In order to minimize the risk of failures or major
renewals of hull structures during the ship's expected life span,
it is imperative that the precaution must be taken with regard to
an adequate margin of safety against any one or combination of
failure modes including excessive yielding, buckling, brittle
fracture, fatigue and corrosion. The most efficient system for
combating underwater corrosion is 'cathodic protection'. The
basic principle of this method is that the ship's structure is made
cathodic, i.e. the anodic (corrosion) reactions are suppressed by
the application of an opposing current and the ship is there by
protected. This paper deals with state of art in cathodic
protection and its programming in ship structure
