Enbridge and G.E. company Baker Hughes launched testing of new, ultrasonic phased array pipeline inspection tool sensors designed to enhance accuracy and identification of crack features and to deliver greater detail on the condition of a pipeline. The testing phase follows 14 months of development of a multi-year research and development project to advance pipeline inspection tool sensor technology and, ultimately, pipeline safety. Similar to MRI or ultrasound technology used in the medical industry, pipeline inspection tool sensors provide the ability to detect and accurately characterize anomalies that could affect the health of a pipeline. The next generation of inspection tools will provide more accuracy and higher resolution, enabling better maintenance and an overall improvement on the assurance of pipeline safety. The next generation of phased array sensor technology will represent a significant step change in pipeline inline inspection, enabling a more comprehensive assessment of the threats to pipeline integrity, the companies said. The sensors are mounted on a robotic inspection device, or smart pig, which travels along the inside of a pipeline, measuring the condition of the pipe wall as it goes.
