ROUGH CUT - NO REPORTER NARRATION
The complex and ground-breaking operation to refloat the cruise ship Costa Concordia off the coast of the Italian island of Giglio got underway at 0400GMT on Monday (September 16).
The 114, 000 tonne ship is being hauled upright using a process known as parbuckling.
Divers have pumped 18, 000 tonnes of cement into bags below the wreck to support it and stop it breaking up during the operation.
It's part of a salvage operation estimated to cost at least $300 million.
At least 30 people were killed when the ship manoeuvred too close to the island and it a rock in January 2012.
Its captain is on trial for manslaughter and causing the loss of the ship.
Four crew menbers and a Costa Cruises company official were jailed in July for their part in the accident.
