Ship anti-corrosion electric system
MGDUFF
currents are initiated at anodic areas of the metal surface, causing
corrosion.
Such corrosion predominates at the stern of a ship, where the combined
effects of increased turbulence and differential metals results in accelerated
corrosion rates.
The application of Cathodic Protection effectively suppresses these
corrosion cells by applying an opposing current from external anodes and if
the propeller is to receive the benefits of cathodic protection then there
must be a continuous electrical circuit between the propeller and the ships
structure.
