PROBLEM TO BE SOLVED: To provide a liquefaction hydrogen transfer system capable of preventing the creation of solid nitrogen inside an on-off valve while precooling being possible up to the vicinity of the tip of a loading arm including the loading arm.SOLUTION: A liquefaction hydrogen transfer system comprises: a liquefaction hydrogen transfer circuit (4A) that can transfer liquefaction hydrogen between first and second tanks using a loading arm (14); first and second on-off valves (15a and 15b) separately arranged between an out board arm (14b) of the loading arm and a blank flange, from the blank flange side in order in a land side transfer circuit (4A) from the first tank to a blank flange (16) on the tip side of the loading arm in a liquefaction hydrogen transfer circuit (4); nitrogen gas filling means (10) provided along a first passage part (4a) between the blank flange and the first on-off valve; hydrogen gas filling means (8) provided along a second passage part (4b) between the first and second on-off valves; and liquefaction hydrogen filling means (12) provided along a third passage part (4c) between the second on-off valve (15b) and the first tank for precooling the land side transfer circuit.SELECTED DRAWING: Figure 1

    【課題】ローディングアームを含めてその先端付近まで予冷可能で、開閉弁の内部での固体窒素の生成を防止可能にした液化水素移送システムを提供する。【解決手段】第1タンクと第2タンクとの間でローディングアーム(14)を介して液化水素を移送可能な液化水素移送系統(4A)と、液化水素移送系統(4)のうちの第1タンクからローディングアームの先端側の盲フランジ(16)までの陸側移送系統(4A)においてローディングアームのアウトボードアーム(14b)と盲フランジ間に盲フランジ側から順に離隔状に配設された第1,第2開閉弁(15a,15b)と、盲フランジと第1開閉弁間の第1通路部(4a)に窒素ガス充填手段(10)と、第1,第2開閉弁の間の第2通路部(4b)に水素ガス充填手段(8)と、陸側移送系統の予冷の為に、第2開閉弁(15b)と第1タンク間の第3通路部(4c)に液化水素充填手段(12)とを備えている。【選択図】図1
