Forensic Corrosion Engineering (FCE) seeks to understand the contributing causes and underlying mechanisms of corrosion damage or ultimately failure and leverage this knowledge through the framework of a Corrosion Management System to mitigate risk resulting from the corrosion threat. In-depth understanding of the active corrosion threat mechanisms in a pipeline system improves the operator’s ability to identify effective mitigation and monitoring measures and increases confidence in risk management programs. Based on FCE results application of “lessons learned” is discussed as part of a Corrosion Management System. Essential elements of the FCE approach which include integrating the disciplines of chemistry corrosion/materials science microbiology and oil and gas operations are also discussed.
