Description
Summary:	This paper presents the conceptual design and prototype validation stages of the development of an in-line inspection tool that is based on circumferential guided waves generated by shear horizontal electromagnetic-acoustic transducers (EMATs). By combining the data from these sensors with information from accelerometers and an odometer, the tool can evaluate the integrity of the pipeline non-destructively and record the longitudinal and circumferential position of wall thinning areas and geometrical features or anomalies. This paper focuses on the identification of pipeline features, which is a key aspect in avoiding false-positive calls during real inspections. The performance of the tool in detecting and identifying such features in near-operational conditions in a defect-free qualification pipe loop is evaluated.
