摘要

为计算海上风力机浮体在风、海流、海浪耦合作用下的水动力载荷,探究风、海流如何影响海浪谱、海浪波面和浮体水动力载荷,以及海洋外部环境因素对浮体水动力载荷特征的相关性,建立风、海流影响下的海浪模型。基于风、海浪、海流耦合关系,探究风速、流速增加影响下海浪谱、波面以及水动力载荷的变化趋势。对浮体所受水动力载荷的最大值和极差进行计算,通过随机森林算法,得到海洋环境因素对于浮体水动力载荷相关性的量化结果。研究结果表明,海面风速的增大会增高海浪谱的谱峰,增强海浪震荡;海流流速的增大会降低海浪谱的谱峰,削弱海浪震荡;海面风速和海流速度的增大会引起更大的水动力载荷,是影响水动力载荷最大值和极差的重要因素。

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.
