Impressed-Current Cathodic Protection for Surface-Effect Ships

Abstract

A laboratory investigation was conducted to provide background information for impressed-current cathodic protection of surface-effect ships. The optimum protection potential was identified by performing polarization experiments in flowing seawater (0-77 knots). Current requirements, at this potential level, were generated for SES 100B by combining the laboratory results with calculated surface areas of the wetted hull and appendage components. Impressed-current cathodic protection for surface effect ships is discussed from the viewpoint of the craft designers. After a brief explanation of the fundamental principles of cathodic protection, the function of an impressed- current system on surface-effect craft is discussed in general, and a design procedure is outlined and specifically applied to SES 100B. A brief discussion of commercially available cathodic-protection-system components is presented.
