ASL successfully completes metocean survey off Canada’s west coast
ASL recently finalized a six-month metocean survey for FortisBC Energy. This survey is part of ongoing operations and maintenance efforts supporting the Vancouver Island Transmission System, which supplies natural gas to Vancouver Island and the Sunshine Coast. Wave buoys and subsea current profilers were deployed from December 2023 to June 2024, with a mid-programme servicing trip in March 2024. All subsea equipment and wave buoy mooring anchors were successfully recovered, with full recovery of all datasets.
The field programme measured directional waves and subsea currents at six individual moorings deployed at three strategic locations along the pipeline route in the Strait of Georgia near Powell River, BC, and Texada Island. These measurements utilized ASL’s new PBM-15 polyethylene deepwater buoys to support data collection in water depths of up to 400 metres. The datasets collected from this programme will be used in numerical modelling studies to support pipeline spanning and integrity assessment at various locations, to be conducted by Worley and RPS, a Tetra Tech Company.
The Vancouver Island Transmission System is a critical energy infrastructure that transports natural gas from the British Columbia mainland to Vancouver Island. This pipeline system ensures a reliable natural gas supply to the island’s residents and industries, supporting residential heating and electricity generation. ASL supports preliminary front-end engineering design (PRE-FEED), construction, and operations and maintenance assessments for new and existing marine energy infrastructure.
