Abstract: The repair strategy for reinforced concrete structures in marine environment suffering from chloride-initiated corrosion usually includes cathodic protection. Three major coastal bridges are located in the sea south of Funen. During the period 2008 to 2015, several cathodic protection systems (CP-systems) have been designed and installed on the structures of these bridges. The CP-systems used are impressed current cathodic protection (ICCP) for girders and bridge piers above water and galvanic anode cathodic protection (GACP) for the submerged parts of bridge piers. The ICCP anode systems include titanium anodes with mixed metal oxide coating shaped as mesh, rods and ribbons all embedded in concrete or mortar, and the GACP anodes are aluminium alloy. The systems are automatically operated and access for monitoring and adjustment is carried out remotely via the internet. This paper presents considerations regarding the cathodic protection designs, the challenges during installation and evaluation of the performance of the cathodic protection systems seen from the Consultant’s point of view.
