Many offshore structures (largely platforms and pipelines) will require a cathodic protection retrofit at some point during their lifetime. This is due to the age limitations of the original cathodic protection anodes and operators' new desire to extend the life of existing offshore infrastructure. This paper explores the conventional methods of anode replacement and then compares them to the newer methods developed by Deepwater Corrosion Services and others. These new proprietary products and methodologies are designed to cut installation time, while still providing an excellent life extension for the asset of up to 25 years.
