Land use policies increasingly prevent pipelines from obtaining right-of-way for pipeline corridors that avoid ground movement hazards. Where ground displacement hazards cannot be avoided, the potential risks must be managed by a suitable combination of design and operational strategies.

Land use policies increasingly prevent pipelines from obtaining right-of-way for pipeline corridors that avoid ground movement hazards. Where ground displacement hazards cannot be avoided, the potential risks must be managed by a suitable combination of design and operational strategies. PRCI along with several industry sponsors had a need to make an assessment and provide recommendations for current landslide risk management methods and practices for use within the pipeline industry.Result: The program objective and resulting report developed a comprehensive set of guidelines and recommended practices, in a format that can be implemented within the industry, for evaluating pipelines in areas subjected to large-scale ground movements. The technical program consists of five (5) major project activities related to (1) geohazard definition, (2) improved methods to model pipeline-soil interaction, (3) analyzing pipeline response to geohazards, (4) methods to mitigate pipeline risk posed by geohazards, and (5) compilation of a succinct and complete guidance document that can be readily implemented within the pipeline industryBenefit: This report includes guidelines and recommended practices prepared in cooperation with researchers and operational pipeline owners to minimize integrity risks associated with ground movement hazards.
