Abstract
The present invention relates to a method and a system for supplying liquefied gas source tank (110) to a liquefied gas consumer tank (200) and/or liquefied gas consumer, wherein the liquefied gas is supplied via a transfer line (130, 140, 210) to the liquefied gas consumer tank (200) and/or the liquefied gas consumer, and wherein after having supplied liquefied gas to the liquefied gas consumer tank (200) and/or liquefied gas consumer, residual liquefied gas remaining in at least a part of the transfer line (130, 140, 210) is drained into a liquefied gas holding tank (120) and a pressurized gas is then fed into the liquefied gas holding tank (120) in order to return at least a part of the residual liquefied gas in the holding tank via a return line (160) back into the liquefied gas source tank (110).
