Abstract

In the study of semi-submersible Floating Offshore Wind Turbine (FOWT) platforms, a special parameter is the pitch response. Then, with the aim of improving cost-efficiency, a size reduction can be consider. However, the platform cost and size cannot be reduced without consideration of appropriate reduction of the pitch response. Therefore, passive motion reduction surfaces arises as an alternative. A conventional heave plate is designed to reduce the heave platform response, but effects on pitch are also perceived. However, these disks are non-optimal for rotational motion. Then, a novel study of angled disks as a passive rotational motion reduction strategy is conducted. The study was achieved by using two different numerical approaches, potential flow and computational fluid dynamic Reynolds-averaged Navier–Stokes equations.
