Definitions

• the invention relates to a convertible cargo ship with a large degree of deck opening, the hatch openings of which can be opened and closed with cross hatch covers, and with crossbars arranged between the hatch openings and extending over the weather deck, preferably from board to board.
• sheet be convertible by the loading space, namely from a ship with a normal side height to a ship with a high side height and thus offer the possibility of alternating loading variants and a reduced measurement in comparison to other high-sided ships.
• this object is achieved in that the hatch covers which open in the transept direction together with the outer walls (longitudinal walls) of the crossbars which are between the holds and which extend beyond the level of the weather deck form an upward-extending outer ship boundary (outer skin) in the vertical opening position, so that at open hatch covers a ship with a larger side height or hatchless ship is created because the opened hatch covers have taken on the protective function of the outer skin.
• the ship can be driven with some open and some closed hatches.
• the upward-facing end faces of the opened hatch covers and the upper deck of the crossbars preferably form one level and, if necessary, allow the installation of light rain covers.
• running rails are arranged on the end faces mentioned.
• the end faces are part of a box girder that delimits the hatch covers.
• the hatch cover is preferably given an L-shaped cross section by the box girder.
• One leg can either protrude upwards and / or downwards over a hatch cover side.
• the top of the hatch covers in the closed position which corresponds to the outside of the ship in the open position, forms a vertical surface with the rest of the outer skin and with the outside of the crossbars.
• the outer surfaces can also be offset from one another.
• the outer skin and the overlying outer side of the crossbars can be arranged in a vertical plane and the outer side of the opened hatch covers can be offset inwards, thereby creating an operational aisle on the side.
• the crossbars have vertical sealing edges, to which known seals are attached, against which the hatch cover with a suitable sealing profile
• locking elements are arranged in the cross bolt, with the aid of which a non-positive, watertight and secure formwork of the hatch covers can be installed.
• Another seal is located on the weather deck reinforced as hatch fill, on which the hatch covers are hingedly attached near the side of the board, so that water resistance can also be guaranteed here.
• the drive, opening and closing, the hatch cover is either hydraulic - using a working cylinder - or using a cable.
• the already mentioned disadvantage of long crane games when loading and unloading high-sided ships is countered according to the invention in that the hatch covers in the closed position in the region of their abutting end faces (box girders) can be connected in an articulated manner on the underside of the hatch cover, whereby a pair of hatch cover folds is formed, which is required can be erected either on the starboard side or on the starboard side, which opens the hatch and on the one facing the quay
• the hatch covers When loading the lower hold of the ship, the hatch covers can first be stowed as a folding cover on the side of the ship away from the quay, in order to achieve short transport routes for loading. Then the hatch covers are closed, their hinge connections are released, the hinge and drive connections of the hatch cover on the weather deck are restored so that both hatch covers can be opened again to the outside or raised and to continue loading the upper cargo area. The same procedure can be followed when unloading the ship.

• Fig. 7 Cross section of the ship with hatch covers folded on one side
• Fig. 1 shows the basic principle of the invention, which is why disturbing details have been omitted.
• crossbars 3 are built above the weather deck 6 between the hatch openings at a distance that determines the length of the loading space. They contain the bulkheads 5 and at the same time serve as a guide and stop element for the hatch covers 2a, 2b.
• the hatch covers 2a, 2b are transverse and are hinged 7 to the weather deck 6 of the hull 1.
• FIG. 1 shows 3 positions of the hatch cover at the same time:
• Fig. 2 shows that in position A a seal of the lower cargo space is created by the closed hatch cover 2a, so that the measurement values are only calculated up to the height of the weather deck 6.
• Fig. 3 shows that in position B the cargo space is enlarged up to the upper edge of the transverse deck strip 3 (crossbars) and the hatch covers 2b are sealed in the extension of the outer skin with an offset inwards on the crossbars 3.
• the measurement values are calculated up to the upper edge of the transverse deck strip 3.
• FIG. 4 shows the articulation of the hatch cover 2, the seal 10a, 10b and the drive.
• the drive shown here by means of hydraulic cylinder 9
• the hatch cover 2a, 2b can be brought from position A to position B.
• position A a seal against ingress of sea water is achieved via the deck seal 10a to the double casing 8.
• the deck seal 10b again seals against incoming sea water.
• a seal is achieved perpendicular to the hatch cover edges by the hatch cover 2 b striking against the outer seal 11, which is arranged on the crossbar 3.
• FIG 5 shows the interlocking of the hatch cover 2b, which is set up vertically, with the transverse deck strip (crossbar) 3 by means of latches 13, which are arranged several times over the height and connected to one another via a push rod 19. These latches 13 are opened in FIG the locking pockets 12 are retracted into the crossbar 3 and press the cover 2b against the outer seal 11. These latches 13 thus take over the transmission of the forces which arise from the internal charge pressure and also from the external sea impact result and are adapted to these functions in their dimensioning and execution.
• Fig. 5 shows the seal 17, 18 between the two hatch covers 2a in position A and the articulation by means of folding hinges 14 and tie bolts 15 to form a pair of folds.
• the rails 26 can be seen for a light rain cover when hatch covers 2b are raised.
• This figure also shows the principle of the pair of lid folds which is stowed on the right-hand side of the ship when the hatch is open.
• Both hatch cover halves 2 are provided with several hinges 14 under the hatch cover longitudinal members 4. Depending on the type of hatch opening, it is possible to provide these hinges 14 with and without draw bolts 15. The bolts 15 can be inserted or pulled into the hinges 14 by means of a mechanical operation, not shown. At the same time, the hinge bolts of the cover hinges 7 and the working cylinders 9 (FIG. 4) must be released from the hatch cover 2a.
• the guide wheels 20 then ensure that the lid to be pulled runs in parallel until the folding process is completed. After opening the hatch there is the possibility of loading / unloading the hold either from Bb or Stb over the lower side height of ship 1.
