Costa
Concordia’s hull is gradually weakening and might not survive another winter
Giglio Island, Italy: The tiny
Italian island of Giglio made final preparations on Sunday for an unprecedented
attempt to raise the 114,500-ton Costa Concordia cruise ship from its watery
grave.
Salvage workers could be seen
fixing the giant metal chains and cables that will hoist up the 290-metre
(951-foot) wreck, which is roughly the length of three football fields.
The head of the operation, Nick
Sloane, has said it is now or never for the Costa Concordia because the hull is
gradually weakening and might not survive another winter.
The biggest rotation of a
passenger ship ever attempted is due to begin at 7am (4am GMT) on Monday, with
a formal go-ahead based on the weather forecast due later on Sunday.
The project so far has cost more
than €600 million (Dh2.9 billion) and one of the insurance companies picking up
the tab estimates the bill could eventually run to $1.1 billion (Dh4.04 billion).
Scrapping
plans
Once the Costa Concordia is
upright, the plan is to stabilise it and then tow it away for scrapping early
next year.
The ship has been lying on its
side just off Giglio ever since it hit rocks near the shore and keeled over
with 4,229 people from 70 countries on board in January 2012.
The crash sparked a panicked
night-time evacuation. Thirty-two people lost their lives in the disaster.
Using giant cement sacks and a
custom-made metal platform, salvagers have so far secured the rusting hulk,
which was threatening to slip from its resting place into deeper waters.
The plan is to drag it up using
cables and pulleys — a complex operation that environmentalists warn could
spill thousands of tons of toxic waste into the pristine waters.
The hull could bend as it is
being hoisted but the civil protection agency, which is overseeing the salvage,
has ruled out the possibility of the ship splitting in two.
Blocking
traffic
The operation is expected to take
between 10 and 12 hours and all maritime traffic will be blocked in the area,
one of Europe’s biggest marine sanctuaries, until it is over.
The operation holds special
significance for islanders whose lives were turned upside down by the tragedy
and there was a special prayer for the salvage during Sunday mass.
Sloane, the South African who
will be at the controls, said the ship will initially be dragged up for four or
five hours before gravity takes over and it begins to right itself on its own.
Giant metal tanks the size of
11-storey buildings that have been fixed on the side currently exposed are
planned to act as brakes to prevent it from flipping over too far.
The island’s economy depends
hugely on tourism and locals say the presence of the wreck and the massive
salvage operation involving 500 workers has discouraged summer visitors.
Once the roll-over — known as a
“parbuckling” — is completed, workers will weld more tanks or “sponsons” onto
the side of the ship that is currently under water.
Repeated
delays
The salvage operation has been
delayed repeatedly, mainly because of difficulties of drilling into the granite
seabed to install a metal structure to support the ship.
The project is being financed by
insurance for ship owner Costa Crociere, Europe’s biggest cruise operator.
Four crew members and the head of
Costa Crociere’s crisis unit were handed short prison sentences after
negotiating plea bargains over their role in the crash.
The ship’s captain, Francesco
Schettino, is currently on trial accused of manslaughter and abandoning the
luxury liner before all its passengers had been evacuated.
