Abstract: Studies have been conducted to master the shallow-water test technology of subsea hydraulic control system based on the multiplexed electrohydraulic control system. The test systems and their connection needed for shallow-water test sites were proposed after the compositions， operating principle and functional requirements of the system were analyzed and the existing standards and the testing state at home and abroad were studied. Testing items were determined， testing procedures established and testing methods elaborated. The testing results can be used as a reference for the construction of shallow-water test sites and shallow-water test operation at home.
