BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a system scaffold assembly for insulation work of an LNG cargo hold and an LNG cargo hold module using the same. More specifically, a system scaffold for the operation of an inner insulation layer of an LNG cargo hold is manufactured in a separate outer yard and is transported in a state of being coupled to and supported by a floor block of the hull to be supplied to the ship building yard. Which can solve the manufacturing capacity limitation problem of the LNG cargo hold and enable the inner insulation layer operation to be carried out on the LNG cargo hold with a more convenient and quick process, and a LNG cargo hold module using the same.

In general, natural gas is transported in the form of gas through land or sea gas pipelines, or stored in a LNG carrier in the form of liquefied natural gas (hereinafter referred to as "LNG"), Lt; / RTI >

Such LNG is obtained by cooling natural gas to a cryogenic temperature, for example, approximately -163 DEG C, and its volume is reduced to approximately 1/600 of that of natural gas in a gaseous state, so that it is suitable for long distance transportation through the sea.

These LNGs are transported through LNG transporting vessels, transported through the sea, unloaded to landfill sites, carried on LNG RV (LNG Regasification Vessel), transported through the sea, reached to land requirements, recharged and unloaded as natural gas LNG carriers and LNG RVs are equipped with LNG cargo holds capable of withstanding cryogenic temperatures of LNG.

In addition, demand for floating floating structures such as LNG Floating Production Storage and Offloading (FPSO) and LNG FSRU (Floating Storage and Regasification Unit) is increasing, and these floating structures are installed in LNG carriers or LNG RVs. LNG cargo holds.

Here, LNG FPSO is a floating marine structure that is used to directly liquefy natural gas produced from the sea and store it in a cargo hold, and to transfer LNG stored in cargo hold to LNG transport, if necessary.

In addition, the LNG FSRU is a floating floating structure that stores LNG unloaded from an LNG carrier at a sea off the sea, and then vaporizes the LNG if necessary to supply it to the customer.

Such LNG hold is divided into independent tank type and membrane type depending on whether the insulation for storing the LNG at a cryogenic temperature directly acts on the load of the cargo. Separate tank-type cargo holds that do not directly affect the load of the cargo are divided into MOSS type and IHI-SPB type. Membrane type cargo hold that the insulation acts directly on cargo load is GT NO 96 type and TGZ Mark III type Is divided. Double membrane type holds generally have a thermal insulation layer on the inner wall of the hull.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a conceptual view schematically showing a structure of a conventional LNG cargo hold according to the prior art; FIG.

The conventional LNG cargo hold 10 according to the related art is formed as a LNG cargo hold 10 as shown in FIG. That is, the side shell block 40, which is formed to form the bottom of the LNG cargo hold 10 and is joined to both lateral ends of the bottom block 30 so as to form the side wall of the hull, Is formed to form a side wall of the LNG cargo hold (10). A trunk deck block 60 is coupled to the upper end of the side shell block 40 to block the inner space of the LNG cargo hold to form a ceiling wall of the LNG cargo hold 10. Of course, although not shown, separate bulkhead blocks (not shown) may be coupled to the front and rear longitudinal sides of the bottom block 30. In this manner, the LNG cargo holds 10 are formed to have one sealed interior space.

A separate heat insulating layer 70 is formed on the inner wall surface of the LNG storage 10 for external heat insulation. The heat insulating layer 70 and the Inbar steel are sequentially stacked.

The insulation layer 70 is fabricated to have a basic structure of the LNG cargo hold 10, and then subjected to a thermal insulation layer construction process during the wall drying process of the ship. In order to construct such a heat insulating layer 70, a separate pedestal 20 for insulation work is installed inside the LNG cargo hold 10 as shown by a dotted line in FIG. The system footrest 20 is formed to have a plurality of worktables, and the work space of the worker is secured through the worktable. The worker performs the construction work of the insulation layer 70 through the workbenches of these multiple layers.

