Mitigation of corrosion of pipelines in a crude oil reserve storage facility in Central Europe is described. This top-down study covers a number of factors affecting corrosion in crude oil such as water content, aggressivity of the water phase, kinetics of water-oil separation, effect of dissolved oxygen, effect of stored crudes quality, frequency of oil movement inside the pipes, steel grade, possible contribution of MIC, presence of deposits, and many others. One of the key roots of corrosion acceleration is the water phase separation. Several approaches were suggested to limit corrosion, considering both difficulties of design changes and economic costs.
