Advanced Permanent Remote Pig Tracking

Recent developments in remote inline inspection (ILI) tool-tracking technology have improved the safety of ILI projects by eliminating the need for field technicians to travel to site to witness tool passages. This is particularly advantageous when tracking overnight and through overly difficult to access terrain. One such development is permanent remote ILI tracking. A permanent remote tracking system consists of a series of permanently installed above ground markers (AGMs) that are strategically located to ensure full tracking coverage and monitored 24/7. This paper will explore that the innovative approach PureHM’s partner, Enbridge, has taken to mitigate risk via the installation of a permanent remote tracking system on their Athabasca pipeline network, driving a cost saving of over $4,000,000 over the duration of the 6-year program.
