Independent energy consultancy and certification body DNV GL has given its seal of approval to an “innovative” double rotor floating wind turbine concept.
The statement of feasibility, based on the firm’s technology qualification services, confirms that the development is designed to state-of-the-art safety, quality and performance standards.
Designed by German-firm Aerodyn Engineering, the floating wind turbine, dubbed nezzy², is a self-aligning concrete structure attached by single point mooring system to the sea ground.
The two turbines are mounted on a lift and drag optimized, lens shaped, guyed tower structure and will generate a total rated power of 15 megawatts.
This milestone means Aerodyn will now be able to secure investments and enter the next level of prototype development.
Kim Mørk, executive vice president renewables certification at DNV GL, said: “Floating offshore wind will be an exciting new market with 250 GW installed, producing 2% of global power in 2050.
“Qualification of new technology based on state-of-the-art methods and certification schemes linked to international standards is key in bringing early confidence in the concept to this emerging industry“
“Through the cooperation with DNV GL, we have evaluated the technical and commercial risks of the project within the framework of the Technology Qualification. Now we are able to offer our customers a reliable, forward-looking and economically attractive solution confirmed by a statement of feasibility.”
