Corrosion grounding off-shore wind

From Environmental Data Services (U.K.), via Friends of the Irish Environment, comes a report of a Sept. 20 article in the Norwegian engineering journal Teknisk Ukeblad about off-shore wind energy facilities being shut down because of corrosion damage to gearboxes, rotor blades, and other mechanical components. Affected sites include Nysted and Horns Rev off the Danish coast, Barrow in the Irish sea, and Kentish Flats in the Thames estuary. Vestas has suspended sales of its 3-MW off-shore turbine.

The Swedish engineering journal Ny Teknik also carried an article on the subject on Sept. 19, confirming Vestas' problems and noting that the technology still needs a lot of work (how much more money will we throw down this dead end?) to withstand the harsh environment off shore.
