Following customer feedback, the company developed a new technique for detecting the presence of localized metal loss defects on subsea pipelines, which it claims is up to five times faster than previous capabilities.
Once the scanning method detects a potential anomaly, a more detailed/accurate overview can be provided by extending the duration of the fast scan. This eliminates the requirement for a separate scan and the need to deploy a secondary device to validate the findings from the initial fast scan inspection.
Tracerco’s Kim Thye Lee said: “Operators now have the ability to quickly and accurately screen subsea pipelines to determine whether the integrity is within the acceptable tolerance specification.
“With non-intrusive inspection through any type of protective pipeline coating, defects can be fully characterized faster than ever, without interrupting production. This will enable operators to save on time, resource, and ultimately the cost of an inspection campaign.”
The first two campaigns to deploy Discovery for fast scan purposes were recently completed on a large diameter export pipeline in the Middle East and over a range of infield flowlines and jumpers in the Gulf of Mexico.
According to Tracerco, the quality and volume of inspection data obtained gave the clients statistical confidence that the results were representative of the condition of their entire system.
