Design optimization of small fishing vessel structures: A case study

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


The cost of vessel operations poses a significant challenge for fishermen in Indonesia, with 60% - 70% of their operational expenses being allocated to fuel. To address this issue and decrease fuel consumption in fishing vessels, one possible solution is to construct lighter boat designs. Through careful optimization of the construction process and the selection of suitable materials, it becomes feasible to achieve such a lighter design, leading to reduced operational and construction costs. The optimization process involves considering various frame spacing variations, like 400 mm, 500 mm, and 600 mm, and utilizing materials such as mild steel and AH32. Additionally, optimizing the plate thickness ensures that the vessel’s stress and deformation remain within the limits set by the rules. As a result of this optimization, a weight reduction of up to 20% is observed.
