After a review of literature on the computer-aided design of midship sections, with special reference to structural synthesis, the Authors present a structural model for the synthesis of the longitudinal material of the midship section of a bulk carrier. The model is part of a larger one, at present being developed, which will also include the transverse structure, and the main objective is the development of a procedure, applicable to a wide range of ship sizes and cargoes, for the rapid and efficient design of the midship section. In this context, efficient design signifies an optimum combination of advantages in initial cost and cargo capacity. The structural synthesis process and its employment are discussed, including the position of the process in the overall problem of hull-design optimisation. A mathematical model for representing the midship section geometry was developed, together with a method for generating its parameters. Finally, a computer program was developed; some examples of its application, and some conclusions on the influence of design variables on the weight of the longitudinal material, are presented. The program is based on the 1974 Rules of Lloyd's Register. Order from BSRA as No. 49,913.
