Abstract

Natural gas is an explosive fluid and can cause severe human/material damage when buried high-pressure pipeline is failure, and there have been reported cases of considerable human life damage to actual buried pipeline failure. In domestic cases, the length and duration of pipeline operating are short due to rapid growth. Therefore, it is a fact that the establishment of effective accident data is insufficient for the cause of the accident. In order to systematically construct an accident database, the operation history of natural gas pipeline is longer than domestic, and the cause and frequency analysis of recent natural gas pipeline related accidents occurred in overseas major countries with a long pipeline network was conducted. Then, after grasping the trend of occurrence frequency by incident cause, we tried to establish the foundation for securing the stability of the domestic high-pressure gas transport pipeline network.

천연가스는 폭발성 유체로 고압의 매설 배관 파손시 심각한 인적/물적 손해를 야기할 수 있으며, 최근에도 실제 매설 배관의 파손으로 상당한 인명피해가 발생한 사례가 보고되고 있다. 국내의 경우, 급속한 성장 및 보급에도 불구하고 천연가스 배관의 운영 길이와 운영기간이 짧아 가스배관의 사고원인 등에 대한 유효한 사고데이터의 확립이 부족한 실정이다. 국내에서 사고 사례에 대한 데이터베이스를 체계적으로 구축하기 위하여 국내보다 천연가스 배관의 운용 역사가 길고, 긴 배관망을 갖고 있는 해외 주요국에서 발생한 최근의 천연가스 배관관련 사고의 원인과 빈도를 분석하는 것이 필요하다. 따라서 본 연구에서는 해외 주요국에서 가스배관의 사고원인별 발생 빈도의 추이를 파악한 후 이를 비교 분석하여 국내 고압가스 운송 배관망의 안정성 확보의 토대를 구축하고자 하였다.
