To provide a cryogenic liquid pipe structure that can restrain a structural material of a ship from being made brittle by an effect of drops of liquefied air formed on a surface of a pipe through which cryogenic liquid flows, in association with a decrease in temperature of the pipe, and the ship comprising the same.SOLUTION: A cryogenic liquid pipe structure is applied to a ship for storing cryogenic liquid with a boiling point of -196°C or less at normal pressures. The pipe structure comprises: a low-temperature pipe (10) routed along a structural material (4) of a ship (1) at a position separated upward from the structural material (4), and through which cryogenic liquid flows; and a storage region partition member (20) arranged on the structural material (4), and for partitioning a storage region (AR) capable of storing evaporation promoting liquid for receiving and evaporating drops of liquefied air when the liquefied air is formed on a surface of the low-temperature pipe (10), on the structural material (4).SELECTED DRAWING: Figure 4

    【課題】極低温液体が流通する配管の温度低下に伴って当該配管の表面に形成された液化空気の滴下の影響で船舶の構造材が脆化するのを抑制し得る極低温液体用配管構造、及びそれを備えた船舶を提供する。【解決手段】極低温液体用配管構造は、常圧での沸点が-196℃以下の極低温液体を貯留する船舶に適用される。この配管構造は、船舶(1)の構造材(4)から上方に離れた位置で当該構造材(4)に沿って配索され、極低温液体が流通する低温配管(10)と、構造材(4)上に配置され、低温配管(10)の表面に液化空気が形成された場合に当該液化空気の滴下を受け止めて蒸発させる蒸発促進液体の貯留が可能な貯留領域(AR)を、構造材(4)上に区画する貯留領域区画部材(20)と、を備える。【選択図】図4
