SeaJacks, the company specialized in providing transportation and installation services for the offshore wind industry, is planning to build two or more new jack-up vessels. So far, SeaJacks has two such ships in its fleet, SeaJacks Lieviathan and SeaJacks Kraken, both already quite busy at various offshore wind projects. The company has recently been acquired by Riverstone Holdings, and much of the funding for the expansion of SeaJacks' fleet is coming from the renewable energy fund.

The new vessels will be modified versions of the existing models, with the fully redundant DP2 propulsion system. They will be able to accommodate about 90 persons, and will feature an 800 ton leg encircling crane. SeaJacks has contracted GustoMSC to develop the Basic Design Package, prior the a final decision on the shipyard where the ships are to be built. This will ensure the delivery schedule for the new vessels is maintained. The first one is expected to be completed in Q1 2012.
