Management of Hydrogen Sulphide (H2S) Gas in Wind Turbine Sub-Structures

Published 6 May 2016

In November 2013, elevated levels of the gas hydrogen sulphide (H2S) were detected within the foundations of some of the wind turbines at the Teesside offshore wind farm. This O&M Case Study by Dr Conaill Soraghan presents the approach adopted by EDF-ER as wind farm owner to identify the source of the gas and manage the hazard on an ongoing basis.
