The present study aims to examine the suitability of two commonly used assumptions that simplify modelling metocean conditions for designing offshore wind turbines in the South China Sea(SCS).The first assumption assumes that joint N-year extreme wind and wave events can be independently estimated and subsequently combined.The second one assumes peak wind and waves can be modelled as occurring simultaneously during a tropical cyclone(TC)event.To better understand the potential TC activity,a set of 10000 years synthetic TC events are generated.The wind field model and the Mike 21 spectral wave model are employed to model the TC-induced hazards.Subsequently,the effect of the assumptions is evaluated by analyzing the peak structural response of both monopile and semisubmersible offshore wind turbines during TC events.The results demonstrate that the examined assumptions are generally accu-rate.By assessing the implications of these assumptions,valuable insights are obtained,which can inform and improve the modelling of TC-induced hazards in the SCS region.
