Abstract

This study evaluates the stability of a 4.99-ton small coastal fishing boat using data interpreted according to the second-generation intact stability criteria of the International Maritime Organization (IMO). The focus is on the ship's behavior under surfriding/broaching conditions during sea navigation, ensuring compliance with international standards. The data processing procedures presented apply stricter criteria than the first-generation intact stability standards to assess the ship's intact stability in waves. However, if the vessel deviates from its standard condition, a separate intact stability assessment based on actual loading conditions is necessary. The surfriding/broaching data processing procedures utilized a program developed by the Shipbuilding and Ocean Equipment Research Center at Kunsan National University. The results were analyzed and compared in detail according to the conditions, parameters, and criteria used for the calculations. Additionally, the study presents the results of Level 1 and Level 2 assessments according to IMO regulations, providing a parametric analysis of the small coastal fishing boat's stability. This allows for the evaluation of intact stability in hydrodynamic motion scenarios.tract.

본 논문은 4.99톤급 소형 연안 어선의 안정성을 평가하기 위해 수집된 데이터를 국제해사기구(IMO) 2세대 비손상 복원성 기준에 따라 해석을 수행하였다. 특히, 해상 항해 중 서프라이딩/브로칭 조건에서의 선박 거동에 중점을 두고 국제 기준에 부합하는 평가 과정을 검증하였고, 제시된 데이터 처리 절차는 파랑 중 선박의 비손상 복원성을 평가하기 위해 1세대 비손상 복원성 기준보다 엄격한 기준을 적용하였다. 그러나, 대상 어선의 상태가 표준 상태에서 벗어나는 경우, 실제 적재 조건에 따라 비손상 복원성 평가가 별도로 수행되어야 한다. 서프라이딩/브로칭 데이터 처리 절차는 국립군산대학교 조선해양기자재연 구센터에서 개발한 프로그램을 사용하였고, 계산이 수행된 조건, 파라미터 및 기준에 따라 그 결과를 상세히 비교 및 분석 하였다. 또한, 국제해사기구(IMO) 규정에 따른 1단계 및 2단계 평가 결과를 제시하여, 소형 연안 어선의 서프라이딩/브로칭 조건에 대한 복원성을 파라메트릭 해석함으로써 유체동역학적 거동 상황에서 비손상 복원성을 평가할 수 있게 되었다.
