Abstract:

Cathodic Protection is the most typical method of preventing corrosion from steel surfaces of offshore structures. In addition to Cathodic Protection, the coating might be applied to provide more efficient protection. Especially for the system that Sacrificial Anode Cathodic Protection (SACP) is applied since SACP produces its anode without any generator. Hence coating has a strong combination with Cathodic Protection. On the other hand, coating types change based on thickness and layer. According to DNV (Det Nortske Veritas) guide, there are four coating types categorized in terms of Coating Breakdown Factor (f_c) and each type has different constant values of coating properties, which will be used for anode calculations. Using these parameters, anode requirements can be calculated using the DNV guide and differences among coating types can be observed. This paper aims to determine the differences between coated and uncoated structures in terms of anode type, anode size, environmental conditions and other factors by means of the DNVGL-RP-B401 guide. In order to observe these differences, a hypothetical wind turbine to be designed as SACP and located on the Canary Islands is considered in this study.
