HYBRID CATHODIC PROTECTION SYSTEM FOR A CONCRETE OFFSHORE STRUCTURE USING ICCP-TYPE AND SACRIFICIAL ANODE TYPE CATHODIC PROTECTION TECHNOLOGIES AND A METHOD THEREOF CAPABLE OF UNIFORMLY PROTECTING THE CONCRETE OFFSHORE STRUCTURE

摘要

PURPOSE: A hybrid cathodic protection system for a concrete offshore structure and a method thereof are provided to uniformly protect the concrete offshore structure by properly applying ICCP-type and sacrificial anode type cathodic protection technologies to each part of the concrete offshore structure.;CONSTITUTION: A hybrid cathodic protection system for a concrete offshore structure(2) comprises an ICCP type cathodic protection unit and a sacrificial anode type cathodic protection unit. The ICCP type cathodic protection unit comprises an ICCP anode(21) installed in the upper part of a splash zone(C) of the concrete offshore structure. The ICCP type cathodic protection unit applies DC power to the air contacted part of the concrete offshore structure. The sacrificial anode type cathodic protection unit comprises a sacrificial anode(31) positioned in an underwater part. The sacrificial anode type cathodic protection unit protects the underwater part of the concrete offshore structure with the sacrificial anode.;COPYRIGHT KIPO 2013
