Abstract

A computational study of the changes in electrical current requirements due to damage to the corrosion preventative coating on the propellers of a U. S. Navy ship is performed. Coating damage is modeled using effective coating efficiency. The boundary element model used has been previously validated by comparison with physical scale modeling experimental results. Trends for higher current demand and lower potential at key locations with increasing levels of damage are presented. The ability to quickly define operating parameters for arbitrary damage levels using boundary element computer models is demon
