The Parbuckling Project is the best known wreck removal
project on which SAL has proven its competencies in in-
stallation and decommissioning. With its Type 183 vessels
MV Lone and MV Svenja, SAL installed subsea platforms in
45 metres water depth, as well as several floating sponson
tanks and the blister tank which was essential to stabilize
the bow of the “Costa Concordia”. The heaviest subsea lift
was 1000 tons, the floating sponsons weighed 550 tons,
and the heaviest offshore lift was the bow blister tank of
1500 tons.
