Definitions

  • the invention relates to a method for converting a single-hull tanker into a double-hull tanker, and a tanker formed by this method.
  • the hull of a ship is formed by the outer skin and this forms also the ship shape and especially the hull shape.
  • This shell serves frames, Bodenwrangen and bulkhead.
  • the most important stiffening elements are the frames, which can be arranged transversely and / or fore and aft. Accordingly, one speaks then of transverse bulkhead design or Lekssspantbauweise.
  • the ribs are arranged at intervals of, for example, 500 to 600 mm distance transverse or fore and aft.
  • the advantage of the Lekssspantbauweise is that steel weight can be saved.
  • frame frames are arranged at intervals of 2.5 to 3m.
  • the frame frames are formed by much stronger steel beams.
  • the outer walls of the ship and the tank walls are separated laterally and in the ground by intermediate spaces.
  • the clear minimum distance between the walls and the floor is precisely prescribed and serves to preserve the tank walls and floors as undamaged as possible in the case of accidents (collisions, ground contact) that damage the bottom of the ship or the outer skin. Environmental damage can be avoided as much as possible.
  • the method according to the invention avoids all the above-mentioned disadvantages and enables the cost-effective and rapid conversion of existing, even slim single-hull tankers into a double-hull tanker.
  • the present invention is based on the recognition that the desired double hull is needed only in the area of the tanks and that the double hull can also be produced by forming the second new hull at a distance around the existing first outer hull of a ship.
  • the novelty of the procedure is that around the existing ship in the tank area a new ship is built around.
  • the previous outer wall of the ship subsequently represents the tank wall and the bottom of the ship becomes the tank bottom.
  • the new outer wall and the new floor of the ship are being built.
  • the new tanks were used in the existing ship after the previous conversion methods.
  • the outer wall and the bottom of the ship remain the same. Only the tank walls and the tank bottoms were newly installed.
  • FIG. 1 shows from top to bottom the four consecutive process steps.
  • Fig. 2 is the top view of the deck of a converted ship.
  • 3 and 4 show two different cross sections through the finished ship in the double hull section, namely FIG. 3 along a frame frame and FIG. 4 along a normal frame.
  • FIG. 1a shows the schematic side view of a single-hull tank ship 1.
  • the hull comprises the stern section 2, the tank section 3 and the bow section 4.
  • the tank section 3 comprises twelve tanks 14, which are formed by seven transverse bulkheads and a continuous central longitudinal bulkhead and each have a transverse cofferdam at the ends of this section. The tanks are used to transport liquid petroleum products.
  • the tank section 3 may also consist of a plurality of separate tank sections arranged one behind the other.
  • the tank section 3 is separated along the dividing lines 5 from the stern section 2 and bow section 4, as shown in the illustration b). Subsequently, the tank section 3 is raised, as indicated by the arrow 6 in b).
  • the first fuselage shell 7 is rebuilt at a distance 9 with a second fuselage shell 8.
  • the distance 9 is prescribed by law as the minimum distance for double-hull tankers.
  • the tank internals and structures such as the tank lines 15 and all associated equipment must not be dismantled, but are simply lifted with the existing tank section 3 and used unchanged.
  • the new second hull 8 now forms the new bottom 10 of the ship.
  • a transition section 12 is preferably used in the tank section 3 towards the rear section.
  • the transition section 12 serves to compensate for the widening and thickening of the hull caused by the second sheath 8, resulting in a sliding transition to the old tail section 2.
  • the previous ship deck 16 can remain essentially unchanged.
  • the broadening of the ship's hull is covered by the additional cover strip 17.
  • the transition section 12 serves inter alia to streamline the widened hull to the old hull of the stern section 2. The same happens at the bow section 4 through the transitions 18, which are also shown in Fig. 1d.
  • FIG. 3 shows a cross section through the double-hull tanker produced according to the invention along a massive frame chippings both in the old hull and in the new double hull.
  • the old termespant 19 includes in a known manner, the old floor 21, the rising frame frames 22, the breech plates 23 and the deck beams 24 of the old ship's hull.
  • the ship's longitudinal center plane sits the longitudinal central bulkhead 25, whereby the ship stiffened and the tanks are each divided into two in length.
  • new second hull envelope 8 is built around the old hull envelope 7.
  • new frame ribs 20 are also provided here, which has uprising for the stiffening of the side wall of the ship frame frames 26, at their upper ends short beams 27 are fixed, which are so strong that the old inner hull are held with all the structures can.
  • the joists 27 serve to receive the new cover strip 17, about the double width of which the entire ship is wider.
  • the longitudinal center partition 25 is supported along the entire length of the tank section by the central web 28.
  • FIG 4 shows a cross section through the tank section of the new ship in the region of a normal frame.
  • a free space 29 which is also accessible depending on the dimension and the inspection and maintenance of the Tank walls that are identical to the earlier first hull shells 7 is used.
  • the new hull envelope 8 comprises transverse frames 30 and longitudinal frames 31.
  • Corresponding knee plates 32 are used for stiffening.
  • connection of the existing ship with the new parts takes place in terms of strength on the welding of the new cover strip at the level of the existing deck, on the central longitudinal beams in the new floor and on the frame part located in the new part.
  • the new parts can be prepared as area sections, or the extension piece as room section.
  • Area sections are the partially welded together steel plates of the floor, the side walls and the deck on which the stiffening elements have already been welded.
  • the 3m long intermediate piece is completely finished as a room section.
  • the central nave is then raised hydraulically by the height necessary for the raised floor.
  • the assembly of the floor panels is started, to do so, the ship must be continuously implemented on the car in order to assemble all floor panels can.
  • the next step is the welding of the additional deck plates at the height of the existing deck. Then the side plates are welded.
  • the chill panels 33 are mounted, which are the curved panels between the vertical side walls and the horizontal floor, and which are larger in size than the floor and side panels.
  • the old foredeck is welded and connected with cover plates streamlined to the centerpiece.
  • the value of 95% refers to the requirement that - depending on the load - the cargo tanks may only be filled up to a certain limit - for gasoline 95%.
