  • thrust means operable to rotate the rigid arm relative to the first vessel about a substantially vertical axis in use
  • position monitoring means to monitor the separation of a point on the arm and the second vessel
  • a control system operable to actuate the thrust means if the separation is outside a predetermined range, so as to move the arm relative to the second vessel thereby to restore the separation to within the predetermined range.
  • the apparatus may usefully comprise mooring means to moor the apparatus to the second vessel, means to monitor whether the mooring means is attached to the floating vessel and means to automatically disconnect the loading device from the second vessel if the mooring means becomes detached from the second vessel.
  • the apparatus may also include mooring means to moor the second vessel to the first vessel, means to monitor whether the mooring means is attached to the second vessel and means to automatically disconnect the loading device from the second vessel if the mooring means becomes detached from the second vessel.
  • control means is preferably operable to actuate the thrust means to move the arm away from the second vessel.

  • the invention also provides a method as claimed in claim 17 of transferring fluid from a first vessel to a second vessel using the apparatus as described above, comprising the steps of: actuating the thrust means to pivot the arm in a first direction about an axis defined by the attachment means relative to the first vessel, moving the second vessel into a position in the vicinity of the first vessel, actuating the thrust means to pivot the arm in a second direction opposite to the first direction so as to bring the loading means adjacent the second vessel, connecting the loading means to the second vessel and transferring fluid from the fluid conduit to the second vessel, disconnecting the loading means from the second vessel, and actuating the thrust means to pivot the arm in the first direction away from the second vessel; wherein, while the loading device is connected to the second vessel, monitoring the separation between a point on the arm and the second vessel, and operating the thrust means if the separation is outside a predetermined range so as to move the arm relative to the second vessel, thereby to restore the separation to within the predetermined range.
  • the method may further comprise the step of monitoring whether mooring means on the arm is attached to the second vessel and in the event of detachment, automatically disconnecting the loading device from the second vessel.
  • the method may further comprise the step of monitoring whether mooring means on the structure is attached to the second vessel and in the event of detachment, automatically disconnecting the loading device from the second vessel.
  • the thrust means is preferably operated to move the arm in the first direction away from the second vessel.
  • a first floating vessel 10 which may be a production or storage vessel moored to the seabed by any conventional and appropriate means.
  • the transfer apparatus 12 is shown in use, connecting the two vessels 10,11.
  • the transfer apparatus 12 consists of a submerged rigid arm 13, typically of space frame type construction. As shown in Figure 2 , the arm 13 may be formed of three longitudinal members 14 arranged in a triangular form and joined by a number of transverse bracing members 15.
  • Piping 16 for example rigid steel piping, is attached to the arm and carries the fluid being transferred.
  • the piping 16 may be located inside one or more of the longitudinal members 14 and insulation (not shown) may also be provided. This construction protects the piping 16 but also allows the possibility of inspection of the piping 16.
  • attachment means 17 is provided for attaching the arm 13 to the first vessel 10, preferably at the stern.
  • the attachment means 17 may be constructed in any convenient form which includes articulations allowing the arm 13 to pivot about at least two axes relative to the vessel 10, preferably the vertical axis 18 and the horizontal axis extending perpendicularly into and out of the plane of the paper.
  • the attachment means 17 projects downwardly from the vessel 10 and is dimensioned such that the arm 13 is located underwater at a depth greater than the maximum draught of both the first and second vessels 10, 11.
  • float means 19 is provided which extends upwardly from the arm 13 and projects above the water surface.
  • a loading device 20 which is preferably a cryogenic loading device of known form, is located on the top of the float means 19. Articulations may be provided to allow the loading device 20 to pivot relative to the float means 19.
  • the loading device 20 is connected to the piping 16 and is connectable to the second vessel 11 to allow transfer of fluid from the piping 16 to the vessel 11.
  • the loading device 20 is configured to allow fluid pumped from the first vessel 10 to be readily returned to it, for example in the case of an emergency disconnect from the second vessel 11.
  • the piping 16 is preferably provided with flexible connections such as swivel joints or flexible hoses where necessary to allow it to bridge the various points of articulation in the apparatus 12.
  • the rigid arm 13 is preferably designed to be of a suitable length such that in use, when the proximal end is attached to the stern of the first vessel 10, its distal end will be adjacent a midship portion of the second vessel 11.
  • one or more thrusters 21 is located at the lower end of the float member 19.
  • the or each thruster 21 is powered and controlled from the first vessel 10, for the purpose described further below.
  • the thrusters 21 are used to rotate the arm 13 about the vertical axis 18, for example to rotate it anti-clockwise if viewed from above in Figure 1 , so that it does not obstruct the area around the stern of the first vessel 10.
  • the second vessel 11 can then be manoeuvred into position adjacent the first vessel 10 as shown in Figure 1 .
  • the first and second vessels 10, 11 may now be moored stern to bow by a line 22, for example an elastic line, as shown in Figures 1 and 3 .
