The
Titan-Micoperi
consortium named by
Italian cruise line
Costa Crociere to
remove the wreck of the
Costa Concordia has
reached an agreement
worth “tens of millions
of euros” with Italian
shipbuilder Fincantieri
to build 30 steel
caissons to help refloat
the ship, according to
Costa. The caissons,
which are massive
watertight boxes, weigh
a combined 11,500 tons
and will be built in
several Fincantieri
shipyards. They will be
used to right and
refloat the vessel,
allowing it to be
removed in one piece.
After
the sunken ship has been
stabilized, caissons
will be attached to the
upper side of the hull
and gradually filled
with water. The ship
will then be righted
through the use of
“strand jacks” -- a
hydraulic mechanism for
pulling cables - fixed
to an undersea platform.
When the ship is
upright, water-filled
caissons will be fixed
to the hull’s other
side. The caissons on
both sides will then be
emptied to refloat the
wreck. Once afloat, the
Costa Concordia wreck
will be towed to an
Italian port.
Preliminary work to
prepare the wreck for
salvage is proceeding on
schedule on Giglio
Island, according to
Costa. Costa workers are
also inspecting the
seabed regularly, and a
site clean-up operation
devised to conserve the
marine environment will
be the company’s main
focus once the wreck has
been removed. The
preliminary stage is
expected to be complete
by the end of July and
will be followed by the
ship-stabilization
phase.
