Abstract:
A liquefied hydrogen transport method includes connecting first and second loading arms to the manifold while vacuum insulation double tubes of the first and second loading arms are filled with hydrogen gas and air is mixed in piggyback lines; supplying an inactive gas to one of the piggyback lines of the first and second loading arms and taking in a gas mixture of an inactive gas and air from the other of the piggyback lines of the first and second loading arms; supplying hydrogen gas to one of the piggyback lines of the first and second loading arms and taking in a gas mixture of hydrogen gas and an inactive gas from the other of the piggyback lines of the first and second lading arms; and transporting liquefied hydrogen through any one of the vacuum insulation double tubes of the first and second loading arms.

Claim (Index 1):
A liquefied hydrogen loading arm configured to transport liquefied hydrogen, the loading arm comprising:\n a loading arm support frame structure including a base riser erected on a ground, an inboard boom, an outboard boom, and a counterweight attached to a proximal end portion of the inboard boom; a flexible vacuum insulation double tube including a metal inner tube, a metal outer tube, and an insulation vacuum layer, disposed in a space below the support frame structure, and supported by the support frame structure; a vacuum insulation double connecting tube connected to a distal end portion of the vacuum insulation double tube and connected to a distal end portion of the outboard boom; an arm-side opening/closing valve and an emergency release system sequentially interposed in the vacuum insulation double connecting tube from a vacuum insulation double tube side; and a flexible piggyback line disposed along the vacuum insulation double tube, having a proximal end portion configured to be selectively connected to an inactive gas tubing and a hydrogen gas tubing on a land through a land-side opening/closing valve, and having a distal end portion connected to the vacuum insulation double connecting tube between the arm-side opening/closing valve and the emergency release system.
