Description

Technology Field

[0001] The present invention relates to a ship. Background Technology

[0002] In the shipbuilding industry, which consists of design, construction, and delivery starting from a ship order, operational profitability is crucial throughout the process. One of the factors determining profitability is productivity derived from the shipbuilding method, and the shipbuilding industry is striving to improve this productivity. For this reason, the block construction method was introduced.

[0003] The block construction method is a process in which a hull is first divided into hundreds or more blocks, each block is assembled, and then these multiple blocks are sequentially loaded onto a slipway to assemble a single hull.

[0004] Various outfitting components are individually mounted on separately manufactured blocks. These components are electronic devices installed to enable the vessel to operate and function normally, and can include a wide variety of items such as communication devices, ventilation systems, and various power devices.

[0005] In other words, ships are larger in scale than ordinary buildings and are produced as a single movable product through the assembly of numerous components and equipment; the shipbuilding process can be divided into hull construction, outfitting, and painting.

[0006] Hull construction refers to the construction in which the hull is assembled using the block construction method.

[0007] Outfitting work refers to the installation of various mechanical and electrical devices, including the main engines necessary for the operation of the ship, onto the hull; work such as piping and wiring to connect these devices into a single system; and construction of crew quarters.

[0008] Painting work refers to the overall process of painting the surface and interior of a hull to prevent rust. In other words, painting work is carried out according to the progress of the construction, such as by shot-blasting to completely remove rust and applying a primary coat of paint in a workshop or factory before the hull material is processed. Once the block is completed, block painting is performed again, and after it is loaded into the dock and the final welding is completed, a finishing coat of paint is applied just before the launching operation.

[0009] However, the space above the bulb at the bow of the ship, particularly, and the space adjacent to the propeller at the stern, constitute dead space as narrow areas that are difficult for workers to access. Due to spatial constraints, it is difficult to perform tasks such as painting in these dead spaces.

[0010] If painting is not performed on the steel hull, meaning there is no painted surface—that is, if the interior of the dead space is difficult to apply and inspect—the steel plates (and / or welds) are not protected by the painted surface, leading to problems such as condensation and corrosion caused by temperature differences. The problem to be solved

[0011] The problem that the present invention aims to solve is to provide a ship that can prevent condensation and corrosion in dead space and improve strength.

[0012] The problems of the present invention are not limited to those mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below. means of solving the problem

[0013] An aspect of the vessel according to the present invention for achieving the above objective comprises a block unit having a dead space formed in the hull that is difficult for a worker to enter, and a filling portion filled in the block unit so as not to come into contact with air.

[0014] The above filling part can be provided as cement and hardened after being filled into the block unit.

[0015] The above dead space may form a first space which is the upper space of the bulb at the bow section, or a second space which is the upper space of the propeller at the stern section, and the block unit may surround at least one of the first space or the second space.

[0016] Specific details of other embodiments are included in the detailed description and drawings. Effects of the invention

[0017] In the ship according to the present invention, even if a paint surface is not formed in a dead space such as a second space, the first space, which is the upper space of the bulb where it is difficult to form a paint surface, and the upper space of the propeller, condensation and corrosion can be prevented by filling with a filling material such as cement, and reinforcement by cement can be achieved. Brief explanation of the drawing

Figure 3 is a drawing showing the cross-sectional view of II in Figure 2. Figure 4 is a drawing showing area B of Figure 1. Figure 5 is a drawing showing the cross-sectional view of line II-II of Figure 4. Specific details for implementing the invention

[0019] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. The advantages and features of the present invention, and the methods for achieving them, will become clear by referring to the embodiments described below in detail together with the attached drawings. However, the present invention is not limited to the embodiments disclosed below but can be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same components.

[0020] FIG. 1 is a drawing illustrating a ship according to an embodiment of the present invention, FIG. 2 is a drawing illustrating region A of FIG. 1, and FIG. 3 is a drawing illustrating a cross-sectional view of II of FIG. 2. Additionally, FIG. 4 is a drawing illustrating region B of FIG. 1, and FIG. 5 is a drawing illustrating a cross-sectional view of II-II of FIG. 4.

