Performance evaluation method of oil and gas pipeline integrity management

The performance evaluation of integrity management has become the focus of attention because integrity management has become widely accepted by pipeline operators. This paper proposes a three-index system of pipeline integrity management performance evaluation (TISPIMPE), which includes system construction, implementation process, and pipeline health status, comprehensively evaluating the status, adequacy, and effectiveness of integrity management. It helps the pipeline operators to determine the weakness in each step. Based on the improved analytic hierarchy process (AHP), the different backgrounds of experts are fully considered, and experts' opinions are revised. The adjustment coefficient of performance evaluation is set up simultaneously, and the evaluation results are adjusted to make the results more reasonable. Taking the per-formance evaluation of pipeline integrity management of an oil and gas company as an example, it is shown that TISPIMPE has reasonable practicability and can accurately reflect the shortcomings of pipeline integrity man-agement. TISPIMPE can effectively help pipeline managers comprehensively and systematically evaluate the performance of pipeline integrity management and gain an in-depth understanding of pipeline operation status.

This paper proposes a three-index system for the performance evaluation of pipeline integrity management. It comprehensively evaluates the status, adequacy, and effectiveness of integrity management, helping pipeline operators identify weaknesses in each step. The improved analytic hierarchy process is used to consider different expert backgrounds and revise their opinions. The evaluation results are adjusted to improve their reasonableness. The case study of an oil and gas company shows that the system has practicality and accurately reflects the shortcomings of pipeline integrity management, providing a comprehensive understanding of pipeline operation status.
