As wet pipelines become more widely used and understood, their real complexity becomes apparent. Corrosion control in them is achievable if the system is managed competently. A pipeline or a pipeline system is complex and requires the insight of several domain specialists to keep them from corroding. A machine based expert system is not yet available to help in the operational decision making to minimize internal corrosion. The best that one can do today is to utilize a systems analysis on the mentally segmented portions of the system and then to study the impact of the uniting of these segments into an integrated, operating system. The unit operations of the system maybe understood, but new problems are being recognized: a) top of the line corrosion; and b) the complexities of keeping field corrosion inhibitor formulations of constant quality which are also appropriate for the ever changing conditions of the pipeline system which always occur over it's lifetime.

This paper reviews some unit operations, discusses some field experiences on wet sweet and sour pipelines and points to some future problems and opportunities.
