Description

A ship equipped with a bow navigation section

[0001] The present invention relates to a bow navigation section and a ship equipped with the same, and more specifically, to a ship equipped with a bow navigation section that can effectively reduce air resistance on the bow side while facilitating forward visibility by positioning the navigation section, which was previously provided in the ship's accommodation area, at the bow side and forming it with an air resistance reduction structure.

[0002] Generally, container ships operate by loading multiple containers in the cargo holds inside the hull and on the upper deck above the hull.

[0003] Figure 1 illustrates a ship according to the prior art.

[0004] Referring to FIG. 1, in order to maximize cargo loading capacity, a container ship (1) can load multiple containers (c) in the space excluding the living quarters (2) where crew members reside on the upper deck of the hull and the engine casing (4) which is equipped with a funnel for exhaust gas discharge.

[0005] Additionally, since green water may flow into the foremost part of the bow during ship operation, making it difficult to load containers, the space may be formed as an empty space, or a breakwater structure (not shown) to block the green water may be installed, and a container (c) may be loaded behind the breakwater structure (not shown).

[0006] In the case of such a container ship (1), there is a problem that air resistance is significantly affected because the wind load area is widened as containers (c) are loaded high on the bow side, and there is also a problem that the breakwater structure (not shown) acts as a factor in air resistance.

[0007] In this case, when a ship encounters air resistance, it must burn more fuel to generate energy for operation, which increases fuel consumption, reduces speed, and can deteriorate maneuverability.

[0008] In addition, in the case of a conventional container ship (1), the accommodation area (2) is located in the middle section of the ship or in a position close to the bow section in the middle section, and since a wheelhouse (3) for steering the ship is provided at the top of the accommodation area (2), there was a problem that the loading height of the container (c) in the bow section had to be limited in order to secure a view of the wheelhouse (3).

[0009] In addition, the navigation section (3) is separated from the bow section, so even if the front is checked through the navigation section (3), there is a problem that there is a blind spot in the view at the tip of the bow section and in front of it.

[0010] The present invention aims to provide a vessel equipped with a bow navigation section, specifically a vessel in which the navigation section, which was previously located above the accommodation area, is positioned at the bow end and formed into an air resistance reduction structure in the form of a spoiler, thereby facilitating forward visibility of the navigation section while effectively reducing air resistance on the bow side.

[0011] The technical problems to be solved by the present invention are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which the present invention belongs from the description below.

[0012] To solve the problem described above, the present invention provides a vessel having a bow navigation section comprising accommodation provided in the hull and a navigation section provided in the bow of the hull to secure a forward view, the front of which is formed to be inclined toward the rear to reduce air resistance on the bow side.

[0013] Additionally, the vessel provides a bow navigation section comprising an upper section equipped with a navigation room for steering the vessel and a lower section provided in the bow of the hull to support the upper section, equipped with mooring equipment inside, and having an opening formed in a structure that can be opened and closed so as to expose the mooring equipment.

[0014] In addition, the vessel has a bow section that further includes a middle section provided between the upper and lower sections, and in which an equipment space or a living space is formed.

[0015] In addition, the vessel provides a bow navigation section comprising a navigation section that is provided at the lower end, supports the lower part of the middle section, and further includes a lifting section that raises and lowers the middle section and the upper section which are integrally provided.

[0016] Additionally, the vessel provides a bow section having a wind turbine installed inside the middle section and a door that can be opened and closed formed at the front, wherein, during vessel operation, the door is opened to open the front of the middle section to allow wind to flow in and operate the wind turbine, and the wind flowing in is discharged through an outlet formed at the rear.

[0017] In addition, the vessel provides a middle section formed of multiple layers and a bow navigation section formed with an equipment space for installing an air conditioner and a bow accommodation area for crew members.

[0018] In addition, the present invention provides a vessel having a bow navigation unit further comprising a digital navigation unit equipped in the accommodation area and providing a forward image transmitted from the navigation unit to be displayed on a screen.

[0019] In addition, the ship has a bow navigation section that includes a camera section for photographing the front of the hull, and a digital navigation section that includes a display section for providing the forward image captured by the camera section as a screen.

