In a significant leap for renewable energy infrastructure, the world's largest offshore converter station, aptly named the "Heart of Offshore Wind," has arrived at its installation site in Yangjiang, Guangdong Province of the Chinese mainland. This monumental project marks a new milestone in the global transition toward sustainable power.
The "Heart of Offshore Wind" is a technological marvel, standing as the world's first ±500-kilovolt, 2,000-megawatt flexible DC offshore converter station. To grasp its scale, the station's deck covers an area nearly equivalent to a standard football field and rises as high as a 15-story building. Weighing approximately 25,000 tonnes, the facility is designed to handle massive energy loads with unprecedented efficiency.
Given its immense weight, which exceeds the lifting capacity of existing domestic marine crane vessels, engineers are employing a sophisticated "float-over" installation method. This internationally recognized technique allows for the precise positioning of massive offshore structures, ensuring stability and safety during the deployment process, which is scheduled to commence this Thursday.
Once operational, the converter station will serve as the central hub for the Phase V and Phase VII sections of the Three Gorges Yangjiang Qingzhou offshore wind farm. It will collect and step up alternating current (AC) generated by 163 wind turbines, converting it into direct current (DC) for efficient transmission to the onshore power grid via high-capacity subsea cables.
The impact of this project is substantial. The facility is expected to deliver approximately 6 billion kilowatt-hours of clean electricity annually, providing a vital boost to the renewable energy supply of the Chinese mainland and contributing to long-term carbon reduction goals.
