In this work, a case study for the Life Cycle Costing (LCC) analysis to quantify and compare different corrosion mitigation methods based on their effectiveness and make an informed decision on the strategies to minimize the costs due to corrosion is presented. The LCC for corrosion constitutes the costs of corrosion monitoring and control, the equipment replacement costs, and the loss of production due to down time. In this work, the corrosion rates encountered in a gas gathering facility is assessed based on data provided in corrosion monitoring and inspection reports. The effects of employed corrosion control strategies on observed corrosion rate values are analyzed to develop a quantitative estimation of their effectiveness. A model is developed to calculate a resulting corrosion rate based on a selected combination of corrosion control methods. An economic analysis is then performed to include all elements for corrosion costs. The process is repeated for scenarios with better corrosion control and the optimal LCC strategy is proposed by comparison of various scenarios.
