Recently, the "South China Sea Endeavour" FPSO developed by HYGC Ocean Engineering Corporation
The liquid slip ring of the floating production storage and unloading device has passed the acceptance inspection smoothly.
This is an FPSO single point system liquid slip ring independently designed and constructed by China, which is of great significance for improving China's equipment manufacturing level and ensuring national energy security.
South China Sea Endeavour FPSO Single Point Mooring System
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 transport high-pressure hazardous media under the rotating state of FPSO load. Among them, the control of rotational clearance is a key technology for the stable operation of the liquid slip ring.
In order to crack this "core technology password", HYGC has established a joint research and development team with Chinese universities to implement key core technology research. It has taken the lead in initiating demonstration research on the liquid slip ring project in China, starting from the design of the liquid slip ring, conducting multiple technical discussions and reviews, optimizing design, manufacturing, and testing plans, and tackling rotating clearance control, quasi-static sealing design, bearing selection
Technical difficulties such as high-precision machining of slip ring body
To fully verify the performance of the liquid slip ring
The project team adopted testing standards higher than international standards and developed a simulated "shaking+rotation" test bench, completing airtightness, water pressure, pressurized rotation, and shaking tests, with no leakage throughout the entire process;
The product has passed BV (Bureau Veritas) certification.
