The largest displacement of the offshore oil industry is comparable to 3 medium-sized aircraft carriers

On January 14, China National Offshore Oil Corporation (hereinafter referred to as “CNOOC”) announced to the public that the world’s first 100,000-ton deepwater semi-submersible production and storage platform-“Deep Sea No.1” independently developed and built by China, the energy station was successfully delivered and set sail for offshore oil industry.

The “Deep Sea No. 1” energy station will be driven by three high-horsepower tugboats from the Yellow Sea all the way south, and arrive in the southeast Lingshui area of ​​Hainan Island in February to implement on-site installation of oil and gas production facilities for the development of my country’s first 1,500-meter The deepwater self-operated large gas field—Lingshui 17-2 gas field is expected to be ready for production in June this year.

After the 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 Greater Bay Area.

Stainless steel pipe and fittings supplier, KAYSUNS understands that 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 back-to-docking” and has a design fatigue life of 150 years, which can withstand once-in-a-century encounter The super typhoon. The energy station is equipped with nearly 200 sets of key oil and gas processing equipment. At the same time, it is the world’s first semi-submersible platform to store oil with a maximum oil storage capacity of nearly 20,000 cubic meters. It has realized the integrated functions of condensate production, storage and export, and has good performance The economic benefits and technical advantages.

The “Deep Sea No. 1” 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, equivalent to a 40-story building, and the maximum displacement is 110,000 tons. It is equivalent to 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 3 times; the cable length exceeds 800 kilometers, which can circle Hainan Island for one week.

According to You Xuegang, general manager of the “CNOOC Lingshui 17-2 Gas Field Development Project”, the project has achieved 3 world-class innovations during the construction phase, used 13 domestic first technologies, and solved more than 10 industry problems. A masterpiece in the field of construction.
