摘要

Combined Close Interval Potential Surveys (CIPS) and Direct Current Voltage Gradient (DCVG) surveys when combined with GPS time and location stamping ensure improved integrity and accuracy of data collected. Close interval potential surveys are the backbone of pipeline integrity. They assess the effectiveness of the cathodic protection (CP) system which provides protection against corrosion. Direct current voltage gradient surveys indicate defects or damage in the coating on the pipeline but do not indicate the level of cathodic protection. CIPS and DCVG surveys have traditionally been undertaken independently which has made it difficult to correlate coating defects with the level of cathodic protection as indicated by pipe-to-soil potentials. This paper will explore the effectiveness of combined CIPS and DCVG surveys for improved data correlation.
