Definitions

  • ABSTRACT Primary Examiner-Trygve M. Blix Attorney-Chittick, Pfund, Birch, Samuels & Gauthier [5 7 ABSTRACT A horizontal bank of structurally tied, horizontally extending, usually submerged storage cylinders. An above water, horizontal wing structure fitted for berthing ships alongside. A plurality of rows of vertical struts joining the cylinder bank and wing structure, and providing therebetween slips for docking barges. Means for cargo storage and transfer. Provision for ballasting of the struts and storage cylinders. Support facilities for the berthed ships.
  • This invention relates to the new. field of deep water ship berths and piers adapted to be located closer to the main ocean trade routes, and to be connected to inland transportation systems by pipelines, causeways, barges, conveyors or other interface vehicle or device.
  • the prior devices known to applicant as purportedly for the new field here concerned include monomoors anchored to the sea bottom and connected to the shore or to other monomoors by flexible submarine pipelines. These monomoors are normally anchored rigidly in position and have the disadvantage of potential casualties to and short life time of flexible hose connection to the off loading ship and/or the loading tank farm or monomoor.
  • the prior apparatus has further included articical islands constructed on shoals, with piers of pilings or concrete blocks. Also, steel islands such as Texas Tower structures have been sought to be adapted to the deep water terminal purpose.
  • the invention apparatus comprises a floating island structure or deep water ship terminal which is less costly and more flexible and adaptable than those hereinbefore described, and which can be anchored or free floating in a convenient location.
  • the invention structure provides a safe berth for tankers, bulk carriers, or any type of ship, and with built-in floating storage and off loading as well as loading facilities for the transfer of cargo from ship to ship, from ship to barge, and from ship to pipeline.
  • the floating terminal hereof is self positioning, and adapted to be relocated depending upon the draft requirements, the geographical considerations, or seasonal variation in wind, current, and waves.
  • the terminal also is fittable with any hydraulic or other effective fendering system assuring safe berthing of large ships alongside, and assuring also a reduction in impact loading.
  • the invention terminal novelly affords self-contained ferry type slips for the safe berthing of barges therewithin, and with freedom of relative vertical motion.
  • the floating terminal hereof further has means for varying its draft, as well as its beam, length and depth, and independently the relation between its water plane area and displacement.
  • the invention terminal provides still further a platform of practically zero vertical motion in any degree of freedom, and with stability maintained effectively for wide ranges of change in the valuation of the foregoing parameters.

  • the floating platform or wing assembly 10 hereof is variously fitted for its several floating terminal capabilities, and which may include cargo handling, and helicopter landing, as well as the mentioned berthing of ships S and barges B, FIGS. 1, 4, and 8. And for the berthing purpose the terminal hereof is provided, within the wing 10 and/or otherwise, with all support facilities for a moored ship, from bunkers, fresh water, to reefer, and also general stores.
  • the platform 10 For the berthing or docking of ships the platform 10 is provided with an hydraulic or other fendering system arranged as conventionally, to assure safe berthing of one or more tankers or other ships alongside, and which may comprise a suitable number and disposition of constant tension mooring winches and lines 14, together with the usual roller or other bumpers 15.
  • an hydraulic or other fendering system arranged as conventionally, to assure safe berthing of one or more tankers or other ships alongside, and which may comprise a suitable number and disposition of constant tension mooring winches and lines 14, together with the usual roller or other bumpers 15.
  • the platform By its accommodating one or more helicopter or STOL ports or landing areas 16, FIG. 1, the platform is afforded the efficient supply of relief crews, and performance as well of other exchanges or communications by air.
  • the novel terminal hereof is fitted more particularly with means for transfer of solid or liquid cargo or ballast between moored or berthed ships and/or barges, or between ship or barge and terminal, or between terminal and shore.
  • the service facilities will typically include cranes and loading arms as may be conventional, and are therefore schematically shown at 16,17, FIG. 1.
  • the invention terminal further comprises a network or lengthwise-beamwise array, and more particularly two or more parallel, lengthwise rows, of vertical struts or cylinders 18, joined at their upper ends to the underside of the platform 10.

  • This invention novelly provides, in combination and connection with the platform 10 and struts 18, a number of usually submerged, watertight, horizontally disposed, terminal-stabilizing storage and/or ballast tanks, chambers or cylinders 21.
  • the storage-ballast chambers 21 comprise lengthwise projecting, uniformly proportioned cylinders, of substantially the length of the platform 10, provided with rounded end closures as shown, FIG. 3, and rigidly joined to and so as to form tees with the lower terminals of the slip enclosing struts 18, FIGS. 2 and 6.
  • the platform-length storage or ballast tanks or cylinders 21 are laterally joined and rigidified by trusses or the like 22, FIGS. 3 and 4, spanning between them at suitable intervals, which may include or coincide with the transverse planes of their intersection with the struts 18.
  • the invention terminal further comprises one or more series of shorter, smaller, storage-ballast cylinders 23, FIGS. 3 and 5, paralleling the cylinders 21 and ordered in closely spaced lateral banks spanned and strengthened by transverse overlying and underlying plate girders 24, 25 joined thereto and to cylinders 21, as shown, FIGS. 3 and 5.
  • the shorter cylinders 23 are herein shown to extend equally-oppositely of the longitudinal center of the terminal, over approximately half its length, and intermediate the barge slips.
  • the array of cylinders 21, 23 serves to substantially increase the storage capacity of the terminal, and more particularly is usable, in the case of some at least, for the storage of liquid cargo.
  • the terminal storage capacity comprises the struts 18 and also the wing structure 10, as well as cylinders 21, 23, all defining volumes usable for ballasting the terminal, as with water, and/or for storage of liquid or flowable cargo.
  • all cylindrical parts, and more particularly the struts l8 and cylinders 21,23, may be reinforced by ring and/or bulkhead type stiffeners 26, FIG. 6, that may define in the struts 18 and cylinders 21, 23, inner or double walls 27, FIGQ7, affording access trunks from the above water wing structure to the storage and/or ballast cylinders for ducts, pipes, conduits, and human access.
  • the described bulkheadweb or girder construction may enclose storage chambers 28, FIGS. 4 and 5, which chambers 28 are herein seen to parallel cylinders 21 and overlie struts 18, with which they may communicate.
  • the stable platform terminal hereof By its provision of extensive and flexible storage capacity, as just described, the stable platform terminal hereof, it will be appreciated, can be ballasted to achieve varying drafts to provide better sea and position keeping; improved adaptation to berthing of tankers, bulk carriers, and other ships and barges; and reduced motion response.
  • the stable platform terminal hereof is seen also to be distinguished by a quite small water plane area in relation to its displacement, this tending to negligible motion of the platform 10 even in severe weather.
  • the stable terminal hereof is uniquely characterized by greatly reduced and/or dampened vertical movement (heave, pitch, or roll) response to wave motion.
  • the platform terminal is made very stable in the longitudinal as well as transverse plane, and is accorded a low center of gravity in relation to its center of buoyancy, which permits large top loads to be placed on the deck.
