Description

Technical Field

[0001] The utility model relates to the technical field of ships, and particularly relates to a novel marine methanol tank structure. Background Art

[0002] With the increasingly strict environmental protection and emission regulations, the global shipping industry has entered the fuel transition stage and is developing rapidly towards low-carbonization. The replacement of traditional fuels is an inevitable trend. The application of methanol fuel is one of the key solutions for decarbonization in the current shipping industry.

[0003] Methanol fuel is clean, environmentally friendly, has high combustion efficiency, is economical and has high safety. However, its low energy density results in a large storage volume required for loading on ships. Due to the large storage volume required, the marine methanol tank structure is usually arranged at the aft cargo hold of the ship, resulting in the compression of the cargo hold capacity, reducing the cargo loading capacity and the economy of ship operation.

[0004] The prior art has the following disadvantages:

[0005] The existing methanol fuel tank structure is arranged above the double bottom of the cargo hold. According to the requirements of ship classification rules, an isolation empty tank needs to be set between the methanol fuel tank and the adjacent structure, which will cause a very large loss of cargo hold capacity in the aft cargo hold of the ship and reduce the economy of ship operation. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to overcome the above defects existing in the prior art and provide a novel marine methanol tank structure.

[0007] The utility model solves the above technical problem through the following technical solutions:

[0008] A novel marine methanol tank structure, which includes a methanol fuel tank arranged between the pipe tunnel and the cargo hold. Isolation tanks are provided between the methanol fuel tank and the pipe tunnel, and between the methanol fuel tank and the cargo hold; no isolation tank is provided between the methanol fuel tank and the ship outer plate, and the ship outer plate becomes the tank wall of the methanol fuel tank; a trough-shaped bulkhead for dividing the methanol fuel tank into two left and right tanks is provided in the middle of the methanol fuel tank.

[0009] Further, the trough strips of the trough-shaped bulkhead are distributed along the longitudinal direction of the ship.

[0010] Further, transverse stiffeners are provided on the ship outer plate inside the methanol fuel tank.

[0011] Further, the transverse stiffeners extend from the top to the bottom of the methanol fuel tank along the ship outer plate.

[0012] Further, longitudinal girders are provided inside the methanol fuel tank, and the longitudinal girders are fixedly arranged on the ship outer plate.

[0013] Furthermore, the longitudinal girder is fixedly connected to the transverse strong frame.

[0014] Furthermore, a horizontal large panel is fixedly installed inside the methanol fuel tank, and the horizontal large panel is fixedly installed on the bulkhead of the methanol fuel tank outside the pipe tunnel; the horizontal large panel is flush with the inner bottom plate at the top of the pipe tunnel.

[0015] Furthermore, the front and rear ends of the horizontal large panel are respectively fixedly installed on the front bulkhead and the rear bulkhead of the methanol fuel tank.

[0016] Furthermore, a transition bracket is fixedly installed inside the methanol fuel tank, and the transition bracket is fixedly installed on the outer hull plate; the transition bracket is flush with the inner bottom plate at the top of the pipe tunnel.

[0017] Furthermore, transition brackets are fixedly installed between the front bulkhead of the methanol fuel tank and the outer hull plate, and between the rear bulkhead of the methanol fuel tank and the outer hull plate.

[0018] The beneficial effects of the present utility model are as follows: Compared with the prior art, the present utility model not only ensures the layout and volume of the methanol fuel tank, reduces the loss of the cargo hold volume, but also reduces the use of hull steel, greatly improving the economy of the ship; the trough-shaped longitudinal wall form without stiffeners is adopted inside the methanol tank, which plays an effective supporting role and is conducive to the development of the special coating work of the methanol tank.

[0020] Figure 2 It is a schematic diagram of the weak frame structure of the preferred embodiment of the present utility model.

[0021] Figure 3 is Figure 2 the schematic diagram of the A-A section in Detailed Embodiments

[0022] The following is a preferred embodiment, and the present utility model will be described more clearly and completely in conjunction with the drawings.

