The invention relates to a pneumatic emergency shutdown system for a liquefied gas supply arrangement in which liquefied gas is supplied between a first tank and a second tank. The pneumatic emergency shutdown system comprises a pneumatic emergency shutdown circuit comprising pressure medium and provided in connection with the first tank and a pneumatic emergency shutdown link provided to the pneumatic emergency shutdown circuit, said a pneumatic emergency shutdown link connecting the pneumatic emergency shutdown circuit to a pneumatic controlling system of the second tank.

A storage system for storing a cryogenic medium, the storage system including a storage container for receiving the cryogenic medium. A gas removal line is configured to remove gaseous cryogenic medium from the storage container. A first heat exchanger is fluidically connected to the gas removal line and arranged outside of the storage container to heating the cryogenic medium. A second or in-tank heat exchanger is fluidically connected to the gas removal line and arranged downstream of the first heat exchanger and inside the storage container to heat liquid cryogenic medium in the storage container. A liquid removal line is configured to remove the liquid cryogenic medium from the storage container. A controllable first shut-off valve is arranged in the gas removal line, and a controllable second shut-off valve is arranged in the liquid removal line.

Systems and methods are provided for a modular compressed natural gas (CNG) fueling station. The modular CNG fueling station modules include a control station skid, an interface module, and a compressor skid. The compressor skid includes a fueling station for fueling a compressed natural gas (CNG) vehicle. Each of the modules of the modular CNG fueling station are configured as fully wired “plug and play” station modules. The control station module, the interface module, and the compressor module are each pre-plumbed with electrical connections to allow the CFS station to be portable and easily installed above-ground at a utility site.

A gas supply marine vessel and a refueling facility are described. The gas supply marine vessel includes a hull with an upper deck having an elongated cargo cavity formed therein. Gas interface modules are disposed in the cavity and extend between hull sides, each module having a plurality of fuel vessel docking stations. A plurality of stacked fuel container assemblies are fluidically coupled to the docking stations. A gantry, is movable along the length of the cavity, straddles the cargo cavity between hull sides. An articulating crane is mounted on the gantry and it utilized to move fuel container assemblies to a fuel container depression formed in the deck of a floating refueling facility. The floating refueling facility includes a concave side to facilitate mooring adjacent a shoreline, the concave side forming angled extensions at corners of the deck with a linkspan extending from each of the angled extensions.

A system for dispensing cryogenic liquid includes a container defining an interior with a partition dividing the interior into primary and reserve chambers. Cryogenic liquid within the primary chamber is separated from cryogenic liquid in the reserve chamber. The partition provides a headspace cornrnurrrcation passage. A primary pressure building circuit has an inlet selectively in liquid communication with the primary chamber and an outlet in fluid communication with the headspaces of the primary and reserve chambers. A reserve pressure building circuit has an inlet selectively in liquid communication with the reserve chamber and an outlet in fluid communication with the headspaces of the primary and reserve chambers. An equalizing circuit is selectively in liquid communication with the primary and reserve chambers. A dispensing line is selectively in liquid communication with the primary chamber.
