Definitions

  • the present invention relates to apparatus for assisting in the transfer of fluids in either direction between a 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.
  • mooring buoys of this type are subject to icing in cold climates.
  • a heavy icecap forms on the buoy, there is danger that the buoy may capsize, or at least sink so low in the water that its use is hampered.
  • ice can impede the relative movement of various parts of the buoy.
  • Another object of the present invention is to provide mooring buoys in which icing is completely or largely prevented.
  • FIG. 1 is a side elevational view, partly'in section, of a mooring buoy according to the present invention
  • FIG. 2 is an enlarged fragmentary side cross-sectional view of a portion of a cover for a mooring buoy according to the present invention
  • FIG. 3 is a view similar to FIG. 2, but showing a different embodiment thereof.
  • FIG. 4 is a fragmentary side cross-sectional view of a portion of a cover of a mooring buoy according to the present invention, showing still another embodiment thereof.
  • the present invention overcomes the above difficulties by providing a cover for the buoy which is rotatable with the turntable and which is heated to impede the formation of ice thereon.
  • the buoy may also be heated adjacent the margins of the cover, and also adjacent the bearings of the turntable. Heating may be effected'electrically, or by a relatively warm fluid such as sea water, closed cycle fresh water, or the fluid itself which is being handled.
  • mooring buoy 1 is provided with means (not shown) to anchor it to the bottom of the body of water, so that buoy 1 will float thereon.
  • Buoy 1 comprises a floating annular body 2 having a central upright opening 3.
  • Fluid 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 and 9 to the vessel through a rotary head indicated generally at 4, that has a lower part that is stationary with annular body 2 and in communication with the connections 5 and 6, and a rotating upper part that is rotatable relative to the lower part about a vertical axis and which is fixed to and in communication with connections 7 and 9.
  • Connections 7 and 9, in turn, are fixedly secured to a turntable 8 which rotates about a vertical axis coaxial with rotary head 4 by means of conventional bearings whose inner race may, for example, be carried by the outer side of the stationary part described above and the outer race of which may be secured to turntable 8.
  • the present invention is characterized in that a shield-like protective cover 10 in the form of an inverted bowl is mounted coaxially on and rotatable with turntable 8 by mounting means (not shown), the cover 10 being sufficiently large to cover the entire upper portion of the mooring buoy and to somewhat overlap the upper outer edges of the body 2 in close proximity therewith.
  • Connection 7 passes through cover 10 and has no movement relative to cover 10.
  • a space 11 is confined between'the underside of cover 10 and the upper deck of body 2, and it is in this space 11 that turntable 8 and the exposed portions of rotary head 4 are disposed.
  • a plurality-of electrical conductors 12 are provided on the underside of cover 10, and are preferably arranged so as to extend radially from the center of cover l 0 toward the sides; although they may be arranged in other patterns.
  • Conductors 12 are enclosed in U-shaped metal channels 13 or L-shaped metal channels 14 attached to the underside of cover 10 as by welding.
  • Electrical power means (not shown) are provided for passing alternating current through the conductors 12 thereby to convert electrical energy into heat energy by electrical induction.
  • power may be supplied from shore at 800 kilowatts and 6.6 kilovolts and may be converted by one or more transformers on the buoy itself.
  • control and switching and measuring apparatus may be operated remotely from the shore.
  • the power source might be carried by the buoy itself.
  • FIG. 4 Another heating arrangement is shown in FIG. 4, in which the cover 10' is comprised of two parallel shells having a space 15 therebetween which may be channeled or not for the radially outward flow of a heating fluid between the shells.
  • I-Ieating fluid may be supplied through an inlet 16 and through an electric heating coil 17 and may leave through outlet 18 at the margins of cover 10.
  • the pump is preferably driven by electricity.
  • the heating medium can be sea water or closed cycle fresh water.
  • heating devices 20 similar to those shown in FIGS. 2 and 3 are provided in the upper outer portions of body 2.
  • heating elements 19 such as those shown in FIGS. 2 and 3, at the upper inner margins of body 2 about opening 3, that is, beneath the turntable bearings.
  • a mooring buoy for transferring fluids between a vessel and the shore, comprising a buoyant body adapted to be anchored to the bottom of a body of water, a plurality of elements secured to the upper surface of said buoyant body, said elements comprising means for the attachment of at least one first'pipe from the shore, means for securing a vessel to the buoy and means for the attachment to said first pipe of at least one second pipe leading to said vessel, 21 shield-shaped protective cover over the mooring buoy, the cover being in the form tion for all of said plurality of elements against environmental conditions, and means for heating the upper outer edges of the body adjacent the margins of the cover.
  • a mooring buoy for transferring fluids between a vessel and the shore, comprising a buoyant body adapted to be anchored to the bottom of a body of water, a plurality of elements secured to the upper surface of said buoyant body, said elements comprising means for the attachment of at least one first pipe from the shore, means for securing a vessel to the buoy and means for the attachment to said first pipe of at least one second pipe leading to said vessel, a shield-shaped protective cover over the mooring buoy, the cover being in the form of an inverted bowl whose margins closely overlie the upper outer edges of the body, said bowl constituting a complete enclosure of the buoy's upper surface, thereby providing protection for all of said plurality of elements against environmental conditions, a turntable mounted on and rotatable relative to the upper side of the body, the turntable and the cover being rotatable together as a unit, bearings by which the turntable is mounted for rotation on and relative to the buoy about an upright axis, and heating means carried by the body adjacent the turntable bearings to
