Twinning the Trans Mountain Pipeline system requires more storage tank capacity and pump stations along the route. We’re focused on expanding existing facilities and reducing the need for extra land.
Pump Stations
Pump stations contain electric motors that drive the pumps to maintain the pressure and flow rate in the pipeline. To support the expanded pipeline system, we’re adding 11 new pump stations along the route and one new pump station will be added on the existing pipeline. Ten of the new pump stations will be added at existing facilities. This means we need only one new site in BC to include a pump station for both the existing and new pipeline.
Terminals
To accommodate the increased capacity of the pipeline system, we’re adding new storage tanks at existing Trans Mountain terminals. All additions will take place within the existing footprint of the terminals, so we don’t need additional land.. All tanks will be constructed in accordance with API Standard 650 - Welded Tanks for Oil Storage.
