Pipelines and Landslides in Rugged Terrain: A Database, Historic Risks and Pipeline Vulnerability

This chapter on pipelines and landslides in rugged terrain is from the proceedings of an international conference on the terrain and geohazard challenges facing onshore oil and gas pipelines (June 2004, London, United Kingdom). The authors note that although landslides offer a major threat to pipelines in rugged terrain worldwide, there is little published information available. In this chapter, they present a database of landslide-induced pipeline ruptures in the terrain of the Colombian Andes. Much of the pipelines in the Colombian Andes predates the close collaboration of pipeline and geoengineering specialists, so there is a rich history of landslide-induced pipeline ruptures. The authors discuss the lessons learned from these ruptures and put this experience into a broader international context of the risk of landslide induced pipeline spills. They offer information to aid understanding of failure frequencies, triggers, failure modes, and routing strategy. A simple model is proposed to explain the scale of landslide and soil properties, which will damage a pipeline of given diameter, wall thickness, and steel strength. The model reflects the observed failure modes, and is seen to fit well with the cases in the database.
