ICCP - Power Supply Rating
ICCP power-supply rating from required hull-protection current, voltage, and design margin - the unit spec for new-build / retrofit.
Design current
313A
DC power
7.50kW
AC power supply
8.82kW
Formula, assumptions, and limits
ICCP supply typically 30–100 kW total. Voltage set on-line from reference electrodes - feedback loop holds hull at −850 mV Ag/AgCl. Power rating sized for worst-case biofouling.
