Slurry Pump Box Design & Fabrication

The Project:

Supply (4) Slurry Pump Boxes for Imperial Oil Resources Ventures Limited (IORVL) for Northern Alberta, near Fort McMurray. The scope included design, shop detail, supply, fabrication and assembly of all structural and plate steel, supply and installation of all Chromium Carbide Overlay and AR 400 wear plate and blasting and painting of the exterior. Each Pump Box was 37’-2” long x 24’-6” wide x 18’-10” high and weighed approximately 240,000 lbs for a total weight of about 960,000 lbs.

The Highlights:

  • The project was a design/build so Saskarc’s Project Management Team worked closely with our Engineers to ensure the design met all the project requirements while being fabrication, construction and budget friendly.
  • The shell plates were up to 1-1/4” thick and had ½” on ½” thick chromium carbide overlay (CCO) plate over the majority of the inside surface area, with the remainder of the inside surface area covered with AR 400 wear plate. The liner plates had to be plug welded to the shell, requiring a three layer welding process, inclusive of capping with hard surfacing weld. Welding Data Sheets and procedures were developed for the plug welds for all-position welding, with the overhead corner welds of the liner plates presenting further challenges.
  • A heavy lift hydraulic Jack & Roll system was designed and built to move the Pump Boxes in and out of the fabrication shop, the paint shop and around Saskarc’s yard.
