초록

일반 상선의 수명연장을 위한 피로해석은 신조선 피로해석과 달리 현재의 부식상태를 고려하고 과거 운항했던 이력 및 향후의 운항 계획을 적용해야 되기 때문에 그 절차가 매우 복잡하다. 본 연구는 신조선 피로해석에 사용되는 완전통계 피로해석법을 이용하여 모스 LNG운반선의 수명연장 과제를 수행한 사례를 소개하고자 한다. 본 논문에서 사용된 기법들과 완전통계 피로해석 프로그램은 향후 수명연장 프로젝트의 피로해석에 사용 가능할 것으로 사료된다.

Fatigue analysis for life extension of a ship is different from that of a newly constructed ship since the current corrosion margin and voyage routes of the past and future must be considered, thereby complicating the life extension procedure. This research introduces the fatigue analysis case for the life extension project of a moss LNG carrier using full spectral fatigue analysis, which has been previously used for newly constructed ships. It is expected that the fatigue analysis methodologies and full spectral fatigue analysis program used in this study will be applicable to other life extension projects.
