Seawater forms the largest portion of earth structures. Seawater systems are used by many industries such as shipping, offshore oil and gas production, power plants and coastal industrial plants.The corrosion problems in these systems have been well studied over many years, but despite published information on materials behavior in seawater, failures still occur.

The nature of seawater environment contains elements that accelerate the electrochemical processes of corrosion formation has made it more challenging to protect the assets against corrosion. The rapid development of marine-environment industries increases the demand on the corrosion protection services.
