Abstract

Hull form optimization is a key technical approach for developing energy-efficient ship hulls. However, selecting appropriate optimization parameters remains challenging. Traditional methods often rely heavily on designer experience, leading to subjective and inconsistent parameter choices. Consequently, optimization results vary significantly and lack generalizability. This study focuses on container ships, using the KCS model to investigate the impact of optimization parameter distribution and hull surface deformation on wave-making resistance. Through systematic analysis, an optimized parameter selection methodology is developed, resulting in significant improvements in wave-making resistance performance for container ships. Specifically, a 20.28% reduction in wave-making resistance and a −3.01% reduction in total resistance are achieved.
