A corrosion protection coating system from Sherwin-Williams has been applied to monopile foundations for the He Dreiht Offshore Wind Farm in the North Sea. The monopiles were manufactured by Steelwind Nordenham. Each foundation measures up to 71 metres in length and weighs around 1,350 tonnes. To protect the steel structures from long-term exposure to saltwater, currents and splash zone conditions, the Dura-Plate SW-501 Series epoxy coating was selected.
The coating is a 100% solvent-free, high-build epoxy system designed to provide a dense barrier against corrosion. It is intended for offshore structures requiring extended service life with limited maintenance access. The system is compliant with relevant offshore corrosion protection standards, including VGBE-S-021-02-2023, NORSOK M-501 and ISO 12944-9:2018.
Application took place at Steelwind Nordenham’s fabrication facility in northern Germany. The coating was applied by Robert Krebs using manual airless spraying to achieve consistent film thickness and surface coverage across the large-diameter monopiles.
The He Dreiht project, developed by EnBW, comprises 64 turbines with a total capacity of 960 MW. The wind farm is located around 90 kilometres north-west of Borkum and is scheduled to supply renewable electricity from spring 2026.
