A Process and Matrix for Utilizing Hazard-Resilient Pipelines

A process and matrix are presented for utilizing buried hazard-resilient pipelines. The process and matrix were developed by a group of USA and Japan researchers who worked to improve the understanding of hazard impacts on buried water pipelines. A wide range of natural hazards, many having increased intensity from climate change, are known to affect the performance of buried water pipelines and the ability of water systems to provide services. Hazards impose strains through different mechanisms (e.g., thermal and ground displacement) on pipelines that may lead to damage. Resilient pipelines are beneficial for managing the strains imposed by a wide range of events. The matrix lists hazards and their potential impacts on buried pipelines, service disruptions, and societal consequences. The matrix helps guide pipeline owners to identify, prioritize, and plan for the use of hazard-resilient pipelines. The matrix and an associated process for its implementation into practice are proposed in order to identify the need for and application of hazard-resilient pipelines.
