Definitions

  • IDS ABSTRACT Apparatus for transferring fluids between a ves- 7 W sel and the shore comprises a buoy anchored to the bottom of C films 2 rawmg the body of water on which it floats, and a pair of individually (52] 0.8. 1141230, rotatable turntables carried by the buoy.
  • the present invention relates to apparatus for assisting in the transfer of fluids in either direction between it vessel and the shore, more particularly of the type in which an anchored buoy provides mooring for the vessel and also a connection for the conduits through which the fluid flows.
  • conduit connections at the one side comprise a means to which the shore conduits can be fixed, the other side means to which floating lines can be fixed, the free end of which can be coupled to the piping on a vessel to be loaded or unloaded.
  • Said turntable becomes a very heavy structure when large vessels have to be moored to it.
  • said heavy turntable cannot be swinged by the force exerted on it by the floating lines as result of wind, currents and waves.
  • said floating lines will flex acutely with resulting damage to said lines and/or their connections.
  • Another object of the present invention is to provide such apparatus which will be relatively simple and inexpensive to construct, easy to operate, maintain and repair, and rugged and durable in use.
  • FIG. 1 is a side elevational view, partly in section, of apparatus according to the present invention.
  • FIG. 2 is a partial top plan view of the structure of FIG. 1, with parts broken away for clarity.
  • the present invention overcomes the above difficulties by providing the conduit connections and the vessel mooring means each with its own turntable.
  • the frame is in the form of a buoy 1 adapted to be anchored to the bottom of the body of water and to float thereon.
  • Buoy 1 com prises a floating annular body 2 having a central upright opening 3.
  • Connections 5 and 6 are carried by body 2 within central opening 3, for the purpose of connecting with the shore. These connections can be of conventional nature and need not be further described.
  • Connections 5 and 6 to the shore are interconnected with connections 7 to the vessel through a rotary head 4 that has a part 4a that is stationary with annular body 2 and in communication with the connections 5 and 6, and a rotating part 4b that is rotatable relative to part 4a about a vertical axis and which is fixed to and in communication withconnections 7.
  • connections 7 are fixedly secured to a turntable 8 which rotates about a vertical axis coaxial with rotary head 4 by means of a bearing 9 the inner race of which is carried by the outer side of stationary part 4a and the outer race of which is secured to turntable 8.
  • the turntable 8 carries a counterweight 10 which decreases the moments of force on the bearing 9.
  • the counterweight 10 consists of a hoist, but it may have any other suitable functional or nonfunctional form.
  • Turntable 11 Beneath but coaxial with turntable 8 is a second turntable 11 disposed between turntable 8 and body 2.
  • Turntable 11 rotates by means of a bearing 12 the inner race of which is fast with the body 2 and the outer race of which is fast with the turntable ll.
  • Turntable ll has an oblong rectangular shape and has a pivot 14 between its ends. To provide the pivot 14, a pair of coaxial pins 15 interconnect segments of the horizontal arm which form a part of the rectangular frame of turntable ll.
  • this vertically swinging portion of turntable ll functions in effect as a crossheadf
  • the axis of the pins 15 is horizontal and perpendicular to but horizontally spaced from the upright axis about which the portions of head 4 rotate.
  • roller assembly 16 pivotally interconnected with the outer end of the crosshead that swings about pivot M.
  • Roller assembly 16 rides between guide means provided by upper and lower rails 17 and 18 that are vertically spaced apart and that are carried by body 2 and that are disposed in pairs on opposite sides of the centerline 26 of roller assembly 16.
  • Roller assembly 16 depends through a slot 19 for this purpose.
  • the guideway in which roller assembly 16 runs is drained by discharge channels 20 for the water that would otherwise collect.
  • the turntable 11 can be made as heavy as necessary for being able to moor even the largest vessels, without altering the turntable 8.
  • the turntable can be as light as possible and is able to swing under the influence of the forces exerted to it by the floating lines, when no ship is connected to them.
  • the floating lines are protected against acute flexing and the damage caused by it.
  • the mooring cables and the conduits connected to the ship define an angle of about for instance.
  • the turntable 8 manually can be rotated until connections 7 and mooring means 13 are suitably angularly spaced from each other about their common axis of rotation. Also this can be effected by an operator in a small boat adjacent the buoy.
  • the turntables 8 and 11 can be interconnected by gears (not shown) to maintain or position them in a desired orientation.
  • turntable 8 It is also possible to avoid undesirable cantilever effects in turntable 8, particularly when the device 10 is used for supporting a heavy load, by supporting the cantilevered weight of turntable 8 on body 2 or on a subjacent portion of turntable ill.
