Of the reported pipeline failures in the Gulf of Mexico from 1967--1987, approximately 7.5% are a result of internal corrosion. Pipeline corrosion can lead to catastrophic failure causing loss of life, environmental damage, equipment damage and loss of production. Pipeline external corrosion and its prevention and monitoring has long been understood. However, internal corrosion monitoring and its prevention has, in some cases, been over looked. With recent efforts to reduce costs and extend working life in subsea deep water environments, the detection and prevention of pipeline internal corrosion is an important consideration. Conditions at deep water depths (1,000 ft plus) pose challenging, costly obstacles for repair and maintenance. Because of the high cost, any repair to deep water pipelines is generally not acceptable. However, detection and prevention methods exist that can be employed from the surface to minimize the expense. For these reasons, it is important to establish routine programs to control and monitor the rate of internal corrosion in the pipeline over its service lifetime.
