Chemical science and technology has developed greatly in the past ten years, praising the prosperity of China in the prosperous world. The ocean is more lively and exciting with everyone's participation. Everyone is welcome to participate in the forum to exchange and discuss the fire in July, pay attention to fire prevention-------------------------------------------------Single-point mooring system is one of the key equipment in the field of marine engineering. As its core component, the liquid slip ring is mainly used to realize the transportation of high-pressure dangerous media in the FPSO rotating state under load. Among them, the control of the rotation gap is the key technology for the stable operation of the liquid slip ring. In May 2023, the liquid slip ring of the "Nanhai Endeavor" FPSO (Floating Production, Storage and Offloading Unit) constructed by COOEC successfully passed the acceptance inspection. This is my country’s first independently designed and constructed FPSO single-point system liquid slip ring, which is important for improving my country’s equipment manufacturing level and ensuring * * Energy security is of great significance. “The independent design and construction of the liquid slip ring for the Nanhai Endeavor FPSO single-point mooring system is a key task for CNOOC to promote technological innovation and solve key core technology major projects. The implementation of the project will effectively make up for my country's shortcomings in the design, manufacturing, installation, commissioning and operation and maintenance services of single-point mooring systems, and enhance the overall strength of my country's single-point technology.
In order to crack this "core code", COOEC cooperated with domestic universities to implement key core technology research, and took the lead in launching liquid slip ring engineering demonstration research in China. Starting from the design of the liquid slip ring, we carried out multiple technical discussions and reviews, optimized the design, manufacturing, and testing plans, and overcame technical problems such as rotational gap control, quasi-static seal design, bearing selection, and high-precision machining of the slip ring body. The construction was completed four months earlier than similar foreign products.
