Comments
Nezzy² is Two wind turbines on a precast concrete floating platform. It is based on a horizontal Y-shaped foundation. This consists mainly of precast prestressed concrete elements that are flooded so that only the three floats and the central tower protrude from the water. The floating foundation self-aligns with the wind direction and is moored by six chains to anchors on the seabed. Two towers rising in Vformation from the centre of the foundation support the two wind turbines. Guy ropes link the towers together and to the foundation. Aerodyn already successfully tested a 1:10-scale predecessor model with a single turbine in the sea off Japan in 2018. Nezzy² has so far been tested on a scale of 1:36 in an artificial wave channel in Cork, Ireland and a 18 metre tall, 1:10-scale prototype is being tested by EnBW and aerodyn engineering in a flooded gravel pit near Bremerhaven. During Summer 2020, pending regulatory approval, a prototype will be installed in the Baltic Sea. It will
