To verify the safety and reliability of the function and structure of the fluid swivel in the long-term marine envi-ronment,this paper conducted research on the comprehensive performance test method of the fluid swivel.According to the performance index requirements of the newly added 8-inch do-mestic 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,and the sealing pressure,rotational torque and fluid transmission performance of the fluid swivel were tested under static and dynamic swing conditions respec-tively.Results show that the comprehensive performance of the domestic fluid swivel can meet the design requirements,which provides a reference for future performance testing and verifi-cation of the domestic fluid swivel.
