DETAILED DESCRIPTION OF THE INVENTION

(10) As illustrated in [FIG. 1], the fluid transfer installation 1 is intended for the transfer of fluid (in particular a cryogenic fluid such as liquefied hydrogen) between a source 9, 10 and a receiving unit 16, in particular the reservoir of a boat.

(11) The source comprises, for example, a mobile storage facility 9 for supplying liquefied fluid and/or a fixed or mobile filling station 10.

(12) The installation 1 comprises a tower 2, for example of parallelepipedal general shape, with a beam framework structure, for example a lattice structure. That is to say that the tower 2 may comprise a scaffolding formed by rigid rods or bars, for example metal bars assembled by, preferably demountable, fixing members. The tower 2 may comprise in its interior a ladder system 13 or stairway allowing an operator to climb there (cf. [FIG. 2] or [FIG. 4] for example). One or more intermediate floors 17 may be provided between the lower end and the upper end.

(13) The tower 2 houses part of a fluid transfer circuit 4, 14, 19 which comprises in particular a first pipe 4, 14 extending between a first lower end intended to be connected to the fluid source 10 and a second upper end 14 intended to be connected to the receiving unit 16.

(14) Thus, at least part of the transfer circuit 4, 19 is housed within the volume delimited by the structure of the tower 2.

(15) The tower 2 is composed of at least two preconstructed modules 12, 22 stacked in a separable manner allowing two different configurations of the tower 2 and respectively having different heights.

(16) In a first configuration, the two modules 12, 22 are stacked (assembled), cf. [FIG. 2]. The structures (the frames) of the two modules 12, 22 may be connected to one another by nesting and fastened by bolted or splice plate-type connections, or any other suitable mechanical connection. The assembly may be carried out on the site (quay, for example) where the operation takes place.

(17) The total height may be of the order of 12 m, for example.

(18) In the second configuration, a single module 12 of the modules is used. The height may then be of the order of 5 m to 6 m, for example. Of course, this height is not limiting and could be greater or less (preferably as long as the transport conditions in normal road mode are observed).

(19) The lower module 22 may have a height that is less than the upper module 12 (or vice versa, or an equal height).

(20) The tower 2 may be fastened to the ground by, for example, stud shooting (anchoring in concrete for example). Any other fastening method may of course be envisaged.

(21) As illustrated, this modular structure makes it possible to adapt to different sizes of ships (in particular the height of access to the deck). The tower 2 is thus modular (in the example illustrated, two nestable substructures 12, 22 are provided but more than two modules are conceivable). These modules 12, 22 make it possible to manage access to variable ship heights, for example from zero to more than 15 m. This modularity makes it possible to facilitate standard road transport of the tower 2 by limiting the length excluding accessories.

(22) Thus, to remain compatible with normal road transport (excluding abnormal load width), the modules 12, 22 of the tower 2 preferably have a maximum width of 2.5 m and a maximum height of 3.8 m approximately when the modules are in a recumbent horizontal position. That is to say that the footprint of the tower or of the modules in a vertical position does not exceed 2.5 m3.8 m.

(23) The transfer circuit 4 situated within the volume delimited by the tower 2 comprises at least two adjacent sections 40 situated respectively at two adjacent ends of the two modules 12, 22.

(24) FIG. 8 schematically illustrates the principle of connecting the two sections 40 of the circuit 4 at the junction between two modules 12, 22 (non-assembled position on the left, assembled position on the right).

(25) These sections 40 are connected to one another via a demountable system, for example with flanges or with collars 34 configured to make it possible to adapt the transfer circuit 4 to the two configurations. The fastening of the flanges 34 preferably occurs without welding (connection by bolted flanges or collar-type flanges, for example by screwing or the like).

(26) The transfer circuit 4 situated within the volume delimited by the tower 2 preferably comprises rigid pipes mounted on the structure of the tower 2 via supports 60, at least some of which can be mounted so as to be adjustable in position relative to the structure of the tower 2. For example, the supports 60 of the rigid pipes 4 are mounted so as to be adjustable in a vertical position relative to the structure of the tower 2 (slidably for example) and/or transversely to the vertical direction of the tower 2. For example, these supports 60 can be adjustable along the three axes in space.

(27) As illustrated, in order to facilitate joining, at least one of the sections of the circuit 4 may comprise a flexible portion 24.

(28) Preferably, the tower 2 further comprises a gangway 6. The gangway 6 is mounted pivotably relative to the tower 2 between a deployed position extending transversely to the tower 2 (cf. [FIG. 5] and [FIG. 7]) and a retracted (raised) position extending along the tower 2 (cf. [FIG. 4] and [FIG. 6]). This pivoting movement of the gangway 6 may be achieved by the fact that a portion of the gangway 6 is mounted on pivots for articulating about a horizontal axis, for example. This pivoting movement makes it possible to compensate for the height variations of boats caused, for example, by the sea level variations associated with tidal phenomena.

(29) Furthermore, the gangway 6 is preferably mounted in a vertically slidable manner on the tower 2 (cf. the upper position in [FIG. 6] and lower position [FIG. 4]).

(30) The gangway 6 thus allows access to the deck of a ship 16 whatever the height (for example up to 15 m or more). This vertically positionable gangway 6 is also retractable (raisable) in order to be able to be disengaged from the ship. The sliding movement of the gangway 6 over all or part of the height of the tower 2 makes it possible to adapt to the altitude of the access deck of the ship 16.

