Abstract

The high pressure underground pipelines of industrial states such as Ulsan, Yeosu consist with not only the pipelines for the utility support such as Raw material of petrochemical industry and steam, but also high pressure pipelines of toxic, flammable gas intricately like a web. Therefore, in this study, based on in-depth comparison analysis of industrial estate pipelines, and underground city gas pipelines' safety management status, excavation frequency, excavation depth, patrol period which are pipe damage impact factor by the other construction are analyzed. And, as a result, risk changes and correlations due to risk reduction strategy of the other construction are compared to be presented the safety inspection operation model for the high pressure underground pipelines of industrial estates.

울산, 여수 등 산업단지의 고압매설배관은 주변의 석유화학사의 원료 물질 및 스팀 등 유틸리티 지원을 위해 많은 배관이 매설되어 있음은 물론 독성, 가연성 불활성 가스 등이 고압으로 거미줄처럼 복잡하게 매설되어 공급되고 있다. 이에 산업단지배관과 도시가스 매설배관의 안전 관리 현황을 심층 비교 분석한 것을 바탕으로 타 공사에 의한 배관손상 영향인자인 굴착빈도, 굴착 깊이, 순찰 주기 등을 분석하고, 타 공사 위험감소 전략에 따른 위험변화 및 상관관계를 비교하여 산업단지 고압 매설배관에 대한 안전 점검 운영 모델을 제시한다.
