API Pipeline, Control Room and Cybernetics Conference

American Petroleum Institute
April 20 to May 20, 2021

The American Petroleum Institute (API) will host its 2021 Pipeline, Control Room and Cybernetics Conference virtually on Tuesdays and Thursday from April 20 to May 20, 2021. Attendees will have the opportunity to participation in and learn about a variety tracks and topics including asset integrity, control room automation, human factors, stakeholder engagement, cybernetics emerging technologies, COIVD-19, and more.

Jeffrey A. Kornuta, Ph.D., P.E., Exponent managing engineer, will present “Statistical Approaches for Validating NDE Predictions of Line Pipe Material Properties” as part of the Asset Integrity track, on Tuesday, April 20, at 12:30 PM PT/3:30 PM ET. Federal rule changes governing pipelines allow operators to use Nondestructive Examination (NDE) technologies to verify pipeline material properties provided that these tools are validated against destructive test results and measurement uncertainty is conservatively accounted for. Measurement uncertainty not only affects the estimation of material properties, but may also propagate to downstream analyses, such as fitness for service and burst pressure calculations. This presentation describes Pacific Gas & Electric Co.'s statistical methodology for the inference of destructive laboratory values from NDE measurements that are collected in the field. The types of material properties that PG&E has evaluated using NDE technologies include microstructure, hardness, chemical composition, and strength. In total, several thousand NDE measurements across approximately 100 pipe features have been evaluated against destructive test results.
