Abstract

The frequency of major accidents which has probability of occurrence at the high pressure underground pipeline of industrial estate such an Ulsan, Yeo-ju by the other construction such as an excavation work will be compared to city gas underground pipeline to derive the basic event by the FTA and present. Also, Observe and analyze the pipe damage impact factor such as an excavation frequency, patrol cycle. As a result, It contributes to the safety improvement of high pressure gas buried pipeline due to obtain importance and sensitivity of the pipe damge impact factors.

울산, 여주 등 산업단지의 고압매설배관에서 발생할 수 있는 굴착공사 등 타 공사로 인한 중대사고의 발생빈도를 도시가스 매설 배관과 비교하여 FTA에 의해 기초사상(Basic event)을 도출하여 제시한다. 또한 굴착빈도, 순찰주기 등 배관손상 영향 인자를 관찰 및 분석하고, 이들 인자의 중요도와 민감도를 Risk 비교분석을 통해 구해봄으로써 고압가스매설배관의 안전성 향상에 기여한다.
