Abstract

A fishing operation is a dangerous and high risk activity. Stability of the vessel plays an important role in performing safely and successfully fishing operations. A brand new 30 GT purse seiner, production of a traditional shipyard in Batang Regency, experienced 15o heel after its launch. This condition potentially affects the stability of the vessel. The purpose of the study is to analyze the vessel stability and improve existing stability by adding outriggers. Research was conducted in two phases, data collection in the research site and stability analysed using a naval architecture software. The vessel stability was analyzed in six loading scenarios following the fishing operation process, subsequently the stability was compared against IMO standard. Results show that with the existing design, the vessel does not meet IMO criteria for the most applied scenarios. Next step, outriggers were added in both sides of the vessel model, as an effort to improve its stability. Accordingly, it is revealed that outriggers addition is scientifically proven to improve the stability of the studied vessel. As this research merely focused on the stability improvement, further analysis regarding maneuverability is required given a purse seiner operates encircled fishing gear. Keywords: outrigger, purse seiner, stability

捕鱼作业是一项危险和高风险的活动。船舶的稳定性对安全、成功地进行捕捞作业起着重要作用。一艘全新的30 GT围网船，由巴塘县一家传统造船厂生产，在下水后经历了150英尺的颠簸。这种情况可能会影响船舶的稳定性。研究的目的是分析船舶的稳定性，并通过增加外伸臂来改善现有的稳定性。研究分两个阶段进行，在研究现场收集数据和使用船舶建筑软件进行稳定性分析。分析了渔船作业过程中6种装载工况下的稳定性，并与IMO标准进行了比较。结果表明，以现有设计，该船在大多数应用场景下不符合IMO标准。下一步，在船舶模型的两侧添加支腿，以提高其稳定性。由此表明，科学地证明了外伸臂的添加可以提高所研究船舶的稳定性。由于本研究仅关注稳定性的改善，因此需要进一步分析围网渔船操作环绕渔具的机动性。关键词:支臂，围网，稳定性
