PURPOSE: An ICCP type cathodic protection system for a concrete offshore structure is provided to uniformly protect entire offshore structure by properly supply current for anticorrosion to an underwater part and a water surface part. CONSTITUTION: An ICCP type cathodic protection system for a concrete offshore structure comprises an upper ICCP anode(21), a lower ICCP anode(22), a power supply device(40), and a variable resistance(60). The upper ICCP anode is installed in the upper part of the offshore structure containing a splash zone. The lower ICCP anode is installed in the lower part of the offshore structure containing an underwater part. The power supply device has a rectifier converting alternating current to direct current so that current for anticorrosion can be supplied to the upper ICCP anode and the lower ICCP anode. The variable resistance is connected to the lower ICCP anode.
