Definitions

  • the invention relates to a ship with a superstructure or the like.
  • receiving torso body on the underside of which at least two are spaced apart
  • Support over at least part of the fuselage body essentially in the direction of travel of the ship which are each on at least one in the essentially in the direction of travel of the ship over at least part of the hull body extending buoyancy seat, with at least a part at least a support with its upper end on the side wall of the fuselage body ends, with its lower end on the associated buoyancy body essentially centered and / or essentially radial to a propeller drive shaft
  • Propeller propulsion device provided attached and together is arranged with the associated buoyancy body in such a way that at least one part this buoyancy body within that spanned by the side wall of the fuselage body Plane or the outer contour of the ship.
  • SWATH Small Waterplane Area Twin Hull stands.
  • floats which are generally elongated like a cigar own and are below the water surface, during which the Superstructures or the like receiving body of the body attached to the buoyancy body Support is worn and is above the water surface.
  • two spaced-apart, parallel are usually parallel elongated to each other and directed in the direction of travel of the ship Buoyancy bodies are provided, which are arranged symmetrically to the central axis of the ship.
  • the drive is also regularly contained in the buoyancy bodies is led out of the rear of the respective buoyancy body and the Propeller carries.
  • a drive is usually provided in each buoyancy body.
  • the supports supporting the fuselage can extend essentially over the entire Extend length of buoyancy body; alternatively, they can also be interrupted his or several successive supports attached to the buoyancy bodies his.
  • the characteristic of the SWATH construction is that the buoyancy of the ship is mainly generated by the buoyancy bodies under water and the displacement change in the area of the waterline is only slight during the hull bodies supported by the supports so far above the water surface hovers that he is essentially not touched by the swell. That’s it possible that the journey of such a ship through the water and thus its swimming position remains essentially unaffected by the swell.
  • the height of the supports to the in wave area in question is adjusted accordingly.
  • the floats can be partially flooded and also serve as Ballast tanks, regardless of the loading condition of the ship Floating position and thus its draft essentially constant hold so that the previously described effect regardless of the loading condition can be used.
  • the supports were vertical arranged and at the bottom of the fuselage body at a distance from it Fixed side wall offset inwards.
  • the supports are inclined outwards or spread and thus protrude on both sides over the side wall of the fuselage body addition, so that the distance of the buoyancy bodies from each other is greater than the maximum Is the width of the fuselage body and the buoyancy body under water each outside the outer contour created by the side wall of the fuselage body are located.
  • JP 56-82687 A proposed a construction at which the supports with their upper end on the side wall of the fuselage body ends, with their lower end on the associated buoyancy body essentially are attached centrally or radially to the cylindrical buoyancy body, between their rectilinear upper end and lower end run in such a way inside are inclined so that they are within the from the side wall of the fuselage body stretched level or the outer contour of the ship.
  • JP 56-108367 A describes a ship in which the supports with the Side wall are aligned and directed vertically, the buoyancy bodies being such are arranged off-center at the lower end of the supports that they are within the plane or the outer contour spanned by the side wall of the fuselage body of the ship.
  • the invention proposes that at the beginning of a ship mentioned type at least a part of at least one support in at least one on First section of the fuselage body and one on the associated buoyancy body ending second section, of which the first section is either (a) essentially flush with the side wall of the fuselage body or vertically runs or (b) towards the center wall of the hull body is inclined and the second section relative to the first section towards the middle of the ship is offset and / or inclined.
  • the supports are angled in themselves and thus form the 'Knuckle' towards the middle of the ship.
  • this construction is particularly easy to lay on a quay wall or Sheet pile and / or on other ships.
  • This is according to the invention achieved that the supports in a first section and a second section are divided, of which the first section ends at the trunk body and either (a) essentially flush with the side wall of the fuselage body or vertically runs or (b) towards the center wall of the hull body is inclined, although the angle of inclination with respect to the vertical is smaller is the angle of inclination of the adjoining second section.
  • This Wise is an annoying recess between the drop side and the supports avoided.
  • the ship can not only on its side wall, but also optionally or additionally on the upper first section of the support without any problems be fendered using the same fenders.
  • the supports with their lower second section stronger are kinked, it is still guaranteed that the buoyancy are inside the outer contour of the ship and therefore none for mooring form disturbing underwater obstacles.
  • With the help of angled supports still a good propulsion performance of the Propeller drive device achieved because the supports with the lower end of their more angled or kinked lower second section on the associated Buoyancy body - hydrodynamically favorable - essentially central or arranged symmetrically and / or substantially radially to the propeller drive shaft are.
  • a preferred embodiment for is particularly advantageous for secure application which is the first section of the pillars at least approximately to the waterline extends.
  • the second section should be on Connect the first section directly.
  • the buoyancy body is cross-section to one in essential plane of symmetry spanned in the direction of travel of the ship essentially symmetrical, in the event that the buoyancy body with a Propeller drive device is provided, the propeller drive shaft preferably lies in the plane of symmetry.
  • the associated support with its lower end essentially extend in the plane of symmetry to be symmetrical for a good propulsion To achieve flow.
  • the associated Support with its lower end arranged substantially radially on the buoyancy body.
  • a currently particularly preferred specific further development of this embodiment is characterized by a pair of first supports and a pair of second ones Columns, of which the first columns are arranged substantially vertically and the second supports are formed according to the previously explained invention, wherein preferably the two pairs of supports one behind the other in the direction of travel of the ship and / or the supports of each pair symmetrical to the central axis of the ship are arranged and / or the distance between the first supports not equal to that The distance between the second supports is.
  • this training are accordingly two pairs of supports are provided, of which the two supports of the one pair in conventionally arranged vertically and opposite the side wall of the fuselage body are arranged offset inwards, while the two supports of the another pair are designed according to the invention as 'articulated legs'.
  • each buoyancy body is a conventionally designed support as well as one supports designed according to the invention.
  • FIG. 1 and 2 the basic structure of a SWATH ship is illustrated in FIG. 1 and 2, in which, as a comparative example, a ship with a conventional SWATH construction is shown, which has so far been used with preference has been.
  • the SWATH ship is shown in Figure 1 so that the Shows the bow towards the viewer.
  • the SWATH construction shown has two elongated, cigar-shaped floats 2, 4, which are parallel to each other and at a distance from each other as well arranged symmetrically to the central axis of the ship, not shown in the figures are.
  • the buoyancy bodies 2, 4 in illustrated embodiment a circular cross section and thus in essentially the shape of a cylinder.
  • the two buoyancy bodies 2, 4 extend themselves in the direction of travel of the ship and included not shown in the figures Drive devices. These drive devices each drive a drive shaft 20, which emerge at the rear end or at the rear of the buoyancy bodies 2, 4 and each carry a propeller 22; of course the run Drive shafts 20 also in the direction of travel of the ship.
