Definition of Geotechnical and Operational Load Effects on Pipeline Anomalies

Main Objective

The objective of this project is to use the previously validated pipe soil interaction model to develop an engineering tool to define the effects of operational and geotechnical loads on liquid and gas pipeline systems to support decision making regarding threat severity or repair scheduling. This tool would be incorporated in strain based design and assessment to facilitate the consideration of complex loading scenarios inducing significant flexural loads, including pipeline subsidence or lowering, and ground movements inducing lateral pipeline movements. The results of this project will define the local nominal strain state that can be used to assess localized anomalies / defects (e.g. corrosion, cracks, dents, weld faults, gouges, etc.).

Public Abstract

The development of an engineering tool will consider the effects of operational and geotechnical loads on liquid and gas pipeline systems to define the local nominal strain state. Localized anomalies/defects or the potential for wrinkle/buckle formation will be assessed to support pipeline integrity decision making or repair scheduling. Using the validated BMT soil-structure interaction model, complex loading scenarios including pipeline subsidence and lateral pipeline movements will be considered. The results of the project will support design and in-service maintenance decisions for geotechnical hazards resulting in improvements in pipeline safety.
