Offshore Installation of Asia's First Deepwater Jacket Completed

Offshore installation of the Haiji One, Asia's first deepwater jacket independently designed and built by China National Offshore Oil Corporation (CNOOC), was completed on May 24.

With a total weight of nearly 40,000 metric tons, the platform is currently the heaviest single crude oil production platform in China.

It is the first jacket platform to be designed, built and installed in 300-meter deepwater areas in China, which marks that the country has mastered the key technologies of manufacturing and installation of ultra-large jacket platforms.
