Abstract

Pipeline system is the most efficient transportation of oil and gas in offshore industries. Pipeline as most of other materials is subjected to deterioration over time. The oil and gas industries elevated the concern about pipeline corrosion due to itsnegative results on the efficiency of the pipeline system. The corrosion of pipeline most probably will lead to an environmental issues consequent of materials leakage. The materials inside the pipe tend to react with the pipeline wall leading to serious corrosion and potential leakage. The corrosion takes a place all around the pipe wall. Therefore, the corrosion in pipeline is divided to top of line corrosion (TLC) and bottom of line corrosion (BLC) regarding its location. A study on Top of Line Corrosion Prediction is presented in this research in order avoid system leakage and prevent a future pipe failure. The research result showed a development of corrosion over the years on pipe line. The probability of future corrosion and the range of corrosion in the pipe were studied and prediction equations are modeled. The model show the percentage of corrosion depth in top of line and a comparison between a pipe line historical data was established. The comparison illustrates how the corrosion increases over the years and present its severity. The corrosion orientation model prediction will assist the pipe line inspector to locate the extreme corrosion orientation in the pipe and prevent the further decay.
