Description

Liquefied Gas Cargo Hold Panel The present invention relates to a liquefied gas cargo tank panel, and more specifically, to a liquefied gas cargo tank panel in which the corner steel and the upper panel are provided as a single unit, thereby eliminating the need for a separate installation of the corner steel, which can increase work convenience and efficiency. Generally, natural gas is transported in a gaseous state through onshore or offshore gas pipelines, or transported to distant consumption sites in the form of liquefied natural gas (LNG) stored on LNG carriers. Generally, for ease of storage and transportation of natural gas, it is managed and operated by changing the phase of natural gas into liquefied natural gas (LNG), a colorless, transparent ultra-low temperature liquid that is cooled to about -162 degrees and reduced in volume to 1/600. Liquefied natural gas (LNG) is a fossil fuel consisting mainly of methane and containing small amounts of ethane, propane, etc., and has recently been gaining attention as a low-pollution energy source in various technological fields. In addition, an LNG carrier for unloading LNG at an onshore destination after sailing the sea, or an LNG RV (Regasification Vessel) for unloading LNG in the form of natural gas after arriving at an onshore destination after sailing the sea, includes a tank (commonly referred to as a ‘cargo tank’) capable of withstanding the cryogenic temperature of liquefied natural gas. Here, cargo tanks are manufactured in spherical and membrane types. In particular, membrane type cargo tanks are currently the most widely used because they have a larger loading capacity than spherical type cargo tanks and are easier to manufacture. Conventional membrane-type cargo tanks have very stringent requirements for safely storing liquefied natural gas at cryogenic temperatures. Furthermore, since constructing a membrane-type cargo tank that meets these stringent conditions requires various complex processes, there is a problem of wasting not only a large workforce but also significant resources. In addition, conventional liquefied gas cargo tanks had a problem of reduced work convenience and efficiency because the panel anchors at the corners were located within the inner area of the corner steel, requiring the corner steel to be installed separately after the insulation panels at the corners were assembled. Figure 1 shows a conventional liquefied gas cargo tank panel. FIG. 2 is a perspective view showing a liquefied gas cargo tank panel according to the present embodiment. FIG. 3 is a side view showing a liquefied gas cargo tank panel according to the present embodiment. The following describes the embodiments of the present invention in detail with reference to the accompanying drawings. The following embodiments are presented to sufficiently convey the concept of the present invention to those skilled in the art to which the present invention pertains. The present invention is not limited to the embodiments presented herein and may be embodied in other forms. In order to clarify the present invention, the drawings may omit the illustration of parts unrelated to the description and may slightly exaggerate the size of components to aid understanding. Figure 1 shows a conventional liquefied gas cargo tank panel. Referring to FIG. 1, a conventional liquefied gas cargo tank panel (10) is described as follows. First, a reinforcing panel (11) located on the upper part of the upper panel (12) may be provided with a first through hole (11a). This first through hole (11a) may be connected to a second through hole (12a) formed by penetrating the upper panel (12) at a position corresponding to the first through hole (11a). Accordingly, the reinforcing panel (11) and the upper panel (12) can be joined and fixed to the lower panel using fastening means (13), such as bolts and nuts, inserted into the first through hole (11a) and the second through hole (12a). That is, the conventional liquefied gas cargo tank panel (10) had a problem of reduced convenience and efficiency of work because, after assembling the reinforcing panel (11) and the upper panel (12), corner steels had to be installed separately on the surface of the reinforcing panel (11) last. FIG. 2 is a perspective view showing a liquefied gas cargo tank panel according to the present embodiment, and FIG. 3 is a side view showing a liquefied gas cargo tank panel according to the present embodiment. Hereinafter, a liquefied gas cargo tank panel (100) according to an embodiment of the present invention will be described in detail with reference to FIG. 2 and FIG. 3. The liquefied gas cargo tank panel (100) according to the present embodiment comprises: a plurality of upper panels (110) arranged at regular intervals and arranged in a curved shape corresponding to the shape of the corner portion and arranged in a corner portion of the liquefied gas cargo tank; a lower panel (120) arranged at the bottom of the up
