AS China National Offshore Oil Corp. (CNOOC)’s Liuhua 21-2 oil field has started operation Monday, the deepwater Liuhua 16-2 oil field cluster, located in the eastern South China Sea and 250 kilometers southeast of Shenzhen, is now fully operational.

The Liuhua oilfield cluster includes the development of one 150,000 DWT (deadweight ton) floating production storage and offloading (FPSO), the offshore oil and gas processing plant, as well as the Liuhua 16-2, 20-2 and 21-2 oil fields. The three fields are located in the waters of the South China Sea ranging from 380 to 430 meters deep.

The Liuhua 16-2 and 20-2 oil fields were put into operation in September and October last year, respectively.

The crude oil of the three oil fields is produced underwater and is sent back to the FPSO. The plant, built by CNOOC, named Hai Yang Shi You 119, is designated to handle 50,000 barrels of oil per day. It consists of crude oil and LPG (liquefied petroleum gas) offloading reels, a tandem mooring system, a hydraulic power unit and equipment controls.

The 119 FPSO is installed with a domestically developed light hydrocarbon collection system. With the operation of the Liuhua 21-2 oil field, the daily output of light hydrocarbon will exceed 300 cubic meters.  (SD News)
