In-line Inspection Services for Crack Detection, Sizing and Analysis

RoCD Service Suite 

External factors such as stresses, earth movements and fatigue may lead to the formation of axial and circumferential cracks in pipelines. Safe pipeline operation and avoiding performance and eventual containment loss demands 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 high-resolution circumferential crack analysis

Our RoCD UT-A Service offers the greatest sensitivity and spatial resolution when detecting and sizing circumferential cracks. These pipeline anomalies, along with fatigue cracking, are exacerbated by demanding loading conditions and exterior movements such as landslides, earthquakes, expansion loop torsion, offshore free span and sagging. 

  • Crack depth sizing across full wall thickness
  • Ultrasonic wave technology applied in crack detection
  • Reliable service backed by technology and experience
  • High availability and wide range of tool configurations

Benefits of our RoCD UT-A Service

  • Special probe design and high-resolution features deliver enhanced anomaly characterization
  • Robust, flexible sensor carriage gives exceptional precision and resolution
  • Versatility of tool configurations addresses varying operating requirements of individual pipelines
  • Successful Post-ILI crack assessment and final report in 90 days or less, facilitated by a team of technical and data evaluation experts
  • Reducing the need for dig ups by providing reliable data through this crack inspection service for extended sizing
