Abstract
The risks of the chemical facilities were estimated by the KS-RBI(Ver. 3.0) program supporting the quantitative cause analysis, and reduction method for the risks of the facilities was investigated. As a result, we could find that the risks of the facilities decrease with reducing the likelihood of failure (LOF) affected by demage mechanism, inspection number and effectiveness of inspection, and with reducing the consequence of failure (COF) affected by the ratings of the detection, isolation, and mitigation systems. Furthermore, high risks of the facilities would be decreased by reduction of the LOF and the COF simultaneously. Accordingly, the applied plant would be able to achieve the decrease of inspection and labor costs because of the decrease of consequences and inspection intervals through the reduction of risks.
정량적 원인분석이 가능한 위험기반검사 프로그램(KS-RBI Ver. 3.0)을 사용하여 화학설비의 위험도를 산출하고, 설비의 위험도를 경감할 수 있는 방안을 모색하였다. 그 결과, 손상메커니즘, 검사횟수 및 검사 유효성을 고려하여 사고발생 가능성(LOF)을 줄이고, 검출, 차단 및 완화 시스템의 수준을 변경하여 사고 피해 크기(COF)를 감소시킴으로써 설비의 위험도를 낮출 수 있었다. 특히, 고 위험도를 낮추기 위해서는 LOF와 COF를 동시에 낮출 수 있는 방안을 모색할 필요가 있으며, 설비의 위험도를 경감함으로써 설비의 안전성 향상으로 사고피해 감소는 물론 검사주기 연장으로 검사비용 및 인건비 절감 등을 기대할 수 있다.
