Definitions

  • PATENIE MAY 2 91973 SHEET u 0F 4 RIGID DISCONNECTABLE COUPLING FOR WATERBORNE VESSELS BACKGROUND OF THE INVENTION
  • the invention relates generally to waterborne or ocean push towing, and more especially to a novel type of push towing system providing at least two widely spaced point coupling of, or more particularly multiple, short, simultaneously engaged point supports for, said push towing system. 4
  • the transporting of a barge, or train of barges, by pushing it, is much to be preferred to, and has large advantages over, the pulling of the barge or train of barges, as with a steel cable.
  • the push tow integrated or thrust coupled tug-barge system, or self propelled tank barge, as utilized particularly for shipment of bulk or liquid cargoes, has far greater maneuverability than the pull tow arrangement, wherein the tow is a substantial distance or hawser length away from the tug. With the push tow, because the tug and barge are close coupled, the tow can be turned more quickly and through sharper angles, stopped and even reversed.
  • a principal object of this invention is to provide a push towing system or push tow unit, qualifying (for inspection and certification purposes) the propulsion and cargo units thereof for treatment as separate vessels as they are today.
  • the benefit or advantage is that a push towing tug and barge systemv,and particularly including that for safe disengagement in sea going operations, can be built for as little as 60% of the cost of a tanker of equivalent capacity.
  • This invention solves the foregoing problem, and provides a rigid type push tow system meeting prudent criteria for treatment of the tug and tow as separate units, and which, therefore, is demonstrably safe and practicable to operate under all expected conditions of sea and navigation.
  • the invention provides for the coupling together of waterborne or floating bodies, such as surface ships, submarines, tugs and barges or other vessels, in a rigid manner, that is, in a manner whereby relative motions between the coupled bodies or watercraft will not be possible.
  • the fixed coupling hereof also provides for a multitude of relative displacements of the vessels being joined, with the floating watercraft or vessels being rigidly joinable subject to and irrespective of different relative drafts or floating or ballasting conditions of the pushed and pushing vessels.
  • the pushed vessel has an open or throughgoing deep recess or stem notch, which may have any contour permitting the pushing vessel bow end to be fully inserted therein.
  • the coupling means or point supports are provided in multiple, or two or more, mating assemblies or groups located on each side, or on the front and sides, of the bow end and stern notch. At least one such group is arranged on the forward portion of the stern notch and bow end. At least one other such group is arranged on the aft portion of the stern notch and bow end, with the pushing vessel elements thereof located at about amidships.
  • the multiple coupling means or point supports hereof are also placed in such a way that said forward andaft portion groups thereof engage and disengage at exactly the same instant, in the closing and withdrawal of the vessels to and from their push tow relation.
  • the two vessels when engaging or disengaging, are always connected in at least two fore and aft locations, these being the aforementioned fronts or forward portion sides of the stern notch and bow end, and aft portion sides of the stern notch, and about amidships sides of the tug.
  • FIG. 1 is an assembly view in perspective of a push tow system of the invention
  • FIG. 2 shows a front end arrangement of the coupling means
  • FIG. 3 shows a latch and bar embodiment of one assembly of the coupling means
  • FIGS. 4A and 4B illustrate the capability of the invention coupling means for interengaging the push tow vessels in different embodiments and in different combinations of their relative displacement
  • FIG. 5 is a top plan view illustrating the simultaneous engaging and disengaging of the multiple coupling means or point supports of the invention
  • FIGS. 6A and 6B illustrate exemplary wear resistant and shock absorbing configurations of the invention coupling means
  • FIG. 7 is a top plan view of a push towing system of the invention incorporating fenders
  • FIG. 8 shows an exemplary tug-barge separating means of the invention

  • Barge 20 has a stern notch 2l which is deeply indenting and also throughgoing in the vertical direction, as shown.
  • the push or thrust imparting vessel 22 may within the invention be either a powerless carrying waterborne craft, as when the vessels form a train of rigidly coupled craft, or an independent powered waterborne craft, such as the tug shown.
  • Pushing vessel or tug 22 has a bow end 23 that penetrates and fits fully into the stern notch 21, that extending rearwardly, upon said full inserting, to amidships, or approximately so, of the tug 22.

  • the strength, or shear withstanding capability, of the invention coupling means is determined by the material selected therefor, and by their cross sectional areafThe shear withstanding, or vertical-thrust supporting, requirement of the coupling means is a function both of the displacement of the pushing vessel, or tug, and of the relative displacement of the pushing and pushed vessels, or tug and barge.

  • FIG. 68 showing the same with a greater horizontal, cross sectional dimension.
  • theconfiguration of the coupling means may limit their length, as when pins or other round elements are selected therefor.

  • the length, or effective fore and aft dimensioning, of the coupling means is made a small fraction of the fore and aft dimensioning of the stern notch, and not greater than that which permits the disengagement of the towing system vessels within the predicted or expected time interval or period of consecutive ship motions.
  • the coupling means hereof are predeterminedly formed with a quite short lengthwise or fore and aft dimension or proportion. In its effective or axial length, such dimension may be, for example, on the order of, or about, 4 feet.
  • the uncoupling is accomplished in as short as a 3-to-5-second, or even shorter, interval. It will be apparent that for this brief disengagement period the ships or tugs captain is enabled by the invention to chose an interval between the passage of successive waves, when he may separate free from travelling wave induced motions. This safe, controlled disengagement of the vessels obviously cannot be attained under open ocean or rough seas conditions, with the prior, continuous length type of rigid push tow coupling means.

  • the mentioned axial spacing of, or fore and aft distance between, the forward portion and aft portion coupling means may, and often does, correspond to about one half the length of the pushing or penetrating vessel, or tug.
  • the length of notch 21, and the spacing between the forward portion and aft portion coupling means will be approximately equal to, or will approach, the length from the bow to amidships of the pushing craft. Or the forward and aft portion coupling means spacing will approximate the pushing vessels bow to amidships length less the distance that the forward portion coupling means may belocated aft of the pushing vessel's bow.
  • the shear load (of 1150 long tons) produced by the weight of the tug may be increased or added to by the dynamic action between the two interlocked vessels, as would originate mainly from the pitching and rolling of the system.
  • the load imposed by the tug upon the barge (and vice versa) could increase,then, in the given example, to as much as about 1500 long tons.
  • This resultant coupling shear load can be considered as acting at the center of gravity of the tug, and is indicated by the arrow L, FIG. 10A.
  • the forward supports will take a load of F 2/54 1500 55.6 long tons, FIG. 9A.
