One approach to counteract this has been to use passive damping systems for FOWTs to dissipate the
wave-induced energy and therefore reduce the global platform motions [2]. This paper proposes that
rather than discard this energy, a wave energy converter (WEC) is utilized on the floating platform to
absorb it. This would increase the energy yield of the system and actively reduce the global platform
motions. Another advantage is that these two energy converters have common infrastructure: a possible combination of the wind and wave energy Power Take-Off (PTO) systems; shared electrical grid
connections and shared mooring systems. The progress in identifying optimal damping and stiffness
parameters for two cases (maximum energy extraction and motion reduction) is presented in this paper,
which is as follows: Section 2 describes the system and sea state under investigation; Sections 3 and 4
describe the methodology and choice of WEC parameters; and Sections 6 and 7 outline the simulations
carried out and discuss the results. Finally conclusions about the current work are presented in Section 8.
