Impact Of Maintenance Activities On Future Integrity Of Transmission Pipelines

Transmission pipeline companies utilize successive ILI tool runs to identify, size, and determine the corrosion growth rate (CGR) of pipeline features that may be detrimental to the operation of the pipeline [1, 2]. The importance of back-to-back ILI tool runs in monitoring and maintaining the safe operation of a pipeline is further supported by the methodologies’ incorporation by US regulators for high consequence areas. The calculated CGR from the ILI tool runs is used to determine maintenance digs required to mitigate the identified features prior to the next scheduled re-inspection interval.

Transmission pipeline operators regularly inspect their assets using in-line inspection (ILI) tools to monitor for potential internal and external threats to the system. When these tools identify features that meet excavation criteria, the operators will complete mitigation activities to reduce or remove the threat. Typically, these mitigation activities include excavation of the pipeline, removal of the coating, and non-destructive examination at the targeted feature. Upon completion of the maintenance activities, the pipeline is then re-coated and the backfill restored.