(31) As schematically illustrated particularly in [FIG. 5], the gangway 6 is, for example, mounted slidably on the tower 2 via a system of rails 7 (or slideways). The sliding mechanism may be actuated manually or electrically, for example. This structure makes it possible to adapt and configure rapidly to access deck heights which can be variable between different types of boats 16 to be supplied.

(32) As schematically illustrated in [FIG. 1], the second end of the first pipe 4 of the transfer circuit may comprise a flexible transfer hose 14 which extends towards the outside of the tower 2 in order to be connected to the reservoir 16 to be filled. The terminal end of the flexible hose 14 can be provided with a quick connector having self-closing valve(s). The other end of the flexible hose 14 is preferably connected in a demountable manner to the (rigid) central part of the first pipe 4. The tower 2 preferably has a support bracket 8 for supporting said flexible transfer hose. The bracket 8 extends transversely to the tower 2.

(33) The bracket 8 for holding the flexible transfer hose 14 makes it possible to adapt to the height of the access deck, which may be different depending on the ships, and according to the tidal height, where appropriate. The flexible transfer hose 14 is preferably adjustable in position. For example, the flexible hose 14 can slide vertically by means of a slideway (or rail) positioned on the structure of the tower 2 (laterally or frontally, for example). The sliding mechanism may be actuated manually or electrically. Thus, just like the gangway 6, the bracket 8 may be vertically slidable to adapt and configure rapidly to access deck heights which can be variable between different types of boat to be supplied.

(34) The bracket 8 is preferably articulated about a vertical axis allowing it to be folded onto the flank of the structure of the tower 2 (in order to disengage from the ship, for example, and/or for transport of the tower 2). A fastening system may be provided to keep the bracket in the chosen position.

(35) In [FIG. 4] and [FIG. 5], the bracket 8 is represented schematically. It comprises, for example, a first arm which extends vertically along the tower 2 and an upper end of which is connected to a second arm which extends transversely with respect to the tower 2. The bracket 8 is, for example, articulated on a hinge about a vertical axis via a structure connected to one side of the tower 2. The bracket 8 is in a position facing laterally towards the side in [FIG. 4] and [FIG. 5].

(36) As can be seen in [FIG. 1], the transfer circuit comprises a second pipe 19 forming a chimney 19 for evacuating vent gases. This chimney 19 comprises a lower end which can be connected to the fluid source 10, for example to the fluid delivery station. The chimney 19 comprises an upper end preferably projecting at the upper end of the tower 2 to release the pressurized gas.

(37) It should be noted that the principle of connecting in sections that is illustrated in [FIG. 8] can also be applied to this second pipe 19.

(38) As can be seen in [FIG. 6] and [FIG. 7], this second pipe 19 situated within the tower may comprise a plurality of connection ends 41 which are vertically distributed and configured to allow the connection of an end of the flexible transfer hose 14. This makes it possible to position the second end 41 of the transfer circuit at different altitudes. When they are not connected to the flexible transfer hose 14, these connection ends 41 are closed in a sealed manner by demountable flanges, for example.

(39) These connection ends 41 may be tapping points for an end of the flexible transfer hose 14, for example at each stage of the tower 2. This allows the connection of the flexible transfer hose 14 during the standby phases (no ships to be supplied) between two liquid transfer phases.

(40) This or these tapping points 41 may be used in order to ensure completely safe evacuation of the gaseous hydrogen which may be contained in the circuit. These ends 41 may also serve to mechanically protect the end of the flexible transfer hose 14 in order not to damage its mechanism and its meeting plane.

(41) These connection ends 41 also make it possible to ensure a heating function in order in particular to have an end flange close to the ambient temperature so as to avoid trapping moisture at the moment of connecting with the interface of the reservoir 16 to be filled and thus avoid possibly blocking the mechanism of this end flange (icing).

(42) This makes it possible to avoid polluting the fluid (for example the liquid hydrogen) contained in the storage facility of the boat 16.

(43) These multiple connection points 41 at different levels or stages make it possible to prevent an operator from having to manage the handling of the flexible transfer hose 14 from one level of the tower 2 to the other (via stairways 13). Specifically, in the case of a single connection point 41, the operator would be forced to raise or lower the terminal end of the flexible transfer hose 14 within the tower 2 in order to adapt to different heights while maintaining the connection point 41 at a different altitude. The proposed architecture optimizes ergonomics, safety and also the operating time.

(44) As schematically illustrated in [FIG. 1], the lower end of the first liquid transfer pipe 4 may be connected to the lower end of the second pipe 19 (gas evacuation chimney), for example at the source station 10, via circuitry 15 provided with a set of valve(s). Thus, the evacuation of gas in the transfer circuit may be achieved via this circuitry (the gas circulating downwards in the first pipe 4 of the transfer circuit and then joining the lower end of the second pipe 19 (chimney) via the circuitry 15 in order then to be evacuated to the atmosphere at the top.

(45) Thus, the first pipe 4, 14 of the circuit allows the transfer of liquid between the fluid source 9, 10 and the boat 16, while the second pipe 19 can be used for the evacuation of gas via an upper chimney for all the vent gases emanating from the circuit (vent gas of the first pipe 4, 14 and/or of the circuitry 15 and/or of the source 9, 10).
