By Emma C. Edwards, Career Development Fellow in Engineering, University of Oxford

You may have seen a wind turbine in the sea before, but chances are you were looking at a “fixed” turbine – that is, one that sits on top of a foundation drilled into the seabed. For the new frontier of offshore wind power, the focus is on floating wind turbines. In this case, the turbines are supported by floating structures that bob and sway in response to waves and wind and are moored with chains and anchored to the seafloor.
