This final report provides a comprehensive and in-depth review of the current status of in-line inspection technologies including, but not limited to, Magnetic (Axial MFL, Circumferential MFL), and Geometrical (Caliper) methods in terms of their capabilities, limitations and potentials in detection, discrimination and characterization of various forms of pipeline mechanical damage, such as dents, dents with corrosion, and dents with cracks, gouges and dents with gouges. Capabilities of current technologies presented herein are based on validation data supplied by PRCI members. This report reviews...
This final report provides a comprehensive and in-depth review of the current status of in-line inspection technologies including, but not limited to, Magnetic (Axial MFL, Circumferential MFL), and Geometrical (Caliper) methods in terms of their capabilities, limitations and potentials in detection, discrimination and characterization of various forms of pipeline mechanical damage, such as dents, dents with corrosion, and dents with cracks, gouges and dents with gouges. Capabilities of current technologies presented herein are based on validation data supplied by PRCI members. This report reviews and summarizes research regarding the capabilities of current in-line inspection (ILI) based technologies for the detection and discrimination of mechanical damage conducted by Blade Energy Partners in cooperation with participating ILI vendors and PRCI member pipeline operators. This research was conducted in two phases. The first identified the current deployed ILI technologies, vendor claims for capability and performance determination with validation data provided by the ILI vendors. Standardized performance measures were also developed and applied. The Phase I research was presented in an incomplete report, PR-328-063502-R01.
