The event took place on 20 June with more than 100 people visiting the facility to see the latest developments in floating wind being put to the test.

The 1:60 scale model tests are carried out using DTU’s 10MW scale model pitch-controlled wind turbine, and two floater configurations are considered. The floating wind turbine is subjected to wind and wave forcing for a number of operational and survival conditions.

The objectives of the model test campaign are to provide a proof-of-concept of the TetraSpar foundation as well as advance experimental testing and data analysis techniques in this area.

Henrik Stiesdal is a Danish inventor and former Chief Technology Officer at Siemens Wind Power who has worked with wind energy technologies since the later 1970s.
