    Floating Wind Turbines (FWTs) are subjected to wave and wind loads. Coupled wave and wind induced motion response analysis should be performed in the operational conditions in order to investigate the ability of FWTs to produce power. Wind and wave induced motions directly affect the nacelle motion and its velocity which can influence the relative velocity. The magnitude and frequency of platform rigid motions influence the power production and its quality. The present paper deals with the motion responses and power production of moored floating wind turbines in operational environmental conditions. The coupled time domain analysis has been performed for over rated, rated and below rated wind speeds in different sea states. Comparisons have been carried out for wave induced and wave-wind induced responses of parked and operating floating wind turbine. The role of aerodynamic and hydrodynamic damping in different frequency ranges for dynamic motion responses and electrical power production has been investigated. The land based control algorithm implemented but present comparisons are relevant.
