Design and Fully Coupled Dynamic Response Analysis of a New Floating Offshore Wind Platform

Floating offshore wind platform (FOWP) has become the economically favored option for supporting turbines in deep waters. It is urgent to propose new concept designs FOWPs that can be effectively deployed. Additionally, extensive use of steel such platforms significantly escalates costs, necessitating optimization utilization. Motivated by these challenges, a V-shaped floating semi-submersible equipped with NREL 5 MW turbine designed and analyzed based on potential flow theory blade element momentum theory. Fully coupled time-domain simulations are conducted using F2A program, which couples FAST ANSYS AQWA via Dynamic Link Library (DLL), compare hydrodynamic performance stability original triangle-shaped model “Fuyao”. Various sea conditions have been considered, including combined wind-wave action wind-wave-current at different incidence angles. The results show better economic (e.g., reduction 40.4% 12.9%, respectively, pitch yaw motions, 17.4% maximum mooring tension), but lower than its counterpart.
