This paper presents guidelines to enable a pipeline operator to assess whether the results of a metal loss in-line inspection (ILI) should be deemed acceptable. Acceptance depends on passing two checks, Verification and Validation. Verification is the process which ensures that all planning, preparation, execution, and analysis of the inspection were conducted according to ILI vendor processes to meet specification and prescribed industry standards. It assumes that a successful run is a consequence of good planning, preparation, execution and analysis. Validation is the process by which the results of an ILI run are compared to independent measurements. The Validation process depends on the results of the ILI and available information. Passing both the Verification and Validation checks is required to accept of the ILI run.
