The present paper deals with the development of a multi-purpose floating tension leg platform (TLP) concept suitable for combined offshore wind and wave energy resources exploitation, taking into account prevailing environmental conditions at selected locations along European coastline. examined Renewable Energy Multi-Purpose Floating Offshore System (REFOS) encompasses an array hydrodynamically interacting oscillating water column (OWC) devices, moored through tensioned tethers as TLP supporting 10 MW turbine (WT). system consists triangular supported by cylindrical floaters, WT mounted deck’s center OWC devices its corners. Details modelling are discussed hydro-aero-elastic coupling between floater; mooring system; is presented. analysis incorporates solutions diffraction; motion- pressure-dependent radiation problems around structure, aerodynamics integrated design approach validated extensive experimental hydrodynamic scaled-down model tests. verified theoretical results attest to importance loading characteristics on dynamics system.
