The corrosion protection systems used by U.S. Navy shore facilities for fleet moorings include cathodic protection systems used in conjunction with coal tar coatings on the mooring chains. This article discusses the basic types of mooring designs that are used, and the type of cathodic protection systems used in these designs. Also discussed are further investigations into cathodic protection using a new type and design of anode, and results of field testing are given. Conclusions that were reached include: (1) easier replacement of consumed anodes with the new type of anode, (2) cathodic protection systems can be installed by divers, and (3) by utilizing two 500-lb zinc anodes, a coated 225-ft ground leg can be cathodically protected for fifteen years before anode replacement is necessary. Cost comparisons for moorings with and without cathodic protection systems are also included in the article.
