    摘要: The present invention relates to a method for regulating a pressure in a hydraulic system for operating at least one actuator in a subsea installation, having a fluid supply line (102) connected to a source of pressurized fluid (101) at a remote location delivering fluid at a constant pressure to the subsea installation, comprising first and second control valves (103, 105) controlled by an electronic control unit (107), and at least one pressure sensor (106) and an accumulator (104) arranged between the first and second control valve (103, 105), where the pressure in the fluid supply line (102′) to the actuator is regulated by regulating the pressure in the accumulator (104) by adding fluid from the source of pressurized fluid (101) through the first control valve (103) if the pressure is too low or releasing pressure through the second control valve (105) to a fluid return line (120) if the pressure is too high and thereby establishing the desired pressure for operating the actuator. The invention also relates to a device for performing the method.
