Abstract: Background:The green ship technologies are gaining in importance in diverse areas of ship design. Objective:To explore the energy-saving and environmentally friendly ship during the primary ship designs stage. Methods:A hull form optimization method based on the full parametric modeling is proposed, in which the Computational Fluid Dynamic (CFD) analysis is integrated, and the algorithms of Sobol and NSGA-II are used. Taking a 674 m3 single trawler as an example, the full parametric modeling of forebody hull form is adopted by employing an F-spline curve with the software CAESES and the total resistance of the full-scale ship is computed by the integrated software SHIPFLOW numerically. Results:It is proved that the presented optimization method can engage well in the automation process of the hull form design under the constraints of displacement and longitudinal center of buoyancy. Compared with the initial hull form, the total resistance of the optimal ship at the design speed of 11.5 kn decreases 12.2%. Conclusions:It indicates that the proposed method of hull form optimization based on full parametric modeling proposed in this paper has better engineering applicability and broad application prospect in practical ship design practices.
