This work presents recent advancements in vibroacoustic technology (VT) for pipeline integrity monitoring, with a focus on enhanced flexibility and simplified deployment on existing infrastructure. The new hardware consists of externally mounted sensor blocks based on an interferometric principle, capable of sensing Vibroacoustic waves inside the...

This paper presents a procedure for continuous real-time positioning and tracking of a Pipeline Inspection Gauge(PIG) travelling within a pipeline, by exploiting the pressure transients it generates during the displacement. In fact, the PIG produces recognizable sounds when crossing the welding dents and while sl iding against the pipe walls. This...