[0020] In addition, the digital navigation unit analyzes forward images and transmits information to the navigation unit to assist in navigation, and provides a vessel equipped with a bow navigation unit that includes a ship steering means and can replace the functions of the navigation unit in an emergency.

[0021] Additionally, the vessel further comprises a cargo tank formed within the hull with its upper portion protruding above the hull, and a navigation section formed at a height corresponding to the height of the upper portion of the cargo tank, and a bow navigation section having a rear end connected to the front end of the cargo tank protruding above the hull.

[0022] In addition, the vessel is provided with a bow section having a passage formed at the connection point between the navigation section and the cargo tank, which allows movement between the cargo tank and the navigation section.

[0023] Additionally, the vessel further includes an engine casing provided in the stern of the hull, and the accommodation area is formed with a height lowered by the amount by which the navigation section provided at the top is removed as the navigation section is moved and positioned in the bow, and the engine casing is provided with a bow navigation section formed in correspondence with the lowered height of the accommodation area.

[0024] In addition, the present invention provides a vessel having a bow section that further includes an air resistance reduction device that is foldably provided on the top of the engine casing and accommodation area or the engine casing provided in the stern of the hull and unfolds as needed to reduce air resistance.

[0025] Additionally, the air resistance reduction device provides a vessel having a bow operating section comprising: a frame portion foldably provided on the top of the accommodation area or engine casing; a shield member connected to the frame portion in the form of a tent and formed so as to reduce air resistance by having its front surface inclined toward the rear when the frame portion is unfolded; and an operating section that operates to unfold or fold the frame portion.

[0026] Additionally, the air resistance reduction device provides a vessel having a bow operating section comprising a frame portion foldably provided on the top of the accommodation area or engine casing, a plurality of air nozzles provided on the frame portion that spray air to form an air curtain, an air supply portion that supplies air to the air nozzles, and an operating portion that operates the frame portion to unfold or fold.

[0027] A vessel equipped with a bow navigation section according to an embodiment of the present invention can effectively reduce air resistance on the bow side while facilitating forward visibility of the navigation section by positioning the navigation section, which was previously provided at the top of the accommodation area, at the bow end and forming the navigation section in the form of a spoiler-shaped air resistance reduction structure.

[0028] In addition, by separating the navigation section from the accommodation section and positioning it at the bow, the height of the accommodation section located at the stern can be lowered. As the height of the accommodation section is lowered, the height of the engine casing can also be lowered, thereby significantly reducing air resistance caused by the accommodation section and the engine casing compared to conventional vessels.

[0029] In addition, the navigation section provided in the bow section includes an upper section equipped with a navigation room, a middle section with additional space formed for various uses, and a lower section with mooring equipment installed, wherein an opening with an opening and closing structure is formed in the lower section to facilitate mooring operations through the mooring equipment.

[0030] In addition, a digital navigation unit may be additionally provided in the accommodation area located at the stern, and by outputting the forward image transmitted from the bow navigation unit through a display unit, safety can be significantly increased due to the additional visibility during ship operation.

[0031] The effects obtainable from the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description below.

[0038] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings.

[0039] The detailed description disclosed below, together with the attached drawings, is intended to describe exemplary embodiments of the present invention and is not intended to represent the only embodiment in which the present invention can be practiced.

[0040] In order to clearly explain the invention in the drawings, parts unrelated to the explanation may be omitted, and the same reference numerals may be used for identical or similar components throughout the specification.

[0041] In embodiments of the present invention, expressions such as “or”, “at least one”, etc. may represent one of the words listed together or a combination of two or more.

[0042] FIGS. 2 to 5 illustrate ships equipped with a bow navigation section according to an embodiment of the present invention, categorized by ship type.

[0043] A ship having a forward navigation section according to an embodiment of the present invention can be formed such that the navigation section, which was previously located at the top of the ship's accommodation area, is positioned at the bow side, and the navigation section (200) is formed with an air resistance reduction structure, thereby facilitating forward visibility and effectively reducing air resistance at the bow side. Additionally, by separating the navigation section from the accommodation area and positioning it at the bow side, the height of the accommodation area (110) and the engine casing (120) can be lowered, so that it is formed to be affected by air resistance as little as possible.

