The geological structure of the pipeline route area under the jurisdiction of South China company of PipeChina is complex and changeable, the water network is dense along the line. The increasing oil transportation tasks and various external unfavorable safety factors have made it an important and arduous task to ensure the long?term safe, stable and efficient operation of the product oil pipeline. In response to this situation, a set of integrity management system documents and corresponding management platforms suitable for the product oil pipelines had been established, a series of core supporting technologies such as hazard identification and evaluation, monitoring and early warning, inspection evaluation and maintenance decision?making had been development, the long?distance pipeline management model of "system construction + software development + technology research and development" had been explored and applied. Through the application of the company's 6 103 km product oil pipeline, the accident rate has been significantly reduced from 1.04×10^-3 times/(km·a) before implementation to 0.50×10^-3 times/(km·a). The established risk management model provides a strong guarantee for the improvement of the safety management level of the product oil pipeline.
