Abstract: This paper reports a field investigation of the metal contact phenomenon in gas pipelines buried underneath urban areas by utilizing the combination of current attenuation survey (CAS) and ground penetrating radar (GPR) methods. CAS examined pipeline integrity based on standard NACE SP0502 and utilized pipeline current mapping (PCM) as the tool. The method enables detecting potential metal contact in a pipeline by investigating the current drop in the measured area. GPR was then utilized by setting the frequency of 450 MHz to determine the exact location of metal contact in the pipeline buried at one to two meters below the ground surface. Utilizing these two methods enables determining the existence of metal contact and its precise location so that it helps the pipeline workers to do excavation and restoration whenever gas pipeline leakage occurs underneath the ground. The results reveal that the CAS indicates the metal contact in the pipeline by knowing more than 50% current reduction. It can be supported using GPR analysis, where anomalies in the contour line indicate the location of metal contact. Therefore, the engineer didn’t have to dig along the pipeline to predict the metal contact location; hence, it saves cost and time.
