This paper discusses the practical application of Computational Fluid Dynamics, CFD in ship design. In recent years, CFD has made a great advance in naval hydrodynamics as well as in various other fields. We can estimate the resistance and self-propulsion factors of the limited ship. However, there are some problems to apply the CFD in practical use. The reduction of time of grid generation and computation must be carried out. And actual ships must be represented with calculation grid precisely. The paper describes the method of grid generation that represents a hull from correctly in a short time by the hull surface data in segment form. Then resistance and self-propulsion factors were computed with the double model assumption about VLCC hulls that are actually designed and build in our ship yards. The results of computation with free surface are also discussed.
