Description

[0001] FIT-UP APPARATUS FOR INSULATION PANEL STRUCTURE OF LIQUID GAS ISOLATING STRUCTURE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a piping device for a liquefied gas insulation structure, and more particularly, to a piping device for a liquefied gas insulation structure capable of improving the efficiency and productivity of a process for manufacturing a liquefied gas holding window.

The liquefied gas is a liquid made by cooling or compressing gas, and is a gas phase liquid phase change industrially at room temperature for convenience of transportation and storage. One of the most widely used and important resources in liquefied gas is Liquefied Natural Gas (LNG). Liquefied natural gas refers to a colorless transparent cryogenic liquid with methane-based natural gas cooled to -162 degrees Celsius and its volume reduced to 1/600.

As such liquefied gas is used as an important energy source, an efficient transportation method capable of transporting liquefied gas from a production base to various demand sites has been examined. As part of this effort, a liquefied gas transport vessel capable of transporting large volumes of liquefied gas through the sea has been developed.

The liquefied gas transport vessel shall be provided with a liquefied gas cargo hold capable of storing and storing the liquefied gas liquefied at a cryogenic temperature. Since the liquefied gas has a higher vapor pressure than the atmospheric pressure and has a boiling temperature of ultra-low temperature, in order to safely store and store such liquefied gas, the liquefied gas storage window must be made of a material that can withstand the extremely low temperature, It should be designed with a unique insulation panel structure to prevent intrusion.

Generally, the heat insulating structure of the liquefied gas holding window is composed of a structure in which a primary barrier, an upper insulating board, a secondary barrier and a lower insulating board are sequentially connected. This is to prevent additional leakage of the fluid in the secondary barrier, even if there is a small leakage of cryogenic fluid in the primary barrier.

Since the size of the liquefied gas hold is very large, tens of thousands of units are installed in the unitary box as the insulation structure of the liquefied gas hold. The heat insulating structure of the liquefied gas hold is formed by fixing a plurality of lower heat insulating boards having the same thickness on the inner wall of the hold, installing a secondary barrier on the lower heat insulating board, installing an upper insulating board and a primary barrier on the upper part of the secondary barrier Process.

It is necessary that the lower insulation board, the secondary barrier, the upper insulation board and the primary barrier laminated with the unit box are connected to the insulation structure of the adjacent unit box so as to ensure the hermeticity of the insulation structure. Particularly, in the case of the primary barrier and the secondary barrier, they are welded together with the adjacent primary barrier or the adjacent secondary barrier to ensure airtightness.

A welding operation is performed in a state where a part of the end portion overlaps between the primary barriers or the secondary barriers. In order to ensure the quality of the welding operation, the interval between adjacent primary barriers or secondary barriers must be minimized. The process of bringing the intervals between adjacent primary walls or adjacent secondary walls in close contact with each other is referred to as " fit-up ".

On the other hand, in the case of the primary barrier or the secondary barrier in which the pick-up process is performed, the shape of the primary barrier or the secondary barrier is not simple because it has wrinkles for relieving thermal stress and the like. Therefore, there is a need for research on a device capable of increasing the efficiency of the process of manufacturing a heat insulating structure of a liquefied gas holding window by easily and effectively performing a pick-up process.

The liquefied gas hold can be used to store and transport cryogenic liquefied gas. Liquefied gas is a liquid made by cooling or compressing gas. It includes Liquefied natural gas (LNG), Liquefied petroleum gas (LPG), and Dimethyl ether (DME).

Liquefied gas cargo holds include liquefied gas carriers such as LNG carrier, LNG RV (regasification vessel) carrier, LPG carrier or ethylene carrier, FSRU (Floating Storage Regulation Unit), FPSO (Floating Production Storage Offloading) Or Barge Mounted Power Plant (BMPP), or to marine floating plants with vaporization facilities. In addition, the liquefied gas cargo holds include not only the facilities installed on the sea, but also those used for facilities to store or produce liquefied gas installed on land.

Hereinafter, a membrane-type cargo hold of a liquefied gas holding cargo will be described as an example. FIG. 1 is a perspective view showing an example of a liquefied gas holding space heat insulating structure to which a fatigue apparatus 100 of a liquefied gas insulating structure according to an embodiment of the present invention is applied, and FIG. 2 is a perspective view of a liquefied gas insulating structure according to an embodiment of the present invention. Up device 100 is placed adjacent to each other. FIG. 1 and FIG. 2 are provided as an example to facilitate understanding of the present invention, and the components not related to the present invention may be variously changed.

1 and 2, a liquefied gas holding window surrounds a space capable of accommodating liquefied gas and includes a primary barrier 50 in direct contact with the liquefied gas, and a primary barrier 50 surrounding the primary barrier 50, A liquefied gas insulating structure that is insulated from the outside, and an outer wall that surrounds and supports the liquefied gas insulating structure.

