In recent years, the offshore wind turbines industry has become more active in response to the movement toward carbon neutrality by 2050, and technological development of large-scale offshore wind turbines with improved power generation efficiency and greater economic efficiency has progressed. However, their response characteristics and the relationship between the scale of power generation and wind turbine response remain largely unknown. In this study, coupled load analyses in wind and waves were performed on fixed-bottom offshore wind turbines with different power generation scales to investigate the differences in the response characteristics of each turbine. As a result, it was found that wind response characteristics are similar between wind turbines of different power generation scales, that wind turbines become structurally more stable against external forces as they become larger, and that the response amplification characteristics due to waves differ between wind turbines of different power generation scales depending on wind response characteristics even under the same wave conditions.
