摘要：Added resistance in waves is a predominant component for the estimation of ship speed in actual seas, so that it is necessary to be calculated accurately. The added resistance in waves is influenced by the hull form above water line. However it is difficult to take into consideration the form to the calculation theoretically. As a solution to this matter, the hybrid calculation method which combines a result of tank tests with the calculation was developed. The method includes the hull form above water line with the result of tank tests.In order to investigate the effects of the hull form above water line on the basis of the hybrid calculation method, the tank tests was carried out using three types of container ships with the different form above water line. For the expression of the effect of the hull form above water line on the added resistance in waves, a flare bluntness coefficient is installed as a parameter in the hybrid calculation method. The application for the hull form design is studied. The results of the tank tests and the calculation are compared.
