METHOD FOR FILLING A TANK WITH LIQUEFIED GAS

Method for filling a tank (2) with pressurized liquefied gas from a source (4) of liquefied gas, using a filling apparatus 5 comprising a transfer circuit provided with a first pipe (3) for liquid transfer comprising a first end (13) connected to the source (4) of liquefied gas and a second end (23) connected to the liquefied gas tank (2), a second pipe (6) for gas transfer comprising a first end (16) connected to a gas recovery member 0 (8) and a second end (26) connected to said tank (2) to be filled, the circuit comprising a third transfer pipe (5) and a fourth transfer pipe (7), each connecting the first (3) and second (6) transfer pipes, the circuit comprising a set of valves (36, 46, 13, 33, 15, 17) for controlling the flows of fluid in 5 the pipes of the circuit, the method comprising, prior to the transfer of liquefied gas from the source (4) of liquefied gas to the liquefied gas tank (2), a depressurization of the liquefied gas tank (2) and a cooling of at least part of the transfer circuit, wherein the depressurization of the liquefied 0 gas tank (2) and the cooling of the transfer circuit comprises a transfer of pressurized vaporization gas contained in the liquefied gas tank (2) via the second end (26) of the second pipe (6) for gas transfer, the third transfer pipe (5), the first transfer pipe (3), the fourth transfer pipe (7) and the first 5 end (16) of the second transfer pipe (6).
