Cochin Pipeline Reversal & Conversion

USA & Canada

PROJECT
OVERVIEW

The Cochin Pipeline was originally installed to deliver NGLs from Alberta to Ontario in 1979. When Norwest was approached, our client wanted the ability to deliver natural gasoline (condensate) from Illinois to Fort Saskatchewan. Therefore, Norwest initiated engineering to reverse the flow of a major portion of the pipeline and convert its service from NGLs to condensate. The project required the reversal/conversion of 26 pump stations and 6 tie-ins to existing terminals throughout parts of the US and Canada. Our client was able to deliver condensate on schedule, while Norwest completed project close out services such as as-builting and record book creation.

Added Scope: Based on the success of Norwest’s execution, the client specifically requested we design a new pump station in Canada and a new terminal in Illinois.

Project Deliverables

  • Reversed flow and converted service of the Cochin Pipeline from Illinois to Fort Saskatchewan
  • 26 converted pump stations and 6 terminal tie-ins
  • Structural design & drawings for pump foundations, office building, electrical building, LACT Skid foundations, pipe & cable supports, and platforms
  • Participated in PHAs for every facility along Cochin
  • Construction support, on-site commissioning and startup services, and as-builting
  • Station record books (“The most beautiful record books I’ve ever seen.” – Client PM)

Unique Challenges

  • Largest Project of Norwest’s Tenure: At the time, it was the largest project of Norwest’s tenure. We created a special department of 6 people (PM, engineers, and designers) fully committed to its design and execution.
  • Custom draindown skids: We designed custom skids (26 total) for every pump station. Though FAT was completed; 5 skids did not operate as intended with the existing systems once installed. Norwest went on-site to troubleshoot a solution that could be implemented on skids yet to be fabricated. With the modification developed by Norwest, 21 remaining skids were installed and operated without issue.
  • Norwest’s first project in Canada: We partnered with a lone, Canadian consultant to provide technical support through the project’s earliest phases. It was a cost-effective method to expedite the learning curve of the different nuances between US and Canadian DOT regulations.
  • Record book creation: Originally intended to be completed in-house by our client, time dictated otherwise. Norwest was provided all construction-related documentation for every facility. Hours were spent sifting through contractor notes, weld records, material traceability reports, and non-destructive examination records, in order to compile and develop “the most beautiful record books (our client had) ever seen.”
