China has created a new model in deepwater oil and gas extraction with the completion of two offshore facilities in the Pearl River Mouth Basin, about 240 kilometers southeast of south China’s Shenzhen City, China Media Group reported on Tuesday.

The two facilities, including Haikui No. 1, Asia’s first cylindrical floating oil-gas production, storage and offloading (FPSO) facility, and Haiji No. 2, Asia’s largest deepwater jacket structure, are making oil and gas extraction offshore more efficient.

Haiji No. 2 is responsible for the extraction of crude oil from the seabed, while Haikui No. 1 provides power for Haiji No. 2. in addition to handling the production, storage and offloading of oil and gas. 

“This extraction model can greatly raise the recovery rate and extend the production life of the oil field by nearly 30 years, providing a new option for the efficient development of deepwater oil and gas fields in China,” said Yu Hongkun, a production manager of the oilfield.

Developed by China’s largest offshore oil producer, China National Offshore Oil Corporation (CNOOC), the combo is part of the secondary development project of the Liuhua Oilfield.

With a weight of 37,000 tonnes and a height of nearly 30 stories, Haikui No. 1 has a maximum oil storage capacity of 60,000 tonnes, and it can operate continuously at sea for 15 years without returning to dock. With a height of 428 meters and a weight of over 50,000 tonnes, the home-grown Haiji-2 jacket has set Asian records for structure height, weight, operational depth and construction speed.
