Construction activities are currently underway at Westridge Marine Terminal. Preparation work to build the new three-berth dock complex began in September 2017, with the installation of the marine safety boom. Crews have also started work on the foreshore construction program including riprap removal activities.

Construction equipment, barges and supply vessels have been deployed to the site and the turbidity curtain has been installed to protect the marine environment during in-water excavation operations.

Before the foreshore construction can begin, crews have to first remove the riprap along the shore. In accordance with NEB Condition 81, we’ve developed a Marine Water Quality Management Plan, including mitigation and monitoring measures to protect water quality during riprap removal.

A critical piece of equipment being used on-site is the D.B. General, the largest revolving derrick barge on the West Coast of North America. Aboard the D.B. General is the MENCK hammer that will be used to install in-water piles.

Trans Mountain is taking an innovative approach to help reduce potential noise from pile driving activities. Our Lower Mainland Contractor, KLTP, will be using ‘noise shrouds’ to cover the hammers that drive piles, which is required as part of construction for the new marine terminal. The shrouds, which are about two stories tall and wide enough to hold a medium-sized SUV, are expected to dampen the sound of hammer impact by 65 to 95 per cent.

In addition, an underwater bubble curtain will be used to reduce the pile driving noise beneath the surface of the water, in accordance with the comprehensive Environmental Protection Plan and Noise Management Plan for Westridge. 

During construction at Westridge Marine Terminal, which is expected to continue until 2020, our current tanker loading operations will continue. We’ll regularly communicate and update all marine waterway users through a variety of methods, and continue to share new information with our neighbours and address questions and concerns.

As part of NEB Condition 48, we’ve developed a Navigation and Navigation Safety Plan to manage and mitigate the marine impacts of construction. In order to protect workers and marine waterway users in the area, the work area is defined by a floating construction safety boom, which is marked with appropriate navigation lighting and controls.

Marine waterway users are encouraged to take extra caution when nearing the area and to familiarize themselves with safety protocols while on the water. Large commercial vessels navigating the area will continue to follow the well-established vessel movement practices under pilotage.
