Abstract:
Corrosion represents one of the largest through
life cost component of ships. Ship owners and operators
recognize that combating corrosion significantly impacts the
vessels’ reliability, availability and through life costs. Primary
objective of this paper is to review various inspections,
monitoring systems and life cycle management with respect to
corrosion control of ships and to develop the concept of
“Corrosion Health” (CH) which would quantify the extent of
corrosion at any point of ships’ operational life. A system
approach in which the ship structure is considered as a
corrosion system and divided into several corrosion zones, with
distinct characteristics, is presented. Various corrosion
assessment criteria for assessment of corrosion condition are
listed. A CH rating system for representation of complex
corrosion condition with a numeric number along with
recommendations for repair/maintenance action is also
discussed

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
