This paper presents the results of a comparison between three In-Line Inspection (ILI) vendor’s high resolution magnetic flux leakage (MFL) inspections. Between 2009 and 2011, Alliance Pipeline Ltd. (Alliance) commissioned the inspection of a number of pipeline segments, where each vendor inspected all segments. These inspections have enabled Alliance to conduct a round-robin comparison of the performance and capabilities of each of the vendor’s abilities to detect and size metal-loss anomalies.
