UK: Seajacks Provides Construction Update on New Jack-ups
In February 2010 Seajacks entered into a contract with GustoMSC to provide the Basic Design Package for two purpose built wind farm installation vessels.
In June 2010 Seajacks entered into a contract with Lamprell shipyard to build these new vessels and Seajacks will take delivery of the first new-build, Seajacks Zaratan, in May 2012, and the additional new-build shortly thereafter.
These self-propelled jack-ups have been designed specifically to service the wind farm installation market in the harsh operating environment of the North Sea, as well as to provide services to the oil and gas industry. The vessels will be a modified version of the MSC NG5500 design, which incorporates a fully redundant DP2 propulsion system, accommodations for 90 persons, and an 800T leg encircling crane designed by MSC.
