Huisman wins DEME jack-up contract
The jack-up vessel, Sea Installer, will be deployed in the US wind farm Vineyard Wind 1
Netherlands-based Huisman, a heavy lift and construction equipment specialist, has won a contract from marine engineering firm, DEME, to supply a 1,600-tonne Leg Encircling Crane (LEC) for its jack-up vessel, Sea Installer.
The new crane, with lifting capacity 700 tonnes greater than the Sea Installer’s existing equipment, will enable the vessel to handle the latest series of offshore wind turbines, including 800-MW units for the Vineyard Wind 1 offshore wind farm in the United States.
The LEC, which will be supplied from Huisman’s Schiedam plant, will have a 140m-long boom and be able to reach almost 160m above the main deck, the company said.
Other features of the electrically-driven system include high position accuracy with a slew bearing system developed by the company, a lightweight boom designed to reduce motion at the crane tip, and a small tail swing to maximise use of deck space.
