A look at some of China's mega engineering marvels

From the depths of the ocean to the skies above, China's advances in engineering are reshaping the nation's technological landscape.

In 2024, two offshore giants, the Haiji-2 deepwater jacket platform and the Haikui-1 cylindrical FPSO facility, were launched. Standing 428 meters tall and weighing over 50,000 tons, Haiji-2 integrates drilling, production, and living facilities. Meanwhile, Haikui-1, Asia's first cylindrical floating production, storage and offloading facility, can store up to 60,000 tons of oil and process about 5,600 tons of crude oil daily.

On land, the Shendi Take 1 ultra-deep well in Xinjiang's Tarim Basin reached a depth of 10,910 meters in February 2025, making it the deepest vertical well in Asia. In transportation, the Fuxing bullet train continues to bridge regions. With a commercial service speed of 350 km/h (217 mph), it remains one of the fastest conventional high-speed trains in regular service worldwide.

In the skies, the AG600M "Kunlong" amphibious aircraft, designed for firefighting and water rescue, marks a leap in emergency response capabilities. It can scoop up 12,000 kilograms of water in just 20 seconds. And far out at sea, China's first domestically built deep-sea drilling vessel, the Mengxiang, is capable of drilling as deep as 11,000 meters beneath the ocean floor.

Together, these innovations form a vivid portrait of China's pursuit of technological self-reliance.
