New floating offshore wind design gets DNV GL feasibility statement

DNV GL has awarded aerodyn engineering with a statement of feasibility for its double rotor floating wind turbine concept nezzy².

This statement, based on DNV GL’s technology qualification services, confirms that the floater is designed to state-of-the-art safety, quality and performance standards. It allows aerodyn to secure investments and enter the next level of prototype development.

Kim Mørk, Executive Vice President Renewables Certification at DNV GL, says:

“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.“

Mr. Jan-Christoph Hinrichs, Project Manager nezzy² at aerodyn engineering, says:

“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.” 

The innovative floater is designed as 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 MW.
