Abstract

The development of floating offshore wind farms relies on the efficient design of floating wind turbine platforms. In this paper, we present validations of two-phase flow simulations of the newly developed LIFES50+ OO-Star Wind Floater Semi 10 MW (OO-Star floater) (W. Yu, K. Müller, 2018) using the open source toolbox OpenFOAM. Free decay simulations of the platform are performed and cross-validated against a FAST model (Pegalajar-Jurado, Bredmose, et al., 2018; PegalajarJurado, Madsen, et al., 2018). Further, the forcing on the fixed platform and the loads on the free and moored platform in regular waves are analysed and generally, a very good agreement is seen for the natural frequency, magnitude of
damping and trend of increased damping for larger motion amplitude.
