Issues considered during the design of an impressed current type cathodic protection (ICCP) system for corrosion control on the submerged external surfaces of the steel ice shields on the bridge piers are presented. The challenges and cathodic protection (CP) system design solutions, associated with providing protection to the underwater CP components against ice damage, are discussed. The ICCP system is described including the different CP equipment arrangements utilized, based on the various pier configurations and construction methods. Results of the system effectiveness are also discussed.
