Tianjin, July 8, China News Service — (Wang Zaiyu, Wang Junyan) On the 8th, reporters learned from CNOOC Tianjin Branch that the first domestically developed prototype of a shallow-water subsea production manifold in China has been successfully installed in the Bohai Sea. This marks a new breakthrough in China’s independent research, development, manufacturing, integrated testing, and installation of subsea production equipment for offshore oil and gas. Underwater oil and gas production manifolds are primarily located between the wellheads on the seabed. They perform a range of important functions, including gathering oil and gas from the wellheads, distributing electricity and hydraulic power, as well as enabling underwater control and monitoring. Often referred to as underwater \"oil and gas hubs,\" they are among the key technical equipment for the development of underwater oil and gas fields. “This is the first demonstration project in the Bohai Sea to adopt an underwater development approach. Over the past three years, we have combined research with production to establish a new development model characterized by ‘no facilities on the surface, but large-scale production underwater’, a model that fosters cooperation among various parties. This approach has provided strong impetus for boosting oil and gas production in the special areas of the Bohai Sea, with the goal of increasing output there by 40 million tons. ”Shen Liubing, project manager at the Engineering Construction Center of CNOOC Tianjin Branch, said.

Underwater manifolds are mainly located between the wellheads on the seabed, and they perform a range of important functions such as gathering oil and gas from the wellheads, distributing power and hydraulic pressure, as well as enabling underwater control and monitoring. They are referred to as underwater \"oil and gas hubs\" and represent one of the key technical components in the development of underwater oil and gas fields. Due to a late start, China has yet to make breakthroughs in the independent design and manufacturing of overall design technologies and key components for underwater production manifolds. Faced with stringent technical requirements, the project team composed of the Engineering Construction Center of CNOOC Tianjin Branch and CNOOC Engineering carried out intensive research on key technologies, developing a set of core technologies for the independent design, manufacturing, testing, and engineering application of shallow-water production manifolds. They were also successful in independently developing and manufacturing key core components for underwater products such as horizontal connectors and valves.

As an underwater \"oil and gas hub\" and one of the core technical equipment for the development of deep-water oil and gas fields, today (the 6th), China’s first set of deep-water underwater multi-functional manifold systems, which were independently designed, built, and tested by the country, was delivered at the Tianjin Lingang Special Equipment Manufacturing Facility of CNOOC Offshore Engineering Co., Ltd. (hereinafter referred to as \"CNOOC Offshore Engineering\"). This marks a significant breakthrough in China’s capabilities in the independent research, development, design, manufacturing, and testing of underwater oil and gas production equipment; the overall design technology as well as the key components involved have broken foreign monopolies.
It is understood that the multi-functional manifold delivered this time will be used in the development of the Dongfang Gas Field complex, which is under the jurisdiction of CNOOC Hainan Branch. It integrates 11 domestically produced key control and monitoring devices, including underwater distribution units, control modules, and routers; it represents the first engineered underwater manifold with a control system designed and developed in China for depths of 500 meters.