The system pedestal 20 is disassembled from the inner space of the LNG cargo hold 10 when the heat insulating layer 70 is completed, is taken out to the outside, and is detachably coupled to a plurality of horizontal members, vertical members, Since it is seated on the upper surface of the heat insulating layer 70 installed on the bottom surface in the process of constructing the heat insulating layer, it is formed in a very light form so as to prevent the heat insulating layer 70 from being damaged due to its own weight.

The system pedestal 20 is inserted into the dock together with the floor block 30 in a state where the floor block 30 has been manufactured. In this state, that is, when the system pedestal 20 is seated in the floor block 30 The side shell block 40 constituting the left and right lateral side walls of the LNG cargo holds 10 and the trunk deck block 60 constituting the ceiling walls of the LNG cargo holds 10 are performed. Of course, although not shown, a coupling operation of a bulkhead block (not shown) constituting the front and rear longitudinal side walls of the LNG cargo holds 10 is also performed. Accordingly, the LNG cargo hold 10 is configured such that its internal space is sealed through the bottom block 30, the side shell block 40, the bulkhead block, and the trunk deck block 60.

The system foot plate 20 is disposed in the inner space of the LNG cargo hold 10 through the above process. At this time, the system foot plate 20 is manufactured at the site yard inside the shipyard where the ship is to be dried.

In recent years, due to the increase in LNG demand, the order volume for LNG carriers has been increasing. Due to the relatively long drying period for LNG carriers, the field yard inside the shipyard is in excess of its production capacity in terms of space. And it is difficult to secure an additional yard, which is causing many difficulties in the shipbuilding process.

FIGS. 7 to 10 are views schematically showing a configuration of a system scaffold assembly and a LNG cargo hold module including the same according to another embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

2 and 3 are conceptual diagrams schematically showing the configuration of a system scaffolding assembly for insulation work of an LNG hold in accordance with an embodiment of the present invention.

The system scaffold assembly for inspecting an LNG hold according to an embodiment of the present invention is installed in an internal space of an LNG cargo hold for the operation of an inner insulation layer of an LNG cargo hold. The scaffold assembly includes a floor block 200 forming a bottom of the LNG cargo hold, And a system pedestal 100 formed to have a worktable 110 of a pedestal.

The bottom block 200 not only forms the bottom of the LNG cargo hold but also forms the bottom of the hull and can be constructed as a double bottom structure.

As shown in FIGS. 2 and 3, the system scaffold 100 includes a plurality of horizontal frames 101, a vertical frame 102, a vertical frame 103, The diagonal frame 102 and the diagonal frame 103 are coupled to each other so as to cross each other.

The system scaffold 100 is manufactured in a separate outer yard and is transported in a state of being coupled to and supported by the floor block 200 and supplied to the ship building yard. At this time, the system scaffold 100 may be configured to be supported on the upper surface of the floor block 200, and the lower end thereof may be coupled and supported to the floor block 200 through a welding (T) method.

In other words, the system scaffold assembly P according to an embodiment of the present invention is configured such that the system scaffold 100 is manufactured at a separate external yard rather than at the field yard inside the shipyard, And is connected to the block 200 by a welding method. In this state, the boat 200 is maritimely transported through a barge (not shown) and supplied to the ship drying yard.

Therefore, since it is not necessary to manufacture the system scaffold 100 in the field yard inside the shipyard, it is possible to prevent the production capacity from exceeding the yard in terms of space. Particularly, when manufactured in an outer yard, the boat is transported in a maritime transportation manner through a barge or the like while being coupled to the floor block 200. At this time, the system floorboard 100 is coupled and supported to the floor block 200 in a welding manner , A stable structure can be achieved even in a severe sea environment such as waves or winds during the sea transportation process.

The system pedestal 100 may include a plurality of horizontal frames 101 and a plurality of vertical frames 102 coupled to each other as described above. And the diagonal frame 103 is coupled to the space between the horizontal frame 101 and the vertical frame 102 as required. Thus, at least some of the plurality of vertical frames 102 may be configured such that the bottom end is welded (T) to the top surface of the bottom block 200.

