Abstract
Introduction: Vulnerability introduces the sensitivity of a system versus internal faults or external threats. A vulnerable system cannot recover itself aftershocks and may be disabled to provide services. In this study in order to achieve a resilient city gate station (CGS), vulnerability of the system was identified via SVA procedure. Moreover, using the resilience engineering approach, safety level of a CGS was improved against industrial crises.
Methods: The present cross-sectional descriptive analytical study was conducted in a CGS according to typical design of stations. During this study, SVA procedure, forms and tables were modified and prepared to evaluate vulnerability. In the next stage, the study was conducted in 6 phases according to SVA model and experts panel.
Results: According to the results two industrial crises (explosion / fire and gas pressure drop) were more important than other industrial crises mentioned (regarding adverse effects on the station, the station neighbors and gas consumers). According to this study, the most important assets of CGS station were respectively heater, valves, inlet and outlet and turbine meter and the biggest threat were gas pressure drop and explosion / fire in the station. Finally, regarding the vulnerability scores, 15 solutions were presented to improve the safety level of CGS stations.
Conclusion: SVA modeling in comparison to other methods of risk management such as HAZOP and QRA has a wider vision and in order to conclude the viewpoints, takes into account attractiveness, importance, and system protections and threats as well.
