Two-headed floating offshore wind platform successfully passes test

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.

For one and a half days, we were able to observe how Nezzy² remained stable in the water in extreme weather conditions. Our tests have shown that our model is now ready to be tested in the sea on a full-size scale

states aerodyn managing director Sönke Siegfriedsen. Prior to the test in the Baltic Sea, Nezzy² was tested in a flooded gravel pit in Bremerhaven.

Until now, offshore wind turbines have been anchored to the seabed with solid foundations at a maximum water depth of 50 metres. With floating wind turbines, new countries and sea regions at greater depths can now be considered.

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.
