Selection of Main Dimensions and Calculation of Basic Ship Design Values

Abstract

This chapter deals with the determination of the main ship dimensions (length, beam, draft, side depth), following the estimation of the ship’s displacement and the selection of other basic ship design quantities and hull form characteristics (hull form coefficients, powering, weight components, stability and trim, free- board, load line), as required in the first phase of ship design, that is, the Concept Design. The various effects of specific selections of ship’s main dimensions etc. on the ship’s hydrodynamic performance, stability and trim, structural weight and construction cost, utilization of spaces, and transport economy are elaborated. The selection procedure is supported by statistical data and empirical design formulas, design tables and diagrams allowing direct applications to individual ship designs. Additional reference material is given in Appendix A.
