To provide a handling method for a liquefied cryogenic fluid capable of proper handling, even when BOG is generated from the liquefied cryogenic fluid being heated by a relatively high temperature of a fluid conduction pipe or a pressure feed pump in an early stage in the handling.SOLUTION: When pre-cooling the fluid conduction pipe by flowing a portion of the liquefied cryogenic fluid thereinto, prior to handling the liquefied cryogenic fluid, a partial inflow pre-cooling operation is executed for carrying out pre-cooling in a state where a non-inflow space RK is formed in which the liquefied cryogenic fluid does not exist in at least one part inside the fluid conduction pipe for conducting the liquefied cryogenic fluid.SELECTED DRAWING: Figure 15
【課題】荷役の初期において、比較的高温の流体通流管や圧送ポンプにより液化低温流体が加熱されBOGが発生する場合であっても、良好に荷役を実行できる液化低温流体の荷役方法を提供する。【解決手段】液化低温流体の荷役に先立って流体通流管に液化低温流体の一部を流入して予冷する際に、液化低温流体を通流する流体通流管の内部の少なくとも一部に液化低温流体が存在しない非流入空間RKを形成する状態で予冷する部分流入予冷運転を実行する。【選択図】図15
