Ørsted, Siemens Gamesa and Sif Group currently hold the biggest slices of cakes in their respective fields, when looking at the total installed offshore wind capacity in Europe.
Ørsted is the largest owner of offshore wind power in Europe with 17% of cumulative installations at the end of 2017, followed by E.ON with 8% of installed capacity owned, Innogy and Vattenfall with 7% each, and Northland Power with 4%. The top five owners represent 42% of all installed capacity in Europe, a slight decrease compared to the end of 2016, according to WindEurope.
Siemens Gamesa has the most offshore wind turbines in Europe with 64% of the total installed capacity. MHI Vestas Offshore Wind (18%) is the second biggest turbine supplier, followed by Senvion (8%) and Adwen (6%). In terms of grid-connected turbines in Europe, Siemens Gamesa again holds a share of 64%, and is followed by MHI Vestas Offshore Wind with 22%, Senvion 5% and Adwen 5%. These top four wind turbine manufacturers supplied 96% of the total number of turbines connected. Given that Siemens Gamesa now owns Adwen, the shares of offshore wind turbines attributed to Adwen can be considered as held by Siemens Gamesa.
Sif has the largest overall share of installed foundations, representing 22.4% of all substructures installed in Europe, WindEurope reports. Sif is followed by EEW (21.8%), Bladt (18%), Smulders (11.6%) and Steelwind Nordenham (3.5%).
Monopiles represent 81.7% of all installed substructures in Europe, with the share of jackets (6.9%) rising due to construction at Beatrice. Tripile (1.8%) and tripod (2.9%) foundations did not see any new installations, but the sector witnessed the introduction of two new types of foundation: floating spar buoys (Hywind Scotland) and floating barges (Floatgen).
