Threats and Integrity Management -- Anomaly Detection and Characterization

The SCT™ utilizes the measurable relationship between stress and magnetization: changes in localized stress on the pipeline wall cause predictable changes in the pipeline’s natural magnetic field. The analysis of this remotely collected magnetic data is then used to determine the presence of defects, their location and their magnitude of stress.

The device complements ILI inspection and delivers an accurate map of the pipeline route including its depth of cover. The technology is useful in areas of soil erosion as it will help reduce the possibility of damage through mechanical impact from farming and excavation equipment. It is also useful to an operator who has acquired pipelines with incomplete records. The technology can also be used to report the location of a specific girth weld and thereby enhance the accuracy of excavations.

Increased Safety - By targeting specific sections to monitor known defects on a longer pipeline, SCT™ eliminates the need to initiate a full-length “pig” run. This means less downtime and more savings.
