Pipeline Integrity

Pipeline Integrity
In trench anomaly inspection

Our specialty is comparing and contrasting the “As-Called” anomalies with the  “As-Found” conditions, and prescribing a repair in accordance with the operators written practice.​

While our specialty is long-seam analysis, we have extensive experience with ID & OD Corrosion, Dents, mechanical damage, SCC, lamination's, mill defects and most other anomalies.  We’ve performed thousands of assessments in all operating environments.​

We constantly review emerging technologies to make sure we are providing the most appropriate techniques, not the latest.​

We offer many other pipeline data services; such as soil pH, pipe to soil potential, soil resistivity, sub-foot & sub-meter GPS, coating inspection, MIC test and hardness testing​

Pipeline rehab NDE is different from Pipeline NDE

Typical NDE informs an operator whether or not a repair is required.​ Effective rehab NDE is equally concerned with correlating the As-found condition to the tool called condition.​ Uncalled Relevant items, or tool misses, are of equal concern.​ Though these conditions may not affect repair requirements, they are critical to an effective ILI program.​ Detailed reporting is important in all NDE, but more critical for Rehab work.​ A rehab report will be part of a continuing process, not just a single job.​

NDE results may be used on future tool correlations.​ The report shows not only what was done, it should represent how an operator is adhering to their program.​ If there’s a problem, a good NDE report will allow a forensic review of the pipe condition.​

If it’s not documented, it didn’t happen.  Reports and mistakes are all that survives back-fill.​ For consistency, we train our technicians in a standardized inspection process​. This Process is divided into distinct “phases”​. Each Phase ends in a series of photos.​ The photos emphasis the sequence of events in the ditch.​ We use distinct colors and symbols to help distinguish the phase of inspection.​

Phases are as follows​

Initial Phase​

Designed to detail “As-called” conditions​

Inspection Phase​

Designed to detail as found conditions, including relevant tool misses​

Repair Phase​

Operators criteria is used to determine an appropriate repair​

All repair related inspections are performed​

Report Phase​

Time sensitive reporting is submitted immediately​, a comprehensive Inspection Report follows, after an in house QA review​
