摘要：A novel semi-submersible platform, referred to as HexaSemi, is proposed with a completely new designed heave plate. Compared with WindFloat, the new heave plate has a single hexagonal shape with a moonpool. From the structural point of view, its integral design can increase the integrity of the structure. In this paper, we mainly study its hydrodynamic performance for offshore wind turbine. A numerical model is set up to simulate the motion characteristics of the floating wind turbine system, based on WADAM, Star-CCM+ and FAST. The comparative analysis of HexaSemi and WindFloat under the storm condition is conducted and discussed. It is found that the integral design can increase the viscous hydrodynamic damping, reduce the motion response, and reduce the mooring cable force.