[0044] Referring to FIGS. 2 to 5, a ship having a sailing section according to one embodiment of the present invention may include a living quarters (110), an engine casing (120), and a sailing section (200).

[0045] FIGS. 2 and FIGS. 3 illustrate a container ship (10) according to an embodiment of the present invention, wherein the container ship (10) can operate by loading a plurality of containers (c) in a cargo hold inside the hull and on an upper deck above the hull.

[0046] In order to maximize cargo loading capacity, a plurality of containers (c) can be loaded on the upper deck of the hull, excluding the space for the crew to reside in (110) and the engine casing (120) which is equipped with a funnel for exhaust gas discharge.

[0047] In the case of a conventional container ship, the engine casing is located at the stern of the vessel, and the accommodation area is located in the middle section near the bow. Since a wheelhouse for steering the vessel is provided on top of the accommodation area, the height of containers loaded at the bow is limited to ensure visibility for the wheelhouse.

[0048] In addition, breakwater structures to block green water and protect containers and the hull structure may be installed at the foremost end of the bow.

[0049] At this time, referring to FIG. 2, the container ship (10) of the present embodiment separates the navigation section that was provided at the top of the accommodation area (110) and places it at the foremost end of the bow, and forms the navigation section (200) with an air resistance reduction structure to facilitate forward visibility, thereby removing the height limit on containers loaded in the bow section to ensure visibility of the navigation section, so that containers (c) can be loaded to the maximum extent in the bow section.

[0050] Additionally, as the navigation section (200) is moved toward the bow, the size of the accommodation area (110) can be reduced, so the accommodation area (110) can be integrated with the engine casing (120) and placed in the stern section, and thereby additionally, a container (c) can be loaded in the space where the accommodation area (110) was previously located, thereby increasing the loading capacity of the container (c).

[0051] Furthermore, since the height of the accommodation area (110) can be lowered as much as the navigation section is removed, even if the funnel of the engine casing (120) is placed on the upper part of the accommodation area (110), the integrated structure of the accommodation area (110) and the engine casing (120) can be formed at a height corresponding to the loading height of the container (c) loaded around it, thereby minimizing the effect of air resistance during ship operation.

[0052] In addition, the navigation section (200) positioned at the foremost end of the bow is formed with an air resistance reduction structure, such as a spoiler shape with the front inclined toward the rear, so that it can block and disperse green water while reducing air resistance on the bow side, and a space for accommodating mooring equipment can be formed at the bottom.

[0053] Additionally, referring to FIG. 3, the navigation unit (200) is formed to be height-adjustable in correspondence with the loading height of the container (c) positioned at the rear, thereby effectively reducing air resistance acting on the bow side.

[0054] In addition, various additional spaces may be formed inside the operation section (200) in addition to the operation room, and a detailed explanation thereof will be provided later.

[0055] FIG. 4 illustrates a liquefied natural gas carrier (20) according to one embodiment of the present invention, wherein the liquefied natural gas carrier (20) may be equipped with a plurality of cargo tanks (21) for storing and transporting liquefied natural gas (LNG) inside the hull.

[0056] At this time, the cargo tank (21) can be formed with its upper part protruding above the hull to secure sufficient internal storage space, and as an example, the upper part of the cargo tank (21) can be formed to protrude approximately 5 to 15 m from the upper deck of the hull.

[0057] In the case of a conventional liquefied natural gas carrier, accommodations and an engine casing are arranged in the stern of the vessel. Depending on the hull shape, accommodations may be arranged in the stern and an engine casing may be arranged behind the accommodations, or accommodations may be arranged in the stern and an engine casing may be arranged above the accommodations, and a navigation section may be provided on top of the accommodations.

[0058] Here, the accommodation area is formed higher than the cargo tank protruding above the hull to ensure visibility from the navigation section located at the top, and the engine casing emitting exhaust gases is formed higher than the accommodation area, which can act as a factor increasing air resistance during ship operation, and as the navigation section is positioned at the stern, a blind spot in visibility occurs at the tip of the bow and in front of it.

