ABSTRACT (Confirm« on reveree aid« If neceeeary tnd Idontlty by block number.) This 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.

A protection potential of -II50 millivolts was found to protect galvanic couples of surface-effect ship materials adequately at 90-knot velocities. Finally, updated design guidelines for impressed-current cathodic protection systems on surface-effect ships are presented.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
