An In-Line Inspection (ILI) is really just a snapshot of the current condition of your pipeline on a specific date. Depending on the technology used and when the pipeline is inspected, different “views” of the pipe’s condition are created. Which means no single ILI will give you the true condition of your pipeline.
This is where run comparisons come into play. Run comparisons help QC new data building confidence in the results, increases the value of each run, and provides data for deeper and more accurate analytics using the comparison results.
There are a handful of options when it comes to doing an ILI run comparison; completing it in-house, outsourcing to an ILI vendor, outsourcing to a service provider, or maybe your organization just doesn’t do it. Trying to decide what is best for your organization? We’ve got your benefits and drawbacks of each.
