ILI tool validation: feature assessment and mapping
by Al Crouch, Patrick Porter, and Todd Goyen

In-line-inspection reports are now forming the foundation of integrity-management plans. Reliance on these reports demands that tool data be verified and validated. This validation requirement, while technically prudent, will also be a recommended practice in new procedures being developed.

Tool validation is a difficult task requiring detailed field measurements of features in a format that can be compared directly to the ILI data. This paper presents an overview of the validation process and describes the development and testing of a new device for measuring, documenting and assessing external corrosion on steel pipelines.

Feasibility and design of the new system were funded by the US Department of Energy through the National Energy Technology Laboratory.
