Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a stern structure of a ro-ro passenger ship with a stern ramp and a stern side ramp. Background Art

[0002] In order to improve the adaptability of the terminal and the efficiency of loading and unloading, some ro-ro passenger ships will be equipped with both a stern ramp and a stern side ramp at the stern as a passage connecting the terminal and the cargo hold. In addition, the stern of the ro-ro passenger ship also needs to be equipped with equipment such as the steering engine room escape and mooring equipment, and the layout space is very tight. In order to leave space for the layout of related equipment, the conventional practice is to move the stern side ramp forward as much as possible, and strive for more space at the stern for arranging the steering engine room escape and mooring equipment. However, moving the stern side 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 rooms on the left and right at the rear of the ro-pax ferry, each with an escape hatch and a small hatch cover on the open deck. In addition, mooring equipment is also required on the rear open deck.

[0004] like Figure 1 As shown, the tail ramp 53 is arranged at the tail, the tail side ramp 54 is arranged at the starboard side of the tail, and the left steering engine room escape 51 and the right steering engine room escape 52 are respectively arranged on both sides of the tail ramp.

[0005] In order to make room for the mooring equipment at the rear and the small hatch cover of the right rudder engine room escape, and also to ensure that the rear ramp does not exceed the maximum ship width when stored, the rear ramp needs to be arranged as forward as possible, occupying more cargo hold space of 50.

[0006] In the existing arrangement method, in order to gain more space for arranging the steering gear compartment escape and mooring equipment, the rear 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 invention

[0007] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide a stern structure of a ro-ro passenger ship with a stern ramp and a stern side ramp.

[0008] The present invention solves the above technical problems through the following technical solutions:

[0024] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, a stern structure of a ro-ro passenger ship with a stern ramp and a stern side ramp comprises a left rudder engine room 11 and a right rudder engine room 21 arranged at the stern of the ship; a stern ramp 30, a stern side ramp 31, a left rudder engine room escape 12 and a right rudder engine room escape 22 are provided on the deck above the left rudder engine room 11 and the right rudder engine room 21.

[0026] The left rudder engine room escape 12 is connected to the left rudder engine room 11 , and the right rudder engine room escape 22 is connected to the right rudder engine room 21 .

[0027] The tail springboard 31 is disposed on the right side of the tail springboard 30 .

[0028] The left rudder engine room escape opening 12 and the right rudder engine room escape opening 22 are both arranged on the left side of the tail ramp 30 .

[0029] The left steering engine room escape opening 12 and the right steering engine room escape opening 22 are arranged side by side along the ship width direction. The left steering engine room escape opening 12 is arranged on the left side of the right steering engine room escape opening 22.

[0030] An escape passage 40 from the right servo engine compartment 21 to the right servo engine compartment escape opening 22 is provided at the rear side of the left servo engine compartment 11 .

[0031] A partition wall 41 is provided 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 wall 41 and the stern bulkhead 42 of the hull.

[0032] The connection point between the left rudder engine room escape 12 and the left rudder engine room 11 is located on the left side of the escape passage 40 .

[0033] The left rudder engine room escape opening 12 and the right rudder engine room escape opening 22 are both vertically distributed. The left rudder engine room escape opening 12 and the right rudder engine room escape opening 22 both extend upward to the open deck 50.

[0034] The left rudder engine room escape opening 12 and the right rudder engine room escape opening 22 are both provided with hatch covers 51 on the open deck.

[0035] In the prior art, since the rear ramp and the right rudder engine room escape are both located on the starboard side, the layout space on the starboard side is particularly tight, while the left rudder engine room escape is located on the port side, and the port side space is relatively abundant. Figure 1As shown, the stern ramp occupies more cargo hold space, and the distance H1 from the stern bulkhead to the end of the stern ramp is 9762 mm.

[0036] In this technical solution, the existing space is utilized more reasonably, the right rudder engine room escape is moved to the port side, and a part of the space on the rear side of the left rudder engine room is marked out as an escape passage from the right rudder engine room to the right rudder engine room escape. At the same time, the hatch cover of the right rudder engine room escape located on the open deck in the prior art is also moved to the port side.

[0037] In this way, the space requirement on the starboard side is reduced, and the rear ramp can be moved back appropriately. Figure 3 As shown, in one example, the distance H2 from the stern bulkhead to the end of the stern ramp is 8500 mm. In this way, more space can be freed up for the cargo hold 10, thereby increasing the cargo hold volume and loading capacity of the ship.

[0038] In addition, the layout of the open deck is more compact, creating more space for the arrangement of other equipment on board.

[0039] The present invention rationally plans the positions of the steering gear compartment escape and mooring equipment, optimizes the position of the stern ramp, ensures the layout space of various equipment, reduces the space occupied by the stern ramp in the cargo hold, and maximizes the loading capacity of the ship.

[0040] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
