Raising the sunken Sewol is likely to be a Herculean task that could take several months to complete. In 2010, it took one month to salvage the Cheonan warship, which was five times smaller than the ferry and broken in two. Four large marine cranes, including a Samsung Heavy Industries moder with a hoisting capacity of 8,000 tons, are currently deployed to the site where the Sewol is submerged. Experts propose using a floating dock to help raise and move the hull.
