Abstract

To calculate the hydrodynamic loads on floating offshore wind turbine （FOWT） platforms under coupled wind-current-wave interactions and investigate how wind and currents influence wave spectra, wave elevations, and hydrodynamic load characteristics, this study establishes a coupled wind-current-wave interaction model. The model systematically explores the evolution trends of wave spectra, wave surfaces, and hydrodynamic loads under increasing wind speeds and current velocities. Maximum hydrodynamic loads and load ranges are calculated, with the Random Forest algorithm employed to evaluate the correlation between marine environmental factors and hydrodynamic load characteristics. Key findings include： Increasing wind speed amplifies wave spectral peaks and intensifies wave oscillations; Stronger currents suppress wave spectral peaks and dampen wave oscillations; Both elevated wind speeds and current velocities increase hydrodynamic load magnitudes, and are important factors affecting the maximum and range of the hydrodynamic loads. This research provides a data-driven framework for coupled environmental load analysis, offering insights for FOWT platform design and survivability assessments in complex marine conditions.
