A Statistical Approach to the Modified Impress Current Cathodic Protection (ICCP) for Pipeline Systems.

Abstract


An attempt to predict theoretically, the corrosion protection of oil pipelines by Impressed Current Cathodic Protection (ICCP) was embarked upon using data from an ICCP system in practice for three years (2004 through 2006). The concepts and principles used in Cathodic protection is briefly explained with a discussion of the forecasting models employed. The forecasting methods employed include the Simple Moving Average Method, the Simple Exponential Smoothing Method and the Double Exponential Smoothing Method. The forecasting models were applied on the collected data and results obtained and tabulated. The forecasted results were plotted and superimposed on the actual (collected data) and observations made. The results show that the forecasted results followed closely to the actual data, confirming that forecasting results can only be relied upon in ICCP monitoring if there are no coating damages, interference problems and other anomalies.

Keywords: Impressed Current Cathodic Protection (ICCP), Simple Moving Average Method, Simple Exponential Smoothing Method and the Double Exponential Smoothing Method.
