To study the influence of marine fouling upon corrosion of ASTM A36 carbon steel structures, test racks were immersed in the Kaohsiung Harbor, Taiwan. Weight loss measurement and electrochemical impedance spectroscopy (EIS) were applied to evaluate corrosion of the steel. Five-year results indicate that the attachment of marine organisms on the steel surface retards general corrosion, but localised corrosion could occur underneath the marine organisms. The corrosivity of seawater is site specific and the average corrosion rate of ASTM A36 ranged from 0.2 to 0.3 mmm/year. In short term immersion tests corrosion products tend to form a porous rust layer on steel surface, while a dense and thick rust layer developed with increasing exposure time. Equivalent circuit model is established to simulate the attachment of marine organisms upon corrosion of carbon steel.
