In monitoring an impressed current cathodic hull protection system, it is important to ensure that the propeller screw receives the same cathodic protection as the hull. What should be checked?
A
Ensure adequate individual anode current to the anode closest to the propulsion shafting as it passes through the hull.
B
Ensure adequate grounding carbon brush pressure on the rotating shaft by checking associated current.
C
No checks are necessary since the propeller screw is bronze and needs no protection.
D
Nothing can be done short of checking the propeller screw at drydock availabilities.
