ROSEN to launch corrosion growth assessment service at PPIM

The complex nature of corrosion has compelled inspection and integrity specialists to continually advance technology, improve knowledge, and build experience in corrosion management. ROSEN’s new offering – CGApro – addresses the industry need with a holistic integrity solution for corroded pipelines.

The first stage of CGApro is a thorough investigation of all available pipeline data, conducted by experts in integrity and corrosion management, risk and reliability, and flow assurance. The result is a complete corrosion diagnosis, leading to pipeline segmentations that accurately reflect the variation in internal and external corrosion susceptibility.

This is followed by the estimation of historical corrosion growth rates (CGRs), achieved using ROSEN’s new technology, AutoSCAN (automated signal correlation and normalisation). Using pattern recognition algorithms, AutoSCAN precisely matches and normalises metal loss indications between two ROSEN 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. 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.

The final step is a review of engineering practices to ensure effective corrosion management. ROSEN works together with operators to define and implement a corrosion management strategy, consisting of mitigation and risk based inspection and monitoring plans.

With CGApro, operators therefore gain unparalleled insights into the location, severity, causes of and solutions for active corrosion threats.
