In order to achieve energy conservation in actual navigation, based on the Rankine source method of potential flow theory, NSGA-II algorithm is used to study the design of energy-saving ship form in regular waves in this paper. Taking the geometric shapes at the bow and stern waterline of the KCS ship as the optimized design field, the FFD method is used to realize the parametric modeling and geometric reconstruction of the hull. The optimal trim and minimum EEDI are adopted as the objective function. Under the constraint condition of displacement, the NSGA-II algorithm is used to optimize the ship form with the optimal performance. The optimization results show that the wave-making resistance of the optimized ship form is reduced by 39.67% during the optimal trim, which verifies the feasibility of the research method proposed in this paper.
