Geohazards and Risk Assessment for Pipeline Route Selection

This chapter on geohazards and risk assessment for pipeline route selection 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 explain some of the scoring systems used for risk assessment for pipeline routes in which numerical values are assigned to conditions on the pipeline system that might contribute to pipe failure. They then describe how quantitative risk assessment (QRA) methods may be used as an improved alternative to the scoring systems, notably to allow appropriate weight to be given to geohazards during the route selection process. Topics discussed include geohazard assessment, including of lateral displacement, spanning, and loading; approaches for estimating the probability of events; consequence assessment and risk estimation; risk evaluation and management; and the use of expert judgment. Seven case examples are provided to illustrate how QRA methods have been used to evaluate the significance of geohazards on a number of recent pipeline projects. These examples all focus on landslides, generally the most important of the geohazards for pipeline routes, although the principles can apply to other hazards such as river bed scour or gullying.
