Definitions

  • SHEET 1 BF 2 F-BL L Inventor: Jon Arie Smir BY M WWQU JQ LV Aw ATTORNEYS PATENTED 555231971 35651329
  • the hulls of deep sea vessels of the prior art customarily end abruptly at the stern in a sternpost at which a drive screw is located. This shape is entirely suitable when the ship has a draft which is relatively deep compared to, its beam.
  • FIG. 2 is a plan sectional view on the line lI-II of FIG. I, the profile of the ship above the section beingshown in dot-dash lines; and 2 FIG. 3 is a body plan of the after body of the ship of FIGS. 1 and 2.
  • FIGS. 1 and 2 there is shown the stem 1 of a ship according to the invention, having bulges 2 in which the beds or baseplate frames 8 of main propulsion engines 3 have been schematically indicated.
  • the engines 3 are disposed with their crankshafts substantially parallel to the longitudinal dimension of the vessel.
  • the engines 3 are coupled by relatively short rearwardly extending drive shafts 4 to screws 5.
  • Two rudders 6 are provided.
  • the rudders 6 are disposed in the slipstreams from the screws, but displaced athwartships from the shafts so that upon overhaul the shafts 4 can be pulled out aft of the vessel without unshipping the rudders.
  • FIGS. 1 and 3 indicate, the floor of the hull rises smoothly between the two bulges 2. See the profile at the centerline indicated by the line 7 in FIG. 1.
  • FIG. 3 The cross sections of the after body are shown in FIG. 3 at the various equally spaced stations 1, /ia, is, A; A A. 0 and at the further stations A, B and C all indicated in FIG. 2.
  • the full-load-waterline is indicated by the letters LWL.
  • the beam amounts, in the case illustrated, to more than 2.4 times the draft, which value is approximately the lower limit of that ratio for advantageous construction in accordance with the invention.
  • the invention makes possible a very short or bluff shape for the stem with good usage of the space at the stern of the vessel for cargo holds, and simultaneously provides low water resistance and good streaming characteristics around and past the screws.
  • the invention itpropulsion engine, and a piston-type main propulsion engine resting on each such bed, said bulges being open to the interior of the hull above said engines.
