Main Objective

The goal of this project is to develop and demonstrate a tool that enables operators to make judicious decisions about repairs and re-inspections with regard to pipeline segments affected by SCC. One expected result is a solution that integrates the latest developments in non-destructive evaluation technology and provides a comprehensive, field ready, tool to evaluate, assess and determine repair requirements for SCC.

Public Abstract

Despite various efforts, no reliable tools and techniques exist in the industry that enables an operator to quantify the impact of an SCC (Stress Corrosion Cracking) colony on the safety, integrity and reliability of a pipeline. Furthermore, non-destructive tools for reliable detection and measurement are also not available. This forms a huge gap in the state of the art versus the needs of the pipeline industry. Recent developments in technology promise that given a concentrated effort, various components can be integrated to form a comprehensive solution for the pipeline industry.
This project is the final step in a series of efforts, sponsored by the government and by the industry, to develop a solution to address the complex issue of SCC evaluation in the ditch. Successful completion of this project would lead to the availability of an integrated tool capable of performing remaining strength calculations for SCC as found in pipeline, enabling the operators to make judicious decisions regarding managing SCC on their pipelines, while ensuring safety and reliability in an efficient and practical manner.
