The Authors discuss the selection of basic characteristics, for a proposed ship, that concern both the ship and its commercial operations, and present guide-lines for determining, in the light of market and traffic conditions, the ship's main dimensions, propulsion system, speed, cargo-handling equipment, and other variables. Such optimisation techniques, developed from an objective viewpoint, are of interest to both the shipping and the shipbuilding industries. The paper, which includes discussions (together with the appropriate graphs) of actual cases studied by Astilleros Espanoles S.A., the Spanish shipbuilders, is presented under the main headings: 1) The Optimisation Concept. 2) The Need for Such Studies. 3) Investment Analysis (General Aspects-Profitability the Criterion). 4) Profitability Calculations (Study of Costs-Study of Revenue). 5) Optimisation Procedure (Propulsion System-Draught-Length and Breadth-Power Requirement-Cargo-Handling Gear-Route-Crew Size-Reduction of Fuel Consumption (in relation to increases in initial cost of ship, as a function of freight rate)-Other Applications (for these techniques).
