Motion and elastic response of wind-tracing floating offshore wind turbines

Abstract A multi-unit floating offshore wind turbine concept, the wind-tracing turbine, is introduced. In this structure a triangular platform that hosts three 5 MW turbines and moored to seabed with turret-bearing mooring system. This system allows rotate about turret such total yaw moment by environmental load on minimized. study, optimum properties of lines location are determined. To identify preferred turret, responses combined co-directional misaligned wave loads computed. The motions obtained frequency-domain numerical model integrated structural finite-element method for hydroelastic aeroelastic analyses. hydrodynamic aerodynamic diffraction theory steady blade element momentum method, respectively. Finally, configuration system, motion aero- fully flexible waves determined discussed.
