Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】A continuously updated summary post is available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Recently, China National Offshore Oil Corporation successfully put into use the country’s first drilling riser system designed for depths of 1,500 meters, developed through independent research. The riser system put into use this time consists of 30 sets of equipment, with independent control achieved in the aspects of research and development, manufacturing, and operation and maintenance. 　　This system is a key component that connects offshore floating drilling platforms to subsea wellheads; it can handle loads of 8,896 kN at the joints, with the side pipes capable of withstanding pressures of 103.5 MPa, thereby ensuring the safety of drilling operations at depths of up to 1,500 meters. During the independent development process, the R&D team overcame challenges such as the multidimensional heavy-load design of riser joints and efficient connection sealing technologies. In addition, the project has developed a full-life-cycle management system for risers, which not only features functions such as operation window analysis but also enables digital monitoring and maintenance of the entire life cycle of individual risers through chip technology.
