State-of-the-art pipeline inspection tools with single element ultrasonic probes are limited with regard to their inspection capabilities because of the fixed arrangement of the sensors within a sensor carrier. Phased Array Technology allows simultaneously performing different measurement tasks, e.g. crack detection and metal loss inspection; hitherto two measurement runs with different sensor carriers were required. With Phased Array sensor system, as applied in the new UltraScan DUO(TM) ILI tool, the ultrasound beam generated by virtual sensors can be directed to different incident angles, its characteristics can be adjusted to match the actual pipeline medium and measurement task. The sizes of the virtual sensors and the sensor overlaps can be optimized, e.g. for the measurement of small size pits. The usage of Phased Array Technology allows higher inspection speed and improved defect detection capabilities. The measurement principle and the inspection tool will be described. Prototype measurement results will be presented.
