|Prince Rupert Gas Transmission Pipeline Project Hydrotechnical Water Crossing Designs|
CLIENT: Prince Rupert Gas Transmission Ltd. (Joint Venture led by TransCanada Corp.)
Prince Rupert Gas Transmission Ltd. is developing the Prince Rupert Gas Transmission Project, which proposes the construction of an approximately 800 km long natural gas pipeline across northern British Columbia. The 1220 mm pipeline will cross numerous watercourses, including 73 significant water crossings.
NHC was retained to categorize water crossings and perform a hydrotechnical risk assessment and scour analysis at 45 crossings. Additionally, NHC provided minimum depth of cover and setback design recommendations for the pipeline water crossings.
