Real-Time Gauge Positioning And Inspection During Pigging Operations In Gas Pipelines
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...
