Preliminary Design Parameters of Multi-Purpose Cargo Vessels

Abstract

Multi-purpose cargo vessels are intended to carry very dissimilar cargoes (bulk, containers, steel, wood etc.). The paper analyses main parameters to be used in preliminary design of such vessels of range between 88 to 207 m in length. Diagrams and trend lines are presented in order to help designers to choose particulars to design optimum ship characteristics. These parameters include speed, length, breadth, height, draught, displacement, block coefficient, required engine power, gross tonnage and number of containers. Analysis is performed based on comprehensive database of multi-purpose cargo vessels built over the past 30 years. Preliminary design procedure, in general, is explained since this stage (the choice of main dimensions) is most important in determining ship performance.
