Modification Works of Impressed Current Cathodic Protection System for Steel Sheet Piles Bulkhead Wharf

The steel sheet piles have been protected effectively by the cathodic protection system against seawater corrosion for 40 years. There is no phenomenon of corrosion perforation and corrosion damage. However, many instruments and parts of the cathodic protection system do not work properly now, whilst many new cathodic protection materials are produced and more effective. In order to prevent the steel sheet piles from seawater corrosion, the ICCP system should been modified perfectly.
