Definitions

  • the present invention relates to a hinged device for transferring fluids from a first location to a second location, for example from an oil installation at sea to a tanker or other marine vessel.
  • Fluid transfer devices of the accordion type or with deformable diamonds are known.
  • a single broken line is used for transferring a liquid and is constituted by articulated hollow elements, while the other broken line is produced by any articulated connecting elements.
  • the assembly is articulated respectively to a support arm and to a connector.
  • the articulation with the carrying arm can be a universal joint, while the connector is a funnel or bell device suitable for fitting on a hollow nozzle head disposed on a ship.
  • the operation of the articulated assembly is obtained using a cable.
  • the assembly is completed by a hawser coming to be fixed to the connector.
  • a transfer device is also known of the accordion or deformable diamond type in which two broken line paths are used for the transfer of fluids but the assembly is joined in an articulated manner and definitive with two coaxial terminations inseparable from their respective supports.
  • a composite rotating joint is provided, but no operating means (such as a cable) for deployment or retraction of the deformable diamond system is provided, since the terminations are inseparable from their supports. respective.
  • a deformable transfer device 1 comprises two upper pipes 11, 12 the upper end of which is pivotally connected to the end of an arrow 2 (only sketched in broken lines in FIGS. 1 and 2 ) and more specifically to respective pipes 21, 22, carried by the latter, by means of connection means 3, two lower pipes 13, 14, the lower end of which is connected to a tanker 4 of which only an upper wall is shown in broken lines in FIG. 1 by means of connection means 5 of the deformable transfer device to the boat and of connection means 6 of the deformable transfer device, and two intermediate conduits 15, 16 interposed respectively between the lower end of each upper pipe and the upper end of the corresponding lower pipe.
  • Each of the two assemblies consisting of an upper pipe 11, 12, an intermediate pipe 15, 16 and a lower pipe 13, 14, which connects a pipe 21, 22 of the boom to the boat, one for the transfer of liquefied natural gas, the other for the return of steam, is constituted in the form of a broken hinged line placed opposite each other as shown in Figure 1; these two sets are not in the same plane, but in planes arranged in parallel, and are placed so as to constitute, seen from the front, two articulated diamonds of which two respective angles are opposite by the vertex, this vertex being in the middle of the conduits intermediate 15, 16, which are secured at this location by a hinge, for example a ball joint 17; so both diamonds formed, arranged one above the other, remain equal to each other in all positions of the deformable transfer device.
  • the tower or the vertical carrying device which is mounted by its base on a platform forming part of the installation at sea is not shown, and it has been seen that the same is true of most of the boom, in particular of its end pivotally attached to the top of the carrier device; a support and actuation device with cables is also provided, cooperating with a tensioning device, the characteristics of which will be explained below; a securing device is used to secure the deformable transfer device to the boom.
  • Each intermediate pipe is connected by its respective ends on the one hand to an upper pipe and on the other hand to a lower pipe, by means of articulations 18, which can be of single knee, each provided with a rotating joint and at minus a fixing with fixed flanges whose respective axes are perpendicular or orthogonal, or, as shown in the drawings, of the "double knee" type, - each provided with a pair of rotary joints 181 whose respective axes are in the extension l 'one of the other and fixings with fixed flanges 182 whose respective axes are also in the extension of one another and parallel to the first; whereas with simple knee joints, it is easier to produce each of the two assemblies consisting of an upper pipe, an intermediate pipe and a lower pipe in the form of a broken line, the three segments of which are in two (or three) parallel planes, with double knee joints, it is easy to make a broken line whose three segments are in the same plane.
  • articulations 18 can be of single knee, each provided with
  • connection means 3 of the deformable transfer device to the lines 21, 22 of the boom comprise on each line a single knee 31 to allow extensions and retractions of the arm, with a pair of cryogenic rotary joints 311, 312 having their axes perpendicular so as to make a coupling of the "cardan" type.
  • connection means 5 of the deformable transfer device with the boat may have an axial rotary joint; however, this is not essential and here they comprise two independent lines each provided with a knee 51 to allow extensions and retractions of the arm, with rotary joints 511, 512 having their axes perpendicular so as to also carry out a coupling of the gimbal type, a safety valve 513, a hemispherical ball valve 514, and locking members 515; the connection means 5 also comprise a central locking head 516, connected here to the two lines by flanges; the safety valves 513 and the locking head 516 are provided on the one hand with shutters and on the other hand with quick disconnection members 517 represented symbolically, so that in case of emergency disconnection, the lower part of these valves and the locking head remain on the ship, the jet being moreover blocked by its own weight or if necessary by spring devices provided respectively on the two parts of these valves and of the locking head which are to be disconnected , so that the shutters are then automatically pushed into their closed
  • connection means 6 of the boat to the transfer device can take different forms.
