Lockdown Preventing Vital Excavation? Use a Virtual-dig up to See the Damage You Really Have
With the current restrictions over movement and social interactions, it is more challenging than ever to access critical anomalies for verification and repair purposes. Advanced integrity assessment approaches can be used to maximize the benefit of available in-line inspection data and, in some cases, allow in-field activities to be safely deferred for a period of time, but ultimately it is the accuracy of the inspection data that has the primary influence over the accuracy of the overall assessment.
ROSEN’s Virtual-Dig up (VDU) service incorporates a disruptive technology: Deep Field Analysis (DFA). DFA is an iterative process where an initial estimation of the shape of the metal loss is used to simulate the MFL-A and MFL-C magnetic responses. The simulation results are compared to the actual magnetic responses and the metal loss shape is refined, until the simulated and as-measured results are in close agreement. This process results in a laser scan like 3D profile of the metal loss that can be used to support a range of integrity assessments, including accurate estimation of failure pressure, anomaly interaction and corrosion growth rate estimation. The process requires extensive computer processing effort and support from a range of ILI and data analysis specialists to ensure the reliability of the result. Currently, it is therefore targeted at individual anomalies that are challenging to access for verification and repair purposes.
Join the webinar to learn about a groundbreaking new approach to combining data from multiple magnetic flux based technologies to obtain accurate 3D profiles of metal loss anomalies to support advanced integrity assessments.
