Determining whether life extension of an SCR system is pos- sible requires understanding and evaluation of the potential failure mechanisms. These could be overstress, fatigue, internal or external corrosion, erosion, elastomer failure in the ? exjoint,

Evaluation of each failure mechanism requires past opera- of steel catenary risers tional data, direct assessment measurements, future expected operational data and system modeling. While the process is a
