Upgrades to the 2.5 kilometre above-ground pipeline include:
1. Replacing structural bearings
Structural bearings accommodate for movement (lateral and longitudinal) of the pipeline. Bearings near the end of their serviceable life were replaced. Hydraulic lifts and braces were used to take weight off the bearings while new bearings were installed. This work was completed in late 2023.
2. Upgrading access tracks
Upgrades including regrading, concrete work and surface improvements to about 650 metres of access tracks are currently ongoing. This will improve access to the area for ongoing maintenance and inspection work. Completion is scheduled for mid 2024, weather permitting.
3. Improving drainage systems
The pipeline is surrounded by a drainage system to protect the structure and surrounding assets during wet weather events. Upgrades currently underway include repairing and replacing the drainage system above and below ground along the pipeline corridor, cleaning out debris, and scour protection. This work will be completed by mid 2024, weather pemitting.
