This paper deals with a novel concept by combining a spar-type floating wind turbine (FWT) and a Torus (donutshaped) point absorber-type wave energy converter (WEC) that is referred as the ‘Spar-Torus Combination’ (STC) herein. Concept feasibility study has been carried out by doing numerical simulations. It showed that the STC results in a positive synergy between wind and wave energy generation in terms of both capital investment and power production. As a novel concept, the STC concept is considered a simple compact combination of two technologies that have had high technology readiness level (TRL). It is suitable for deep water deployment and is not sensitive to seabed conditions and wave directions. Therefore, it is interesting to pursue a further development of this concept. The paper presents the technical information about the STC and highlights some challenging areas of the STC that should be carefully looked at to make it a proven concept.Copyright © 2012 by ASME