[0021] Referring to FIGS. 1 to 5, a vessel (100) according to an embodiment of the present invention may include a hull (110) including a block unit (115) and a filling section (150). The vessel (100) of the present embodiment may be a vessel that operates a voyage, such as a container ship and an LNG carrier, but this is merely an example and may be various other vessels.

[0022] The hull (110) may extend from the bow toward the stern. For example, the hull (110) may consist of a bow section (not shown), a midsection (not shown), and a stern section (not shown). A bulb (111) for the operational efficiency of the vessel may be provided in the bow section, and a propeller (140) and a rudder (not shown), etc., may be installed in the stern section.

[0023] However, as shown in FIGS. 3 and FIGS. 5, unlike the central part, the bow and stern parts can be formed with a structure in which the width of the bow decreases toward the bow and the width of the stern decreases toward the stern for the sake of the ship's operational performance.

[0024] In addition, as shown in FIGS. 2 and 4, the first space (110S1), which is the upper space of the bulb (111) in the bow section, and the second space (110S2), which is the upper space of the propeller (140) in the stern section, are narrower in width compared to the upper and lower spaces of the first space (110S1) and the second space (110S2), thus forming a dead space that is difficult for a worker to enter.

[0025] In this embodiment, the block unit (115) surrounding the first space (110S1) and the second space (110S2), which are dead spaces, is generally narrow, making it difficult for a worker to directly enter the block unit (115) and thus difficult to perform painting work, and thus difficult to form a painted surface.

[0026] The block unit (115) generally forms a dead space where it is difficult for a worker to work due to the narrow space, and forms a dry space where there is no seawater influence, so condensation may occur due to the temperature difference between the inside and outside of the hull (110) in a low-temperature environment, such as in winter. However, in this embodiment, the first space (110S1) and the second space (110S2) forming the dead space can be filled with a filling part (150) so that they do not come into contact with air, thereby preventing condensation and corrosion problems.

[0027] In the block unit (115) of the present embodiment, a through hole (not shown) may be formed on one side so that a filling part (150) can be injected, and the through hole may be closed due to the injection of the filling part (150).

[0028] The filling portion (150) is configured to fill the first space (110S1) and the second space (110S2), and may be made of a foam (e.g., urethane material, plastic composite), but in order to improve the strength of the hull (110), it may be provided as cement (concrete) and then filled into the block unit (115) and hardened to enable reinforcement of the block unit (115) and its surroundings.

[0029] Since the strength of the block unit (115) can be improved by the filling portion (150) provided with cement, the longitudinals and stiffeners provided as reinforcing structures in the hull (110) area other than the block unit (115) may be omitted, and the amount of welding work for the reinforcing structure inside the block unit (115) may be reduced. However, since this is merely one embodiment, various variations are possible, such as the filling portion (150) being filled while reinforcing structures such as longitudinals and stiffeners are provided inside the block unit (115).

[0030] In addition, the filling part (150) provided with cement is injected into the block unit (115) with fast-drying cement, and then hardened after removing foam so that there are no empty parts in the first space (110S1) and the second space (110S2), so that the block unit (115) can be completely filled with cement.

[0031] The block unit (115) filled with cement forms a structure that is filled rather than empty, so even if a mooring line is caught, the strength is higher than that of a standard hull (110), and the risk of damage can be reduced.

[0032] In the vessel (100) according to this embodiment, even if a dead space such as the first space (110S1), which is the upper space of the bulb (111) where it is difficult to form a painted surface, and the second space (110S2), which is the upper space of the propeller (140), is not formed with a painted surface, it can be filled with a filling part (150) such as cement to prevent condensation and corrosion, and reinforcement by cement can be achieved.

[0033] Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention may be implemented in other specific forms without changing its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. Explanation of the symbols
