【Major Chemical Equipment in a Major Country】099 – Asia’s deepest 300-meter jacket structure, “Haiji No.1””
Thread Content
The past decade has been a period of rapid development in China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share their insights and engage in discussions, to cheer for Made in China and to support the development of chemical processing equipment! *********************************** On April 11, 2022, China National Offshore Oil Corporation (CNOC) announced that the \"Haiji-1\" platform, Asia’s first deep-water jacket designed and built in China, was successfully lowered into position in the waters of the Pearl River Delta basin in the eastern South China Sea. This achievement set a new record for the offshore installation of deep-water jackets in Asia, indicating that China has reached world-class levels in key technologies and installation capabilities related to deep-water, super-large-scale jackets. It holds great strategic significance for enhancing oil and gas reserves and production offshore, as well as ensuring energy security.
We welcome more people to participate in these discussions in order to support China’s chemical industry and praise its equipment manufacturing sector.

“The “Haiji-1” platform is located on the main pathway of internal wave currents in the South China Sea, and offshore installation imposes very high requirements on the operational weather conditions as well as on on-site command. To ensure the safe and efficient conduct of offshore operations, the project deployed the Asia’s top-grade crane ship, the \"Blue Whale,\" as the main working vessel. It made innovative use of advanced technologies such as internal wave flow warning systems and vessel motion monitoring to overcome challenges related to large-amplitude internal wave flows and slow vessel drift. As a result, the horizontal positioning accuracy for offshore installations reached 10 millimeters, with a horizontal deviation of 1.5 meters – values that far exceed the design requirements. Yang Lianfeng, the general manager of the general contracting project for the regional development of the Lufeng oilfield complex of CNOOC, explained. It is understood that the “Haiji-1” platform is a multi-functional drilling and production platform that integrates drilling, production, and living facilities, and is equipped with equipment such as a crude oil processing system and South China Sea’s first advanced treatment system for producing water intended for reinjection. The total height of the platform is 340.5 meters, exceeding that of the Beijing Guomao Building; its deck area is 7,700 square meters, about 1.1 times the size of a standard football field. With a total weight of nearly 40,000 tons, it will set a new record for the heaviest single offshore crude oil production platform in China once completed. To reduce operational risks, improve construction efficiency, and minimize offshore construction activities, the \"Haiji-1\" platform adopts an integrated construction approach, with an integration rate of 93% for onshore construction, and all key equipment is domestically produced. Considering factors such as water depth, technology, investment, and construction time, marine oil and gas development adopts various models. The jacket platform development model is the most widely used format globally, and it is typically employed for the exploitation of oil and gas resources in shallow waters. Previously, in China’s waters at 200 meters depth and greater, the development model of \"floating production platforms + subsea production systems\" was used. “The “Haiji-1” platform represents China’s first attempt at using the deep-water jacket platform development model; it can reduce development costs by approximately 15%, and it will also significantly cut subsequent drilling, completion, and production expenses, thereby improving the oil field’s recovery rate and economic viability. Gao Shuang, project manager for the regional development of the Lufeng oilfield complex at CNOOC, said that its successful application has opened up a new path for the economic and efficient exploitation of oil and gas resources in China’s medium and deep-water areas. “The “Haiji-1” platform is deployed for the development project of oilfield clusters in the eastern part of China’s South China Sea, and is scheduled to come online in the second half of this year. Once the oil field complex is fully operational, it will be able to produce up to 6,500 tons of crude oil per day at peak times, thereby providing new impetus for the economic and social development of the Guangdong-Hong Kong-Macao Greater Bay Area and further enhancing China’s energy security.
