cost about $400 million, is being paid for by insurance companies.

CBS News
The plan is to rotate the ship upright, and onto an underwater platform.

CBS News
Then it will float up, leaving more of its structure above the surface.

CBS News
And it can be towed away.

CBS News
Before getting on the inclined ship, workers must take a 4-day mountain climbing course.

CBS News
The underwater platform is being built in northern Italy. The steel must be transported through the Adriatic Sea, around the boot of Italy, and up to the wreck.

CBS News
The steel that makes it up weighs three times as much as the Eiffel Tower. It will be embedded in the seafloor.


CBS News
The drill bit will be enclosed in a large tube, to keep debris from contaminating the protected area.

CBS News
For now, the ship is held in place by steel cables, but strong storms could dislodge it. Then it would sink to the seafloor, making the salvage operation near impossible.

CBS News
111 salvage divers are currently working on the salvage operation around the clock, in 45-minute shifts. They attached the cables holding the ship where it is.

CBS News
They all live in floating barracks, next to the wreck site.

CBS News
How exactly will workers rotate Costa Concordia onto the platform? The plan essentially involves "weld[ing] a new ship onto the shipwreck," Stahl reports.

CBS News
That new "ship" will consist of huge, hollow steel boxes.

CBS News
Called sponsons, the biggest are 11 stories tall.

CBS News
9 will be welded onto the exposed side of the ship, with just 2 inches between them.

CBS News
Then steel cables will connect the sponsons to the steel platform.

CBS News
Hydraulic pulleys will pull the 'Costa Concordia' upright.

CBS News
More sponsons will be welded onto the other side of the ship.

CBS News
Once the ship is upright, the extra buoyancy should make it float.

CBS News
The ship will be floated next summer. Once the process begins, there is no way to stop it, even if something goes wrong.

CBS News
The backup plan is to break it up where it lies, at a huge cost to the local environment.


CBS News
If all goes well, the 'Costa Concordia' will be cut up for scrap, far from Giglio. It is so large, the process will take 2 years.

Thanks J.L. for this great post and the link to the fantastic photos and illustrations. This is one massive undertaking and I'm surprised that it will only cost $400 milion, I would have thought closer to $I billion. Read, viewed and noted.
