Abstract

Hydrodynamic analysis of the semi-submersible floating wind system for Phase II of the OC4 project with mooring system is carried out. The simulations are conducted with our in-house solver naoe-FOAM-SJTU based on the open source code OpenFOAM. The finite volume method (FVM) is employed for solving Reynolds-Averaged Navier-Stokes (RANS) equations. The SST κ-ω model is chosen as the turbulence model. The Pressure-Implicit with Splitting of Operations algorithm (PISO) is used to solve the pressure-velocity coupling equation. The impact of the wind turbine is simplified into equivalent forces and moments. The forces and the moments, as well as the motions of the floating system are generated by the naoe-FOAM-SJTU solver. The simulation results are compared with those without mooring system which have been done before. And discussions on the impact of the mooring system are presented.
