MingYang unveils 11MW turbine

MingYang has launched a new 11MW hybrid-drive offshore wind turbine, which is due to be the largest model offered by a Chinese manufacturer.

Ming Yang's MySE 11-203 machine is a step-up from its existing portfolio, including its 7.25MW turbine (above)

It aims to produce a prototype of its new MySE 11-203 machine in 2021 and make it commercially available in 2022.

The new turbine incorporates a compact integrated medium-speed drivetrain with a permanent-magnet generator, which MingYang claims is the “world’s largest hybrid drivetrain”.

Its 99-metre-long blades will be made of carbon and fibreglass and give the turbine a 203-metre diameter rotor.

The turbine’s 32,365m2 swept area means at maximum 11MW output, the MySE 11-203 has a specific power rating of 339W/m2 — lower than the rating of Siemens Gamesa Renewable Energy’s recently unveiled 14MW machine (362W/m2) and MHI Vestas’ 10MW turbine (473W/m2), but higher than that of GE’s 12MW Haliade-X (316W/m2).

MingYang claims that the turbine’s compact structure will reduce the load on its drivetrain and will ensure that the components inside the nacelle are guarded against corrosion from salty sea air.

It added that the MySE 11-203 is due to have a 31% higher annual energy production than its predecessor, the MySE 8.3-180. 

The manufacturer has developed its series of hybrid-drivetrain turbines — which also features 5.5MW and 7.5MW models — with German engineering firm Aerodyn.

MingYang stated that it aims to become the “leading global player of offshore wind in the long term”.

However, to date, all of its installations and orders are off its native China, according to Windpower Intelligence, the research and data division of Windpower Monthly.

The company has recently established a business and engineering centre in Hamburg, Germany, as part of a drive into European markets, the manufacturer explained.

With the MySE 11-203, Chinese OEM MingYang is the fifth company to offer a 10MW-plus turbine. Compatriot  Dongfang is due to install a prototype of its 10MW D10000-185 model soon, Siemens Gamesa recently unveiled its SG14-222, MHI Vestas has its V164-10.0MW, and GE offers the 12MW Haliade-X.