[0059] At this time, referring to FIG. 4, the liquefied natural gas carrier (20) of the present embodiment can easily secure a forward view without blind spots by separating the navigation section, which was provided at the top of the accommodation area, and positioning it at the very front of the bow. The navigation section (200) is formed with an air resistance reduction structure, such as a spoiler shape with a slanted front, so that it can block and disperse green water while reducing air resistance on the bow side.

[0060] At this time, the navigation section (200) positioned in the bow section can be formed at a height corresponding to the height of the cargo tank (21) protruding from the upper part of the hull so as to effectively reduce air resistance.

[0061] Additionally, the height of the accommodation area (110) can be lowered by the amount of the operating part removed, and as the height of the accommodation area (110) is lowered, the height of the engine casing (120) can also be lowered, so that the air resistance caused by the accommodation area (110) and the engine casing (120) can be greatly reduced compared to the existing one.

[0062] For example, the engine casing (120) can be formed higher than the accommodation area (110) because it emits exhaust gas. In this embodiment, in the case of a ship in which the accommodation area (110) and the engine casing (120) are each provided at the stern, the height of the engine casing (120) can be lowered by the amount of the lowered height of the accommodation area (110) because there is no influence of exhaust gas on the accommodation area (110).

[0063] In addition, in the case of a ship in which an engine casing (120) is provided on the upper part of the accommodation area (110), the engine casing (120) can be lowered by the lowered height of the accommodation area (110), thereby reducing air resistance caused by the accommodation area (110) and the engine casing (120).

[0064] FIG. 5 illustrates a liquid hydrogen carrier (30) according to one embodiment of the present invention, wherein the liquid hydrogen carrier (30) may be equipped with a plurality of cargo tanks (31) for storing and transporting liquid hydrogen (LH2) inside the hull.

[0065] At this time, the cargo tank (31) can be formed with its upper part protruding above the hull to secure sufficient internal storage space. Since the specific gravity of liquefied hydrogen is approximately 1 / 6 to 1 / 7 lower than that of liquefied natural gas and the evaporation rate per volume is higher than that of liquefied natural gas, the height of the cargo tank (31) can be formed to be similar or higher than that of the cargo tank (21) of the liquefied natural gas carrier (20) described above.

[0066] As an example, the upper part of the cargo tank (31) protruding above the hull of the liquefied hydrogen carrier (30) of the present embodiment may be formed to protrude approximately 9 to 30 m from the upper deck of the hull.

[0067] Even in the case of conventional liquefied hydrogen carriers, the accommodation area and engine casing are located at the stern of the vessel. The accommodation area is positioned higher than the cargo tanks protruding above the hull to ensure visibility from the navigation section, and the engine casing, which emits exhaust gases, is positioned higher than the accommodation area. This can act as a factor that increases air resistance during operation, and as the navigation section is located at the stern, a blind spot in visibility occurs at the tip of the bow and in front of it.

[0068] At this time, referring to FIG. 5, the liquefied hydrogen carrier (30) of the present embodiment can easily secure a forward view without blind spots by separating the navigation section that was provided at the top of the accommodation area (110) and placing it at the foremost end of the bow, and since the navigation section (200) is formed with an air resistance reduction structure, air resistance on the bow can be reduced, and green water flowing into the bow can also be blocked and dispersed.

[0069] At this time, the navigation section (200) positioned in the bow section can be formed at a height corresponding to the height of the cargo tank (31) protruding from the upper part of the hull.

[0070] In addition, as previously explained, the height of the accommodation area (110) can be lowered by the amount of the operating part removed, and the height of the engine casing (120) can be lowered by the amount of the height of the accommodation area (110), so that the air resistance caused by the accommodation area (110) and the engine casing (120) can be significantly reduced compared to the existing one.

[0071] FIGS. 6 to 13 illustrate various examples of a navigation unit (200) according to one embodiment of the present invention.

[0072] Referring to FIGS. 6 to 13, a navigation unit (200) according to one embodiment of the present invention is positioned at the bow end of the hull and can be formed in the shape of a spoiler with a curved front and side slopes to effectively reduce air resistance.

