The floating wind turbine Nezzy² has passed its two-month test in the Bay of Greifswald, Germany. The 18-metre-tall prototype built on a 1:10 scale consists of two wind turbines on a floating platform and is being tested jointly by aerodyn engineering and EnBW.In the Bay of Greifswald, 180 sensors were used in 30 different measurements to establish how Nezzy² behaves when exposed to different wind directions and speeds as well as wave heights and directions. Nezzy² even withstood a storm tide in mid-October. Scaled up to the later true size of Nezzy², the wave and wind conditions were equivalent to a category four to five hurricane with waves reaching heights of up to 30 metres.
The 1:10 scale model has now been dismantled. Over the coming weeks, the recorded data will be evaluated. The findings will then be incorporated in the design of the 1:1 scale model, which is set to be tested in China at the end of 2021 or start of 2022.
