Internal corrosion assessment and prevention in transmission pipelines is a significant problem. Both wet gas and dry gas transmission pipelines are frequently operated under conditions that may lead to substantial internal corrosion of the pipeline, causing consequent damage to both operations and personnel/population.

This paper describes recent developments in Advanced Internal Corrosion Direct Assessment (ICDA) modeling and a solution methodology to quantify corrosion damage to facilitate development of proactive inspection and maintenance programs. The objective of this proposed methodology is to build a foundation to develop an enhanced framework of systems using current technologies to identify pipeline components with real potential for damage and failure, as well as promote improved integrity characterization through the application of real-time corrosion monitoring technology.
