Pipeline Operators have been advised to be able to show traceable, verifiable, and complete records[1] used to establish Maximum Allowable Operating Pressure (MAOP). In instances where this standard of due diligence for confirming historical records cannot be met, other methods of confirming integrity and establishing an MAOP need to be applied. A method and guidance for application of In-Line Inspection (ILI) technologies and/or in ditch non-destructive examination approaches for determining pipe properties, allowing operators to use ILI to meet the requirements and guidelines for confirming that the pipe records are traceable, verifiable, and complete, would provide great value to the pipeline industry.
