Great news, China's deepwater oil and gas field development capabilities have made major breakthroughs. On January 14, 2021, the "Deep Ocean One" energy station was delivered and set sail in Yantai, Shandong. The world's first 100,000-ton deep-water semi-submersible production and storage platform independently developed and built by China was born and immediately attracted the attention of many media .

The completion and delivery of "Deep Sea One" has enabled China's offshore oil industry to add deep-water heavy equipment, marking a major breakthrough in China's deep-water offshore engineering equipment construction level, and improving China's marine resource development capabilities, ensuring national energy security, and practicing as a maritime power Strategy is important.

"Deep Sea No. 1" is a deep-water production operation platform with the functions of oil and gas processing, condensate oil storage and oil and gas export. It consists of two parts, the upper block and the hull, and is in accordance with the high-quality design standard of "30 years of non-docking maintenance" Built and designed with a fatigue life of 150 years, it can withstand the once-in-a-hundred-year super typhoon.

"Deep Sea One" achieved 3 world-class innovations in the construction phase, used 13 domestic first technologies to overcome more than 10 industry problems; a number of deepwater construction technologies broke through the 1,500-meter difficulty, and fully mastered more than 10 types of water Independent manufacturing technology for key equipment.

"Design in China", "Build in China" and "Innovation in China", "Deep Ocean One", which wears many labels, is also a classic sample in the field of offshore engineering construction.

Epidemic challenges, breaking records

During the critical period of construction and towing preparations, the project team encountered severe challenges brought by the new crown pneumonia epidemic. CNOOC adheres to the two-handed approach to epidemic prevention and production, adopts a number of QHSE management innovations and dynamics, and full-process risk control, such as flat organization, intelligent personnel positioning, and grid safety management. During the peak period of operation, more than 4,000 people are safely organized to fight day and night. , Achieved impressive results of 17 million working hours without accidents, shortened the project duration to 21 months, and set the international record for the shortest construction time for projects of the same scale.

CNOOC’s Party Secretary and Chairman Wang Dongjin said that in the extraordinary 2020 project team, the project team has always insisted on the goal of putting into production. It will not wait for time and take responsibility to fulfill the mission of key milestones and create "CNOOC speed". "Lingshui Miracle" has achieved a new breakthrough in the independent development of China's South China Sea oil and gas, and has interpreted CNOOC's responsibility to ensure national energy security with practical actions.

Looking to the future, CNOOC will further increase oil and gas exploration and development and scientific and technological innovation, vigorously promote the "seven-year action plan" for increasing domestic oil and gas reserves and production, and strive to become the main force in increasing domestic reserves and production.
