Chinese wind turbine maker eyes Europe with largest system

The MySE 16.0-242 has 118m long blades and a 242m diameter, covering 46000m2 swept area equivalent of more than six soccer fields. This compares to the 260m high 15MW turbine with a 236m diameter from Vestas in Denmark. The previous record was held by GE’s 14MW Haliade-X, with a 220m diameter.

The size means a single turbine can produce 16MW, or 80000MWh of electricity every year, enough to power more than 20000 households. This is 45 percent more energy than MingYang’s previous turbine model, the MySE 11.0-203.

The company is targeting all mainstream offshore wind markets including Europe, particularly around the UK, and has set up a business and engineering centre in Hamburg, Germany. It is also exploring developing overseas manufacturing facilities.

The turbine is scheduled for full prototype rollout in 2022, to be followed by prototype installation in the first half of 2023 and commercial production in the first half of 2024.

MingYang has previously built multiple smaller, light-weight offshore models, ranging from 5.5MW, 6.45MW, 7.25MW, 8.3MW to 11MW series.

The nacelle weight of the MySE 16.0-242 is relatively low at under 37 tonnes per MW. Compared to a heavier nacelle, this lower mass allows for more efficient use of the tower and foundation construction, resulting in fewer materials and logistics. This also allows all the power electronics and MV-transformer to be relocated up into the nacelle, simplifying cabling and enhancing system maintenance. An air-tight design protects the nacelle from salt spray corrosion but still provides internal natural air cooling for the power electronics.

The Hybrid-Drive transmission technology uses load sharing  and forced high precision main bearing lubrication for both bottom-fixed and floating turbine systems.

“The launch of our new largest wind turbine, MySE 16.0-242, is an apt illustration of the three essential drivers to technology evolution – demand, combination and iteration,” said Qiying Zhang, President and CTO of Ming Yang Smart Energy. “In response to demand for anti-typhoon wind turbines in coastal Guangdong, MingYang systematically develops high-quality products by collaborating with global supply chain partners and integrating cutting-edge technologies from industries such as aerospace, materials, and big data.”

“Over the years, we have gained over 10GW cumulative track record and iteration experience with Hybrid-Drive technology. These enable us to have a rapid learning curve in product R&D and position us well to become an offshore wind leader,” he said.