  • the connection between the deformable transfer device and the tank is carried out by means of a single pipe 61, with a rotary joint 611 of the bi-product connection type, allowing the passage of liquefied natural gas and steam in circuits isolated from one another, for example concentric; it is also possible to provide, as in FIGS. 5 and 6, two lines 62, 63 each comprising three rotary joints such as the joints 621, 622, 623 of line 62, of vertical axis, forming an articulated connection around a central pipe 64 equipped with a rotary joint 641 and connected to the two lines by flanges.
  • the central pipe allows the passage of a supply cable connected to the lower part of the deformable transfer device and used to bring it into the working position, and comprises locking members 65 for the head.
  • locking 516 which is fixed at this location when the connection phase is completed; in both cases also, the connection means 6 also comprise, in their region where they are locked to the connection means 5, a hemispherical ball valve 624.
  • the support and actuation device comprises two cables 71, permanently on the structure; these two cables, connected to the tensioning device 72 via pulleys 72A arranged at the top of the arm, are attached to the lower part of the deformable transfer device.
  • the tensioning device is designed so that on the one hand the arm has an equilibrium position just above the zone of maximum movements encountered during loading, and on the other hand it rises to its equilibrium position. without oscillation when disconnected at the end of loading, and also that in all cases of normal or emergency disconnection, its upward acceleration is greater than the acceleration of the ship; the folded position of the deformable transfer device is shown in long dashed lines in FIG. 1.
  • the securing device is designed such that, from its equilibrium position, the deformable transfer device is secured to the boom by means of claws which lift it and support it in its securing position.
  • the articulated transfer device according to the invention which can be fitted with members intended for cryogenic type operation, in particular cryogenic rotary joints, allows rapid connection and disconnection with the tanker, under good conditions of balance and safety, thanks to its double diamond arrangement in pantograph operated by cables connected to a tensioning device designed to respond to extremely severe requirements, a number of components located at the bottom of the device being liable to remain attached to the tanker in the event of an emergency disconnection.
  • two dog legs (62, 63) each having three rotations, such that the rotary joints (621, 622, 623) of the leg (62) each form a transfer line articulated around a central mast, couplers at the ends of the dog legs coming to couple at the ends of the deformable transfer device.
  • each transfer line or dog leg with three rotations of these coupling and transfer means further comprises, two other rotations with a horizontal axis, the combination of the five rotations allowing vertical movement of the couplers and a final connection at the ends of the arm.
  • Each dog leg (62 or 63) therefore shows two other rotations (A and B) in addition to the three rotations (621 - 622 - 623) for the leg (62) and (631 - 632 - 633) for the leg (63 ).
  • the rotation (A) is arranged between the coupler (C) and the rotation (621) or (631) depending on whether it is the leg (62) or the leg (63).
  • the rotation (B) is arranged between the rotations (622 and 623) for the leg (62) and between the rotations (632 and 633) for the leg (63).
  • the elbow (8) connecting the coupler (C) to the rotation (A) is pivotally mounted at the end of a console (82) carried by a sleeve (821) for the leg (62) and at the end of a console (83) carried by another sleeve (831) for the leg (63).
  • the sleeves (821) and (831) are arranged one above the other and are capable of sliding on the mast (M).
  • the pivoting takes place along a general axis (X-X) passing through the center of the rotations or rotary joints (A) and using jacks (VI) advantageously supported on the rotations (621) and (631).
  • V2 Other cylinders (V2) are provided to obtain a vertical translation of the sleeves (821) and (831) along the mast (M).
  • Another cylinder (V3) is provided to obtain a rotation on itself of the mast (M) around the axis (Z-Z).
  • the rotation (B), also with a horizontal axis (Y-Y), ensures, when combined with the rotation (A) and the three rotations forming the dog leg, a vertical movement of the coupler. This allows more reasonable manufacturing tolerances, since the assembly is not hyperstatic.
  • the dog legs are not subject to mechanical forces due to a differential contraction between the dog legs and the locking mast (M) the latter remaining at room temperature when the dog legs cool.
