Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a longitudinal passageway structure for a B-type liquefied gas carrier deck. Background Technology

[0002] Large B-type liquefied gas carriers typically have a single-layer raised deck. Generally, a longitudinal passage from the engine room to the bow needs to be arranged on both the port and starboard sides of the top of the side ballast tanks to provide personnel access and cable routing requirements in case of severe weather, ensuring personnel safety.

[0003] Traditionally, the passageway layout is located on the top of the side ballast tanks in the empty compartments on both port and starboard sides. This occupies a significant amount of ballast tank volume, reduces the overall ballast water volume, and affects the height of the ship's manifold area, thus impacting cargo loading and unloading. Solving this problem usually requires considerable expense, such as finding space throughout the ship to add ballast tanks or modifying the design of the raised deck, etc.

[0004] Traditional design schemes arrange a passageway on each of the port and starboard sides of the top of the side ballast tank. The main disadvantages of this method are: (1) The passageway arrangement on the top of the ballast tank will occupy part of the ballast tank volume, affecting the overall ballast water volume. Solving this problem usually requires considerable cost. (2) The cables and piping systems are exposed to the open air, which is not conducive to protection and antifreezing measures. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned defects in the existing technology and provide a longitudinal passage structure for the deck of a B-type liquefied gas carrier.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] A longitudinal passageway structure for a type B liquefied gas carrier deck is provided. The liquefied gas carrier has a raised deck above its upper deck, comprising a raised deck top plate and raised deck ramps. Raised deck ramps are located on both sides of the raised deck top plate and are connected to the upper deck. The liquefied gas carrier has side ballast tanks located below the upper deck. Longitudinal passageway side plates are fixed below the raised deck top plate, and a longitudinal passageway bottom plate is fixed to the inner side of the raised deck ramps. The raised deck top plate, raised deck ramps, longitudinal passageway side plates, and longitudinal passageway bottom plate form a longitudinal passageway compartment. Each of the two raised deck ramps has a longitudinal passageway compartment on its inner side.

[0008] Furthermore, the longitudinal passageway extends forward from above the engine room to the bow of the ship.

[0009] Furthermore, the longitudinal passageway cabin has pedestrian passage space for personnel passage.

[0010] Furthermore, the longitudinal passageway compartment has cable storage space for accommodating piping systems and cables.

[0011] Furthermore, the piping and cables within the cable containment space are distributed longitudinally along the ship.

[0012] Furthermore, the bottom plate of the longitudinal channel is distributed laterally.

[0013] Furthermore, the longitudinal passage side plate includes an upper side plate and a lower side plate, the top of the upper side plate being connected to the bottom of the raised deck top plate, the top of the lower side plate being connected to the bottom of the upper side plate, and the bottom of the lower side plate being connected to the longitudinal passage bottom plate.

[0014] Furthermore, the upper side plates are vertically distributed, while the lower side plates are obliquely distributed.

[0015] Furthermore, reinforcing ribs are provided on both the longitudinal channel side plates and the longitudinal channel bottom plate.

[0016] Furthermore, the longitudinal passageway is located above the upper deck.

[0017] The beneficial effects of this invention are as follows: This invention arranges a passageway compartment on each of the port and starboard sides below the raised deck, ensuring the required overall ballast water volume without occupying the volume of the side ballast tanks. This design also increases the area of ​​the raised deck; due to the added passageway bulkhead, the overall longitudinal strength and rigidity of the deck are improved, allowing for a corresponding reduction in the deck plate thickness. This passageway design ensures that crew members can move freely from the engine room to the bow, guaranteeing their safety. Cables and some piping systems placed on the deck can be arranged within this passageway, which is more conducive to the protection and maintenance of cables and piping systems, and also facilitates the implementation of anti-freezing measures. This invention, by arranging a longitudinal passageway compartment on each of the port and starboard sides below the raised deck, does not occupy the volume of the side ballast tanks, increases the ballast water volume significantly, meets the overall height requirements of the ship's manifold area, and is beneficial for loading and unloading cargo.

