Numerical analysis of coupled sloshing and motion of a cylindrical FPSO in regular waves
In this paper, the coupled sloshing and motion characteristics of a cylindrical floating production storage offloading (CFPSO) are numerically investigated by means of computational fluid dynamics (CFD) tool. The simulations are performed using an in-house CFD solver naoe-FOAM-SJTU which is developed based on OpenFOAM. The active wave generating-absorbing boundary condition (GABC) is utilized for wave generation and absorption. The stabilized k-omega SST turbulence model are used to avoid excessive eddy viscosity near the free surface. CFPSO with and without partially filled liquid tanks in regular waves with different wave periods are simulated and vertical planar motions such as surge, heave and pitch response amplitude operators (RAOs) are compared. Forces due to liquid sloshing and wave loads are extracted and analyzed. The free surface motions inside liquid tanks in one wave period presented to explain the motion characteristics.
