API-581에 의한 정량적 위험기반검사에서 탄소강 및 저합금강의 외부부식에 치한 사고발생 가능성 해석
Analysis of Likelihood of Failure for the External Corrosion of Carbon and Low Alloy Steels through the Quantitative Risk Based Inspection using API-581
Likelihood of failure for the external corrosion of carbon and low alloy steels, which affect to a risk of facilities, was analyzed quantitatively through the risk based inspection using API-581 BRD. We found that the technical module subfactor (TMSF) decreased as the inspection number increased and it increased as the Inspection effectiveness and the used year increased. In this condition, the TMSF showed high value for the case of the marine/cooling tower drift area as a corrosion driver, poor quality of coating, no insulation, and low insulation condition.
