GIGLIO ISLAND, ITALY: Authorities have given the final go-ahead for a daring attempt today to upright the crippled Costa Concordia cruise liner from its side in the waters off Tuscany, a make-or-break engineering feat that has never before been tried in such conditions.
The ship capsized there 20 months ago, and Italy’s national Civil Protection agency waited until sea and weather conditions were forecast for dawn before giving the OK to try to right it. In a news release Sunday, the Civil Protection agency said the sea and wind conditions “fall within the range of operating feasibility.”
The Concordia struck a reef near Giglio Island the night of Jan. 13, 2012, took on water through a 230-foot gash in its hull and capsized just outside the harbor. Thirty-two of the 4,200 passengers and crew members died. The bodies of two of the dead have never been recovered, and may lie beneath the wreckage.
Never before have engineers tried to right such a huge ship so close to land. If the operation succeeds, the Concordia will be towed away and broken up for scrap.
Salvage experts had originally hoped to right the 115,000-ton vessel last spring, but heavy storms hampered work. Crews have raced to get the Concordia upright before another winter season batters the ship against its rocky perch — damage that would increase the chance that it couldn’t be towed away in one piece.
Salvage master Nick Sloane seemed optimistic in the final hours before the operation began, saying Sunday that testing of the machinery in recent days had actually lifted the 985-foot ship up about 2.5 inches, or 0.15 degrees. There have been concerns that the rocks of the reef on which the Concordia is resting were so embedded in the hull that the ship would resist being pulled off.
“We know that ... she is lively enough to move,” Sloane said.
The operation to bring the ship vertical involves dozens of crank-like pulleys slowly rotating the ship upright at a rate of about 3 yards per hour, using chains that have been looped around its hull. Tanks filled with water on the exposed side of the vessel will also help rotate it upward, using gravity to pull the exposed side down.
Once upright, those tanks — and an equal number that will be fixed on the opposite side — eventually will be filled with air, rather than water, to help float the ship up off the reef so it can be towed away.
Last week, the head of Italy’s Civil Protection agency, Franco Gabrielli, said there was no “Plan B” if the rotation failed since there would be no other way to try again.
