Qualification trials were conducted in a simulated subsea environment at Tracerco’s headquarters in northeast England.
These determined the depth limit for reliable probability of detection and typical sizing tolerances for metal loss anomalies at the subsea pipes’ inner and outer positions.
Tracerco added that the capabilities were shown to be in compliance with recognized guidelines for offshore pipelines and were further validated using non-destructive examination standards for the CT technique.
Ben Metcalfe, Subsea Technical Manager at Tracerco, said: “The results give our customers an assurance that the qualification was conducted in compliance with international standards and guidelines foroffshore pipelines.”
Discovery has to date completed more than 1,000 scans for subsea pipeline inspections, obtaining accurate measurements, Tracerco claimed, of pipe wall thickness through any type of protective coating, while simultaneously diagnosing and characterizing flow abnormalities without interruption to normal pipeline operations.
The company added that last year the system helped save operators in the Gulf of Mexico and offshore the Arabian Peninsula to save millions of dollars.
