The purpose of this paper is to develop the simulatIon program of slow drift motions and mooring forces of moored floating structures. The simulation is based on the system functional method (modified Wiener's filtering theory) which is evaluated by using the quadratic transfer function computed from pressure integrals over the instantaneous wetted surface of a floating body. Comparisons between simulated results and experimental ones have been conducted both frequency and time domains, and it has been confirmed that both results are in good agreement while the problem that the added mass and the damping force in still water are modified in waves remains unsolved. Furthermore it has been found from these comparisons that the hydro-dynamic forces acting on the mooring lines should be considered to estimate the mooring forces.
