The present invention relates to a natural gas hydrate tank container loading system for transporting natural gas hydrate, and the present invention provides a natural gas hydrate tank container loading system which enables automated connection of an electric power line and a boil-off pipe, and may automatically connect an electric power line and automatically connect the pipe by simultaneously stacking respective natural gas hydrate tank containers, in order to solve problems of a transportation method using the existing natural gas hydrate tank containers in the related art in that an operation of connecting an electric power line to a refrigerator for minimizing the occurrence of boil-off gas and maintaining a phase equilibrium condition in the tank containers and an operation of connecting the pipe for discharging the boil-off gas need to be manually and individually performed for long-distance transportation of a large amount of natural gas hydrate by using a ship, which causes an inconvenience.

A gas cylinder mobility aid is provided. A gas cylinder mobility aid for attachment to a collar of a gas cylinder, comprising a base plate having an upper surface and a lower surface. One or more coupling members affixed to the lower surface of the base plate wherein the one or more coupling members are positioned to form a frictional fit with the collar of the gas cylinder. A vertical member affixed at the center of said base plate and a handle rotatably attached to the vertical member such that the handle is present above the upper surface of the base plate and the handle rotates about the vertical member.

A handle assembly for a portable gas cylinder includes a first handle portion, a second handle portion and first and second locking members. The first handle portion includes an ergonomically configured upstanding gripping handle and a semi-circular shroud portion configured to couple to a first section of an upper portion of a portable gas cylinder. The second handle portion includes an ergonomically configured upstanding gripping handle and a semi-circular shroud portion configured to couple to a second section of the upper portion of the portable gas cylinder. First and second locking members are configured to selectively locking the first and second handle portions to one another about a periphery of the upper portion of the portable gas cylinder.

An assembly for storing and transporting compressed fluid, such as compressed natural gas, that includes a plurality of hexagonally stacked pipe stored in a cargo hold in or on a vessel, that includes a lower support, side supports and a forcing mechanism that presses strongly down on the pipes so that they cannot move relative to themselves or the vessel on which they are placed. The friction between the pipes causes the plurality of pipes to act as part of the vessel in terms of its structure. The stacked pipe is supported by a plurality of spacers, such as convex side up pipe segments for maintaining a gap between adjacent ones of said plurality of pipes in a same row in said stacked pipe. A load equalizer may be located above the plurality of pipes for distributing the compressive force from the forcing mechanism.

The present disclosure relates to an apparatus for fixing a pressure vessel, the apparatus including: a frame part disposed separably from a subject and configured to support a pressure vessel; and a lifting device configured to selectively raise or lower the frame part relative to the subject, thereby facilitating a process of replacing the pressure vessel.

A replaceable cartridge for storing a fluid includes a pressure vessel for holding the fluid; a connecting line extending from the pressure vessel to a first connection surface on an external side of the cartridge; and a valve system comprising a first shut-off member disposed in the connecting line; wherein the connecting line has a taper in a direction of the first connection surface.
