A self-contained liquefied gas supply system has a tank for storing a liquefied gas, a primary pump for delivering the liquefied gas from the tank, a secondary pump for pressurizing the liquefied gas delivered from the primary pump, a vaporizer for vaporizing the liquefied gas discharged from the secondary pump into a vaporized gas, an expander for actuating the secondary pump with the vaporized gas produced by the vaporizer, and a back-pressure line connected to an outlet of the expander. A bypass pipe is connected between the primary pump and the vaporizer in bypassing relation to the secondary pump for supplying the liquefied gas from the primary pump to the vaporizer. A joint line is connected between the back-pressure line and a substantially atmospheric pressure line, the joint line having a first flow regulating valve for regulating a rate of flow of a gas from the back-pressure line to the substantially atmospheric pressure line. A bypass line is connected between the vaporizer and the back-pressure line in bypassing relation to the expander, the bypass line having a second flow regulating mechanism for regulating a rate of flow of the vaporized gas from the vaporizer to the back-pressure line. For starting the secondary pump, the liquefied gas is delivered from the primary pump through the bypass pipe to the vaporizer, which produces a vaporized gas supplied to the expander.
