NOTE: The next article has been revised following an announcement from Mingyang Good Power.
On December 13, Mingyang Good Power launched an announcement in response to reviews of two blades breaking off its 20 MW offshore wind turbine prototype positioned in Hainan, China. The corporate clarified that the wind turbine was subjected to excessive testing situations, which resulted within the blades experiencing hundreds past their design limits in the course of the trials.
Reviews point out that the blade failure incident occurred on December 6 and concerned the MySE18.X-20MW prototype.
In an e mail to offshoreWIND.biz, Mingyang Good Power said: “Lately, photographs have circulated on-line exhibiting fractures within the blades of Mingyang wind generators. These photographs depict a prototype at present present process testing at our giant turbine take a look at middle in Lingao, Hainan. The turbine was subjected to excessive situations, a vital step to make sure that our new fashions meet rigorous requirements for reliability and efficiency. It is very important observe that this product continues to be within the testing part and has not but been commercially launched. Luckily, no personnel had been harmed on the take a look at website.”
The corporate additional defined through social media on December 13 that its evaluation of the testing knowledge led to a preliminary conclusion: the wind turbine confronted excessive and irregular testing situations, which brought on the blades to exceed their design load limits and subsequently fail.
“Excessive testing is an important side of our progressive analysis and improvement course of. We are going to proceed to boost our in-depth analysis on the product’s adaptability below such low-probability situations to enhance its performance and guarantee superior, safer, and extra dependable efficiency,” said Mingyang.
Particulars concerning the particular prototype that skilled blade failure weren’t disclosed by the corporate.
Concerning the MySE 18.X-20 MW prototype, Mingyang manufactured the nacelle at its Shanwei facility in December 2023 and carried out the turbine on the onshore take a look at website in August of the identical 12 months.
At its announcement, Mingyang declared this prototype because the world’s largest single-capacity offshore wind turbine, able to versatile energy scores between 18+ MW and 20 MW, together with rotor diameters starting from 260 to 292 meters.
With a mean wind pace of 8.5 m/s, this mannequin can generate roughly 80 million kWh per 12 months, which offsets about 66,000 metric tons of CO2 emissions, equal to the annual vitality consumption of round 96,000 households, as beforehand shared by the producer.
Mingyang additionally indicated that the turbine is engineered for world deployment in areas experiencing medium to excessive wind speeds and is particularly designed to resist typhoons with gusts of as much as 79.8 m/s.
