Atlas Copco has equipped a QES 60 energy generator for the profitable set up of the world’s first 16-MW offshore wind turbine, in southeast China’s Fujian Province. Atlas Copco’s accomplice within the area, Chengdu Shiwei Expertise Corp., delivered this dependable QES energy generator to supply the crucial energy provide wanted for the spreader to put in the three giant turbine blades.
In accordance with the Nationwide Bureau of Statistics, in 1H23, China’s complete generated energy reached 4.17 trillion kWh, up 3.8% y/y, with wind energy growing 16% y/y.
As a part of the nation’s dedication to sustainability, China has invested in and constructed the world’s largest offshore wind farm by way of single-unit capability, within the Fujian province. The wind farm, which is situated roughly 35 km offshore from Pingtan, consists of 11 offshore wind turbine models, together with the world’s largest 16-MW offshore wind turbine unit. The full put in capability of the wind farm reaches 111 MW.
The 16-MW offshore wind turbine is 152 m excessive and consists of the world’s longest turbine blades at 123 m, and every blade weighs 54 t. The full swept space of the three blades is roughly 50 000 m2, which is equal to the realm of seven standard-sized soccer fields.
At full wind velocity, the wind turbine can generate 34.2 kWh of energy after one full rotation. Its annual energy output is estimated to common over 66 million kWh and is predicted to satisfy the annual demand of 36 000 three-person households, saving 22 000 t of normal coal, and decreasing 54 000 t of carbon dioxide.
The set up was facilitated by China’s most superior self-lifting and self-propelled built-in wind energy set up platform Baihetan, with a lifting capability of 2000 t. Nevertheless, the set up of such a big turbine was no simple feat, and the turbine’s huge measurement prompted vital challenges.
The altitude and the marine setting additionally made this challenge extraordinarily complicated. Moreover, the wind-exposed floor space of the turbine will increase with every blade added. Because of this, the third blade needed to be put in in a single operation with out interruption to make sure the general stability of the construction. This required explicit calls for from the generator.
“The humidity and salty sea air may simply corrode the machines, so the gear wanted to have the ability to face up to these circumstances,” stated Winston Wang, Product Specialist Energy & Gentle at Atlas Copco in Shanghai. “Moreover, the blades had been docked at a top of 100 m, and dealing at such a excessive altitude required gear with a remote-control operate. Lastly, on this utility, downtime would symbolize an enormous loss, and the soundness and sturdiness of the mills had been important.”
Chengdu Shiwei Expertise Company really useful Atlas Copco’s QES 60 energy generator as they knew it will be capable to function reliably in these difficult circumstances. The QES 60 was excellent for the appliance as it will possibly face up to harsh parts and is provided with a distant operation and monitoring system. Operators can instruct the unit from a distant platform, monitoring the mills’ efficiency and overseeing the method remotely.
The QES 60 energy generator was additionally modified barely to satisfy the client’s particular wants.
“This QES generator set was specifically designed with a big capability tank in order that it may work constantly for greater than 24 hours with out fail, subsequently offering the reliability and stability wanted,” defined Wang. “Moreover, the waterproof cover underwent a C5M coating and portray course of to supply greater corrosion resistance in comparison with typical fashions. The generator was additionally outfitted with an anti-condensation heater to enhance the anticorrosion and moisture resistance of {the electrical} core elements.”
The set up of the huge offshore wind farm marks a breakthrough in high-end wind turbine manufacturing and deep-sea offshore wind energy development capabilities.
“The efficient setup and utilisation of the wind turbine represents a major achievement in advancing China’s offshore wind energy trade towards intensive offshore innovation,” commented Fangjian Xie, Venture Supervisor at Chengdu Shiwei Expertise Corp.
Globally, put in offshore wind capability reached 63.2 GW by the top of 1H23, 45% of which (28.7 GW) is now put in in China, in line with the annual report revealed by trade physique World Discussion board Offshore Wind (WFO). Moreover, the nation gives almost 60% of worldwide wind turbine gear. China’s progress continues, with 2.2 GW of newly put in capability throughout 1H23.
“The 16-MW offshore wind turbine is predicted to spice up the event of China’s offshore wind energy trade even additional, and Atlas Copco is proud to be contributing in the direction of the optimisation of renewable power utilization,” concluded Wang.
