Research status and prospect of comprehensive pipeline transportation system under intelligent multi-network integration

ObjectiveAgainst the strategic backdrop of China’s efforts to build a modern, high-quality comprehensive three-dimensional transportation network and a new energy system, the pipeline transportation system—core to efficient cross-regional transport of energy and strategic materials—is undergoing a critical transformation from a traditional single-medium facility to a hub infrastructure featuring intelligent multi-network integration of “pipeline-transportation-energy”. MethodsA combination of policy document analysis, literature review, and case investigations was employed. The core concepts and driving factors of intelligent multi-network integration were thoroughly analyzed, and the pipeline transportation system’s central role in three strategic goals—constructing a comprehensive three-dimensional transportation network, advancing the energy Internet, and enhancing national energy security and resilience—was systematically explained. ResultsAlthough national top-level plans for multi-network integration have been issued and initial progress achieved in some hub and intermodal scenarios, current efforts largely remain limited to physical connections or superficial coordination between networks. Deep intelligent integration—characterized by data interconnection, functional complementarity, and mutual benefits—has yet to be realized. Therefore, it is further emphasized that the primary task now is to translate the strategic vision into actionable, operational, and binding plans. The development requirements and core challenges for the comprehensive pipeline transportation system are identified across three dimensions: fundamental integrated element design, infrastructure digitalization support, and advanced intelligent transportation services. ConclusionTo develop an intelligent, green, and resilient comprehensive pipeline transportation system and support the national comprehensive three-dimensional transportation network and new energy system, the following recommendations are proposed: (1) Strengthen collaborative planning by establishing a “multi-energy supply-demand and multi-transport capacity” mechanism to address mismatches between energy sources and loads, while balancing normal efficiency and emergency supply security. (2) Enhance transportation and dispatching efficiency by advancing multi-energy coupling simulation and optimization algorithms, enabling precise resource allocation through market mechanisms. (3) Improve system resilience by implementing a full life-cycle evaluation framework, developing an emergency response system combining “immediate response and proactive prevention”, mitigating cross-system risk transmission, and ensuring a stable energy supply for both military and civilian needs.