The heat insulating structure can be made of a double heat insulating structure in order to improve the heat insulating performance and to facilitate repair and maintenance. Specifically, the heat insulating structure of the liquefied gas holding window may include a lower heat insulating board 20 installed on the outer wall side and an upper heat insulating board 30 installed on the upper side of the lower heat insulating board 20. [ An inner hull can be used as the outer wall and supports the load of the storage fluid.

The lower insulation board 20 may be coupled to the outer wall by various fixing members including a stud bolt or the like so that the lower insulation panel 20 can be firmly fixed to the outer wall. The lower reinforcement panel 21 may be made of a material such as plywood or the like and may be attached to the bottom surface of the lower heat insulation board 20 using an adhesive such as epoxy glue or the like.

On the upper portion of the lower insulation board 20, a lower sub-panel 22 may be laminated for installing a secondary barrier 40 to be described later. The lower sub-panel 22 may be made of a material such as plywood or the like as the lower reinforcement panel 21 and may be attached to the lower heat-insulating board 20 using an adhesive such as epoxy glue.

A panel fixing unit 25 for fixing the upper heat insulating board 30 may be provided on the upper side of the lower heat insulating board 20. The panel fixing unit 25 may be coupled to the upper surface of the lower sub-panel 22 and the panel fixing unit 25 may have a coupling portion to be engaged with the lower sub-panel 22 by a rivet or a screw- And a protrusion protruding upward from the sub panel 22 and engaging with the upper heat insulating board 30. [ The protrusions may be threaded on the outer circumferential surface and coupled with the upper heat-insulating board 30 in a threaded manner. The panel fixing unit 25 is welded to the secondary barrier 40 to be described later.

The insulating structure of the liquefied gas hold can include a secondary barrier 40 interposed between the upper and lower insulating boards 30 and 20. The secondary barrier 40 protects the lower insulation board 20 even if the primary barrier 50 loses airtightness, thereby greatly reducing the time and cost required for repair and maintenance.

The secondary barrier 40 may be made of a metallic material such as an INVAR, stainless steel (SUS), or an aluminum alloy in the same manner as the primary barrier 50, and may be formed of a rigid triplex and a shuffle triplex (Supple triplex) can be used.

The secondary barrier 40 may be attached to the lower insulation board 20 by welding. When the secondary barrier 40 is attached by welding, it is welded to an anchor strip 24 made of a metal material and joined to the lower sub-panel 22. The anchor strip 24 may be mechanically coupled to the lower sub-panel 22 by means of a rivet or the like and the anchor strip 24 may be received in a groove formed in the lower sub- As shown in Fig.

The anchor strip 24 is positioned below the weld line during welding between adjacent sheets of the secondary barrier 40 as described later, so that the secondary barrier 40 sheet can be prevented from being deformed by welding heat. The anchor strips 24 may be arranged in different directions to form an intersection. For example, two strips orthogonal to each other.

In Fig. 1, eight lower insulation boards 20 are disposed adjacent to each other, and a secondary barrier 40 having a shape corresponding to the shape of the anchor strip 24 provided on the lower sub-panel 22 is formed in eight lower insulation But it is not limited to the number and the shape of the board 20.

The secondary barrier 40 can be constituted by a plurality of secondary barrier 40 sheets and the secondary barrier 40 has a hole through which the panel fixing unit 25 can pass. After the installation of the secondary barrier 40 is completed, the secondary barrier 40 and the panel fixing unit 25 are welded to each other to ensure airtightness and continuity of the heat insulating structure.

After one secondary barrier 40 sheet is fixed, another secondary barrier 40 sheet is fixedly installed on one adjacent side. At this time, the sheets of the secondary barrier 40 and the sheets of the secondary barrier 40 adjacent to each other are disposed so as to overlap with each other on the adjacent edges.

The secondary barrier 40 may include a corrugation 41 to have a low surface stiffness. The corrugated portion 41 can elastically deform its shape corresponding to the thermal stress applied to the secondary barrier 40, thereby reducing the thermal stress at the welded portion.

The secondary barrier 40 includes a first corrugation 41-1 and a second corrugation 41-2 which are arranged in different directions and an intersection 42 where the two corrugations intersect. The thermal stress acting in the in-plane direction of the secondary barrier 40 can be relieved by the wrinkles 41 in different directions. That is, the thermal stress acting in the longitudinal direction of the first wrinkled portion 41-1 is canceled by the elasticity of the second wrinkled portion 41-2, and the thermal stress acting in the longitudinal direction of the second wrinkled portion 41-2 The thermal stress can be solved by the stretchability of the first wrinkle portion 41-1.

