Nanhai No.8 has a maximum operating depth of 1400m and a maximum drilling depth of 7620m, and its operating capacity is second only to "Offshore Oil 98 1" in China. 201February 5, 12, Nanhai No.8, an upgraded deepwater semi-submersible drilling platform, stood proudly at the dock of Shenzhen Island and officially joined the deepwater fleet of CNOOC China.
Nanhai No.8 deepwater drilling platform
The "Offshore Oil 98 1" designed according to the ultra-deep water standard is not suitable for operation in the sea area with a water depth of less than 800 meters, while the water depth of other in-service drilling platforms in China is less than 450 meters ... The application of "Nanhai No.8" has optimized the drilling equipment structure of China Offshore Oil Corporation and can meet the domestic demand for oil and gas exploration and development with a water depth of 450 ~ 800 meters.
The commissioning of Nanhai No.8 platform will further enhance the deepwater drilling capacity of China Offshore Oil Company and fill the gap of domestic drilling equipment in the water depth of 450-800 meters.
On March 1 2003, Nanhai No.8 drilling platform successfully completed the downhole blowout preventer operation of a deep water well in Liu Hua Oilfield, with a water depth of 546m, which was the first deep water well operation of Nanhai No.8.
