MHI Vestas Offshore Wind (Aarhus, Denmark) announced June 27 that the 9.5 MW model of its flagship V164 turbine platform has received its Rotor-Nacelle-Assembly Component Certificate.

The final certification comes one year after MHI Vestas announced the 9.5 MW turbine to the market, moving the industry one step closer to double-digit MW turbines in the water. The announcement speaks to the industry’s need for cost-effective power upgrades. Since the V164 was launched, MHI Vestas has uprated nominal power from 8.0 MW to 9.0 MW, and now to 9.5 MW – all with minimal design modifications.

Senior product manager, Anders Bach Andersen, says, “From the very beginning, we designed the V164 with reliability and cost-efficiency in mind. We’ve managed to increase power output 20% without materially affecting cost. For today’s offshore wind customers, it’s more critical than ever that nominal power can substantively increase without a major re-design of the turbine platform.”
