Title : Flowline integrity assessment using Magnetic Flux Leakage (MFL) inspection
Abstract:
Performed Magnetic Flux Leakage (MFL) pipeline inspections on oil and gas flowlines as part of asset integrity and corrosion management programs. The scope included planning and overseeing MFL scanning activities, reviewing inspection data, and evaluating pipeline conditions to identify potential integrity threats. The MFL technology was utilized to detect and size metal loss anomalies, including internal corrosion, external corrosion, pitting, wall thinning, and other defects that could affect pipeline reliability and safe operation.
Following the inspection campaign, detailed analysis of the MFL results was conducted to assess anomaly severity, estimate remaining wall thickness, and prioritize repair requirements based on risk and fitness-for-service considerations. Inspection findings were documented in comprehensive technical reports, highlighting defect locations, dimensions, corrosion growth concerns, and recommended mitigation actions. Repair strategies included composite wrapping, pipe section replacement, clamp installation, localized repairs, and enhanced monitoring programs where applicable.
The inspection program contributed to improving pipeline integrity, minimizing the risk of leaks and failures, and ensuring compliance with industry standards and company asset management requirements. Close coordination was maintained with operations, maintenance, corrosion, and engineering teams to develop effective repair plans and optimize inspection intervals. The successful execution of MFL inspections provided valuable integrity data, supporting informed decision-making, risk reduction, and the long-term reliability of critical flowline assets. The inspection program enabled targeted repairs and maintenance activities, significantly reducing unnecessary excavation and replacement work. By accurately identifying critical anomalies and prioritizing repair locations, the project minimized production interruptions, reduced operational costs, optimized manpower utilization, shortened inspection and maintenance schedules, and enhanced overall asset reliability and safety while maintaining continuous flowline operation.
