| 1. Device for supplying fuel to an onboard energy production installation (5) on a liquefied gas transport ship (1) from at least one liquefied gas tank (2) of the said ship, characterized by the fact that the said device comprises:
a liquid ejector (12, 112) arranged in the said tank in order to suck liquefied gas at the level of the bottom of the said tank,
a circulating pump (20, 120, 201) arranged above the said tank,
a liquid circuit (21, 22, 23, 24; 121, 122) connecting an outlet of the said circulating pump to an inlet of the said liquid ejector and an outlet of the said liquid
ejector to an inlet of the said circulating pump to permit the closed-loop circulation of a stream of liquefied gas through
the said liquid ejector,
a feed line (28, 128) connecting the said liquid circuit to the said energy production installation,
wherein the said auxiliary tank is a buffer tank (23) inserted in the said liquid circuit (21-24) between the said outlet of the liquid ejector (12) and the said inlet of the circulating pump (20, 201), and
a return line (32) connecting the said feed line (28) to the said buffer tank (23), the said return line being equipped with a control valve (33) actuated according to the pressure in the said feed line.