In FIG. 1, the two wrinkles 41 are arranged in directions orthogonal to each other. However, the wrinkles 41 may be formed in various numbers according to design requirements. For example, when the folds are arranged in three directions, they may be provided at an angle of 60 degrees with respect to each other.

The corrugated portion 41 provided in the secondary barrier 40 may be formed in a convex shape downward and may be located at the boundary of the adjacent lower heat-insulating board 20. Chamfer is formed at the corner of the lower heat insulating board 20 to prevent interference with the corrugated portion 41.

An upper reinforcing panel 31 may be coupled to the bottom surface of the upper insulating board 30 so that the upper insulating board 30 can be firmly fixed to the lower insulating board 20. The upper reinforcing panel 31 may be made of a material such as plywood or the like and may be attached to the upper heat insulating board 30 using an adhesive such as epoxy glue.

The upper insulating board 30 and the upper reinforcing panel 31 are provided with through holes 30a and 31a so that protrusions of the panel fixing unit 25 can be inserted or inserted. A thread is formed on the inner circumferential surface of the through holes 30a and 31a and the upper insulating board 30 can be fixedly installed by screwing the protruding portion of the panel fixing unit 25. [ The airtightness can be maintained by inserting the foam plug 30b into the through holes 30a and 31a.

The upper insulating board 30 may be provided in a size and shape corresponding to the area where the two lower insulating boards 20 are disposed adjacent to each other and may be fixed by the two panel fixing units 25, Can be prevented from rotating.

An upper sub-panel 32 may be provided on the upper surface of the upper insulation board 30 for installing the primary barrier 50. The upper sub-panel 32 may be made of a material such as plywood or the like and may be attached to the upper heat-insulating board 30 using an adhesive such as epoxy glue or the like.

An anchor strip (34) may be provided on the upper surface of the upper sub-panel (32). The anchor strip 34 may be made of a metal such as SUS and welded to the primary barrier 50 and may be mechanically coupled to the upper sub-panel 32 by rivets or the like. A groove 32a may be formed on the upper surface of the upper sub-panel 32 so that the anchor strip 34 may be seated and the anchor strip 34 may not protrude from the upper surface of the upper sub-

The anchor strips 34 may be arranged in different directions to form an intersection. For example, two strips orthogonal to each other and may be provided at a position corresponding to a corner shape of the primary barrier 50.

The primary barrier 50 may be made of a metal material such as INVAR, stainless steel (SUS), or aluminum alloy so as to maintain its physical and chemical state even at a low temperature.

Because the primary barrier 50 is in direct contact with the cryogenic storage fluid, it is exposed to rapid contraction and expansion. The primary barrier 50 may accumulate fatigue due to repeated heat shrinkage and thermal expansion, or may damage the welded portion during heat shrinkage and degrade the airtightness. Due to this problem, the primary barrier 50 includes the corrugations 51 to have an in-plane stiffness. The corrugated portion 51 can elastically deform its shape corresponding to the thermal stress applied to the primary barrier 50, thereby reducing the thermal stress at the welded portion.

The primary barrier 50 includes first and second corrugated portions 51-1 and 51-2 disposed at different directions and an intersection portion 52 where the two corrugations intersect with each other. The thermal stress acting in the in-plane direction of the primary barrier 50 can be relieved by the wrinkles 51 in different directions. That is, the thermal stress acting in the longitudinal direction of the first wrinkled portion 51-1 is canceled by the elasticity of the second wrinkled portion 51-2, and the thermal stress acting in the longitudinal direction of the second wrinkled portion 51-2 Can be solved by the stretchability of the first wrinkled portion 51-1.

On the other hand, since the liquefied gas holding window is very large in size, the heat insulating structures including the primary barrier 50 and the secondary barrier 40 are manufactured by arranging tens of thousands of unit boxes and connecting them to each other . 2, the primary barrier 50 or the secondary barrier 40 (hereinafter referred to as the barrier) is in close contact with the adjacent sub barrier 32 and the upper sub-panel 32, To be welded to the anchor strip of the anchor. In this case, a process of closely contacting the overlapping portions 55 between adjacent barriers with no gap is referred to as a fit-up process. As described above, in order to eliminate thermal stress, wrinkles 41, 51 And the intersecting portions 42 and 52, it is very difficult to stably pull up the adjacent barrier ribs with no gap therebetween, and the pick-up process is a very important process that determines the quality of the welding of the barrier.

In FIG. 2, the primary barriers 50 are shown as being placed adjacent to each other. In FIGS. 3 to 6, the fishing-equipment 100 of the liquefied gas-insulating structure according to the embodiment of the present invention is applied to the primary barrier But it should also be understood that the same applies to the primary barrier 50 as well as to the secondary barrier 40.
