[Chemical Equipment Powerful Country and Important Equipment] 433-2022 my country’s first 500-meter water depth zone control system underwater manifold engineered product was delivered for use in Tianjin
Thread Content
On June 6, the COOEC Tianjin Lingang Special Equipment Manufacturing Site held a delivery event for my country’s first deepwater underwater multi-functional manifold system. The Ministry of Industry and Information Technology’s underwater oil and gas production system engineering demonstration innovation project was* * The key projects of the Ministry of Industry and Information Technology are implemented by the group company * * * * It is one of the most important projects in the seven-year action plan to “increase domestic oil and gas exploration and development”. As a professional engineering services company of the group company, COOEC is very fortunate to participate in the R&D, design, manufacturing and testing of this innovative special underwater multi-functional manifold. Since the construction of the project started, COOEC has coordinated the design, manufacturing and assembly, factory testing, third-party certification and system integration testing, and has been working hard with various collaborating units for 10 consecutive months. Overcoming the impact of the COVID-19 epidemic, it has completed manufacturing integration, factory testing, control system system testing, equipment installation, recovery and operation testing, etc. It has overcome multiple technical difficulties and completed the construction of the underwater multi-functional manifold safely and smoothly.
It is understood that the multi-functional manifold delivered this time will be used in the development of the Dongfang Gas Field Group owned by CNOOC Hainan Branch. It integrates 11 domestically produced key control and monitoring equipment such as underwater distribution units, control modules, routers, etc. It is the first domestically independently developed underwater manifold engineered product with a control system for a water depth of 500 meters. The delivery of the deepwater underwater multi-functional manifold system marks an important breakthrough in my country's independent research and development, design, manufacturing and testing technology of offshore oil and gas underwater production equipment.
Important functions: Subsea manifolds are mainly distributed among the wellhead groups on the seabed. They have a series of important functions such as collecting wellhead oil and gas, distributing electric power and hydraulic pressure, and conducting underwater control and monitoring. They are known as underwater "oil and gas hubs" and are one of the core technical equipment for the development of deepwater oil and gas fields. They play an important role in gathering deep-sea oil and gas and transporting them to the "processing center" - the offshore platform. It is understood that due to its late start, the underwater multi-functional manifold used in my country's deepwater oil and gas field development projects has previously been designed by foreign manufacturers, and its overall design technology and key components have long been monopolized by a few foreign companies.
The underwater multi-functional manifold delivered this time faces harsh environmental conditions such as high pressure, low temperature and seawater corrosion, and requires 20 years of maintenance-free operation. Therefore, it poses great challenges to equipment sealing, material strength and process quality. It is reported that since 2019, COOEC has relied on the Ministry of Industry and Information Technology's "Engineering Demonstration Application of Underwater Oil and Gas Production System" innovative special implementation to vigorously carry out key technology research and overcome control system integration, three-dimensional design of complex underwater structures, control and monitoring equipment ROV (underwater robot) ) operation design, interface matching design and a series of technical problems, and integrated domestic superior scientific research resources, successfully achieved independent research and development and localized manufacturing of various key components such as underwater hydraulic valves, connectors, multi-phase flowmeters, etc., and completed product type testing and certification in accordance with the requirements of advanced international industry standards.
