摘要
Floating wind turbines(FWTs) are subjected to combined aerodynamic and hydrodynamic loads varying both in time and amplitude. In this study, a multi-column tension-leg-type FWT(i.e., Wind Star TLP system) is investigated for its global performance under normal operating conditions and when parked. The selected variables are analysed using a fully coupled aero-hydro-servo-elastic time domain simulation tool FAST.Three different loading scenarios(wind only, wave only and both combined) are examined to identify the dominant load influencing each response. The key response variables are obtained and compared with those for an NREL5 MW baseline wind turbine installed on land. The results should aid the detailed design of the Wind Star TLP system.
