China News Service, Beijing, May 29. China National Offshore Oil Corporation ("CNOOC") announced on the 29th that the world's first 100,000-ton deep-water semi-submersible production and storage platform-"Deep Ocean One" Energy The station has successfully completed the installation of all equipment, which means that the underwater and surface production facilities of the energy station have been connected, and the entire production facility has been put into operation.

  CNOOC stated that this once again verified the advanced nature and reliability of China's independent deepwater oil and gas development technology system and large-scale deepwater oil and gas core equipment, and marked an important step forward for China's deepwater oil and gas resource development capabilities.

  It is understood that the "Deep Sea No. 1" energy station set off from Yantai, Shandong Province in mid-January this year. It took 18 days and sailed more than 1,600 nautical miles. 17-2), start the offshore mooring, installation and production commissioning work.

At present, the "Deep Sea No. 1" energy station is stepping up the final joint commissioning of equipment before it is put into operation.

  The “Deep Sea No. 1” energy station is used to develop the “Deep Sea No. 1” large gas field, which was discovered in the south Lingshui area of ​​Hainan Island in August 2014. The maximum water depth exceeds 1,500 meters. This is the first deep-water exploration in China’s seas. A major oil and gas discovery.

At the end of 2018, CNOOC officially launched the substantive engineering construction of the gas field, and the development plan adopted the model development of "semi-submersible production platform + underwater production system + submarine pipeline".

  According to You Xuegang, general manager of the CNOOC Lingshui 17-2 project team, the difficulty of developing the "Deep Sea No. 1" large gas field and the complexity of construction and installation of production facilities are second to none in the field of offshore oil development.

During the construction and installation of the "Deep Sea One" energy station, it adopted three world-class innovations and 13 domestic first-in-class technologies, breaking through 12 "stuck neck" technologies, and became a masterpiece in the field of China's offshore engineering equipment, breaking the world The construction speed of the same type of platform is the fastest.

  The "Shenhai No. 1" large gas field is expected to be officially put into operation at the end of June this year, with a peak annual gas production of more than 3 billion cubic meters. Through the surrounding Hainan Island, connecting Guangdong and Hong Kong submarine pipelines to the Guangdong-Hong Kong-Macao Greater Bay Area and the Hainan Free Trade Port. The land transports clean energy from the deep sea, which can meet a quarter of the residential gas demand in the Greater Bay Area and become a new energy supply center in the South China Sea.
