ABSTRACT

The recent development of medium-speed monohull passenger ferries has shown their performace for short trips in the maritime countries. The intensive studies of those vessels before aimed to improve the performance of conventional ferries and also to fulfill technical and environmental issues left by the HSC crafts. They operate at the Froude number range of 0.55 to 0.80 which is beyond the hump speed. In fact, they need a high engine power to maintain their operation speeds. The present project is to find the minimum resistance due to the proper dimension of the ship. A base ship of 250 passengers is designed in this study. The variation of seat configurations and passenger distributions, applied in this task, will end-up with the variation of the ship dimensions. Furthermore, those dimensions will affect the performance of the resistance and other ship design parameters. The excel solver is used to solve the problem to find the minimum resistance with the constraints of stability and sea keeping of the ship. The results will be presented and provided for the future study of hull shape optimization, particularly to find the best design of hull form with the minimum power.
