A support device for an instrument on a loading/offloading tower of a tank of a ship is disclosed. The tower has multiple vertical masts linked to one another, pairwise, by struts extending on a strut axis, and a distal portion extending on a first axis, the distal portion being terminated by a first surface capable of forming a first surface contact with a strut extending on its strut axis substantially at right angles to the first axis. The installed first surface has a degree of freedom in rotation about the strut axis, a proximal portion extending on a second axis substantially at right angles to the first axis, linked to the distal portion. An installed fixing surface immobilized by fixing to the instrument has a degree of freedom in rotation about the second axis and a degree of freedom in translation on a third axis parallel to the second axis.

A compressed air storage container that stores compressed air is provided. The compressed air storage container includes a vertically disposed container closed at both ends and a separation film, wherein the container includes a side part, a top part closing an upper end of the side part, and a bottom part closing a lower end of the side part, includes a supply/discharge port for a first gas on the top part side, and includes a discharge/supply port for a second gas on the bottom part side. The separation film is hung from the top part with an opening at an upper end thereof being squeezed and hermetically sealed, an opening at a lower end is open against the bottom part, and a portion of the opening at the lower end is fixed such that it is sealingly attached to the bottom part or the side part.

A hydrogen supply system including: a plurality of hydrogen tanks that is attachable and detachable; a hydrogen consumption device that consumes hydrogen of the hydrogen tanks; and a control device is provided. The hydrogen consumption device includes an attaching-detaching mechanism including a plurality of motors that controls attaching and detaching of the hydrogen tanks with respect to the hydrogen consumption device, the motors corresponding to the attaching and detaching of the respective hydrogen tanks. The control device disposes, based on a temperature of each of the motors, a hydrogen tank of the hydrogen tanks to a hydrogen supply start position at which the hydrogen tank and the hydrogen consumption device are connected in a state in which the hydrogen tank is allowed to supply hydrogen to the hydrogen consumption device, or disposes the hydrogen tank to a hydrogen supply standby position.

A hydrogen filling device capable of suppressing mixing of water when filling a hydrogen tank with hydrogen. A hydrogen supply unit, a trap tank through which hydrogen supplied from the hydrogen supply unit, a main pipe which is a pipe extending from the trap tank, and a hydrogen supply branch pipe which is a pipe extending from the main pipe to the hydrogen tank, the trap tank includes a container portion, an inlet for flowing hydrogen into the container portion from the hydrogen supply unit, provided vertically above the inlet, and an outlet for flowing out the hydrogen from the container portion to the main pipe.

A liquid air energy conversion system is provided that recovers energy not by direct expansion of the liquid air stream, but rather by vaporization of the liquid air to form a first stream of very high pressure gaseous air via indirect heat exchange against a low pressure, cryogenic gas and subsequent sub-ambient or cold compression of the cooled, low pressure cryogenic gas to form a stream of moderate pressure gas. Both the stream of very high pressure gaseous air and the stream of moderate pressure gas are then warmed and expanded in one or more turbine expanders for production of shaft work and/or electrical energy.

Methods of, and control systems for, operating modular, liquid natural gas (LNG) manifold apparatuses, crossover systems for such modular manifold apparatuses, and systems including one or more of the modular manifold apparatuses and a plurality of ISO tank containers. The modular manifold apparatus includes an ISO container (e.g., an open-frame ISO container) with a plurality of container connection sections or bays, a liquid system, and a vent system, where each of the liquid and vent systems includes a header and a plurality of connection lines configured to be coupled to the respective liquid and vent connections of LNG containers adjacent the modular manifold apparatus.