At this time, all of the plurality of vertical frames 102 may be welded to the upper surface of the bottom block 200, but the reason why the vertical frame 102 is welded is merely to maintain a stable structure in the maritime transportation process, In the process of working the insulating layer of the LNG cargo hold, the vertical frame 102 must be detachable from the bottom block 200 in the working process, so that only some of the vertical frames 102 It is preferable to be selectively welded (T). This is because welding (T) bonding of the vertical frame 102 must be separated again by the operator in the insulating layer working process of the actual LNG cargo hold. In order to perform this separation operation quickly and conveniently, only a minimum of the vertical frame 102 It is preferable to weld-join.

In addition, the vertical frame 102 may be welded to the bottom block 200 by being disposed at least one on each of the right and left lateral ends of the bottom block 200.

In more detail, the system scaffold 100 is configured such that multiple worktables 110 are formed along the perimeter of the respective layers, as shown in FIGS. 2-3. This is because the system scaffold 100 is installed in the inner wall surface of the LNG cargo hold for the purpose of working as a heat insulating layer. Therefore, the system scaffold 100 can be installed around the inner wall surface of the LNG cargo hold, Accordingly, a plurality of worktable 110 for securing work space of the worker are formed.

Accordingly, the vertical frame 102 is concentrated on the right and left transverse end portions of the floor block 200 on the load supporting structure. Any one of the vertical frames 102 is welded to the upper surface of the floor block 200 In order to effectively maintain the stable structure without collapsing or separating away from the left and right vibrations during the sea transportation, at least one or more than one vertical block 102 disposed at the right and left lateral ends of the floor block 200 200). If necessary, a separate vertical frame 102a may be welded to the bottom block 200 in addition to the vertical frame 102 constituting the existing system footstep 100, will be.

In addition, the horizontal frame 101 is arranged such that a plurality of worktables 110 of a plurality of layers can be formed along the peripheries of the layers, respectively. At least one layer F1 and a lower layer In the uppermost layer F2, the workbench 110 can be arranged to be formed in the entire horizontal region of the layer.

For example, as shown in FIG. 2 and FIG. 3, the uppermost floor 9 and the lower three floors F1 are formed such that the worktable 110 is formed in the entire horizontal region of the floor .

According to this structure, the entire structure of the system scaffold 100 is connected through the two layers F1 and F2 to form a more stable structure. Particularly, , The center of gravity of the system scaffold 100 moves downward as a whole, so that a more stable structure is achieved.

Although the structure in which the system scaffold 100 is welded to the floor block 200 has been described above as a structure for coupling the system scaffold 100 to the floor block 200, The footrest 100 may be coupled to and supported by the floor block 200 through the support bracket 100. [ The support jig structure 300 may be applied together with the weld joint structure of the system scaffold 100 or may be separately applied to support the system scaffold 100.

The support jig structure 300 may be coupled to the bottom block 200 in such a manner that the support jig structure 300 is vertically disposed at the edge of the bottom block 200. For example, it may be formed in the form of a simple plate steel plate 320 and coupled to both lateral ends of the bottom block 200, in which case it is preferably detachably coupled through a separate coupling hole 321 Do. That is, since the support jig structure 300 is for a stable structure during the sea transportation of the system scaffold 100, it must be removed in the process of working the insulation layer of the actual LNG cargo hold.

3, the support jig structure 300 may include a side shell block 310 that is joined to both lateral ends of the left and right lateral sides of the floor block 200 to form side walls of the LNG cargo hold have. The side shell block 310 constitutes the wall of the hull and constitutes the wall of the LNG cargo hold together with the bottom block 200. The system pedestal assembly P according to the embodiment of the present invention is thus constructed in the same manner as the floor block 200, The system pedestal 100 may be coupled to and supported by the inner space in a state where the inner shell 200 and the side shell block 310 are coupled to each other.

