Alico Industries Company Limited has extensive experience in design and supply of sacrificial anodes for cathodic protection of offshore wind farm foundations and substations. Major completed projects are Moray Offshore Windfarm East, Scotland, Seagreen Offshore Wind Farm Project located in the North Sea Firth and Formosa II Offshore Wind Farm Project located off the coast of Taiwan.
In general, offshore wind farms utilize cathodic protection systems to safeguard the exterior subsea structures supporting the turbine tower. Mostly, SACP systems are not permitted to be used for ecological reasons and impressed current cathodic protection systems (ICCP) are followed instead. Well in that case, companies have historically provided close mounted anode systems constructed on marine designs which are not ideal for this application. Marine, or ship systems, rely on the fact that the hull of the vessel is covered and that every 5 years the vessel is dry docked and the covering is repaired. This is unlikely possible with an offshore wind farm structure which in any case usually has a large area of uncoated steel.
