Threats and Integrity Management -- Anomaly Detection and Characterization

The project assesses ultrasonic and electromagnetic inspection techniques for composite overwrap repairs for pipelines. Examples of the new techniques evaluated in this project include Dynamic Response Spectroscopy (DRS) “Multi-skip” UT, Sonomatic Electromagnetic LFET/ OSET, and TesTex Inductosense (WAND) – embedded sensors.

The evaluated technologies provide an advancement in the inspection of composite repair materials, bond quality between the composite material and the pipe, and the inspection of the pipe underneath the repair

Increased Safety - Inspection of disbondment between the composite repair and the pipe is one of the critical components of pipeline repair. Monitoring after the application of the repair provides an effective means to detect and correct these issues.
