Concept design of thin-steel purse seine fishing vessel for enhancing the safety of fishing operations

Despite the continued use of traditional wooden fishing vessels by small-scale fishers in Indonesia, such vessels exhibit inherent limitations in durability, maintenance requirements, and seaworthiness under adverse marine conditions, which directly affect safety and operational efficiency. This study proposes a conceptual design of a 5–8 GT steel-hulled purse seiner fishing vessel constructed using thin steel plates to enhance safety, structural resilience, and sustainability. The research methodology involves the development of a conceptual vessel design with improved resistance to extreme weather conditions, while complying with applicable national and international standards, including classification rules and maritime safety regulations. The design process emphasizes overall vessel configuration, arrangement of main systems, and material selection to achieve efficient and robust construction. The use of thin steel plates is intended to support lightweight construction while maintaining structural strength and durability. The proposed design aims to reduce accident risks and improve operational safety at sea. The results of this study are expected to provide a practical reference for modern fishing vessel design and to support adoption by small- and medium-scale shipyards, contributing to improved safety and sustainability within Indonesian coastal fishing communities.
