Development of a Commercial Model to Predict Stress Corrosion Cracking Growth Rates in Operating Pipelines

The objective of this proposed project is to develop a crack growth rate (CGR) model for pipeline operators to use to: a) Identify locations that should be given a high priority for assessment of stress corrosion cracking (SCC), and b) Determine the re-assessment and re-inspection intervals. The outcome of this project will be a tool to predict where SCC is most likely to occur, to prevent SCC failures, to ensure continued reliable pipeline operation, and to protect public safety. This project will help to achieve the pipeline operators' goal of zero failures by SCC.