[0018] Figure 1 This is a schematic diagram of a preferred embodiment of the present invention. Detailed Implementation

[0019] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0020] like Figure 1 As shown, a longitudinal passageway structure for a B-type liquefied gas carrier deck is provided inside the liquefied gas carrier. A raised deck is provided above the upper deck 20 of the liquefied gas carrier. The raised deck includes a raised deck top plate 11 and a raised deck ramp 12. Both sides of the raised deck top plate 11 are provided with raised deck ramps 12, and the raised deck ramps 12 are connected to the upper deck 20.

[0021] The liquefied gas carrier is equipped with a side ballast tank 21, which is located below the upper deck 20.

[0022] A longitudinal passage side plate 13 is fixedly connected below the top plate 11 of the raised deck, and a longitudinal passage bottom plate 14 is fixedly connected to the inner side of the inclined plate 12 of the raised deck. The longitudinal passage bottom plate 14 is distributed laterally.

[0023] The raised deck top plate 11, the raised deck inclined plate 12, the longitudinal passage side plate 13, and the longitudinal passage bottom plate 14 form the longitudinal passage compartment 10.

[0024] The longitudinal channel side panel 13 includes an upper side panel 15 and a lower side panel 16. The upper side panel 15 is vertically distributed, and the lower side panel 16 is obliquely distributed.

[0025] The top of the upper side plate 15 is connected to the bottom of the raised deck top plate 11, the top of the lower side plate 16 is connected to the bottom of the upper side plate 15, and the bottom of the lower side plate 16 is connected to the longitudinal channel bottom plate 14.

[0026] Both the longitudinal channel side plate 13 and the longitudinal channel bottom plate 14 are provided with reinforcing ribs.

[0027] The longitudinal passageway 10 is located above the upper deck 20.

[0028] Each of the two raised deck ramps 12 has a longitudinal passageway compartment 10 on its inner side.

[0029] The longitudinal passageway 10 extends forward from above the engine room to the bow of the ship.

[0030] The longitudinal passageway compartment 10 has a pedestrian passageway space for personnel passage.

[0031] The longitudinal passageway compartment 10 has a conduit space for housing piping and cables. The piping and cables within the conduit space are distributed longitudinally along the ship.

[0032] In this invention, a longitudinal passageway from the engine room to the bow is arranged on each of the port and starboard sides below the raised deck, which does not occupy the volume of the side ballast tanks and ensures the overall required ballast water volume.

[0033] In this invention, the area of ​​the raised deck is increased; due to the addition of a longitudinal passage wall at the raised deck, the overall longitudinal strength and stiffness of the raised deck are increased, and the thickness of the raised deck plate is correspondingly reduced.

[0034] In this invention, the longitudinal passageway design ensures a longitudinal passage for crew members from the engine room to the bow, thus guaranteeing their personal safety.

[0035] In this invention, the longitudinal passageway design allows cables and some pipe systems placed on the deck to be arranged in the passageway, which is more conducive to the protection and maintenance of cables and pipe systems, and also facilitates the implementation of anti-freezing measures.

[0036] This invention features a passageway compartment on each of the port and starboard sides below the raised deck, ensuring the required ballast water volume without encroaching on the side ballast tank volume. This design also increases the area of ​​the raised deck; the addition of passageway bulkheads improves the overall longitudinal strength and rigidity of the deck, allowing for a corresponding reduction in the deck plate thickness. This passageway design ensures crew members can move freely from the engine room to the bow, guaranteeing their safety. Furthermore, this passageway design allows for the placement of cables and some deck piping, facilitating their protection and maintenance, and enabling the implementation of anti-freezing measures.

[0037] This invention arranges a longitudinal passageway compartment on each of the port and starboard sides below the raised deck, which does not occupy the volume of the side ballast tank, increases the ballast water volume significantly, meets the overall height requirements of the ship's manifold area, and is beneficial for the loading and unloading of cargo.
