Hydrodynamic Performance of Spar-Type Wind Turbine Platform Combined with Wave Energy Converter

Abstract

In the present study, the numerical investigation of 5 MW spar-type floating offshore wind turbine (FOWT) combined with array of four and six cone–cylindrical shaped heaving type point absorber is performed. Hydrodynamic and multibody analysis is carried out for simple spar, spar combined with circular array of four and six wave energy converters. Individual responses for all wave energy converters are obtained and their effect on spar platform is analyzed. The performance of combined wind and wave energy device is studied on analyzing the motion of platform. The influence of array of wave energy converters on hydrodynamic motion responses on spar platform is analyzed. The Response Amplitude Operator (RAO) for all the three platforms is compared and analyzed for the hydrodynamic stability of platform. The present study will be helpful in the design of novel concept of spar combined with circular array of wave energy converters. © 2021, Springer Nature Singapore Pte Ltd.
