The 600 million euro ($810 million) removal project, which has already run nearly twice its original cost estimates, is the most ambitious ever attempted for a ship the size of the Concordia.
In a statement, the head of the civil protection agency, Franco Gabrielli, expressed condolences for the death and recalled the dedication of people working on the wreckage, saying they had worked "for two years without a break, in difficult conditions not without risks, to achieve the common goal of removing the Concordia from Giglio."
The ship's captain is currently on trial for manslaughter, causing a shipwreck and leaving the ship before all passengers were evacuated. Prosecutors have accused him of taking the ship off course in a stunt to bring it closer to Giglio. Capt. Francesco Schettino has said he saved lives by steering the ship to shallow waters after it ran aground on a reef that wasn't on his nautical charts.
On Friday, Italy's highest court let stand plea bargains reached by five other Costa employees.
Costa is a unit of Miami-based Carnival Corp., the world's largest cruise line.
