Objective Oil and gas storage and transportation facilities are of paramount importance in safeguarding national energy strategic security and meeting the essential needs of people's livelihoods. With the increasing energy demands in China, the expansion of oil and gas storage and transportation facilities within the "One Pipeline Network" is accelerating. Therefore, it is essential to promote the construction and optimization of an emergency response plan system for these facilities within a "One Pipeline Network". This initiative holds significant value in reducing potential incidents, minimizing losses, and maintaining asset integrity.

Methods To provide a comprehensive understanding of the "One Pipeline Network" of oil and gas storage and transportation facilities, the network was categorized into the "One Physical Network" and the "One Intelligent Network" to provide different perspectives. The subsequent analysis focused on identifying and classifying risk events along with their potential consequences within these two networks, resulting in a concise assessment of potential risk incidents across the entire "One Pipeline Network". Building upon this assessment, the study further classified emergency response into various levels for oil and gas storage and transportation facilities within the "One Pipeline Network". Additionally, the study explored various details associated with the development and optimization of an emergency response plan system for these facilities.

Results This study classified potential emergencies of oil and gas storage and transportation facilities within the "One Pipeline Network" into four categories, namely natural disaster emergencies, accidental disaster emergencies, public health emergencies, and social security emergencies. Subsequently, the corresponding emergency response was divided into 4 levels. Based on this classification, an emergency response plan system was proposed for these facilities, specifically incorporating a detailed emergency organization system, emergency reporting procedure, emergency response procedure, and emergency follow-up procedure.

Conclusion The proposed emergency response plan provides clarity regarding the emergency organization and outlines a detailed bottom-up emergency reporting procedure and emergency response procedure.From the perspective of the nationwide network, this study offers an approach to enhance the emergency management system for oil and gas storage and transportation facilities, thereby laying a strong foundation for future emergency digitalization efforts.
