Construction and application of PipeChina's standard system for asset integrity management in oil and gas storage and transportation

To ensure the advancement, systematic coherence, coordination, and practicality of standards in the field of oil and gas pipeline asset integrity management, 3 698 domestic and international laws, regulations, and standards were analyzed. Through top-level design, multiple standard levels and directions were aligned, and three-dimensional structure and two-dimensional matrix methods were applied to resolve duplication, omissions, and conflicts. A scientific approach for standard formulation and revision planning was then proposed. The results indicated that: ①Through hierarchical planning and dynamic demand matching, a formulation and revision plan for 87 standards—covering pipeline routes, stations, LNG terminals, underground gas storage, and submarine pipelines—was established, completing the asset integrity management standard system for oil and gas storage and transportation. ②By integrating duplicate standards and adopting forward-looking strategies, the system's coherence was enhanced, achieving full-chain coverage from data management to failure response. ③Evaluations of technological maturity and standard applicability recommended prioritizing the revision of outdated standards, strengthening alignment with international standards, and advancing research on applying technologies such as big data and digital twin within the standards. The proposed planning method not only offers a standardized approach for the oil and gas storage and transportation industry but also serves as a methodological reference for developing integrity management standard systems in other infrastructure sectors.
