General corrosion of the carbon steel jacket is not expected to be significant for a
reasonable intended service life (e.g., on the order of 170 years). However, the carbon
steel jackets are expected to continue to fail in local areas due to pitting corrosion. Life
prediction estimates project that a significant increase in the number of jacket failures
(i.e., through-wall penetrations) may occur after an additional 30 to 60 years of service
life (i.e., between 2035 and 2065). A Fitness-For-Service evaluation was performed for a
recently inspected jacket that showed evidence of pitting within a locally thinned area.
The evaluation concluded that the line is still able to perform its intended function and
can remain in service.
