Above-ground crossing of the Denali Fault Trans Alaska Pipeline System

Above-ground crossing of the Denali Fault
Trans Alaska Pipeline System

Pipelines are linear infrastructure designed to transport various products. Safe design, construction and operation of pipelines across a range of geologic terrains requires an understanding of interactions between the pipeline, construction and operation activities, and the natural environment. Geological/geotechnical engineering aspects of pipeline projects include route characterization, geohazard assessment, geotechnical quantities estimation, detailed engineering design, mitigation, and monitoring. While the majority of large-diameter pipelines are buried, some segments of pipelines may be built above-ground to cross specific features, such as geologic faults. Examples of pipeline projects in which Dr. Rod Read has been involved are listed below.
