Costa Concordia Salvage Operation Gets OK From Italy
GIGLIO
ISLAND, Italy -- Authorities have given the final go-ahead for a daring
attempt Monday to pull 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.(hd)
The ship
capsized there 20 months ago, and Italy's national Civil Protection
agency waited until sea and weather conditions were forecast for dawn
Monday before giving the OK to try to right it. In a statement 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 70-meter (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 300-meter (985-foot) ship up about 10
centimeters (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 told reporters.
The
operation to bring the ship vertical involves dozens of crank-like
pulleys slowly rotating the ship upright at a rate of about 3 meters
(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. But Sloane said he was confident the ship
would withstand the stress of the rotation.
The most critical time will be the first hour or so of the operation, since that's when the ship will be detached from the reef.
This
weekend, tourists and locals waded and swam in pristine waters just
beyond the harbor, with the hulking wreck an ugly backdrop and reminder
of the harrowing night when a few thousand people straggled ashore.
Since the Concordia came to rest on its side, visitors have come to gawk
at the wreck, providing the tiny fishing island a year-round tourist
season it never had before.
Mayor
Sergio Ortelli has asked for patience from the island's 1,400 residents
during Monday's operation, which he expected would last about 10-12
hours. Ferries linking Giglio to mainland Tuscany stop running at dawn
Monday, meaning teachers for Giglio's two schools were arriving Sunday
night for classes.
Since the
shipwreck, no major pollution has been found in the waters near the
ship. But should the Concordia break apart during the rotation – a
possibility authorities describe as remote – absorbent barriers have
been set in place to catch any leaks. Fuel was siphoned out early in the
salvage operation, but food and human waste are still trapped inside
the partially submerged vessel and might leak out.
As a
precaution, Ortelli told islanders last week that water tanks on the
island would be topped up in case the water supply becomes contaminated.
Other
inconveniences were expected. The island that lives off fishing and
tourism sends its compacted garbage every Monday to the mainland by
boat. That sanitation service will have to be re-scheduled when the port
shuts down for the rotation operation, known in nautical parlance as
''parbuckling."
One of
the last ferries of the day Sunday brought a mix of tourists wanting to
see the boat for what might be the last time on its side and many who
had spent over a year preparing to bring it upright. They included
Franco Ferraiuola, a crane operator who wouldn't be working Monday – he
has some time off – but was bringing his wife to the island to watch the
dramatic attempt.
He
acknowledged that many of the experts were confident they could bring
the ship vertical in one piece but he voiced some concern.
"There is always the unknown. Nothing is certain," he said.
In July,
five Costa employees were convicted in a plea bargain of manslaughter
and sentenced to less than three years apiece. Capt. Francesco
Schettino, whom prosecutors accuse of pulling the Concordia off-course
in a stunt to bring it closer to Giglio, is currently on trial, accused
of manslaughter, causing a shipwreck and leaving the ship before all
passengers and crew were evacuated. He has denied the charges and
insisted the reef wasn't on his nautical charts.
Costa is a division of Miami-based Carnival Corp., the world's largest cruise ship company.
