The hidden machine<\/h2>\n\n\n\n
The Three Gorges Rudong converter station was described as the world\u2019s largest and Asia\u2019s first offshore converter station when it was installed in 2021. It weighed about 24,250 tons and stood about as high as a 15-story building. That is not exactly the kind of equipment you just lift into place.<\/p>\n\n\n\n

The station collects power from the Rudong H6, H8 and H10 wind farms, converts it into direct current, and sends it to shore with fewer losses than a long alternating-current link would normally face.<\/p>\n\n\n\n
Why direct current matters<\/h2>\n\n\n\n
When offshore wind farms move farther from the coast, the grid problem gets bigger. Alternating current can lose more energy over long submarine cable<\/a> routes, especially when large amounts of electricity must travel many miles before reaching land.<\/p>\n\n\n\nThat is where flexible high-voltage direct current technology comes in. Think of it as swapping a leaky bucket for a tighter pipe. The electricity still has a long trip, but more of it arrives where people actually need it.<\/p>\n\n\n\n
A giant engineering bet<\/h2>\n\n\n\n
The station\u2019s size forced engineers to avoid a standard crane lift. China Three Gorges said the platform was so heavy that even the world\u2019s largest lifting vessels at the time could not handle the job, so crews used ballast systems and natural tides to position it.<\/p>\n\n\n\n
That may sound like a detail for engineers only, but it isn\u2019t. At the end of the day, better installation methods can decide whether offshore wind<\/a> becomes a niche project or a repeatable industrial model.<\/p>\n\n\n\n![\"A](\"https:\/\/okdiario.com\/techy\/en\/wp-content\/uploads\/2026\/06\/china-offshore-wind-converter-platform-1.jpg\" "\\"\\"")
By converting wind energy to high-voltage direct current, these massive offshore stations allow massive amounts of power to travel long distances under the sea with minimal energy loss.<\/figcaption><\/figure>\n\n\n\nThe climate math<\/h2>\n\n\n\n
There is a small caveat in the household figures. China Classification Society said the full project could meet the annual electricity needs of about 1.36 million households, while China Three Gorges Renewables<\/a> put annual generation at 2.4 billion kWh, equal to about 990,000 households. Different household-use assumptions can change the final number.<\/p>\n\n\n\n\n\n\nAlso Read: A 152-wheel truck moved a 302,000-lb. tunnel cutterhead, and the logistics became a second engineering project\u00a0<\/a><\/h4>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\nBy CTG\u2019s own estimate, the Rudong project can also save about 815,700 tons of standard coal and cut about 2 million tons of carbon dioxide emissions each year compared with a coal-fired plant of similar scale.

Rudong was not the end of the story. On June 4, 2026, China Three Gorges said its newer \u201cHeart of Sea Wind\u201d offshore converter station had been installed in Guangdong waters, a larger platform built for the Three Gorges Yangjiang Qingzhou V and VII offshore wind farms.<\/p>\n\n\n\n
That newer station weighs about 27,600 tons and is 144 ft. tall. CTG said it will deliver about 6 billion kWh of clean electricity each year after full operation and reduce carbon dioxide emissions by nearly 5.5 million tons.<\/p>\n\n\n\n
