The floating wind turbine has successfully passed the two-month test in the Baltic Sea. With 180 sensors in 30 different measurements it was tested how Nezzy² behaves when exposed to different wind directions and speeds, 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. Even under these extreme weather conditions, Nezzy² remained stable in the water.
The tests have shown that the prototype is now ready to be tested in the sea on a full-size scale. The 1:10 scale model has now been dismantled and the recorded data will be further 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.
