AUXILIARY SHIP HULL FORM DESIGN AND RESISTANCE PREDICTION

Naval Engineers Journal, 1988
ABSTRACTIn this paper 154 auxiliary type monohull designs are analyzed for guidance on how to select the appropriate hull form parameters, particularly with regard to the effects of hull section shapes, sectional area and design waterline curves on ship resistance.

Digitalisation of Small Ships Hull Forms

2006
Rad prikazuje postupak digitalizacije forme trupa malih plovnih objekata. Autori pod digitalizacijom podrazumijevaju pozicioniranje karakterističnog skupa točaka na fizičkom modelu forme trupa broda, ili na već postojećem brodu u pravoj veličini, primjenom digitalne kamere i računalnog programa.

Hull Form Optimization by Shift and Deformation of Ship Sections

Journal of Ship Research, 2001
A technique for reducing ship wave resistance is presented. It is based on a single B-spline patch which approximates the hull surface. A selected specific change of the B-spline coefficients resembles a smooth shift of the ship sections in the longitudinal direction.

Genetic Algorithm In Ship Hull Form Optimization

1999
The paper presents a computational method developed for solving the minimum ship wave resistance problem. The numerical method for solving the three-dimensional potential flow around a ship moving at constant speed in calm water is based upon a Rankine source method.

Ship-hull plate forming of saddle shape by geometrical approach

Journal of Materials Processing Technology, 2013
Abstract In shipbuilding, plate forming is one of the basic manufacturing processes before welding and assembly procedure. It has been practically carried out by line heating method by flame. Since the process depends upon skilled worker's experience, there could be lots of problems in product quality, productivity, working environment and so on ...

Multi-Objective Optimization for Ship Hull Form Design

2009
Hydrodynamic optimization is an important aspect of ship design. The aim of this dissertation is to develop a computational fluid dynamics (CFD)-based computational tool for the hydrodynamic design of ship hull forms. The main components of this hull-form hydrodynamic optimization tool consist of a hull geometry modeling and modification module, an ...

Some Guidance for Hull Form Selection for SWATH Ships

Marine Technology and SNAME News, 1988
Even though in 1987 there were only a dozen SWATH (smali-waterplane-area twin-hull) craft and ships afloat around the world, word of their markedly superior seakeeping performance is spreading rapidly. The number of SWATH vessels is likely to double within five years.
