The wreckage of the Italian cruise ship Costa Concordia is being raised.
According to the BBC, it will be one of the biggest maritime salvage operations to be undertaken in history.
Workers are slowly lifting the vessel by pumping air into tanks attached to the ship. The refloating operation is expected to take about a week.
The ship will then be towed to its home port, Genoa, where it will be scrapped.
The Costa Concordia struck a reef off the Italian island of Giglio in January 2012 and capsized, killing 32 people.
The wreck was hauled upright in September, but is still partially submerged, resting on six steel platforms. The first stage of the salvage operation is being deemed as very danagerous.
