Rob McPherson & Matthew Dipple: Utilities in Areas of GeoHazards

SaskEnergy owns and operates an extensive natural gas transmission and distribution system in Saskatchewan. A risk-based approach is used by SaskEnergy to manage the potential safety and reliability impacts of slope instability on its infrastructure, and consequently on its customers. This seminar will review some of the solutions that SaskEnergy has worked to develop in concert with external expertise to detect, assess, and mitigate risk to its linear infrastructure in active slope movement areas. The discussion will include the use of varied assessment methods (InSAR satellite monitoring, aerial photos, LiDAR, etc.) and learnings from responding to extreme movement experienced in the Last Mountain Lake area.
