Traditionally, close interval potential surveys (CIPS) and direct current voltage gradient surveys (DCVG) have been undertaken separately and the corrosion engineer has been saddled with the task of trying to correlate the results of these surveys, to assess the level of cathodic protection on the pipeline and the effect of coating holidays on the effectiveness of the cathodic protection system. This paper outlines a method of undertaking both surveys simultaneously and the benefit to the corrosion engineer of having accurate and correlated surveys. The paper also deals with surveying pipelines affected by stray currents.