[0023] As Figure 1 , Figure 2 and Figure 3 shown, a new type of marine methanol tank structure includes a methanol fuel tank 10 arranged between a pipe tunnel 20 and a cargo hold 30, and isolation empty tanks 40 are arranged between the methanol fuel tank 10 and the pipe tunnel 20, and between the methanol fuel tank 10 and the cargo hold 30.

[0024] No isolation empty tank is arranged between the methanol fuel tank 10 and the outer hull plate 11, and the outer hull plate 11 becomes the bulkhead of the methanol fuel tank 10.

[0025] In the middle of the methanol fuel tank 10, there is a trough-shaped bulkhead 12 for dividing the methanol fuel tank into two compartments on the left and right. The trough strips of the trough-shaped bulkhead 12 are distributed along the longitudinal direction of the ship.

[0026] On the outer hull plate 11 inside the methanol fuel tank, there is a transverse strong frame 13. The transverse strong frame 13 extends from the top to the bottom of the methanol fuel tank along the outer hull plate.

[0027] Inside the methanol fuel tank 10, there is a longitudinal girder 14, and the longitudinal girder 14 is fixedly arranged on the outer hull plate 11. The longitudinal girder 14 is fixedly connected to the transverse strong frame 13.

[0028] Inside the methanol fuel tank 10, a horizontal large panel 41 is fixedly arranged, and the horizontal large panel 41 is fixedly arranged on the bulkhead 15 outside the pipe tunnel of the methanol fuel tank; the horizontal large panel is flush with the inner bottom plate at the top of the pipe tunnel.

[0029] The front and rear ends of the horizontal large panel 41 are respectively fixedly arranged on the front bulkhead 16 and the rear bulkhead 17 of the methanol fuel tank.

[0030] Inside the methanol fuel tank 10, a transition bracket 42 is fixedly arranged, and the transition bracket 42 is fixedly arranged on the outer hull plate 11; the transition bracket is flush with the inner bottom plate at the top of the pipe tunnel.

[0031] Transition brackets 42 are fixedly arranged between the front bulkhead 16 of the methanol fuel tank and the outer hull plate 11, and between the rear bulkhead 17 of the methanol fuel tank and the outer hull plate 11.

[0032] In the present utility model, an isolation tank is arranged between the methanol fuel tank and the cargo hold, and between the methanol fuel tank and the pipe tunnel. The isolation tank can be an isolation empty tank or a compartment with an isolation function. No isolation tank is arranged between the methanol fuel tank and the outer hull plate, and the outer hull plate directly becomes the bulkhead of the methanol fuel tank. When the outer hull plate serving as the bulkhead of the methanol fuel tank is damaged, methanol can be directly dissolved in water and will not pollute water and air.

[0033] Compared with the conventional methanol fuel tank in terms of the structure of the present utility model, since the isolation tank between the methanol fuel tank and the outer hull plate is reduced, the height of the methanol fuel tank can be effectively reduced under the same fuel volume requirement. Compared with the conventional scheme, the structure of the present utility model increases the cargo hold volume and the side ballast tank volume.

[0034] In the present utility model, a bottom longitudinal girder and a transverse strong frame are arranged inside the methanol fuel tank, and a horizontal large panel and a transition bracket are arranged at the position of the inner bottom plate (i.e., the top position of the pipe tunnel). This kind of structure not only makes up for the weakening of the hull structure strength caused by the discontinuity of the inner bottom plate, but also further improves the structural strength of the methanol fuel tank.

[0035] A trough-shaped bulkhead is arranged in the methanol fuel tank as a partition structural member, which not only meets the support requirements for the methanol fuel tank but also meets the special painting requirements during the shipbuilding process.

[0036] Compared with the prior art, the present utility model not only ensures the layout and volume of the methanol fuel tank, reduces the loss of the cargo hold volume, but also reduces the use of hull steel, greatly improving the ship's economy; the trough-shaped longitudinal bulkhead form without stiffeners is adopted in the methanol tank, which plays an effective supporting role and is conducive to the development of special painting work for the methanol tank.

[0037] Although the specific implementation manners of the present 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 present utility model is defined by the appended claims. Without departing from the principle and essence of the present 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 present utility model.
