This paper describes the development of a computer model to evaluate the performance of replacement galvanic anodes for a 25-year old offshore North Sea platform. The platform had a hybrid cathodic protection system comprising impressed current anodes mounted around the structure as well as aluminum – zinc – indium galvanic anodes. Over a period of time a number of the impressed current anodes had failed which together with natural consumption of the galvanic anodes had started to result in under polarization for sections of the structure. Consequently a cathodic protection upgrade was started, incorporating retrofitting of new galvanic anodes to the structure.
