Floating offshore wind turbines experiences motions due to waves and wind that might impact their performances. In this thesis we focus on the effect of surge and pitch on an original design of a counter rotating vertical axis wind turbine (VAWT). For this study, we develop hybrid experimental set up, both in wind tunnel and wave tank, to model the behavior of the VAWT subject to waves and wind. In the tank, the model is submitted to waves when the wind is simulated with the help of a fan controlled by "Software in the Loop" (SiL). The SiL calculates and adjusts the thrust in real-time from the captured motions. In the wind tunnel, the scale-model of the wind turbine is tested when the motions are simulated by actuators. Both approaches highlights the strong interactions between the wind and waves loadings and their combined impacts on the floater behavior and turbine performance.
