When precise measurements for verification of the remaining wall thickness of jet fuel lines running from bulk storage tanks at an offloading terminal to storage tanks at an airport terminal were required Dexon’s ultrasonic intelligent pigging system was put into action.

The lines were 8” in diameter and 22km and 3.5kms in length. There were further challenges as one line had an obstruction that was identified during a foam pig cleaning run. After assessing the obstruction using our progressive pigging system we were able to recommend running the intelligent pig.

The expertise and experience of our team was critical in the successful completion of the work as the obstruction did not impede the intelligent pig and complete data was acquired without incident. After assessing the data on site recommendations were made to allow for continued safe use of the lines.
