China is preparing to completed its self-developed deep-water offshore liner installation, the highest in Asia, on Sunday, marking a significant technological breakthrough in the country’s design and development of such infrastructure.

This jacket, dubbed “Haiji No. 1”, supports an offshore oil and gas drilling platform. It is the first jacket that can be used in 300-meter deep waters in Asia, and has a height of 302 meters and a weight of 30,000 tons.

Sitting 284 meters deep in water, “Haiji No. 1” will operate in the eastern South China Sea, 200 kilometers southeast of the Hong Kong Special Administrative Region. It is the first time for China to develop and install a fixed jacket in this sea area, and it is expected to boost development in the Guangdong-Hong Kong-Macao Greater Bay Area.

Serving as the base for a fixed offshore oil and gas platform, the jacket will carry a platform weighing 11,000 tons with a deck area of ​​7,700 square meters, the heaviest in the country.

The volume of steel used for the structure is enough to make a medium-sized aircraft carrier, according to Science and Technology Daily.

There are thousands of oil and gas rigs around the world, but only 10 are designed to operate below 280 meters.

The installation of “Haiji No. 1” was completed nearly two years after construction began in March 2020.
