Beijing, June 5: The world’s largest offshore converter station, named “Haifang Qishin,” has reached the Qingzhou offshore wind farm in Yangjiang, Guangdong province, China, after a journey of over a thousand nautical miles. Its offshore buoy installation is set to commence.
The large semi-submersible vessel, equipped with “Haifang Qishin,” arrived at the pre-determined offshore installation site after a week of sailing. The converter station will be installed on a pipe rack and will remain at sea.
“Haifang Qishin” is reported to be the world’s first ±500 kV/2000 MW flexible DC offshore converter station. Its footprint is comparable to that of a standard football field, standing approximately 15 stories tall and weighing 25,000 tons. Due to its heavy weight, advanced international integrated floating installation technology will be utilized for its setup.
Once installed, the station will collect, boost, and convert electricity generated by 163 wind turbines from the fifth and seventh phases of the Three Gorges Project’s Yangjiang Qingzhou offshore wind farm from AC to DC. This electricity will then be transmitted to the terrestrial power grid via submarine cables, with an annual capacity to deliver around 6 billion kilowatt-hours of electricity.