[0073] Such a navigation section (200) may be formed in a shape including an upper section (210), a middle section (220), and a lower section (230), or may be formed in a shape including an upper section (210) and a lower section (230).

[0074] For example, referring to FIG. 6, the operating section (200) may be formed in a shape including an upper section (210), a middle section (220), and a lower section (230). The upper section (210) is equipped with an operating room, and the middle section (220) between the upper section (210) and the lower section (230) is formed in a spoiler shape together with the upper section (210). The internal space may be utilized as an equipment space where a generator or air conditioner is installed, or as a convenience space or living space for crew members.

[0075] Additionally, the lower part (230) is formed as a support structure that supports the upper part (210) and the middle part (220), mooring equipment is installed in the internal space, and an opening of an opening structure that allows the rope of the mooring equipment to be exposed can be formed on the outer wall of the lower part (230).

[0076] That is, mooring equipment is provided in the inner space of the lower part (230), so that when mooring a ship, a plurality of openings formed in the lower part (230) are opened and the ropes of the mooring equipment are extended to the outside through the openings to perform mooring work.

[0077] Additionally, the navigation section (200) may be formed with the upper section (210), middle section (220), and lower section (230) integrally in the shape of a spoiler, and the upper section (210), middle section (220), and lower section (230) of the navigation section (200) may have a passage formed connecting them to each other, so that crew members within the navigation section (200) can freely move to the upper section (210), middle section (220), and lower section (230) through the passage.

[0078] As another example, referring to FIG. 7, the navigation unit (200) of the present embodiment is structured to be easily applied to a container ship (10) and can be provided with height adjustable in correspondence with the loading height of a container (c) loaded at the rear of the navigation unit (200) from the bow side.

[0079] Specifically, the operating part (200) of the present embodiment may be provided with a lifting part (231) at the lower part (230), and the lifting part (231) supports the lower part of the middle part (220) and can lift the middle part (220) and the upper part (210) which are integrally provided.

[0080] For example, the lifting section (231) is formed with a hydraulic cylinder or the like to support the lower part of the middle section (220), and by raising the middle section (220) and the upper section (210) from the lower section (230) in correspondence with the loading height of the container (c), the operating section (200) can be adjusted to a height corresponding to the loading height of the container (c).

[0081] At this time, the gap between the middle section (220) and the lower section (230), which is formed as the middle section (220) and the upper section (210) rise from the lower section (230), can be shielded by a shielding member (not shown).

[0082] For example, a shielding member (not shown) may be connected between a middle section (220) and a lower section (230) in the form of a roll screen and formed to shield the gap space by unfolding as the middle section (220) is separated from the lower section (230), or it may be connected in a foldable manner between the middle section (220) and the lower section (230) so as to unfold between the middle section (220) and the lower section (230) to shield the gap space.

[0083] As another example, referring to FIG. 8, the navigation unit (200) of the present embodiment is a structure that can be easily applied to a container ship (10) and can be formed with a height corresponding to the maximum loading height of the container (c).

[0084] In this case, compared to the existing container ship (10), the maximum number of containers (c) can be loaded in the bow section, thereby increasing the loading capacity of the containers (c), and as the internal space of the middle section (220) is expanded by the height of the navigation section (200), the middle section (220) can be utilized as a living quarters.

[0085] At this time, as an example, if the middle section (220) of the navigation section (200) is utilized as a living quarters, the living quarters located in the existing hull can be removed, and additional containers (c) can be loaded in the location where the living quarters were removed, so the loading capacity of containers (c) can be greatly increased.

[0086] Meanwhile, in the case of the container ship (10) described above, a front-to-back separation space (s) is required between the operating section (200) and the container (c) placed behind it. Since the vibration ranges of the operating section (200) fixed to the hull and the container (c) loaded on the hull are different, damage may occur if the container (c) is connected to or placed in close contact with the operating section (200). To prevent such damage, the container (c) may be placed at a predetermined distance (e.g., 100 to 200 mm) from the operating section (200).

[0087] As another example, referring to FIG. 9, the navigation unit (200) of the present embodiment may be formed to include an upper part (210) equipped with a navigation room and a lower part (230) equipped with mooring equipment.

