Characterizing the performance of In Line Inspection (ILI) continues to be a subject of ongoing debate. Knowing the accuracy and reliability of ILI measurements is important for determining optimum integrity rehabilitation project scope, re-inspection interval and the risk associated with the pipeline section examined. The introduction of API 1163 (In-Line Inspection Systems Qualification Standard) is a positive step in defining the key metrics for qualification of ILI results. Qualifying these metrics requires verification measurements having accuracies an order of magnitude higher than in-line-inspection. LasersureSM provides a process which uses high resolution, high accuracy, in-the-ditch, Laser Profilometry measurements which satisfies these requirements and therefore is well suited for this purpose. This presentation will identify the components of the LasersureSM process and through example the potential impact of this process for management of pipeline integrity.
