Vattenfall wonders if marine life can settle inside wind turbine foundations

April 7 (Renewables Now) – Swedish utility Vattenfall AB and Dutch nature conservation organization De Rijke Noordzee are conducting research into how and to what extent the interiors of offshore wind turbine foundations can be used by the marine life for settlement and shelter, and as a feeding ground.

The study is carried out on the 1.5 GW Hollandse Kust Zuid (HKZ) wind farm, located 18-34 kilometers from the Dutch coast, between the city of The Hague and Zandvoort. The project applies Nature Inclusive Design (NID) principles, adopting features such as water replenishment holes in the monopiles and rock reefs above the scour protection. These holes allow fish and other marine life to enter and exit again.

Vattenfall noted that this joint study with De Rijke Noordzee marks the first time research has been conducted to determine what water replenishment holes could mean for marine life. Both parties are also joined in this initiative by the Royal Netherlands Institute for Sea Research (NIOZ).

Data will be collected several times over the next two years to monitor the evolution of biodiversity. The first series of measurements was carried out last winter.

“If the results meet our expectations, it will boost marine biodiversity,” commented Erwin Coolen, program director De Rijke Noordzee.

The 140-turbine HKZ offshore wind project is owned by Vattenfall and German chemical company BASF SE (ETR: BAS) and is expected to become operational next year.
