A UC Berkeley engineering research team, led by Professor Kenichi Soga, was recently granted $3 million by the California Energy Commission to enhance the seismic risk assessment of natural gas storage and pipeline infrastructure. Over a 3 year period, the team will employ a novel blend of remote and embedded sensing technology alongside advanced data management and analysis techniques for continuous monitoring of gas infrastructure. These methods will be integrated into OpenSRA, an open-source software tool designed for monitoring and risk assessment, enabling predictive modeling and data analytics even in uncertain conditions. Effective utilization of this tool is expected to enhance the safety and resilience of natural gas storage, piping, and infrastructure systems by enabling regulators and owners to focus seismic mitigation efforts on the most vulnerable components.
“The project aims to showcase the practical utility of sensing and monitoring technologies, especially when combined with the open-source seismic risk assessment software tool,” explained Kenichi Soga. “By leveraging cutting-edge sensing and monitoring capabilities with digital twin analyses, this integrated approach will empower utility owners with an enhanced means to assess risks to their systems.”
The work will be conducted by researchers and experts from UC Berkeley, Lawrence Berkeley National Laboratory, Slate Geotechnical Consultants, and the NHERI Computational Modeling and Simulation Center (SimCenter). Cooperating utilities are Southern California Gas Company and Pacific Gas and Electric Company. Support is provided by the Pacific Earthquake Engineering Research Center (PEER).
