Method for filling a tank with liquefied gas

A method for filling a liquefied gas tank with pressurized liquefied gas from a source of liquefied gas, using a filling apparatus comprising a transfer circuit that is provided with a first pipe for liquid transfer, a second pipe for gas transfer, a third pipe, a fourth pipe, and a set of valves for controlling flows of fluid in said pipes, the first pipe comprising a first end connected to the source of liquefied gas and a second end connected to the liquefied gas tank, the second pipe comprising a first end connected to a gas recovery member and a second end connected to said liquefied gas tank, each of the third and fourth pipes connecting the first and second pipes, said method comprising the step of, prior to the transfer of liquefied gas from the source of liquefied gas to the liquefied gas tank, depressurizing the liquefied gas tank and cooling at least part of the transfer circuit, wherein:

• said step of depressurizing and cooling comprises transferring pressurized vaporization gas contained in the liquefied gas tank via the second end of the second pipe, the third pipe, the first pipe, the fourth pipe, and the first end of the second pipe.
