Abstract

This study conducts an in-depth analysis of the dynamic response characteristics of a novel Triple-Spar floating wind turbine platform, which integrates the advantages of both semi-submersible and Spar-type platforms, under the environmental conditions of the floating wind farm in Wanning, Hainan, China. Using the commercial software ANSYS AQWA, a numerical model of the floating wind turbine was developed to systematically investigate the effects of combined wind, wave, and current forces on the mooring system and platform motion response under both uniform and shear flow conditions. The results indicate that, under the environmental conditions of the South China Sea wind farm, the Triple-Spar platform demonstrates excellent motion performance in the heave direction. However, the presence of shear flow induces significant variations in the heave and pitch responses, posing new challenges to platform stability and safety. This study provides valuable theoretical insights and data support for the design and operation of offshore wind farms in China.
