Fully Coupled Analysis of an Integrated Floating Wind-Wave Power Generation Platform in Operational Sea-States

The offshore wind power exploitation has experienced rapid development in recent years and gradually moved into deeper waters with the floating turbine technology getting mature. Due to strong concurrence of wave sites, idea combined utilization by one integrated device attracted tremendous interests worldwide a number concepts designs have been proposed. This article describes novel wind-wave generation platform (FWWP) consisting DeepCwind semi-submersible (FOWT) point absorber energy convertor (PAWEC). Three models including single PAWEC, FOWT, FWWP are considered investigate feasibility its advantages over device. Hydrodynamic analyses first conducted using potential flow code AQWA viscous correction hydrodynamic interactions effect model. Then, fully coupled model for is established calling OpenFAST F2A method. accuracy firstly validated analysing dynamics FOWT. Finally, carried out both regular irregular waves operational sea-states. compared those PAWEC FOWT waves.
