Zusammenfassung:PURPOSE: A method for operating an oil-hydraulic circuit of a submarine is provided to prevent the inflow of seawater into an oil-hydraulic circuit by regularly keeping working pressure higher than submerge pressure. CONSTITUTION: A method for operating an oil-hydraulic circuit of a submarine is as follows. One or more device(54) of the oil-hydraulic circuit is arranged in the outside of a pressure-resistant hull(15). The working pressure of the device, which is located in the outside of the pressure-resistant hull, is regularly maintained over the submerge pressure. The device of the oil-hydraulic circuit is established. The working pressure of the device, which is located in the pressure-resistant hull, is regularly maintained lower than the working pressure of the device which is located in the outside of the pressure-resistant hull.
