In-line inspection is a proven technology used by pipeline operators to monitor the integrity of their pipeline. The information provided by the inspection can be used to identify immediate integrity concerns and can be used in the development of long term integrity plans. This paper provides a case history of methods developed and implemented for one pipeline operator to ensure the short-term and long-term integrity of their pipelines. The focus of this paper is the use of high resolution magnetic flux leakage (MFL) inspection tools in the detection, and sizing, and assessment of corrosion-caused metal loss.
