Designing and constructing large infrastructures like bridges, wind turbines, ships, oil refineries (onshore/offshore), storage tanks, reactors, distillation columns etc. involves investment of large amounts of resources viz. man, money, time, energy etc. The life of such huge infrastructure is a crucial aspect under consideration during its designing and construction phase. As a part of the returns on investment, life of these structures must be as long as possible. On the other hand; these infrastructures always encountered challenges by means of environmental shocks during the entire service life. During the service, these structures come in contact with various corrosive environments like rain water, sea water, sunlight, air pollutants, moisture, etc. When metal of these structures comes in contact with such corrosive mediums, it initiates the metal corrosion.
