The wrecked Italian cruise ship Costa Concordia is being raised in one of the biggest maritime salvage operations in history.
Workers are slowly lifting the vessel by pumping air into tanks attached to the ship. The refloating operation is expected to take six or seven days.
The ship will then be towed to its home port, Genoa, where it will be scrapped.
In January 2012, the Concordia struck a reef off the Italian island of Giglio and capsized, killing 32 people.
The wreck was hauled upright in September but is still partially submerged, resting on six steel platforms
Hundreds of divers and engineers have been involved in operations to salvage the Concordia, which is twice the size of the Titanic.
The captain, Francesco Schettino, is on trial for manslaughter and abandoning ship, charges he denies.