That is, as shown in FIG. 2, by applying the support jig structure 300 to the side shell block 310 coupled to the bottom block 200 rather than simply forming and separating the support jig structure 300 in the form of a plate steel plate 320, It is possible to perform the heat insulating layer operation more quickly and conveniently without re-separating the jig structure 300.

Although the support jig structure 300 may support the system pedestal 100 in a form of simply pressing both the left and right ends of the system pedestal 100 in contact with each other, May be coupled to each other in lashing engagement with a separate lashing rope 330 to the support jig structure 300 according to one embodiment. At this time, the lashing rope 330 may be coupled to both ends of the horizontal frame 101 of the system scaffold 100 to be lashed with the support jig structure 300.

The work platform 110 of the system footstep 100 is formed in such a manner that a plate-shaped work platform is seated and coupled to a plurality of layers formed by the horizontal frame 101. At this time, (110) may be formed in the form of a lattice plate having a lattice structure as shown in an enlarged view of Figs.

Since the lattice type plate is formed of a material having light and high strength characteristics such as aluminum and a plurality of through holes 111 are formed in the work table 110 by the lattice type plate, ), The weight of the self-weight decreases, and at the same time, the rainwater flows downward and the water absorption is reduced, resulting in an additional weight reduction effect. Therefore, the system foot plate 100 can be made lighter overall as a whole. In other words, the conventional workbench 110 according to the related art uses wood plywood or the like. In this case, since the weight of the wood plywood itself is large and the weight of the wood plywood absorbs moisture, an additional weight increase occurs. However, this problem can be effectively solved through the use of a lattice plate made of lightweight material such as aluminum.

4 and 5 are conceptual views schematically showing the configuration of a system scaffolding assembly for insulation of an LNG hold according to another embodiment of the present invention. FIG. 2 is a conceptual diagram schematically showing a plan view in FIG.

4 to 6, the horizontal pedestal 101 and the vertical frame 102 constituting the pedestal 100 of the system are installed in the pedestal assembly P for insulating the LNG hold according to another embodiment of the present invention Each of which includes a main member M having a relatively high strength and a sub member S having a relatively low strength.

The system scaffold assembly P shown in Figs. 4 to 6 is the same as the above-described structure except that the horizontal frame 101 and the vertical frame 102 are configured to have a main member M and a sub member S, respectively Hereinafter, a brief description will be given focusing on the differences from the structures described in FIG. 2 and FIG.

The main member M and the sub member S may be formed in the shape of a hollow pipe and the shape or material of the main member M may be formed to be different from that of the sub member S .

At this time, the main member M may be arranged to form the basic skeleton structure of the system foot plate 100, and the sub member S may be additionally coupled to the main member M. 4 to 6, the main member M is arranged to form the basic skeletal structure of the system foot plate 100, and the sub member S is arranged on the main member M as shown in Fig. May be configured to additionally couple.

When the vertical frame 102 and the horizontal frame 101 of the system scaffold 100 are formed of the main member M and the sub member S as described above, (Not shown).

At this time, the main member M of the vertical frame 102 welded to the upper surface of the bottom block 200 may be configured to be distributed over a whole area of the bottom block 200. That is, the main member M may be arranged to form the basic skeleton structure of the system scaffold 100 as described above. In this case, the total weight of the system scaffold 100 is distributed evenly to the floor block 200 For this purpose, the main member M of the vertical frame 102 may be configured so that a plurality of the main members M are uniformly distributed over the entire area of the bottom block 200. [ In addition, the main member M of the vertical frame 102 distributed and arranged in this manner can be welded to the upper surface of the floor block 200, respectively.

When the support jig structure 300 is coupled to the floor block 200, the lashing rope 330 is coupled to the main member M of the horizontal frame 101, (M) to the support jig structure (300).

Of course, the support jig structure 300 is not applied in the form of the side shell block 310 and the bulkhead block 350 forming the side wall of the LNG cargo hold, but is applied in the form of a simple steel plate as shown in FIGS. 2 and 4 .
