Abstract
The long term creature corrosion behaviour of carbon steel fouled by marine creatures has been investigated at three corrosion test stations located off China coast at Qingdao, Xiamen and Yulin station, in the Yellow Sea, East China Sea and South China Sea, respectively. Fouling by sea creatures can accelerate localised corrosion, but reduce the rate of general corrosion to great extent. The new concept of an environmental corrosion coefficient has been developed based on the analysis of fouling corrosion behaviour, and the revised equation of corrosion depth versus exposure time for carbon steel in sea water is in agreement with the field results. The new equation allows prediction of the final corrosion rate after prolonged exposure.
