Abstract

Compared with the distribution of onshore and near-shore wind resources, the deep and remote seas exhibit significantly higher wind speeds and richer wind resources, rendering the development of floating wind power in these regions immensely promising. The semi-submersible platform serves as a vital component in the structure of deep-sea floating wind power. However, the motion response generated by traditional semi-submersible platforms under irregular wave loads can lead to an increase in structural fatigue loads on components such as blades and towers, ultimately affecting the wind turbine’s power generation efficiency and system durability. In order to tackle the previously mentioned concerns and challenges, this paper develops a novel multi-body coupled system consisting of moorings, floaters, and a semi-submersible floating platform. This design is based on the traditional DTU 10MW semi-submersible floating platform, with the integration of an array of heave cylinder floater-type wave energy converters. Next, the AQWA software is utilized to model the multi-body coupled system. Based on the hydrodynamic wave theory and the coupled theory of the mooring system, numerical simulation methods are employed to analyze the six degrees of freedom directional motion responses of the multi-body coupled system under realistic irregular wave loads. The numerical simulation result indicates that the array arrangement of heave cylinder buoy-type wave energy converters can effectively reduce the sway, roll, heave, pitch, and yaw displacements of the semi-submersible floating platform. Notably, the suppression rates for sway, roll, and pitch displacements all exceed 50%.
