An optimization approach for fairing of ship hull forms

Ocean Engineering, 2006
This paper presents a numerical fairing procedure to be used at the preliminary design stage to create high-quality ship hull form geometry. The procedure is based on a variational optimization approach in which a fairness measure related to the surface curvature is the objective function to be minimized subject to a set of geometric constraints to ...

Hull form optimization of a cargo ship for reduced drag

Journal of Hydrodynamics, 2016
Hydrodynamic optimization of the hull forms can be realized through the implementation and integration of computational tools that consist of a hydrodynamic module, a hull surface representation and modification module, and an optimization module. In the present paper, a new bulbous bow generation and modification technique has been developed and ...

Hydrodynamic optimization of ship hull forms

Applied Ocean Research, 2001
Abstract An extremely simple CFD tool is used to compare the calm-water drags of a series of hull forms and to define ‘optimized’ monohull ships for which the total (friction+wave) calm-water drag is minimized. The friction drag is estimated using the classical ITTC formula. The wave drag is predicted using the zeroth-order slender-ship approximation.

Automated Knuckle Detection in Ship Hull Forms

Ship Technology Research, 2007
Mesh generation methods for potential flow calculations require appropriate descriptions of the ship hull surface. The IGES standard is a widely used format in the shipbuilding industry for the exchange of ship hull forms. In this paper methods are presented to prepare ship hull form descriptions based on IGES files which are later be used for ...

Geometrical Variation and Distortion of Ship Hull Forms

Marine Technology and SNAME News, 2003
Because of the risk involved with starting the hull form design from scratch, the designer most frequently initiates the hull form design process with a parent form that has satisfactory hydrodynamic performance. Hence, linear and nonlinear variation and distortion techniques have found wide applications in the hull form design studies.
