INFORMATION TECHNOLOGY FOR RISK-BASED PIPELINE RESOURCE ASSESSMENT

A mathematical model for estimating the resource and efficiency of underground metal pipelines (UMP) based on the use of information technology, quality engineering, and fracture mechanics approaches has been improved. The basis of information technology is the principles of UMP monitoring and the cathodic protection (CP) system. A conceptual model of information technology has been developed to increase the effectiveness of UMP and reduce relevant risks based on UMP and monitoring data, taking into account changes in the state of external surface layers, cracks, and pitting. To optimize information flows in the monitoring system of the gas transportation system, which includes the cathodic protection system, and to improve the anti-corrosion protection system of underground pipelines, the quality function was used, taking into account the inverse relationship and the principles of quality engineering.
