An apparatus for transferring a cryogenic fluid. The apparatus includes a conduit having an inlet and an outlet, a source of cryogenic fluid connected to the inlet for providing cryogenic fluid to the conduit and a cool down line connected to the conduit at an intermediate port between the inlet and the outlet, the cool down line in fluid communication with the source of cryogenic fluid for providing cryogenic fluid to the conduit through the intermediate port. The cool down line can be external and intersect with the conduit at the intermediate port, or may be disposed within the conduit. The conduit may have more than one intermediate port for providing cryogenic fluid to the conduit downstream from the inlet. Such an apparatus enables a conduit for transferring a cryogenic fluid to be pre-cooled to a cryogenic temperature more quickly so that transfer operations can begin.
