摘要：
The design method for equipping the helical spoiler plates on the Spar platform of a floating wind turbine was proposed. The hydrodynamic software AQWA was secondarily developed with FORTRAN programming. The effect of the spoiler spiral arrangement height on the dynamic response of the floating wind turbine Spar platform and the effect of installing mooring buoy on the spoiler platform on the dynamic response and mooring tension of the platform were comparatively analysed. The results show that the radiation damping of the spoiler platform is improved in the direction of surge, heave and pitch, and the surge, heave and pitch response amplitude operators of the spoiler platform are reduced compared with the original platform. Under the coupling action of wind and wave, the spoiler can reduce the surge and pitch responses of the platform and suppress the heave response to some extent. Installation of the spoiler can reduce the rotor thrust, and the platform mooring tension is somewhat increased. The mooring installation of mooring buoy float can effectively reduce the mooring tension and at the same time suppress the platform surge, heave motion responses, while the pitch motion is less affected. © 2023 Chinese Vibration Engineering Society.
