This study is related to improving resistance properties of ships, especially in the high speed range, in which they consume large amount of fuels. In this investigation, the model of the Kriso Container Ship (KCS) was taken as the basis to be studied and she was hydrodynamically analysed through the commercial software STAR-CCM+. After the successful validation of the results obtained in these computational fluid dynamics (CFD) analyses by those of the experiments of this model published in , the simulations carried out on the models equipped with stern flaps and a combination of stern flaps and interceptors for reducing resistance of the models, were performed in the same manner using the same software. Then the results obtained in all analyses were discussed by comparing those with the test ones.
