1 to 3, an explosion flame inducing structure 1000 according to an embodiment of the present invention includes an upper module 100 and an inclined portion 200.

The topside module 100 includes a BOG processing module having a plurality of liquefaction modules, a generator module, an electric room module, a preprocessing module, a moisture removal module, a BOG (Boil-Off Gas) Room module, a liquefied natural gas cargo module, and the like.

Inside the upper module 100, equipment or equipment with a high possibility of explosion, that is, an explosive hazardous material (for example, a liquefaction facility or a liquefied natural gas cargo facility, etc.) can be accommodated.

Conventionally, in order to minimize the risk of mutual transfer between a plurality of upper modules 100 at the time of fire or gas leakage, a liquefied natural gas unloading module (unrepresented) among the plurality of upper modules 100 is separated from a plurality of liquefaction modules Or a plurality of liquefaction modules are arranged on the port side of the hull and the liquefied natural gas unloading module to which the LNG carriers are moored and connected is arranged on the starboard side of the hull.

However, even in such a case, a safety accident such as a large deck on the upper part of the hull due to an explosion occurring in the upper module 100 occurs.

In this embodiment, when an explosion occurs in the upper module 100, it is possible to induce the explosive flame to be ejected in a direction away from the upper portion of the hull, thereby minimizing the damage to the hull due to the explosion and, at the same time, The flame inducing structure 1000 can be realized.

Hereinafter, with reference to FIG. 1 to FIG. 3, the configuration of the explosive flame induction structure 1000 according to the present embodiment will be described in more detail.

The upper module 100 is a structure for accommodating explosive dangerous substances (not shown) on the inside as described above, and may be, for example, a box-like structure as shown in Fig.

In this case, the box-shaped upper module 100 may be spaced upward from the deck of the ship 10 by a plurality of support legs (unmarked). Accordingly, a space can be provided between the deck of the hull 10 and the lower portion of the upper module 100, and a passageway through which the operator can move the equipment can be provided.

As shown in FIG. 1, a plurality of upper modules 100 may be disposed adjacent to each other on the upper deck of the hull 10.

According to the present embodiment, the explosion flame inducing structure 1000 may further include a connecting bridge 300 connecting the plurality of upper modules 100 as shown in FIG.

By providing the connection bridge 300 to connect the upper modules 100 adjacent to each other in this manner, for example, in order to maintain and check the equipment contained in the upper module 100, that is, the explosion dangerous material, It is possible to directly move to the neighboring upper module 100 through the connection bridge 300 without moving, thereby shortening the moving copper line. As a result, it is possible to reduce the work time and cost required.

The inclined portion 200 is a member formed along the inner edge of the upper module 100 as shown in FIG.

The inclined portion 200 may guide the explosive flame to be ejected in a direction away from the upper portion of the hull 10 (see arrow direction in Fig. 2) when an explosion occurs in the upper module 100.

That is, when the explosion occurs in the upper module 100, the explosion flame may be ejected in all directions from the generation point. The explosion flame ejected in the lower direction and the side direction of the upper module 100, The upward direction of the upper module 100 can be induced.

Therefore, when the explosion occurs in the upper module 100, it is possible to guide the explosion flame in a direction away from the upper part of the ship, thereby minimizing damage to the ship due to the explosion. At the same time, It is possible to minimize the damage of workers who are located.

For this, the slope part 200 may be composed of multiple firewalls as shown in FIG.

3, the inclined portion 200 includes a first inclined surface 210 exposed to the outside and a second inclined surface 220 disposed on the inner side of the first inclined surface 210, . ≪ / RTI >

The first inclined surface 210 and the second inclined surface 220 may be made of materials capable of withstanding high temperatures and high pressures. Although not shown, the first inclined surface 210 and the second inclined surface 220 may form a convex curved surface so as to face the inner edge of the upper module 100.

Accordingly, the explosion flame can be naturally induced in the upward direction of the upper module 100 by the inclined portion 200 of the curved surface.

The inclined portion 200 includes the first inclined surface 210 and the second inclined surface 220. However, the present invention is not limited thereto, and if necessary, Three or more inclined surfaces may be included.

Referring to FIG. 3, a step 230 connected to the connection bridge 300 may be installed above the first inclined surface 210.

In this case, the step 230 may be made of a material capable of withstanding high temperature and high pressure, like the first inclined surface 210 and the second inclined surface 220. Thus, the step 230 may function as a primary barrier wall to withstand the explosion flame prior to the first ramp 210 and the second ramp 220. [

By providing the step 230 at the upper side of the first inclined surface 210 as described above, the operator can directly move to the neighboring upper module 100 through the connecting bridge 300 without having to move through the hull deck, Can be shortened. As a result, the time required for inspecting or repairing equipment (i.e., explosion hazardous materials) contained in the upper module 100 can be reduced.

As described above, according to the present embodiment, when the explosion occurs in the upper module 100, the explosion flame can be induced to be blown away from the upper portion of the ship, thereby minimizing damage to the hull due to the explosion, The flame inducing structure 1000 can be realized.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that those skilled in the art will appreciate that addition, alteration, deletion, or addition of components The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
