For more complete vessel protection when using an impressed current cathodic system, what other features are built into the system?

Correct Answer: Option D — straps connect the rudder with the hull and the propeller shaft is grounded through a slip ring/brush arrangement

Rotating steel propeller shafts act as generators of stray electrical currents through seawater friction. To ensure complete ICCP system effectiveness, heavy-duty grounding straps link the hull to the rudder, while silver-graphite slip rings and carbon brushes safely ground the rotating shaft, preventing localized pitting and bearing journal damage.
