When looking out to the ships in English Bay, one might be surprised to learn just how few are tankers. At present, more than 250 large commercial vessels enter the port each month — about 3,000 per year. Of those 250 per month, only eight are currently destined for Westridge Marine Terminal, five of which are tankers and three are barges. This means traffic to Westridge currently represents less than three per cent of the total traffic in Port Metro Vancouver.
With the proposed expansion of the Trans Mountain Pipeline and associated dock facilities the Westridge Marine Terminal is forecast to serve 37 vessels per month, of which approximately 34 would be tankers and barge traffic remains the same. This increased total would then represent about 14 per cent of today’s marine traffic in Port Metro Vancouver.
The proposed expansion at Westridge Marine Terminal is based on the loading of Aframax tankers, the same tankers currently being loaded at Westridge. Larger tankers are not permitted by Port Metro Vancouver and are not under consideration for the expansion. Proposed changes at the dock include new loading facilities, fire protection, vapour recovery and emergency response equipment.
To connect the Burnaby Terminal with the Westridge Marine Terminal, the proposed expansion includes two new, four-kilometre pipelines each with a diameter of 762 millimetres (30 inches). These two new Westridge delivery lines along with the existing 24-inch delivery line would provide product deliveries to tankers at the three new dock berths that will serve Westridge Marine Terminal, and provide the necessary scheduling flexibility required for loading the planned number of tankers. More details about the expansion can be found here.
TERMPOL Review Process
The Termpol Review Process (TRP) is a voluntary process whereby Trans Mountain conducts a prescribed set of studies, described in Termpol Review Process 2001 (TP743E), and submits these to a Termpol Review Committee chaired by Transport Canada and includes representatives of other federal agencies. The purpose of the review in this case is to assess the safety and risks associated with tanker movements to, from and around Westridge Marine Terminal resulting from the Project. The review includes consideration of:
- Ship design and operation
- Navigational and physical characteristics of the approaches to the terminal
- Terminal design and infrastructure
- Risk and accident analysis along the transit route and at the terminal, and the related mitigating measures
- Pollution prevention program
- Contingency plans
The TERMPOL studies can be found in Volume 8C of the Facilities Application.
The TERMPOL Review Committee report submitted to the National Energy Board on December 11, 2014 can be found on the NEB website.
