APPLICATION OF THE SEQUENTIAL UNCONSTRAINED MINIMIZATION TECHNIQUE IN A SYSTEMATIC CONTAINERSHIP DESIGN

This paper investigates the preliminary ship design process. The thesis begins by looking at methodologies for ship design and concludes that a different outlook on the overall process could provide an improvement. In particular, possible modifications were identified in the owner's requirements as traditionally given to the designer. After the new design procedure was developed, effort shifted to implementing the procedure for a containership design. A preliminary ship design model is developed. This model was then used in a test design problem in which an owner desires a single ship to add to an existing trade route. The design model was used to identify acceptable ship alternatives. The determination of attractive designs was accomplished by a version of an optimization method known as a Sequential Unconstrained Minimization Technique. This method employs a barrier penalty function to handle the problem constraints. The search method was found to be effective in identifying design alternatives. In particular, it behaved well with the discontinuities imposed by the discrete engine selections involved with gas turbine power plants.
