【Ten Years of Rapid Development in Chemical Processing Equipment】Domestically produced shallow-water underwater direction control valves passed DNV certification between 2018 and 2023
Thread Content
Ten years of rapid development in chemical engineering equipment – praising the prosperity and strength of modern China. This is just a starting point; more participation from everyone will make things even more lively. Haichuan becomes even better with your involvement; we welcome everyone to take an active part in the forum discussions. ********************************************* The “shallow-water subsea directional control valve” for the Bohai Oil and Gas Field has passed DNV certification and inspection. Recently, the engineered version of this valve, developed as part of the research and demonstration project on domestic production control systems for subsea operations in oil and gas fields, was approved at the Beijing Research Center of CNOOC (China) Co., Ltd., by the Deep-Sea Oil and Gas Subsea Intelligent Control Laboratory at China University of Petroleum (Beijing). Relevant leaders from CNOOC General Hospital, along with representatives from authoritative third-party organizations such as DNV, participated in and witnessed the final product inspection and acceptance through a combination of offline and online methods. All tests on the product were successfully passed, and the experts present agreed that the product quality and performance parameters of the shallow-water underwater direction control valves produced by China University of Petroleum (Beijing) have reached world-class standards!
The underwater directional control valve delivered this time has been upgraded in terms of material compatibility, structure, sealing, integration, and testing techniques; it features excellent sealing properties and can be used in high-temperature and high-pressure underwater environments. Equipped with a pressure transmitter, it ensures stable and reliable operation underwater for extended periods of time. The underwater directional control valve is the most critical component in underwater production systems. Until now, the key technologies related to this product have been monopolized by foreign companies; such valves had to be imported entirely. The DCVs produced by FMC, Aker, and Cameron are developed by their own internal teams or supplied by third-party companies, and they are not sold to China. The price of DCVs sold by British Bifold to China is quite expensive. The project on the research and demonstration of the localization of underwater production control systems for the Bohai Sea oil and gas fields, specifically the development of \"engineering-grade shallow-water directional control valves (DCVs)\\", aims to break the foreign monopoly on the design technology for such valves. It seeks to establish manufacturing techniques for directional control valves that involve independent intellectual property rights, thereby overcoming foreign technological constraints and ending reliance on others. The outcomes of this project will provide CNOOC with a stable supply of products and technical support for exploring deep-water oil and gas resources, helping to save substantial costs for China’s offshore oil and gas industry and significantly improving its economic efficiency.
The engineering application of the underwater directional control valve (DCV) from the Deep-Sea Oil and Gas Underwater Intelligent Control Laboratory at China University of Petroleum (Beijing) in the Jinzhou 25-1 gas field represents the first domestically developed underwater directional control valve during the 14th Five-Year Plan period. It is also the first such valve to receive certification from DNV in China, and it constitutes the first practical application in the development of underwater oil and gas fields in Chinese waters. This marks another significant step forward in the industrialization of deep-water oil and gas exploration technologies owned by China!