[0088] The navigation section (200) of the present embodiment may be formed with a lower height compared to the navigation section (200) of the above-described embodiment by removing the intermediate section, and can be easily applied to a liquefied natural gas carrier (20).

[0089] For example, in the case of a liquefied natural gas carrier (20), the height of the upper part of the cargo tank (21) protruding above the hull can be formed to a height of approximately 5 to 15 m, and the navigation section (200) can be formed to a height corresponding to the height of the upper part of the cargo tank (21) protruding above the hull so as to effectively reduce air resistance on the bow side.

[0090] Additionally, the rear end of the navigation section (200) can be connected to the front end of the cargo tank (21) protruding over the hull, and a passageway (not shown) can be formed at the connection point between the navigation section (200) and the cargo tank (21).

[0091] Accordingly, the worker can move from the cargo tank (21) to the operation section (200) or easily move from the operation section (200) to the cargo tank (21) through the passageway (not shown), so the travel time can be significantly reduced and work convenience can be greatly increased.

[0092] As another example, referring to FIG. 10, the navigation section (200) of the present embodiment includes an upper section (210), a middle section (220), and a lower section (230), wherein a bow accommodation area (220a) and an auxiliary space (220b) may be formed in the middle section (220).

[0093] The navigation section (200) of the present embodiment can be easily applied to a liquid hydrogen carrier (30) or a container ship (10). For example, in the case of a liquid hydrogen carrier (30), the height of the upper part of the cargo tank (31) protruding above the hull can be formed to a height of approximately 30m, so the height of the navigation section (200) can be increased in correspondence with the height of the cargo tank (31), and as the internal space of the middle section (220) is expanded by the increased height of the navigation section (200), a bow accommodation area (220a) and an auxiliary space (220b) can be formed in the middle section (220).

[0094] Here, the auxiliary space (220b) can be used to install and operate a generator or air conditioner, or as a convenience space for the crew.

[0095] Additionally, the navigation section (200) is formed at a height corresponding to the height of the upper part of the cargo tank (31) protruding over the hull, so as to effectively reduce air resistance on the bow side, and the rear end of the navigation section (200) is connected to the front end of the cargo tank (31) protruding over the hull, and a passageway (not shown) for the convenience of movement of crew members and workers can be formed at the connection point between the navigation section (200) and the cargo tank (31).

[0096] As another example, referring to FIGS. 11 and 12, the navigation unit (200) of the present embodiment includes an upper part (210), a middle part (220), and a lower part (230), and a wind turbine (221) may be installed in the middle part (220).

[0097] Additionally, depending on the height of the navigation section (200), the middle section (220) may be formed as a multi-layered structure, and a passenger accommodation area (220a) may be additionally provided.

[0098] As an example, FIG. 12 is a plan view of the interior space of a middle section (220) in which a wind turbine (221) is installed. The middle section (220) is provided with a front that can be opened and closed through a door (not shown) so that wind can enter through the front, and a wind turbine (221) including an impeller may be provided inside the middle section (220), and an outlet may be formed on both rear sides of the middle section (220) for the wind that has entered into to exit.

[0099] Accordingly, the operating unit (200) of the present embodiment can operate a wind turbine (221) by opening the front of the middle section (220) by opening the door (not shown) when operating a ship, and can discharge the wind introduced into the interior through the discharge ports on both rear sides.

[0100] At this time, the power produced through the wind turbine (221) can be used in the navigation unit (200) as needed or supplied to various equipment within the hull.

[0101] As another example, referring to FIG. 13, the navigation section (200) of the present embodiment may have the middle section (220) and the lower section (230) formed in the shape of a spoiler, and the upper section (210) equipped with a navigation room may be formed in a shape protruding above the middle section (220).

[0102] Here, an opening with a closable structure that allows the rope of the mooring equipment to be exposed may be formed in the lower part (230).

[0103] In this way, when the operating room of the upper part (210) is formed to protrude above the upper part (220), it may be easier to secure a forward view.

