On Tuesday 9 November, Oma Baatbyggeri AS, in Stord, delivered its newbuilding number 545 «FOB SWATH 10» to the Danish shipping company Offshore Windservice A/S.
Oma Baatbyggeri AS and Offshore Windservice A/S signed the contract for the 32 meter long wind turbine boat in May 2019. The boat is the third in a series of wind turbine boats «Crew Transfer Vessel» that have been delivered to the same shipping company.
The boats are specially designed for transporting service personnel to the offshore wind turbines and have been designed and developed in collaboration with Odfjell Wind AS in Bergen.
The boats can operate in catamaran mode or in SWATH mode (Small Waterline Area Twin Hull) and are designed to give service personnel the best possible comfort and safety.
In catamaran mode, the boat can go at high speed, while rolling and impact are reduced to a minimum due to the large distance from the waterline level and up to the tunnel. This is combined with the use of a stabilising foil system and gives the vessel optimal seaworthiness.
In SWATH mode, the vessel is lowered approx. 1.5 meters in the sea to achieve reduced movements in the sea. This provides a safe transfer of personnel from vessels to wind turbines.
The boats will have a service speed of up to 35 knots and a passenger certificate for up to 55 people and will operate at offshore wind farms throughout the North Sea Basin.
