Get the Most out of In-Line Inspection Data

Corrosion, erosion and other forms of material degradation can cause critical damage to pipelines, potentially resulting in safety hazards and costly repairs. Having up-to-date and accurate pipeline inspection data, such as in-line inspections (ILI), is important to maintain the integrity of a pipeline.

There are a number of different ways to use ILI data to determine a pipeline’s condition and decide if repair, maintenance or other changes are required. Our integrity management tool Alignment Manager can help you best use ILI data to make these decisions, and track the data changes over time. Here are some tips to help you get the most out of your ILI data.

Establish a Baseline

If building new pipe or acquiring pipe that has been abandoned for a long period, it is best to run an inspection before putting the pipe into operation. This will give an original inspection record to compare future inspections against. The original inspection will show any existing issues, with future inspections showing the progression of the issues not already repaired.

Pick the Right Pig

It is important to pick the right size and type of pig for an ILI run that matches your pipeline diameter. If the pig is too big or too small, you run the risk of the pig getting stuck in the pipe or not gathering accurate information. Also make sure the selected pig has all the necessary technology to detect anomalies based on the type of pipeline being inspected (i.e. gas verses liquid pipelines).

Complete Mappings

When loading ILI data into a database, map all known elements to their corresponding tables. This will make the data more robust and ultimately more accurate.

By following these simple tips, you can help lower the risk of critical damage to your pipeline.
