The Critical Energy Infrastructure (Cei) Hub: A Look Into The Seismic Fragility Of Oregon’S Fuel, Annecy Bal
The Critical Energy Infrastructure (Cei) Hub: A Look Into The Seismic Fragility Of Oregon’S Fuel, Annecy Bal
Civil and Environmental Engineering Undergraduate Honors Theses
This research evaluates the seismic vulnerability of the Critical Energy Infrastructure (CEI) Hub and the associated fuel repercussions for the expected 9.0 magnitude earthquake along the Cascadia Subduction Zone. The tanks in the CEI hub are analyzed based on size and content. The owners and secondary containment areas are discussed using the same parameters. Various analysis techniques are reviewed to determine the most appropriate seismic fragility estimate for the site. The seismic vulnerability is analyzed using fragility curves by Hazus, American Lifeline Alliance, and D'Amico. The fragility curves are applied to the CEI Hub to determine expected damage and the …
Cei Hub Failure Following A Cascadia Earthquake Event: Preliminary Modeling Of A Liquid Fuel Spill In The Lower Willamette And Columbia Rivers, Mike Du Bose
Civil and Environmental Engineering Undergraduate Honors Theses
The Critical Energy Infrastructure (CEI) Hub in Northwest Portland, OR spans a six-mile stretch of the Lower Willamette River and stores 90% of Oregon’s liquid fuel supply and 100% of the jet fuel for PDX. The CEI Hub is also built entirely on liquefiable soils which are likely to fail during a Cascadia earthquake event. The purpose of this project was to model a liquid fuel spill in the Lower Willamette and Columbia Rivers using the CE-QUAL-W2 model. Several scenarios were developed to account for different environmental conditions, (e.g., high and low discharge years) and varying spill durations (e.g., rapid …
