Trimaran crew transfer vessel increases offshore wind farm access window

Mobimar Ltd is building a trimaran crew transfer vessel for Meriaura Ltd, which could extend the access window to offshore wind farms by three months every year.

The offshore wind farm crew transfer vessel, Mobimar 18 Wind, is set to be finished in March 2012.

The three slim hulls keeps the vessel stable even in harsh weather conditions with significant wave heights up to 2.5 m.

“The Mobimar 18 Wind truly meets the demands of the wind farm industry. It is classified to seastate 4.0 Hs , and provides safe transfers for service engineers in significant wave heights up to 2,5 m,” says Pauli Immonen, Managing Director of Mobimar Ltd.

The vessel has an intelligent gripper system in the bow, enabling it to approach offshore wind turbines from either side and run idle during disembarkation. The hydraulics keep the landing platform in position and the water jets in the side hulls make the vessel easily manoeuvred.

The Mobimar 18 Wind trimaran vessel is also said to be much less sensitive for rolling and slamming than monohulls and catamarans.

The offshore wind farm crew transfer vessel measures 18 m in length and the beam is 8.5 m. The large deck space can be used for transport of maintenance equipment and as a workspace for work that cannot be carried out at the wind turbines.

Mobimar 18 Wind is designed and built by Mobimar Ltd. in Turku, Finland and will be classed by Bureau Veritas, DNV or equivalent.
