Offshore wind farm service  and crew transfer.

Most offshore windfarms are located where even average wind speeds are high enough to meet power production requirements. At the same time construction expenses are tried to be kept at a minimum by building in rather shallow waters. But as both strong winds and shallow waters generate higher and sharper waves, you need reliable and stable crew transfer vessels. For this reason, Mobimar has developed the innovative trimaran CTV Mobimar 18 Wind. 

Mobimar 18 Wind provides safer transfers to offshore wind turbines, made possible by the stable trimaran hull and the unique gripper system in the bow. The vessel is classified to seastate Hs 4.0 and as disembarkation is possible in up to Hs 2.5 meters, you get more operational days and less downtime! Not only are the operational costs significantly lower than for most other currently used CTV's due to crew qualification under 750 kW but the fuel consumption is lower as well (linear to the amount of kilowatts). Extra propulsion in the form of two waterjets ensures that the service operation continues even in case of a main engine failure.

A smoother landing

The 180 degree approaching angle allows choosing the most convenient direction according to wind and sea current. The engine can idle during the landing, while the gripper is in either a gripping or sliding mode. This also makes underwater maintenance works at the turbine easier and safer to perform. Due to the trimaran hull characteristics the impact on the platform is much smaller than with corresponding CTV's. The vessel has seats for 12 passengers.

CREW TRANSFER VESSEL

Vessel for the transfer of personnel and spare parts to offshore wind turbines..

Crew transfer vessels (CTV) are mainly used to transport offshore personnel and smaller cargo units. The fender system at the bow helps the vessel to approach the access ladder of a wind turbine or an accommodation vessel and facilitates safe boarding of personnel. Typically, today’s crew transfer vessels are designed to transport 12 people; larger units can transfer 24 people and more. In addition to traditional mono-hull designs, catamarans, trimarans and vessels termed SWATHs (Small Waterplane Area Twin Hull) are deployed in the offshore market. Depending on the specific design, a CTV achieves a speed of between 20 and 30 knots (approx. 50 km/h). Small to medium-sized deck cranes, as well as a fuelling system for wind turbine aggregates add to the versatility of this ship type. Aluminium is the preferred material for the manufacture of crew transfer vessels in order to keep down both their own weight and the impact loads when mooring at the turbine.
