Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ships, and particularly relates to a stern structure of a ro-ro passenger ship with a stern ramp and a side stern ramp. Background Art
[0002] To improve the adaptability to docks and the loading and unloading efficiency, some ro-ro passenger ships are provided with a stern ramp and a side stern ramp at the stern as channels connecting the dock and the cargo hold. In addition, equipment such as an escape hatch for the steering gear compartment and mooring equipment need to be arranged at the stern of the ro-ro passenger ship, and the layout space is very tight. In order to make room for the layout of relevant equipment, the conventional method is to move the side stern ramp forward as much as possible to strive for more space at the stern for arranging the escape hatch of the steering gear compartment and mooring equipment. However, moving the side stern ramp forward will inevitably occupy the space of the cargo hold, resulting in a decrease in the ship's loading capacity.
[0003] There are two independent steering gear compartments, left and right, at the stern of the ro-ro passenger ship. Escape hatches are respectively arranged, and small hatch covers are arranged on the open deck. In addition, mooring equipment also needs to be arranged on the open deck at the stern.
[0004] As Figure 1 shown, the stern ramp 53 is arranged at the stern, the side stern ramp 54 is arranged on the starboard side of the stern, and the left steering gear compartment escape hatch 51 and the right steering gear compartment escape hatch 52 are respectively arranged on both sides of the stern ramp.
[0005] In order to make room for the mooring equipment at the stern and the small hatch cover of the right steering gear compartment escape hatch, and at the same time to ensure that the side stern ramp does not exceed the maximum ship width in the stowed state, the side stern ramp needs to be arranged as far forward as possible, occupying a relatively large amount of space in the cargo hold 50.
[0006] In the existing layout method, in order to strive for more space for arranging the escape hatch of the steering gear compartment and mooring equipment, the side stern ramp needs to be moved forward, which will inevitably occupy more cargo hold space, resulting in a decrease in the ship's loading capacity. Summary of the Utility Model
[0007] The technical problem to be solved by the utility model is to overcome the above-mentioned defects existing in the prior art and provide a stern structure of a ro-ro passenger ship with a stern ramp and a side stern ramp.

[0024] Next, a preferred embodiment is given and the present utility model will be described more clearly and completely in conjunction with the accompanying drawings.
[0025] As Figure 2 , Figure 3 and Figure 4 shown, a tail structure of a ro-ro passenger ship with a stern ramp and a side stern ramp includes a left rudder engine room 11 and a right rudder engine room 21 provided at the tail of the ship; the deck above the left rudder engine room 11 and the right rudder engine room 21 is provided with a stern ramp 30, a side stern ramp 31, a left rudder engine room escape opening 12 and a right rudder engine room escape opening 22.
[0026] The left rudder engine room escape opening 12 communicates with the left rudder engine room 11, and the right rudder engine room escape opening 22 communicates with the right rudder engine room 21.
[0027] The side stern ramp 31 is provided on the right side of the stern ramp 30.
[0028] Both the left rudder engine room escape opening 12 and the right rudder engine room escape opening 22 are provided on the left side of the stern ramp 30.
[0029] The left rudder engine room escape opening 12 and the right rudder engine room escape opening 22 are arranged side by side along the ship width direction. The left rudder engine room escape opening 12 is provided on the left side of the right rudder engine room escape opening 22.
[0030] There is an escape passage 40 from the right rudder engine room 21 to the right rudder engine room escape opening 22 at the rear side of the left rudder engine room 11.
[0031] There is a partition bulkhead 41 at the rear side of the left rudder engine room 11, and an escape passage 40 from the right rudder engine room 21 to the right rudder engine room escape opening 22 is formed between the partition bulkhead 41 and the hull tail bulkhead 42.
[0032] The connection between the left rudder engine room escape opening 12 and the left rudder engine room 11 is located on the left side of the escape passage 40.
[0033] Both the left rudder engine room escape opening 12 and the right rudder engine room escape opening 22 are vertically distributed. Both the left rudder engine room escape opening 12 and the right rudder engine room escape opening 22 extend upward to the open deck 50.
[0034] Both the left steering engine room escape opening 12 and the right steering engine room escape opening 22 are provided with hatch covers 51 on the open deck.
[0035] In the prior art, since both the aft side ramp and the right steering engine room escape opening are arranged on the starboard side, the layout space on the starboard side is particularly tense, while the left steering engine room escape opening is arranged on the port side, and the space on the port side is relatively more abundant. As Figure 1 shown, the aft side ramp occupies a relatively large amount of cargo hold space, and the distance H1 from the hull aft bulkhead to the end of the aft side ramp is 9762 mm.
[0036] In this technical solution, the existing space is utilized more reasonably. The right steering engine room escape opening is moved to the port side, and a part of the space is demarcated at the rear of the left steering engine room as the escape passage from the right steering engine room to the right steering engine room escape opening. At the same time, the hatch cover of the right steering engine room escape opening arranged on the open deck in the prior art is also moved to the port side.
[0037] In this way, the requirement for the layout space on the starboard side is reduced, and the aft side ramp can be appropriately moved backward. As Figure 3 shown, in an example, the distance H2 from the hull aft bulkhead to the end of the aft side ramp is 8500 mm. In this way, more space can be vacated for the cargo hold 10, increasing the cargo hold volume and loading capacity of the ship.
[0038] In addition, the layout of the open deck is also more compact, creating more space for the layout of other equipment on the ship.
[0039] The utility model reasonably plans the positions of the steering engine room escape openings and mooring equipment, optimizes the position of the aft side ramp, not only ensures the layout space of various equipment, but also can reduce the space occupied by the aft side ramp in the cargo hold, maximizing the loading capacity of the ship.
[0040] Although the specific implementation manners of the utility model have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the appended claims. Without departing from the principle and essence of the utility model, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the utility model.
