Rosen plans release of corrosion assessment tool at PPIM
Rosen will release its new corrosion growth assessment (CGA) service at PPIM 2017 in Houston, Texas later this month.
CGApro is designed to address industry needs with a holistic integrity solution for corroded pipelines, allowing operators to gain an insight into the location, severity, causes of and solutions for active corrosion threats.
The first stage of CGApro is a thorough investigation of all available pipeline data, conducted by Rosen’s experts in integrity and corrosion management, risk and reliability, and flow assurance.
The results in a complete diagnosis of the corrosion, leading to pipeline segmentations that accurately reflect the variation in internal and external corrosion susceptibility.
This is followed by the estimation of the historical corrosion-growth rate (CGR), achieved using Rosen’s AutoSCAN technology, which uses pattern recognition algorithms to match and normalise metal loss indications between two axial field magnetic flux leakage (MFL A) inspections.
Historical depth changes are then estimated using the change in signal amplitude, leading to a significant step change in the accuracy of historical CGRs.
The final step is a review of engineering practices to ensure effective corrosion management.
By obtaining a complete and accurate distribution of CGRs, optimal CGRs can be selected for integrity management planning, limiting unnecessary repairs while maintaining safety and compliance.
