|Abstract:||One third of all pipelines worldwide are considered un-piggable by the widely used existing Smart pigs. The vast majority of buried oil pipelines in Europe carry hazardous fluids at high pressure and temperature. While the most common type of InLine Inspection (ILI) pigs use magnetic flux leakage (MFL) techniques. Several limitations of this approach have been identified such as its effectiveness in distinguishing acceptable anomalies from defects, or determining whether the indication is on the external surface or internal as well as the signal reading when the pipe is encased by steel conduits, which is often the case through road and rail crossings. The other common technique used for the purpose is that of Ultrasonic inspection pigs. In this case the process of covering the whole pipeline length with Ultrasonic scan inspection would be both exhaustively time-consuming as well as impractical in sheer data volume to analyse and interpret even at the age of the IOT. iPIM research program is bringing the idea of using Long Range Ultrasonic Guided Waves for a pigging system that is a permanent, reliable, manageable and energy efficient solution to pipeline monitoring. A permanent network of novel low profile Long Range Ultrasonic (LRU) sensors will incorporate on-board signal processing capabilities.|
