World's largest offshore converter station departs from Nantong

The world's largest offshore converter station, the Three Gorges Yangjiang Qingzhou Offshore Converter Station, was dispatched from the wharf of Zhenhua Heavy Equipment Manufacturing in the Nantong Economic and Technological Development Area, East China's Jiangsu province, on May 27.

According to the plan, the converter station will be transported by a semi-submersible vessel to the Yangjiang Qingzhou Offshore Wind Farm in Guangdong province, located 1,090 nautical miles away. There, it will be connected to pre-installed jacket foundations on the seabed.

Constructed by Nantong Zhenhua Heavy Equipment Manufacturing, the converter station is the world's first ±500 kilovolt, 2,000 megawatt flexible direct current offshore converter station.

It boasts 85.5 meters in length, 82.5 meters in width, 44 meters in height, and weighs 25,000 metric tons, presenting a surface area equivalent to a standard soccer field and a height equal to a 15-story residential building.

Upon completion, this facility will utilize advanced flexible direct current technology to bundle and transmit clean energy from offshore wind farms, delivering an estimated 6 billion kilowatt-hours of green electricity annually to the Guangdong-Hong Kong-Macao Greater Bay Area, promoting large-scale offshore wind power development in China and supporting the nation's dual-carbon goals.
