In-line Inspection Services for Crack Detection, Sizing and Analysis
RoCD Service Suite
External factors such as corrosion, stresses, pipeline movements and fatigue cycling may lead to the formation of axial and circumferential cracks in pipelines. Safe pipeline operation and avoiding performance and eventual containment loss demand a complete understanding of cracks and crack progression.
Our RoCD Suite of technologies offers comprehensive detection, characterization and analysis of axial and circumferential cracks in your pipeline. RoCD technologies provide superior sensitivity and resolution backed by tailored probe production and industry-leading carrier systems. Our understanding and experience of crack analysis and detection is supported by an in-house crack database that enhances identification and characterization accuracy.

In-line ultra-high-resolution axial crack detection and sizing
Stress corrosion cracking and other forms of axial cracking must be considered and mitigated to ensure safe pipeline operation. Our RoCD EMAT-C Ultra service provides high sensitivity and accuracy for gathering data for improved pipeline integrity management.
The sensors on our EMAT-C Ultra tools are mounted in a way that the corresponding sensor traces overlap, and improved data coverage can be obtained:
- Leading to a 200% sensor coverage in the pipe body and longitudinal weld area
- Improved POD for cracking of up to 95%
- Clockwise and counterclockwise scan of all pipeline anomalies
- Improved sensitivity down to 20x2mm small flaw sizes
Benefits of our RoCD EMAT-C Ultra Service
Utilizing ultra-high-resolution inspection service for better crack detection:
- Improved inspection and data collection, as a higher number of sensors results in higher data resolution
- Detection and identification of all common types of radial, longitudinal cracks that terminate in the internal or external wall surface, including the weld bead
- Applied to lower bound toughness pipelines our Ultra technology leads to a simplification of the integrity assessment due to its better sensitivity
- Probability of Identification for cracking is 90%
- Utilizing EMAT-C Ultra can lead to cost-savings compared to standard EMAT-C due to the reduced need for field verification or excavations
- Technology also suitable for hydrogen pipelines
