The Department of Transportation (DOT) pipeline integrity management program (IMP) rule for hazardous liquids pipelines and the proposed rule for gas transmission pipelines require pipeline operators to carry out continual integrity assessments. In-line inspection (ILI) is one of the approved methods. However, some pipeline operators may not be fully aware of the importance of defining the content of the ILI Final Report to enable them to comply with new IMP rules.

Pipeline operators that take a proactive role in defining what is required from ILI final reports will minimize confusion, missed information, or ambiguous results. Requirements regarding (1) ILI tool performance, (2) vendor analysis methods, and (3) Final Report content will help to overcome these potential problems and will be especially helpful if defined prior to any ILI vendor bidding process.

This paper outlines steps for defining the content of an ILI Final Report and provides recommendations to pipeline operators for responding to, validating and accepting ILI Final Reports for integrity management programs.
