Key Elements of an Integrity Management Program for Pipelines to Achieve Consistent Reliability

This paper describes mosaic complex of analytical issues developed to ensure integrity management of main (transmission) pipelines. The following applications of analytical supporting (incorporated by integrity management scheme) are considered: probabilistic analysis of ILI data; corrosion growth evaluations; strength assessments of damaged pipes; procedure of defect ranging; strength recovery by wrap repairs; remaining life and reliability assessments; optimization of maintenance strategy.
