The offshore float-over installation of the world's largest offshore converter station, known as "Heart of the Sea Wind," has been completed off Yangjiang in south China's Guangdong Province after a 1,090-nautical-mile journey from Nantong, Jiangsu Province. The 25,000-tonne upper module was precisely connected with its underwater jacket foundation, moving the project into full commissioning before operation. Once in service, the station will collect electricity from 163 offshore wind turbines, step up the voltage, convert it into high-voltage direct current and transmit about 6 billion kilowatt-hours of green power to the onshore grid each year.
