Consideration and countermeasures of asset integrity management of oil and gas pipeline networks

With the continuous expansion of China's oil and gas pipeline network, requirements for its safe and reliable operation are enhanced significantly. However, the occasional pipeline accidents and the serious consequences impose unprecedented pressure of safety and environmental protection to the pipeline enterprises. Herein, the status quo of asset integrity management of pipeline network at home and abroad was analyzed systematically, and the current challenges for pipeline network integrity management in China were pointed out. By referring to the advanced experience of asset management of foreign pipelines, and in combination with the existing achievements and the technical basis of domestic pipeline management, measures for the asset integrity management of oil and gas pipeline network were put forward, including performing the key technology research, building a scientific and advanced management system, and establishing a digital and intelligent integrity management mode suitable for the safe and efficient operation of oil and gas pipeline network assets, etc. Moreover, the future development trend and the direction of research were clarified.
