Observations from ILI false-positives

摘要

In-line inspection (ILI) response can be an expensive program, but one that can have a great benefit to the integrity of pipeline assets. As it can be so costly, it is imperative that all direct examination efforts in response to ILI findings be as beneficial as possible. Excavation of ILI false-positives (i.e., a metal loss anomaly is detected and reported by the ILI, yet upon excavation, no metal loss anomaly is found) can negatively impact the benefits of ILI response programs.
