Cathodic protection (CP) is routinely applied to the external surfaces of offshore wind turbine monopile foundations to minimize corrosion. When the monopile internals are free-flooding, and therefore also exposed to oxygenated seawater, again, cathodic protection may be applied. In cases of unplanned water exchange through cable entry seals, a small additional surface area, in a gap between the seal and the ‘cable entry hole’ through the steel monopile is then exposed to flowing seawater. Cathodic protection calculations were undertaken to assess whether protection (either applied externally or externally and internally) could penetrate into the small gap and prevent corrosion.
