Recommissioning NPS 30 Pipeline

This paper will discuss all the steps taken to reclaim an 80 kilometre (50 Mile) NPS 30 (30″) pipeline loop, including the project planning, the labour requirements, the techniques utilized to complete the various stages of the project, some of the unique problems encountered, as well as, some options that were examined for hydrostatic test leak detection and water treatment.

This project was a component of the Trans Mountain, Cdn $30 million, Stage II capacity expansion. This component of Stage II resulted in an increase of 3,000 m³/d (18,909 barrel/d) to the overall pipeline capacity achieving a 36,300 m³/d sustainable pipeline pumping capacity¹ (230,000 barrel/d).
