Thumbs up for the achievements of China's chemical technology and equipment. * * * * * * * * * * * * * * * * * * * * * * [Ten years of development of chemical equipment] Continue to update summary posts, welcome to participate in the discussion https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Forum Network) * * * * * * * * * * * * * * * * * The first claw-type underwater connector in China, jointly developed by Offshore Oil Engineering Co., Ltd. and our school, successfully completed its first sea trial at Shenzhen Chiwan Deepwater Terminal on March 29, 2012, marking that Offshore Oil Engineering Company has made phased progress in the development of deep-water underwater products. It will also ensure that my country accelerates the pace of deep-water oil exploration and development in the South China Sea. * * Energy security will play an important role. Underwater connectors are one of the indispensable core devices for setting up underwater production systems. They have broad application prospects, high technical difficulties, and high added value. The market has been monopolized by a few foreign manufacturers for many years. Purchasing imported underwater connectors is not only expensive and has a long supply cycle, but also relies on foreign installation machinery and personnel, which is very detrimental to the development of domestically owned technology and the development of deepwater oil and gas fields in the South my country Sea. At present, my country's offshore oil industry is at a critical stage of leaping from shallow water to deep water. In order to seize opportunities and meet challenges, Offshore Oil Engineering Company has established deepwater engineering capacity building and underwater oilfield facility maintenance capacity building as the main direction of the company's future development strategy. Underwater connectors are one of the key underwater products to be developed. As early as 2007, the company carried out preliminary research and conceptual design for claw-type underwater connectors. In 2009, a company-level project undertaken by Offshore Oil Engineering Company conducted in-depth research on claw-type underwater connectors. The topic was led by Chief Engineer Li Zhigang of COOEC, and was attended by Deputy General Manager Zhou Meizhen of COOEC and Professor Wang Liquan, Senior Engineer Liu Jun and Associate Professor Gong Haixia of our school. Offshore Oil Engineering Design Company and our school gave full play to the advantages of combining industry, academia and research. After nearly three years of research, they solved technical problems such as the structural design of the connector, the fixing method of the sealing ring, and the processing technology of the claws, and finally developed the first claw-type underwater connector prototype in China. During product design, manufacturing and sea trials, General Manager Zhou Hongbo of the Science and Technology Development Department of China National Offshore Oil Corporation provided on-site guidance many times. Chief Engineer Li Zhigang of Offshore Oil Engineering Co., Ltd. personally conducted on-site operations and worked on-site to coordinate and resolve existing problems. ROV operators, diving operators and other personnel worked closely with the research team to overcome the influence of a series of unfavorable factors such as turbid seawater and low visibility, and successfully completed a series of functional and performance tests such as lowering the connector installation tool, underwater docking, locking and sealing pressure testing. Zhou Hongbo said: “The first sea trial of the claw-type underwater connector was successful, filling a domestic gap and laying a solid foundation for realizing the industrialization of the product and advancing the development and construction of deepwater oil and gas fields. ”
