Redesign of the Fish hold on the Pure Seine 30 Gross Tone Ship as a Safety Device

Abstract

This research aims to redesign the hatch on a 30 GT pure seine fishing vessel made from fiberglass. The hatch is designed using a separate hatch construction system from the ship's construction, so that when the ship has an accident and sinks the hatch can be separated from the ship's rafters and used as a safety device. The method used in this research is the numerical simulation method. The calculations carried out include calculating the volume of the hold, the total weight of the hold construction materials when empty, the maximum capacity of the hold to accommodate caught fish and the buoyancy capacity when the ship's crew (ABK) rests on the hold. The construction calculations used use the Indonesian Classification Bureau (BKI) class calculations which include dividing the distance between the transverse trusses as reinforcement for the hatch walls. The research results show that fish hatches can be used as additional safety equipment on ships using the principle of buoyancy possessed by these hatches.
