This study investigated coupling features of wind, wave and tidal current loads and their combined effects on thestructural response of a bottom-fixed monopole supported offshore wind-turbine. A small-scale model of anoffshore wind turbine was developed and systematic laboratory tests were carried out in the Wind-Wave-CurrentTank (WWC) at Newcastle University, UK. In the experiments, the aerodynamic loads in six degrees of freedomof the wind-turbine model were measured. The measurement results have shown that the tidal current and waveshave a significant contribution to the static loads on the wind-turbine model. The dominant frequency of the dragforce acting on the wind-turbine model is the same as the wave frequency. This suggests the natural frequency ofthe wind turbine should be designed far away from the wave frequency to enhance its structural safety.
