Fabricating, transporting and installing North America’s largest-to-date HDPE pipe.

VanPile’s scope of work for the McLoughlin Point Outfall consisted of:

  • Preparation of the Anchor Protection Zone for the HDPE outfall;
  • Micro Tunnel Boring Machine (MTBM) Retrieval and Blind Flange Installation;
  • Installation of the Outfall Pipe: Fabrication and deployment;
  • Installation of the Outfall Armour.

The outfall was fabricated in two segments. Segment 1 (nearshore section) was composed of HDPE DR 21 pipe and was approximately 46.5 m long. Segment 2 (offshore section) was the remaining length of outfall, approximately 1762 m long. Segment 2 was composed of HDPE DR 26 pipe.
For deployment, the pipeline was flooded with the near shore pump system via the PSP. It was submerged under control and stable at all times, as air was released at the offshore end during the process. Once the pipeline was completely flooded and the buoyancy module removed, the Deployment Barge was spooled out on the line and the pipeline lowered to the sea floor at a 65-metre depth. The project was completed on schedule.
