Abstract: A fluid loading joint for rotatably connecting double pipes to each other includes: a first half including a first inner pipe, a first outer pipe, and a holder, the first inner pipe being provided with a first flange, the first outer pipe accommodating the first inner pipe therein, the holder holding the first outer pipe such that the first outer pipe is rotatable; a second half including a sliding surface facing the first flange, the second half including a second inner pipe and a second outer pipe, the second inner pipe being provided with a second flange, the second outer pipe accommodating the second inner pipe therein and being provided with an outer flange that is fastened to the holder; an inner sealing member and an outer sealing member that are disposed between the first flange and the sliding surface; an inner passage provided in the second flange, the inner passage leading a leaked fluid from between the inner sealing member and the outer sealing member to an outer circumferential surface of the se

Abstract: A fluid loading joint includes: a first half provided at an end of a first vacuum double pipe, the first half including a first inner pipe, a first outer pipe, and a first blocking member blocking between the first inner pipe and the first outer pipe; a second half provided at an end of a second vacuum double pipe, the second half including a second inner pipe, a second outer pipe, and a second blocking member blocking between the second inner pipe and the second outer pipe; an annular inner insulator interposed between the first inner pipe and the second inner pipe; and an annular outer insulator interposed between the first outer pipe and the second outer pipe, the outer insulator surrounding the inner insulator, with a gas space positioned between the outer insulator and the inner insulator, the gas space being formed between the first blocking member and the second blocking member.

Abstract: An emergency release system includes a first shut-off valve unit which is land-based; and a second shut-off valve unit which is provided for a marine vessel and separably connected to the first shut-off valve unit, and the first shut-off valve unit is provided with a reservoir container which receives liquid air generated in the first shut-off valve unit and dropped, in a state in which the second shut-off valve unit is separated from the first shut-off valve unit, and the system includes a container support mechanism which is capable of retaining the reservoir container at a retracted position in a state in which the first and second shut-off valve units are connected to each other, the container support mechanism being configured to automatically shift the reservoir container to a reserving position, in a state in which the first and second shut-off valve units are separated from each other.

Abstract: An object is to propose a fluid handling device for liquid hydrogen that prevents evaporation of liquid hydrogen, and moreover affords excellent heat insulation without liquefying oxygen in the vicinity.

Abstract: To provide an emergency detachment mechanism for a fluid handling device that has exceptional heat insulation performance and enables liquid hydrogen or another very-low-temperature fluid to be handled. An emergency detachment mechanism for a fluid handling device provided with a pair of couplers 1, wherein each of the pair of couplers 1 has a coupler body part 5 including an internal tube part 2 in which a fluid passes through an interior and which opens at a distal end side, an external tube part 3 which forms a vacuum layer 9 with the internal tube part 2 and which opens at a distal end side, and a connecting flange part 4 that closes off a space between the internal tube part 2 and the external tube part 3, a wall thickness of the connecting flange part 4 being less than a wall thickness of the external tube part 3.

Abstract: A liquefied hydrogen loading arm configured to transport liquefied hydrogen includes: a support frame structure including a base riser erected on a ground, an inboard boom, an outboard boom, and a counterweight; a flexible vacuum insulation double tube including a flexible metal inner tube, a flexible metal outer tube fitted on the inner tube, and a vacuum layer, the vacuum insulation double tube being disposed in an upward curved shape in a space below 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; and a midway portion support mechanism configured to support a lengthwise midway portion of the vacuum insulation double tube on the support frame structure through a hard curved member curved upward in a convex shape.

Abstract: An object is to provide an emergency detachment device of a fluid handling device, the emergency detachment device having exceptional heat insulation performance and making it possible to handle extremely-low-temperature fluids such as liquid hydrogen. A first coupler 2 and a second coupler 3 are provided with a vacuum section 10 between an inner pipe section 5 and an outer pipe section 6, and are provided with two valves 1 in series. A remaining-fluid-transferring mechanism is provided such that, after second valves 1B provided further inward enter a closed-valve state during emergency detachment, residual fluid that remains closer to the first valves 1A than the second valves 1B is transferred into the inner pipes sections 5 provided further inward of the second valves 1B.
