CATHODIC PROTECTION SYSTEM FOR A CONCRETE STRUCTURE USING AN UNDERWATER SACRIFICIAL ANODE AND A SACRIFICIAL ANODE ATTACHED TO A PROTECTIVE JACKET

摘要

Disclosed is a cathodic protection system for a maritime concrete structure which is divided into an underwater unit and a marine unit. The system comprises: a bulk type primary sacrificial anode located within the underwater unit; a terminal box installed in the position of the marine unit free of the seawater and electrically connected to the primary sacrificial anode; and an FRP protective cover arranged at least in a portion of the marine unit to cover the periphery of the maritime concrete structure.
