Design guidelines for impressed-current cathodic protection systems on surface-effect ships

The report presents results of various tests performed to establish design guidelines for the use of impressed-current cathodic protection systems on surface-effect ships. These results show that commercially available reference cells can be used in this application, and that dielectric shield materials, which can withstand the applied voltages, are available. Size limits were set for dielectric shields on the SES-1 OOB. A protection potential of -1150 millivolts was found to protect galvanic couples of surface-effect ship materials adequately at 90knot velocities. Finally, updated design guidelines for impressed-current cathodic protection systems on surface-effect ships are presented.
