A liquefied hydrogen transport system (1) for transporting liquefied hydrogen between a land-side first tank (2) capable of storing liquefied hydrogen and a second tank (3) on the liquefied hydrogen transport ship side and also capable of storing liquefied hydrogen is equipped with: a liquefied hydrogen transport line (4) principally configured from a vacuum-insulated double-walled pipe (30) and capable of transporting liquefied hydrogen between the first tank (2) and the second tank (3) through a loading arm (4a); a low-temperature fluid joint (4b) installed in the liquefied hydrogen transport line (4); and a heat input means (7) capable of inputting heat into an inner pipe (31) of the vacuum-insulated double-walled pipe (30) in at least a section of the liquefied hydrogen transport line (4) comprising a prescribed length toward the land side from the low-temperature fluid joint (4b) therein and a section thereof comprising a prescribed length toward the ship side from the low-temperature fluid joint (4b) therein. Furthermore, the heat input means (7) has helical tubes (7a, 7b) wrapped around the outer-circumferential surface of the inner pipe (31), an electrical heater (31a) incorporated into the helical tubes (7a, 7b), a heat medium sealed inside the helical tubes (7a, 7b), and first and second conduction means (7c, 7d) for conducting power to the helical tubes (7a, 7b). |
