Dig Verification Program

Pipeline inspections often turn up hundreds of defects but knowing which anomalies require remediation — and how soon it’s needed — isn’t always clear cut.

As part of your comprehensive and systematic integrity management program, TDW performs multistep dig verification to confirm that in-line inspection (ILI) data matches actual defects. That helps you eliminate guesswork and make knowledge-based decisions to protect your assets.

The TDW dig verification program includes:

  • Performing an inspection based on your line condition, schedule and budget
  • Reporting preliminary results
  • Doing in-ditch verification — a vital step in ensuring tool accuracy
  • Analyzing results
  • Reporting specific findings so you can prioritize repair or replacement

This continual feedback loop helps improve tool accuracy over time, allowing TDW to make slight changes in technology, improve future integrity runs and validate processes.
