A method for loading liquefied nitrogen (LIN) into a cryogenic storage tank initially containing liquid natural gas (LNG) and a vapor space above the LNG. First and second nitrogen gas streams are provided. The first nitrogen stream has a lower temperature than the second nitrogen gas stream. While the LNG is offloaded from the storage tank, the first nitrogen gas stream is injected into the vapor space. The storage tank is then purged by injecting the second nitrogen gas stream into the storage tank to thereby reduce a natural gas content of the vapor space to less than 5 mol %. After purging the storage tank, the storage tank is loaded with LIN.

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 coupling device for a cryogenic refueling arrangement, having a main valve; a venting valve which is connected parallel to the main valve and which serves for venting a volume, which is provided downstream of the main valve and the venting valve, in order to prepare the coupling device for a refueling operation; a housing which encloses a further volume in which the main valve and the venting valve are arranged; and a shut-off valve which is provided on the housing and by means of which the volume enclosed by the housing is accessible.

A method for operating a cryogenic refueling arrangement comprising a coupling device and a receiver socket, wherein the method comprises the following steps: a) coupling the coupling device to the receiver socket such that the coupling device and the receiver socket are locked to one another in a first position, b) applying a negative pressure to the coupling device and/or the receiver socket, c) unlocking the coupling device and the receiver socket so that the negative pressure causes the coupling device to move, in a direction toward the receiver socket, from the first position into a second position, which is different from the first position, d) locking the coupling device and the receiver socket in the second position, and e) starting a refueling process.

A coupling device (1) for a cryogenic refueling arrangement (3), having a valve (9), which is arranged between an inlet (5) and an outlet (7) of the coupling device (1), a primary drive mechanism (11) for opening and closing the valve (9), and a secondary drive mechanism (13) separate from the primary drive mechanism (11), wherein the primary drive mechanism (11) has a switch (10) which is connected upstream of the valve (9), and wherein the secondary drive mechanism (13) opens the switch (10) in order to close the valve (9) as soon as a pulling force (F) acting on the coupling device (1) exceeds a predetermined value.

A cryogenic tank-filling arrangement having a coupling device and a receptacle, wherein the coupling device and the receptacle are designed to be complementary to each other, wherein the cryogenic tank-filling arrangement can be brought with the aid of a pressure change in the intermediate space from an unlocked statein which the coupling device and the receptacle are accommodated in each other at least in sections, so that the coupling device and the receptacle enclose an intermediate space which is closed off relative to an environment of the cryogenic tank-filling arrangement and which is arranged between an end face of the coupling device and an end face of the receptacleinto a locked state, in which the end face of the coupling device is pressed against the end face of the receptacle due to the pressure change.

An LNG fueling station according to the present invention includes: an installation part on which an LNG tank container is installed, and a supply part for supplying liquefied natural gas from the LNG tank container installed on the installation part to an object for supply, wherein the LNG tank container can be transported and installed while storing the liquefied natural gas, and the LNG tank container is transported to the installation part and then installed on the installation part.

A set (10) for dispensing liquefied gas from a vessel (100) comprises a supporting structure (1), a pump (2) and a conditioning system (4). The supporting structure is designed for maintaining both the pump and the conditioning system inside the vessel when the set is in operation condition for dispensing a flow of liquefied gas. The set allows easy handling, simple fitting to the vessel and easy removal from the vessel because a main part of said set can be handled as a one-block element.
