Seismic Assessment of Pipelines

Highlights of SGH's analyses include the following:

• Determined seismic hazard of the site utilizing site-specific seismic ground motion studies and geotechnical reports
• Evaluated seismic risk using calculations to compute the effect of wave propagation on the straight segments of the pipeline, horizontal and vertical bends, and vertical risers
• Considered items, such as seismic-induced soil subsidence, liquefaction, differential ground motion from seismic wave propagation, and connection to structures supported by piles
• Performed detailed evaluations of the underground pipelines
