How large offshore wind turbines are challenging bearing designs

Since 2012, offshore turbines with total power outputs in excess of one GigaWatt (GW) have been coming on stream in European waters every year. According to WindEUROPE, Offshore wind in Europe saw a net 1,558 MW of additional grid-connected capacity installed in 2016.
Despite the challenges of constructing offshore turbines, the capacity there is expected to grow as suitable land-based sites become scarcer and operators take advantage of the greater consistency of wind at sea. The output power of offshore turbines also tends to be greater than their land-based counterparts. According to WindEUROPE the average power output of offshore turbines installed in 2016 was 4.8 MW. Turbines of 9 MW or more capacity are now in the launching stage – Vestas’ V164-9.5 MW development is a prime example
