Abstract: In order to improve the efficiency of pipeline integrity management, a pipeline integrity management system based on the mode of B/S architecture was developed according to the specific requirements and processes of integrity management. Then, a pipeline integrity data model was established and a database was created to realize centralized data management and sharing. The core evaluation modules of this system mainly include high consequence area identification, risk assessment and integrity evaluation. High consequence area identification module is used for the identification, reporting, statistical analysis and updating of high-risk pipe sections. In risk assessment module, the distribution of risk along the whole pipeline is displayed and risk sensitivity analysis is performed. Integrity evaluation module can be used to carry out statistical analysis on internally detected defects (e.g., corrosion, dent and crack), conduct analytical evaluation on externally detected data and provide effective evaluation on anti-corrosion insulation and cathodic protection of pipelines. The pipeline integrity management system based on B/S architecture has been applied in a certain oil pipeline in China. It is shown that this system satisfies basically the integrity management requirements of the pipeline with the advantages of quick response, high reliability and good application results. It provides the basis for safety maintenance decision of pipelines.
