Haiji 1 is the first deepwater jacket designed and built by China in Asia. The construction of Haiji-1 indicates that China has successfully opened up a new mode of oil and gas development for deepwater fixed platforms. The design, construction and installation capacity of deepwater super-large jacket platform has reached the world-class level, which is of great significance for promoting offshore oil and gas storage and production and ensuring national energy security.
China Offshore Oil Corporation co-ordinates high-quality resources at home and abroad, organizes technical research, and innovatively puts forward the design and construction scheme of 300m deep-water jacket, which overcomes a series of technical problems such as the overall design of super-large jacket and the joint hoisting of large-size large-span large-tonnage structures by multiple cranes, fills many technical gaps in the design and construction of super-large deep-water jacket in China, improves the technology and management system of jacket design and construction, and applies the digital twin health management technology for the first time, which provides a strong guarantee for the safe operation and maintenance of jackets.
Development history of Haiji-1
On February 28th, 2022, CNOOC China announced that Haiji-1 was successfully completed in Zhuhai, Guangdong. On March 15, 2022, the "Haiji 1" jacket, which was generally contracted by Offshore Oil Engineering Co., Ltd., successfully boarded the designated position of the transport barge at the wharf of Zhonghai Fulu site in Zhuhai, Guangdong Province, marking the completion of the onshore construction of the deepwater jacket independently designed and built by China.
On April 1 1 day, 2022, the first deepwater jacket in Asia, "Haiji 1", built by CNOOC Shenzhen Branch, successfully slipped into the water in Lufeng Oilfield and located it accurately, setting a new record for offshore installation of deepwater jackets in Asia. On April 25th, 2022, CNOOC China announced that the main project of Haiji-1 Platform, the first deepwater jacket platform in Asia designed and built by China, had been installed at sea.
On May 24th, 2022, Haiji No.1, the first deepwater jacket platform in Asia designed and built by China, was installed at sea in the Pearl River Mouth Basin, which is more than 200 kilometers southeast of Shenzhen with a water depth of about 284 meters. In July 2022, the first deepwater jacket platform in Asia "Haiji No.1" was mechanically completed, and the whole set of production equipment had production conditions. On August 7, 2022, the first deepwater jacket platform in Asia "Haiji No.1" officially started drilling.
