A Simple Combined Method for Parametric Generation of Ship Hull Variants

The ship's performance at sea can be influenced by multiple parameters, especially the hull design.Its geometry affects the vessel's behavior, structural integrity, and overall efficiency while crossing the water surface.While the process of hull form generation can involve complex mathematical models, sometimes requiring considerable computational effort, this paper presents a simple method based on the combination of polynomial functions with Lewis mapping techniques.Initially, using a frigate hull as the base model, a code was developed to generate variations of its geometry according to the proposed methodology.Through this approach, it was possible to derive variations of the original hull model, each differing in only one of the considered shape parameters, providing a valuable tool for hull geometry analysis in ship design.
