PROBLEM TO BE SOLVED: To provide a marine vessel equipped with a pipeline for dumping liquid hydrogen on the sea capable of restricting the blockage of the tip of the pipe outer peripheral portion caused by solid air at the time of dumping on the sea.SOLUTION: In a liquid hydrogen transport ship 1 having a pipeline 7 for dumping liquid hydrogen on the sea which is a load stored in a spherical tank 2, the pipeline 7 includes: an inner pipe 7a through which liquid hydrogen flows; an outer pipe 7b which includes a part with a larger surface area than other parts on its tip side and which forms a vacuum layer 7f in a radial direction gap with the inner pipe 7a; and a plurality of fins 9 which are arranged substantially parallel to the axis at least at the tip side portion of the outer pipe 7b and extend radially.SELECTED DRAWING: Figure 5

    【課題】海上投棄時、配管外周部の先端が固体空気により閉塞されることを抑制することができる液体水素を海上に投棄する配管を備えた船舶を提供する。【解決手段】球形タンク2に貯留された積荷である液体水素を海上に投棄するための配管7を備えた液体水素輸送船1において、配管7は、液体水素が内部を流れる内管7aと、他部よりも表面積が大きな部分をその先端側に含み且つ内管7aとの径方向隙間に真空層7fを形成するための外管7bと、この外管7bの少なくとも先端側部分に軸心と略平行に配設され且つ放射状に延びる複数のフィン9とを有している。【選択図】図5
