Quantitative assessment framework for seismic resilience of petroleum depots

Abstract

Petroleum depots are an important part of the national strategic reserve base and should maintain functionality during an earthquake or recover immediately after an earthquake; this is known as seismic resilience. To quantify the seismic resilience and functionality of a petroleum depot, a quantitative assessment framework is proposed. First, the influence of the components on the function and seismic resilience is quantified from the perspective of the system by establishing a component–subsystem–system model. Second, the relationship between the damage index and functional loss and the corresponding relationship between recovery time and seismic resilience level are established using functional loss and functional recovery as quantitative indicators. A petroleum depot case study is presented, in which the functional loss and recovery time are explicitly expressed to verify the applicability of the proposed resilience assessment framework. The framework is also applicable to industrial complexes such as chemical plants and refineries, and can help determine the optimal location and design, allowing decision-makers to better formulate emergency and post-earthquake recovery plans.
