Abstract

The fluid swivel is an important component in the FPSO single point mooring system that performs the functions of rotation, sealing and fluid transmission. To verify the safety and reliability of the function and structure of the fluid swivel in the long-term marine environment, this paper conducts research on the comprehensive performance test method of the fluid swivel. According to the performance index requirements of the newly added 8-inch domestic fluid swivel products of the Nanhai-Fenjin FPSO, the test device for simulating the dynamic marine environment was designed, and 2 running-in tests and 4 functional pressure tests were formulated. Through the above tests, the sealing pressure, rotational torque and fluid transmission performance of the fluid swivel were tested under static and dynamic swing conditions. The test results show that the comprehensive performance of the domestic fluid swivel meets the design requirements, which provides ideas and guidance for future performance testing and verification of the domestic fluid swivel.
