We are interested in learning of methods used by agencies to assess ocean outfalls.  Of particular interest is internal inspection, structural assessment and the estimation of remaining service life.  Our outfall of concern ranges from 48-inch to 72-inch in diameter, extends 8,700 feet into the Pacific Ocean, to a depth of 160 feet. Outfall age is roughly 50 years. External assessments are completed regularly with divers (in shallow depths) and ROVs (deeper). There is a group of agencies in California that would like to learn from the experiences in other parts of the country and beyond.
