Abstract:  Subsea hydraulic actuator is the power unit in the hydraulic oil and gas production, which is controlled by the subsea hydraulic system. The subsea actuators and valves are influenced by the subsea hydraulic system. We introduce the hydraulic system and the subsea control module (SCM) hydraulic systems, model the return pressure in the high pressure return line, and use the SimulationX software to perform dynamic simulation. Analysis and comparative study on the simulation results verify the control system, as well as the feasibility of the simulation. This research can provide reference for the investigation of deepwater hydraulic control systems.
