IMPRESSED CURRENT CATHODIC PROTECTION SYSTEM

摘要

An impressed current cathodic protection system for a marine structure includes an elongated supporting member which can be lowered into position adjacent the underwater structure to be protected, an underwater power supply mounted in the supporting member for converting high voltage alternating current from a source above the water's surface to low voltage direct current, one or more anodes mounted on the supporting member near the power supply, a potential controller for regulating the level of protection provided, and a reference cell for monitoring the system.
