Study on the application of the safety criteria for standard fishing vessels form for coastal fishing vessels

Abstract

With the recent establishment of the Criteria for Standard Fishing Vessels Form with Reinforced Stability and Welfare noticed by the Ministry of Oceans and Fisheries, fishing vessels with a gross tonnage of less than 10 tons can also be approved for stability. The distance between a ship’s center of gravity and its metacenter (referred to as GM) and the righting arm at the angle of deck edge immersion (referred to as GZ) are used as primary indicators of fishing vessels stability in the stability approval standard of the Fishing Vessels Act and Criteria for Standard Fishing Vessels Form. In this study, K-SHIP software was used to calculate the stability indicators for 25 fishing vessels with a gross tonnage of less than 10 tons and to examine whether the calculated stability indicators achieved the values required by the Criteria for Standard Fishing Vessels Form and the Fishing Vessels Act’s Stability Standard. The GZ requirement of the Criteria for Standard Fishing Vessels Form was always lower than the Fishing Vessels Act, with all 25 fishing vessels meeting the GM and GZ requirements of the Criteria for Standard Fishing Vessels Form, but some failing to meet the criteria of the Fishing Vessels Act.
