Definitions

  • ABSTRACT A cargo transfer system including a rack for the storage, retraction and paying out of a hose used in the transfer of cargo is mounted on a moored storage terminal (e.g. a permanently moored vessel or other suitable storage facility).
  • the system includes means for mooring a tanker in tandem with the moored storage terminal and means such as a manifold for connecting the cargo hose between the terminal and the tanker.
  • the rack is arranged to be raised and lowered by means of a hoist on the floating storage terminal.
  • tandem mooring of vessels is feasible in seas up to feet, which isconsidered to be a relatively severe environment.
  • a tandem mooring system utilizes a permanently moored storage member or float such as a tanker, to load a shuttle tanker or offtaker.
  • the present invention relates to a novel cargo transfer system' employing tandem mooring.
  • the invention includes a permanently moored floating, offshore attended terminal (e.g., a tanker or specially designed storage vessel) which for convenience is referred to throughout this disclosure as the float, for loading a tanker which is referred to throughout this disclosure as the offtaker.
  • a system constructed and arranged according to the present invention includes a rack for storing, retracting and paying out the large bore, stiff, floating hose used in the transfer of the liquid cargo between the float and the offtaker to achieve high transfer rates. Suitable means for mooring the offtaker and a manifold for connectingthe cargo hose at each end are also provided.
  • the float has associated therewith the rack, which in one embodiment of the invention is adapted to be raised and lowered by means of a hoist also located on the float.
  • Another embodiment comprises constructing the rack internal to the float.
  • the rack provides a means whereby the large bore, stiff hose can be stored, which will usually be necessary during severe sea conditions.
  • the rack is provided with a plurality of rollers.
  • the outboard end of the rack is constructed so that it prevents the hose from being bent or curved beyond its minimum bend radius.
  • the mooring of the offtaker and connection of the hose can be accomplished by a variety of means.
  • one such means might include the use of a helicopter which can deliver a messenger line to the offtaker which then can take in on the mooring line which is connected to the messenger line.
  • a line attached to the hose can be delivered to the offtaker by a line-throwing gun whereupon the offtaker can pull out the hose and attach it to its manifold.
  • a further object of the present invention is to provide a cargo transfer system between a float and an offtaker, which is economical and capable of operating in relatively severe environments.
  • Still yet a further object of the present invention is to provide a tandem moored float and offtaker with means for safely stowing the cargo transfer system during very severe environments.
  • the present invention comprises the combinations and arrangments as illustrated in the presently preferred embodiments of this invention, which is hereinafter set forth in such detail as to enable those skilled in the art readily to understand the function, operation, construction and advantages of it when read in conjunction with theaccompanying drawings.
  • FIG. I discloses a schematic elevation view of a cargo transfer system for tandem moored vessels in accordance with the present invention
  • FIG. 2 illustrates a top plan view of the system of FIG. 1;
  • FIG. 3 illustrates a perspective view of the outboard end of a rack constructed in accordance with the present invention
  • FIG. 4 illustrates an alternate embodiment of the cargo transfer system wherein a pivotally movable rack is employed
  • FIG. 5 illustrates a schematic side elevation view of the embodiment of FIG. 4.
  • FIG. 1 wherein the float or permanently moored storage unit 10 comprises a tanker moored in tandem with a shuttle tanker or offtaker 24.
  • the rack is located at the stern of the float l and includes an outboard end 16 provided with a downward and thence outboard extending curvature.
  • the terminal portion of the rack end 16 is designed to be I substantially parallel with the water surface 18. This configuration of the outboard end of the rack prevents the hose from being bent or curved beyond its minimum bend radius.
  • the rack 12 along its entire length is provided with a plurality of rollers 22.
  • the hose 14 is shown in its extended position connected to the shuttle tanker or offtaker 24. The hose extends from the stern of the float l0 and can be connected to the offtaker 24 by any one of the several means previously discussed.
  • the hose is connected to a manifold schematically illustrated as 26 on the offtaker.
  • the manifold 26 preferably is located as near as possible to the bow of the offtaker. For instance bylocating the manifold at approximately the point where the parallel sides of the offtaker 24 begin, any movement of the hose due to pitch is substantially reduced.
  • the float end of the hose 14 also is connected to a manifold (not shown) which may be located similar to the location manifold 26 on the offtaker, relative to the parallel sides of the float 10.
  • the rack 12 is provided with a movable end portion 28 which pivots about a forward point designated 30 located at the terminal end of the stationary portion 31 of the rack.
  • the entire rack, including the outboard end 28, is disposed laterally or outboard of one of the parallel sides of the float 10.
  • the free end of the movable portion 28 is connected to suitable means such as a standard hoist 32 which enables this portion of the rack to be raised and lowered for storage in a safe position.
  • suitable means such as a standard hoist 32 which enables this portion of the rack to be raised and lowered for storage in a safe position.
  • the rack will be disposed in a substantially horizontal position.
  • the movable rack portion 28 is lowered to the position shown in FIG.
  • a cargo transfer system for floating vessels comprising in combination, a first permanently moored cargo storage member and a second vessel moored in tandem with said first moored member, said first member and said second vessel being located offshore, longitudinal extending rack means generally parallel with the water surface operably connected with said first member for the storage, retraction and paying out of a cargo transfer hose adapted to be connected between said first member and said second vessel, said rack means including an end portion constructed and arranged to prevent said hose from being bent beyond its minimum permissible bend radiuswhen said hose is in its paid-out position, said rack means also including means for facilitating movement of said hose, and manifold means associated with said first member and said second vessel for connecting the ends of said hose thereto.
  • a cargo transfer system according to claim 1 wherein said means for facilitating movement of said hose comprises a plurality of rollers disposed for substantially the length of said rack means.
  • a cargo transfer system according to claim 1 wherein said first moored cargo storage member comprises a vessel having a configuration generally like that of said second vessel.
  • a cargo transfer system according to claim 1' wherein said end portion of said rack means is disposed proximate the stern of said first member.
  • a cargo transfer system comprising a downwardly curved portion terminating in substantially horizontal disposition at the operating waterline of said first member.
  • a cargo transfer system according to claim 1 wherein said end portion of said rack means comprises a pivotally movable member adapted to be raised and lowered.
  • a cargo transfer system according to claim 6 wherein said end portion of said rack means is disposed lengthwise and outboard of a parallel side of said first member.
