초록

본 논문은 IMO가 주관하는 공식안전평가 방법의 일부로서 살물선의 화물창 덮개부 수밀 시스템에 적용한 결과이다. 화물창 덮개부 수밀 시스템에 큰 위험을 주는 위해요소는 설계기준을 넘어선 선박의 운항으로 해치 코밍에 고장을 일으키는 것과 빈약한 유지보수와 검사로 인해 수밀 장치에 고장을 일으키는 사고인 것으로 나타났다. 위험해석(risk analysis)을 통해 현재의 경우 한 선박이 1년간 운항하였을 때 약 6만불의 위험이 있다고 계산되었다. 이러한 위험을 감소시키기 위해 제안된 위험통제방안 중 RCO 1(Advanced system directly related to hatchway security)을 적용함으로써 위험을 약 3만불 감소시킬 수 있었다. 또한 비용편익분석을 실시하여 위험통제방안이 비용편익 측면에서도 효과적임을 보였다.

This study was a part of FSA study which was initiated by IMO and was applied to hatchway watertight integrity of bulk carriers. Hazards which were involved in high risk level were identified as follows. Ship Operation out of Design Criteria(Hatch Coaming Damage) and Poor Maintenance & Inspection(Securing Arrangement Damage). The potential risk was calculated by risk analysis and risk control option was made to reduce potential risk. The potential risk was about U$60,000/ship-year and could be reduced to about U$30,000/ship-year by applying RCO 1(Advanced system directly related to Hatchway Security). In addition, effectiveness of RCOs was shown by cost benefit assessment.
