Eco-friendly installation for wind turbines
Partnership develops environmentally sound system for offshore
In an attempt to combine expertise for the development of a new, environmentally sound concept for offshore wind installation vessels, Wärtsilä and Aker solutions have announced they will work together.
According to the contract, which was inked earlier this year, Wärtsilä will provide the new installation with the ship design, electrical power generation, propulsion machinery and high-end automation, which Aker Solutions is to supply the jacking system.
The cooperation will enable a highly efficient method of setting up offshore wind power generation, with the Wärtsilä dual-fuel engines powering the vessel able to run on liquefied natural gas, and the heat from the cooling system will be used to generate drinking water and hot water for the crew.
Meanwhile, Aker has developed a continous hydraulic jacking system for truss legs, which has been customised for high-performance turbine installation vessels.
The new concept is to be marketed as a complete package, fulfilling the industry’s requirements for large deck space, sufficient crane capacity, year-round and all-weather operational capability and cost-efficient operating systems.
"This new concept is already generating significant interest among that segment of the industry involved with the installation and maintenance of offshore wind farms,” says Riku-Pekka Hägg, vice president, Wärtsilä ship design. “There is a notable demand for a high technology, and fully integrated installation vessel design having significant environmentally sound features.”
