The two companies have selected the best technologies for this custom designed installation vessel, which enables a highly efficient way of setting up offshore wind power generation. The three Wärtsilä 6L34DF and two Wärtsilä 9L20DF dual-fuel engines, that will provide main and auxiliary power for the vessel, can operate on liquefied natural gas (LNG) with low emissions. Similarly, heat from the engine cooling system will be utilized to generate drinking water, and to supply hot water for use by the crew. The accommodation heating on board will also use the same heat source, while absorption chiller units will provide air conditioning during summer months.
