High demands for the corrosion protection exist during turbine construction offshore. Difficult accessibility makes partial on the spot replacements almost impossible. The coating systems for Steel tower and machine parts, Foundation structures as well as Repair system offshore must therefore be designed in order to withstand the climate over the entire lifetime of the construction, about 20 - 25 years. Further standards relating to corrosion protection in offshore environments, in addition to the EN ISO 12944-6, are ISO 20340 and NORSOK M-501.
