Stabilit of coastal fishing vessel (B class) in Terengganu based on inclinning and rolling tests

Abstract

This project has been conducted to determine the stability of local fishing vessel ( coastal fishing vessel under B class) in Terengganu. One local fishing vessel under B class designed to operate purse seine net was chosen as a subject. All data on the vessel were collected while it was being refurbish (modified ie. To increase its length and breadth) at repair yard at Kampung Batin, Seberang Takir, Terengganu Darul Iman. First, the lines plan of the vessel were be generated and the displacement of the vessel calculated using the I st of 2 °d Simpsons Rules. The calculated displacement of the vessel was 29.25 metric tons. The GM value of the vessel was determined using Inclining and Rolling Tests. For the Inclining Test, the GM value of the vessel was computed to be 1.30 m and for the Rolling Test the GM value was 1.32 m. There are no significant different between the GM value for Inclining Test and the GM value for the Rolling Test. From these tests, we can conclude that the vessel was stable and safe for operation (based on recommended criteria from IMO which is GM at least 0.35 m).
