China News Service, Beijing, January 14 (Du Guiting and Wang Enbo) China National Offshore Oil Corporation (hereinafter referred to as "CNOOC") announced on the 14th that the world's first 100,000-ton deep-water semi-submersible production and storage facility independently developed and constructed by China The oil platform-"Deep Sea No. 1" energy station was delivered and set sail in Yantai, Shandong. China's deepwater oil and gas field development capabilities and deepwater offshore engineering equipment construction level have made major breakthroughs.
According to reports, the "Deep Sea No. 1" energy station will be towed by three high-horsepower tugboats from the Yellow Sea all the way south, and arrive in the Nanlingshui area of Hainan Island in February to implement on-site installation of oil and gas production facilities for the development of China’s first A 1,500-meter deep water self-operated large gas field-Lingshui 17-2 gas field.
The "Deep Sea No. 1" energy station is composed of two parts: the upper module and the hull. It is constructed in accordance with the high-quality design standard of "30 years without re-docking for overhaul". The design fatigue life reaches 150 years, and it can withstand the once-in-a-century super typhoon.
The energy station is equipped with nearly 200 sets of key oil and gas processing equipment, and is the world's first semi-submersible platform for column oil storage, with a maximum oil storage capacity of nearly 20,000 cubic meters, realizing the integrated functions of condensate production, storage and export.
The “Deep Sea One” energy station is huge in size, with a total weight of more than 50,000 tons. The maximum projection area is equivalent to the size of two standard football fields. The total height is 120 meters, which is equivalent to a 40-story building. The maximum displacement is 110,000 tons, which is equivalent In 3 medium-sized aircraft carriers.
The total length of the welding seam of its hull engineering is as high as 600,000 meters, which can circle Beijing Sixth Ring Road 3 times; the cable length exceeds 800 kilometers, which can circle Hainan Island for one week.
You Xuegang, general manager of the CNOOC Lingshui 17-2 gas field development project, said that the "Deep Sea One" energy station has achieved 3 world-class innovations during the construction phase, and used 13 domestic first technologies to overcome more than 10 industry problems. A masterpiece in the field of China's offshore engineering construction.
The "Deep Sea No. 1" energy station will carry out the installation and commissioning of oil and gas production facilities in the Lingshui area for more than 4 months, and it is expected to be ready for operation in June this year.
After the Lingshui 17-2 gas field is put into operation, it will rely on the main artery of the offshore natural gas pipeline network to supply 3 billion cubic meters of deep-sea natural gas to Guangdong, Hong Kong, Qiong and other places each year, which can meet a quarter of the residential gas demand in the Guangdong-Hong Kong-Macao Greater Bay Area.