  • the thrusters 21 are operated again to rotate the arm 13 in the opposite direction, (clockwise when viewed from above in Figure 1 ) to bring the float means 19 and loading device 20 adjacent preferably the midship portion of the second vessel 11.
  • the rigid arm 13 is moored to the vessel 11 by any suitable mooring means, such as mooring lines 23 shown schematically in Figure 1 .
  • the loading device 20 is connected to the appropriate fluid receiving apparatus on board the vessel 11 so that fluid from the piping 16 can be transferred to the second vessel 11.
  • the mooring means 23 is disconnected from the vessel 11.
  • the thrusters 21 are then operated to rotate the arm 13 away from the vessel 11, allowing it to leave the area unobstructed.
  • the thrusters 21 are also employed to maintain the rigid arm 13 in a substantially fixed position relative to the vessel 11, to ensure that no unacceptable loads are imposed on the loading device 20 and various interconnections between the piping 16 and the vessel 11.
  • a position monitoring device 24 is mounted on a point on the transfer apparatus 12, for example on the float means 19, to monitor continuously the separation of that point from the hull of the vessel 11.
  • the position monitoring device 24 may act by electronic or visual means.
  • a control system 25 preferably located on the first vessel 10 receives information from the position monitoring device 24. If the transfer apparatus 12 and the vessel 11 move towards or away from one another so that their separation is no longer within an acceptable range, the control system 25 responds by operating the thrusters 21 to move the transfer apparatus 12 in an appropriate direction so as to restore the transfer apparatus 12 and the vessel 11 to within an acceptable separation range. In this way, any relative movement due to the action of wind and waves can be accommodated to avoid the risk of damaging the transfer apparatus 12 and/or the vessel 11.
  • the apparatus also comprises means 26 to monitor whether the mooring means 23 is actually attached to the vessel 11 and/or whether the line 22 is attached to the vessel 11. If the mooring means 23 and/or line 22 become accidentally detached from the vessel 11, the control system 25 operates to automatically disconnect the loading device 20 from the vessel 11, to avoid any damage to the loading device 20 which might occur if the separation of the vessel 11 and the transfer apparatus 12 changes significantly due to detachment of the mooring means 22,23.
  • control system 25 operates in this way to disconnect the loading device 20 from the vessel 11, it also operates the thrusters 21 to move the rigid arm 13 well away from the vessel 11, to avoid the danger of collision.
  • the transfer apparatus 12 When the transfer apparatus 12 is not being used, it may have its distal end secured to the first vessel 10. For example, if the transfer apparatus 12 is attached to the stern of the vessel 10, it can be pivoted back round so that its distal end can be secured to the vessel 10 towards the bow region as shown in dotted lines in Figure 3 . In this way the transfer apparatus 12 is able to withstand extreme weather conditions which may exceed its design parameters. It also allows inspection, repair and maintenance to be carried out more easily.
  • the fixed structure may comprise a base 27 mounted on the seabed from which a column 28 rises to above the surface of the water.
  • the base 27 may be a well-head, or connected by a seabed pipeline to a well-head or onshore plant.
  • the arm 13 is attached to the column 28 by articulated attachment means 17 and the vessel 11 may be moored to the column 28 by a line 22.
  • the other features are the same as in the first embodiment.
  • FIG. 5 An embodiment of transfer apparatus 12 of the present invention is shown in Figure 5 for transfer between two floating vessels 10, 11. This is generally similar to the apparatus of Figure 1 . However, in this case, at its first, proximal end the arm 13 includes an upward projection 13a which extends up above the waterline and is connected to the first vessel 10 by attachment means 17.
  • the attachment means 17 may be constructed in any convenient form which includes articulations allowing the arm 13 to pivot about three axes relative to the vessel 10, preferably the vertical axis 18, a horizontal axis extending into and out of the plane of the paper and a horizontal axis parallel with the plane of the paper.
  • the upward projection 13a and the attachment means 17 are sized such that the horizontal portion of the arm 13 is located underwater at a depth greater than the maximum draught of both the first and second vessels 10, 11. This construction allows easier access to the attachment means 17 for inspection, maintenance and repair.
  • the float means 19 at the distal end of the arm 13 preferably incorporates at least one and preferably two buoyancy devices 31, 32 as shown in Figure 7 .
  • the buoyancy devices 31, 32 are substantially cylindrical members which are mutually spaced and project both above and below the waterline.
  • the piping 16 is located inside a conduit or tunnel 30 which extends the length of the arm 13, for example within the space frame construction, as seen in Figure 6 .
  • the tunnel 30 has an opening above the waterline at the proximal end of the transfer apparatus 12 and extends continuously to another opening above the waterline at the distal end.
  • the tunnel 3G and openings are designed to permit personnel entry and movement therealong. In this way the entire length of pipeline 16 is accessible in a substantially dry environment for inspection, repair and maintenance, avoiding the need for divers.
  • the piping 16 is preferably provided with flexible connections such as swivel joints or flexible hoses where necessary to allow it to bridge the various points of articulation in the apparatus 12.
