Corrosion protection concept offers 30% cost saving

Experience to date on E.ON’s Arkona offshore windfarm project, the first use of a new corrosion protection concept, suggests that it is significantly less expensive than conventional techniques

As first highlighted in the 3rd Quarter 2017 issue of OWJ, the concept of using thermally sprayed aluminium to prevent corrosion is widely used in the offshore oil and gas industry but has only recently begun to be used in the offshore wind industry.

Corrosion protection and management of foundations for offshore wind turbines is a potentially costly undertaking in terms of initial capital outlay and in long-term maintenance. The current solution of paint and sacrificial anodes not only slows foundation construction time but has a limited lifetime that requires frequent inspection and maintenance activities. Anodes require additional secondary steelwork to be added to a foundation, and paint requires many days to dry, slowing production times and adding cost. The first application of thermally sprayed aluminium was on the Arkona offshore windfarm, for which the foundations have now been installed.
