The Cathodic Protection of Metallic Structures in Marine Environments

Theoretical and practical considerations involved in using cathodic protection in sea water are covered, including anode location, polarization, economics and other factors. Specific cases of cathodic protection application are mentioned, including drydocks and ships. Means of checking the effectiveness of cathodic protection are reviewed. The importance of supervision by competent personnel is mentioned, as is automatic control of potentials. Other topics discussed include use of compartmented cells, effect of cathodic protection current on marine growth and problems involved in making cathodic protection automatic. 5.2.1
