Transcript of "Raising the Costa Concordia"

  1. 1. Raising The Costa Concordia Heres the ingenious $400 million plan to deal with the wrecked Costa Concordia
  2. 2. In January, 2012. the cruise ship Costa Concordia struck a rock off the shore of Isola del Giglio, off the coast of Italy, in the Mediterranean30 people on board the largest passenger wreck of all time lost their lives; twoare still missing.Nearly a year later, the wreck is still sitting off the Italian coast, mostlysubmerged.Because the Costa Concordia is in a nationally protected marine park and coralreef, it must be removed from the area before it can be dismantled, posingcountless difficulties.A CBS reporter visited the wreck and recounted the remarkable salvageoperation, which has a $400 million price tag.Not only is it the riskiest, most complicated, and most expensive salvage planever undertaken, but no one is sure if it will work. The ship weighs 60,000 tons and is filled with seawater.
  3. 3. It is sitting on two underwater mountain peaks. 65 per cent of it is below the surface.
  4. 4. The wreck is an official crime scene
  5. 5. The plan is to rotate the ship upright, and onto an underwater platform
  6. 6. Then it will float up, leaving more of its structure above the surface
  7. 7. And it can be towed away
  8. 8. Before getting on the inclined ship, workersmust take a 4-day mountain climbing course
  9. 9. 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
  10. 10. The steel that makes it up weighs three times as much as the Eiffel Tower It will be embedded in the seafloor
  11. 11. The drill bit will be enclosed in a large tube, to keep debris from contaminating the protected area
  12. 12. 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
  13. 13. 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
  14. 14. They all live in floating barracks, next to the wreck site
  15. 15. How exactly will workers rotate Costa Concordia onto the platform?The plan essentially involves "welding a new ship onto the shipwreck"
  16. 16. That new "ship" will consist of huge, hollow steel boxes
  17. 17. Called sponsons, the biggest are 11 stories tall
  18. 18. 9 will be welded onto the exposed side of the ship, with just 2 inches between them
  19. 19. Then steel cables will connect the sponsons to the steel platform
  20. 20. Hydraulic pulleys will pull the Costa Concordia upright
  21. 21. More sponsons will be welded onto the other side of the ship
  22. 22. Once the ship is upright, the extra buoyancy should make it float
  23. 23. The ship will be floated next summer.Once the process begins, there is no way to stop it, even if something goes wrong!
  24. 24. The backup plan is to break it up where it lies, at a huge cost to the local environment
  25. 25. 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
