Mobimar ltd provides crew transfer vessel for offshore wind farms

Mobimar Ltd and Aura Mare Ltd has signed a contract regarding delivery of a new type of trimaran hull vessel, intended for service-crew transfers to offshore wind farms.

 

The vessel to be provided is 18m long and 8,5m wide. The rating of the main engine is approx. 750kW and cruising speed 20 knots. The hull of the vessel is made of aluminum and is ice-strengthened. The accommodation area is spacious for 12 service engineers.

 

Mobimar Ltd has developed trimaran hulls for many years. Except for all the useful experiences we have gained from our previously built trimarans, the hull has also been model-tested in VTT's basin laboratory comparable with open water and in ice conditions. Tests performed by Aker Arctic has revealed  that the hull shape, developed by Mobimar Ltd, breaks the ice with much less power demand than an equivalent sized mono hull ice breaker and still producing a wide and clean channel. Mobimar Ltd has received a world-wide patent for this feature.

 

The benefits of the trimaran hull are: small water resistance, an even and significantly wider work deck area compared with a mono hull vessel of same length, very soft and good sea-keeping properties even in harsh sea conditions. Because of these benefits the vessel is also very suitable for oil recovery, sea surveys and transportation of passengers.

 

At maintenance of offshore wind turbines the transfer from service vessel to the turbine is the most hazardous moment. This far the operations has only been guaranteed to a significant wave height of 1,5 meters. Thanks to the development work at Mobimar Ltd this level has now increased to 2,5 meters, which increases operating days in for example the North Sea with 3 months per year. This also increases profitability for the operators significantly.

 

The vessel will be delivered in the beginning of 2012.
