THeoREM facilities involved in the MaRINET2 floating offshore wind Round Robin programme

The MaRINET2 Round Robin program consists in the testing, at IFREMER’s Wave tank, in different European facilities of the same model of floating offshore wind turbine with the objectives of:

• Developing and applying a standardised testing procedure for a floating offshore wind turbine.
• Determining the impact different facilities may have on test results and performing uncertainty analysis.
• Determining the impact of wind action modelling, comparing the use of a thruster with a rotor in a wind field generated by a wind generator.

The first leg conducted at the Ifremer deep wave tank in June 2019 aimed at testing the model equipped with thrusters to simulate the action of the wind on a turbine.

For this second leg, the same 1/60 model of the CENER design of a semi-submersible offshore wind platform is equipped with a rotor developed by the Danish Technical University (DTU) and the wind is simulated using IFREMER’s 12 fans wind generator. Intercomparison of the results obtained simulating the wind using the two different methods will then be conducted.

Complementary tests were conducted in November 2019 at the Kelvin Hydrodynamics Laboratory (University of Strathclyde). Two more campaigns will be conducted at Ecole Centrale de Nantes wave tank and at the LIR National Ocean Test Facility (Cork, Ireland) before summer 2020.
