Pipeline Segment-Specific External Corrosion Rate Estimation to Improve Reassessment Interval Accuracy

The primary objective is to provide a simple tool to optimize determination of integrity reassessment intervals by more accurately predicting external corrosion rates that are 1) representative of a specific pipeline segment, 2) include distribution of corrosion rates as a function of location and time (allowing prediction of time-to-first-failure). Secondary objectives include 1) putting recently reported NIST data into a context that can be used by pipeline operators and 2) including the ability to allow reduction of predicted corrosion rate based on close-interval-survey and/or other data.
