Abstract Two RANS-based CFD approaches were assessed for predicting calm-water towing resistance of the VolturnUS 1:8 semi-submersible floating wind platform. Simulations were performed in FINE™/Marine (ISIS-CFD) using a rigid-lid (RL) single-phase formulation and a free-surface-resolving (FSR) two-phase VOF formulation with quasi-static heave …

Abstract This study investigates the heave and pitch free decay response of a semi-submersible floating offshore wind platform using Computational Fluid Dynamics. Model-scale simulations are performed with a two-phase Navier-Stokes solver, employing a volume-of-fluid free-surface method and a deforming mesh to capture …
