An analysis was made of the cathodic protection systems of fifteen (15) fixed offshore platforms. These steel template structures are located in the warm waters off the coast of the United Arab Emirates with water depth varying between 125 and 185 feet. The operator employs a systematic survey program to monitor the corrosion protection systems including the assessment of sacrificial anode depletion, and measurement of the anode and platform potentials. These data are used to design new anode retrofits for the older structures to extend the life of the CP systems. This paper presents an analysis of the field survey measurements, the method used to evaluate when new anodes are required, how many are needed, and where to locate retrofit anodes.
