Developing operational resilience within CO₂ utilisation networks: Towards ensuring business continuity through risk management

This study considers the business continuity management system (BCMS) through the development of operational risk management within networks. The objective is to assess the resilience level of a pro-posed CO2 network by evaluating its readiness and capacity to withstand disruptions that can trigger major production and economic losses. Through the incorporation of a resilience index within risk man-agement, this study identifies the critical components, and evaluates network robustness in terms of its ability to withstand disruptions in terms of recovery time. Moreover, the network interdependency be-tween the elements is evaluated by applying the inoperability input-output model (IIM), and dynamic IIM to calculate the recovery behavior of the inoperable components. The outcomes determine that the L-13 and QAFCO -H-2 are the most important factors, while the resilience index is 0.42. Therefore, to enhance resilience index, a CO2 storage is to be located within node 6 serving more than 60% of the sinks. (c) 2022 Elsevier Ltd. All rights reserved.
