Outline
Reliable experimental data are crucial for understanding the performance of Floating Wind Turbine (FWT) systems in complex wind-wave-current marine environments. This paper presents the results from 1∶70 scale model tests conducted in a wave basin to investigate the motion response characteristics of a new 12 MW semi-submersible FWT. The experimental design incorporated improvements, including a large-scale wind generation system with a rectifier network, aiming to provide a stable wind field for the experiment. The experimental results indicate that wind loads primarily exert static effects, as reflected by changes in response mean values. On the other hand, increased wave parameters predominantly contribute to dynamic effects, which are demonstrated through changes in response standard deviations. Aerodynamic damping effect is primarily manifested in the coupling responses of pitch and surge, as well as at the natural frequency of pitch motion. The action of current significantly reduces response at the natural frequency of pitch, although it concurrently amplifies platform’s surge and yaw responses. This study contributes valuable insights into the dynamic behavior of large-scale semi-submersible FWTs under combined wind, wave and current conditions.
