Pig Tracking

Detect stationary and moving pigs with our developed, tested, and field-proven pig tracking system.

  • Description Description
  • Resources Resources

Frequent pigging of pipeline networks requires control of pig location to avoid collision in pipeline Y-connections. To avoid using radioactive pig-tracking systems, we developed a magnetic pig position and passage sensor. This system can be used both for RFO/commissioning pigging and operational pigging.

Our magnetic pig tracking system is developed, tested, and field proven.


  • Detects stationary and moving pigs
  • Reliable detection; no error-prone calibration necessary
  • Magnetic pig detection; nonintrusive design as preferred for subsea pipeline systems and possible to retrofit
  • Avoids radioactive isotopes, reducing handling costs and eliminating HSE issues
  • Robust and reliable technology qualified for permanent subsea use
