Abstract: Considering that ship resistance calculation is needed at the beginning of ship design while the ship type parameters are limited, a 1D ship resistance calculation method is proposed. Considering that it is necessary to carry out fine calculation of ship resistance after the ship type is determined in order to obtain more flow field information or to compare the results with the 1D method, a 3D ship resistance calculation method is proposed. Taking the KCS ship with the real physical tank ship resistance test data as an example, respectively using NavCad based on 1D method and STAR - CCM + based on 3D method to calculate the KCS ship resistance for model-scale and full-scale. Finally, the calculation results of the two methods are compared with the experimental results, and the errors are found to be less than 2%, which verifies the accuracy and feasibility of the two methods.
Key words: full-scale     ship resistance     STAR-CCM+     NavCad     1D method     3D method
