China's Deep Sea No.1 gas field sees key construction progress

Deep Sea No. 1, China's self-developed ultra-deep-water gas field, has seen the onshore manufacturing of its integrated processing platform completed and the platform's jacket put under the sea recently, China National Offshore Oil Corporation (CNOOC) said on Thursday.

The integrated processing platform, made of an underwater jacket and a production module over the sea, is about 136 meters tall and weighs approximately 12,215 tonnes, heavier than 8,000 cars.

The jacket with eight legs and 12 skirt piles was completed onshore in Shenzhen of south China's Guangdong Province in mid-January. The offshore production module owns a 57.5-meter-long and 36-meter-wide deck.

The platform is equipped with multiple sets of domestically produced equipment with full independent intellectual property rights, including a 7-megawatt combustion turbine generator.

It is also equipped with the country's largest offshore platform slug flow catcher independently developed by CNOOC, which is used to eliminate the risk of liquid level fluctuation and blockage of oil and gas mixed transport pipelines and ensure the reliable operation of oil and gas treatment equipment.
