Abstract

This study was conducted with the purpose of preparing an alternative to improving the safety of civil pressure regulators installed instead of gas governors to supply city gas to apartment houses. First, problems were derived and solutions were presented by investigating the safety standards and installation status of domestic pressure regulators. In addition, using the DNV Phast-Safeti program, a quantitative risk assessment solution, risks such as gas leakage contained in pressure regulators installed in apartment houses and surrounding gas facilities were evaluated in terms of individual risks and societal risks, and measures were derived to reduce the risks in the installation and management of the pressure regulators.

본 연구는 공동주택에 도시가스를 공급하기 위해 정압기 대신 설치하는 공용 압력조정기의 안전성 향상을 위한 대안을 마련하기 위한 목적으로 진행되었다. 먼저, 국내 압력조정기의 안전기준 및 설치 실태를 조사하여 문제점을 도출하고 해결방안을 제시하였다. 또한 정량적 위험성평가 솔루션인 DNV Phast-Safeti 프로그램을 이용해 공동주택에 설치되는 압력조정기와 주변 가스설비에 내포된 가스누출 등의 위험성을 개인적 위험도와 사회적 위험도로 구분하여 평가하고, 압력조정기의 설치와 관리 측면에서 위험성 감소를 위한 방안을 도출하였다.
