In order to predict the self-propulsion quickly, based on the computational fluid dynamics (CFD) method, this paper performed numerical simulation of selfpropulsion for MOERI container ship(KCS) at ship point without rudder and at model point with rudder, in which the propeller was simulated by using a simplified prescribed body-force propeller model to give a model that determined propeller-hull interaction. The method to obtain self-propulsion factors was based on equality thrust method, open water computation and experimental open water curves. A comparison of calculated and measured data shows a fair agreement, indicating that the prescribed body-force propeller model can accurately and quickly predict the selfpropulsion.
