PROBLEM TO BE SOLVED: To provide a liquefaction hydrogen transfer system capable of inputting heat to a joint for low temperature fluid or its surroundings when the joint for low temperature fluid is cut.SOLUTION: A liquefaction hydrogen transfer system 1 for transferring liquefaction hydrogen between a land side first tank 2 and the second tank 3 at a liquefaction hydrogen transport ship includes a liquefaction hydrogen transfer system 4 of which almost segments are constituted by a vacuum thermal insulation duplex tube; a low temperature fluid joint 4b installed at the liquefaction hydrogen transfer system 4; a heat inputting means 7 capable of inputting heat into the inner pipe of the vacuum thermal insulation duplex tube in at least prescribed length segments of both sides of the low temperature fluid joint 4b of the liquefaction hydrogen transfer system 4. The heat inputting means 7 comprises helical tubes 7a, 7b wound around the outer peripheral surface of the inner tube, electrical heaters assembled into the helical tubes 7a, 7b, thermal medium filled in the helical tubes 7a, 7b, and the first and second electric conduction means 7c, 7d for electrically conducting the helical tubes 7a, 7b.SELECTED DRAWING: Figure 1
