Oil and natural gas pipeline network systems are critical national and transnational energy transportation infrastructures, serving as the core lifeline of energy security, supporting industrial production, domestic energy supply and stable socio-economic operation, with irreplaceable importance in the global energy supply chain. Long-term operation in complex and harsh environments exposes these systems to multi-source threats, including geological disasters, extreme weather, corrosion and aging, third-party damage, and cyber security attacks brought by the digital transformation of pipeline systems. These threats may not only cause sudden accidents such as pipeline leakage and explosion, but also trigger cascading failures of the interconnected network, resulting in severe casualties, environmental pollution and regional energy supply disruptions. In this context, traditional reliability analysis and risk assessment methods can hardly fully cover the dynamic evolution of multi-source coupled hazards, and the full-life cycle resilience management of pipeline systems faces new challenges, calling for proper addressing of the convergence of safety and security concerns to ensure the disaster- and attack-resilient operation of oil and natural gas pipeline network systems.
