Threats and Integrity Management -- Anomaly Detection and Characterization

Funded by the California Energy Commission, the girth-weld scanning technology uses an EMAT girth weld scanner (GWS) module mounted on an ILI inspection platform. Diakont used their pipeline testing experience to streamline future iterations of the tool, including smaller diameter pipes and increased ability to navigate bends, and to optimize marketing efforts.

Current Commercially available in-line inspection include hydro-testing, external ultrasonic testing, and magnetic flux leakage (MFL) technology . This technology uses an EMAT weld scanner module mounted on existing remotely operated diagnostic inspection system (RODIS).

Increased Safety - The technology can potentially early weld defections and increase the reliability of girth-weld inspection for pipeline operators, thus increasing pipes safety and allowing the potential for increased inspection scope and frequency.
