ABSTRACT:
A cathodic protection system for metallic structures disposed in contact with marine brine includes a plurality of sacrificial marine anodes mechanically linked in a chain suspended above the brine with a portion of the chain immersed in the brine. The chain of anodes is electrically coupled to the structure, and means are provided for selectively releasing and retrieving the chain from storage to correspondingly increase or decrease the length of chain immersed in the brine.
