PURPOSE: An electrical anti-fouling system of an oceanic facility is provided to sense the operational efficiency of the oceanic facility and control the amount of a current which is supplied to an electrode according to the operational efficiency, thereby creating the proper amount of copper ions. CONSTITUTION: An electrical anti-fouling system of an oceanic facility(100) comprises an anode(200), a sensor unit(300), a control unit(400), and a power supply unit(500). The anode is installed in the oceanic facility. The anode is made of copper contacting sea water. The sensor unit senses the operational efficiency of the oceanic facility changed by marine life attached to the oceanic facility. According to the operational efficiency of the oceanic facility detected by the sensor unit, the control unit estimates the thickness of the marine life which is attached to a side contacted with the seawater. According to the thickness, the control unit outputs a control signal for increasing and decreasing the amount of a current supplied to the anode. According to the control signal delivered from the control unit, the power supply unit supplies a predetermined current to the anode, the oceanic facility, or a cathode attached to the oceanic facility.
