| Summary: | This project is concerend with the analysis and asssesment of the loongitudinal strength of an offshore fishing vessel (Perintis) as a part of ongoing research done by the Marine Technology Group, Universiti Teknologi Malaysia.The primary objective of this project is to establish the safety factor of the main structures of fishing vessel (Perintis) and purpose further improvement on the structural design concerned. The strength analysis was done on several different loading conditions i.e. lightship, hogging load, sagging load and full load are subjected under still water, hogging and sagging wave condition. A simple beam theory was applied for the analysis in which the ship sturcture was treated as a hollow beam consisting of all continuous longitudinal structures. The analysis begins with the determination of weight distribution thorough out the ship length leading to the determination of bending moment, and bending steress value at various stations. Finally, the safety factors of the structure were established. The result indicates that the safety factors of the present vessel structure are smaller than the value required by rules and regulations (Bureau Veritas). A suggestion on the structural scantling is then proposed which could be used for future vessel structural design.
