In 1964, China’s offshore oil and gas industry started in the Bohai Bay. The older generation of petroleum overcame extreme difficulties, independently completing the design, construction and installation of China’s first fixed offshore drilling platform, “Sea 1”, in 1966, marking the beginning of China’s offshore oil and gas development equipment fabrication.
In 1975, China’s first comprehensive offshore oil production platform, “Sea 4” was completed and put into operation. From 1964 to 1977, the Company delivered 20+ platforms for offshore oil and gas exploration and development

In 1978,Chinese government made a significant decision to “Open up China’s offshore oil and gas industry to the world”. The Company began to learn management, technologies, techniques, nurture talents and build a team through international cooperation, facilitating the rapid integration of offshore oil and gas engineering with international standards.
In 1985, Chengbei Oilfield Development Project was completed and put into production, which was the first offshore platform designed according to the international standards and codes. That same year, the project received “the National Award for Science and Technology Progress”. Through project implementation, an entire set of internationally advanced management practices was developed, covering from the feasibility study of oilfield development to the completion and operation of the oilfield.
During that time, the Company completed 30+ jackets and SPMs, 50+ topsides and skids, 200+km subsea pipeline according to the international standards and technical specifications
