It’s not that long ago – 2011/12 – that vessel owners were building assets for an industry building out 6MW tur- bines. This year, 9.5MW turbines with 164-meter-diameter rotors will be in- stalled at the Northwester 2 offshore wind farm in Belgium. Siemens Gamesa will also be prototyping its 10MW SG 10.0-193 DD prototype turbine, with a 193-meter-diameter rotor, at the Danish
