Abstract

This study presents an evaluation method to estimate the damage scale of chemical storage tank of petrochemical plant due to the earthquake that is likely to occur among NaTech damage types. Based on this, the risk for damage reduction of chemical storage tanks was evaluated. As a result of the study, the risk of the storage tank increased greatly considering the earthquake, and the risk was greatly reduced as a result of evaluating the proposed measures to mitigate the damage impact on the earthquake. This study is expected to contribute to the research on the reduction of NaTech damages such as typhoons and thunderstorms as well as earthquakes, and to establish an emergency response plan. In the future, it is necessary to systematically study and institutionalize the risk reduction measures considering earthquakes.

본 연구는 NaTech 피해유형 중 발생 가능성이 높아지고 있는 지진으로 인해 석유화학공장의 화학물질 저장탱크에 미칠 수 있는 피해규모를 도출할 수 있는 평가방법을 제시하였다. 이를 바탕으로 화학물질 저장탱크의 피해저감을 위한 위험을 평가하였다. 연구 결과 저장탱크의 위험도는 지진을 고려했을 때, 크게 증가하였으며, 지진에 대한 피해영향 저감을 위해 제시한 방안들에 대해 평가한 결과 위험도가 크게 감소하였다. 본 연구는 지진뿐만 아니라 태풍, 낙뢰 등 NaTech 피해저감을 위한 연구 및 비상대응계획 수립에 많은 도움이 될 것이다. 향후, 지진을 고려한 위험도 감소 방안에 대한 체계적인 연구와 제도적 보완이 필요하다.
