Cathodic Protection System for Fleet Moorings.
Abstract
A cathodic protection system was developed for protecting from corrosion both the underwater portion of a mooring buoy and its ground tackle. The final design of this system protected both buoy and chain for 3-1/ 2 years, and sufficient zinc appeared to remain for at least another 6-1/2 years of protection. The system performed well on both a sandy and a muddy bottom. The zinc anodes used on the ground tackle were specially cast on steel chain links to become an integral part of the chain system. The tight riser-chain secured to the peg-top buoy had the required electrical continuity to permit the necessary flow of current for protection, but it was necessary to use a steel cable woven through the links of each ground leg to achieve electrical continuity there. A cost analysis indicates that use of such a cathodic protection system can result in a considerable reduction in costs associated with maintenance of Fleet moorings. (Author-PL)
