Resistance prediction of trimaran ship in calm water

Abstract

This thesis describes a study about the trimaran ship and the frictional resistance analysis with different side hull ratio and position. A trimaran hull form consists of long slender main hull and two relatively small side hulls. There are a lot of research papers available that investigated the advantages of large trimaran configurations for future cargo ships and alternative frigate/destroyer size warships. There are also several trimaran designs being investigated, which claim both high speed and high hull efficiency. In this study, the author focus on how to reduce the trimaran ship resistance in calm water. In order to achieve that goal, the suitable layout for trimaran ship will be investigate. The layout for trimaran ship are the length of side hulls to the center hull for trimaran ship, the longitudinal position of the side hulls and the distance between the side hulls with the center hull.