[0104] As another example of the present embodiment, the navigation section may have the middle section removed, the lower section formed in the shape of a spoiler, and the upper section equipped with a navigation room formed in a shape protruding above the middle section.

[0105] It is obvious that the operating section (200) of the above-described embodiments can be selectively applied to the bow section of a container ship (10), a liquefied natural gas carrier (20), and a liquefied hydrogen carrier (30), and can also be applied to various other types of ships.

[0106] Meanwhile, FIG. 14 illustrates a navigation unit (200) formed integrally with a cargo tank (21, 31) according to one embodiment of the present invention.

[0107] Referring to FIG. 14, as shown in (a), in the case of a conventional ship, a navigation section is provided on the upper part of the accommodation area located at the stern, so a blind spot in visibility occurs at the tip of the bow and in front of it. However, as shown in (b), in this embodiment, the navigation section (200) is placed at the tip of the bow so that a forward view can be easily secured without a blind spot in visibility, and thus safety during ship operation can be greatly improved.

[0108] At this time, the navigation unit (200) is formed with a spoiler-shaped air reduction structure on its front and side, so that air resistance can be effectively reduced, and green water flowing into the bow side can be blocked and dispersed through the inclined surface formed on the front.

[0109] Additionally, the navigation unit (200) installed at the bow end of the liquefied natural gas carrier (20) or liquefied hydrogen carrier (30) is formed at a height corresponding to the height of the cargo tank (21, 31) protruding from the upper part of the hull, and can be integrally connected to the cargo tank (21, 31) at the rear end.

[0110] Here, a passageway (not shown) for the convenience of movement of crew members and workers is formed at the connection point between the operating section (200) and the cargo tank (21, 31), and additionally, a space such as a warehouse or a rest room may be formed.

[0111] FIGS. 15 and 16 illustrate a digital navigation unit (300) provided in a ship according to one embodiment of the present invention.

[0112] Referring to FIGS. 15 and 16, the vessel of the present embodiment is equipped with a digital navigation unit (300) in a living quarters (110) located at the stern, which can assist the navigation unit (200) located at the bow.

[0113] At this time, the navigation unit (200) is positioned at the bow side, and the digital navigation unit (300) is provided in the stern accommodation area (110) separated from the navigation unit (200), so that the navigation unit (200) and the digital navigation unit (300) can transmit information to each other through wired and wireless communication.

[0114] Specifically, the navigation unit (200) is equipped with a camera unit (211) and can transmit an image of the front captured through the camera unit (211) to the digital navigation unit (300), and the digital navigation unit (300) is equipped with a display unit (310) and can output the front image transmitted from the navigation unit (200) through the display unit (310).

[0115] Accordingly, the digital navigation unit (300) outputs the forward image transmitted from the bow navigation unit (200) through the display unit (310), thereby greatly increasing safety by securing additional visibility during ship operation.

[0116] Additionally, as needed, the digital navigation unit (300) can check and analyze the forward image output through the display unit (310) and transmit information to the navigation unit (200) to assist in navigation. For example, in the event of an emergency situation where the navigation unit (200) of the bow section is paralyzed due to an accident or other reasons, including a ship steering means, the digital navigation unit (300) can take over the navigation unit (200) and control the ship.

[0117] In addition, as an example, an auxiliary navigation unit may be additionally provided on the upper part of the accommodation unit (110) to be operated in duplicate with the navigation unit (200) on the bow side.

[0118] FIGS. 17 to 19 illustrate an air resistance reduction device (400) provided in a ship according to one embodiment of the present invention.

[0119] Referring to FIGS. 17 to 19, an air resistance reduction device (400) may be provided at the top of the accommodation area (110) located at the stern of the ship.

[0120] For example, in the case of a container ship (10), depending on the loading of the container (c), the upper part of the accommodation area (110) may be located higher than the container (c), and air resistance can be reduced by using an air resistance reduction device (400) provided on the upper part of the accommodation area (110).

[0121] In addition, in the case of a liquefied natural gas carrier (20) or a liquefied hydrogen carrier (30), if the upper part of the accommodation area (110) is located higher than the cargo tank (21, 31), air resistance can be reduced by using an air resistance reduction device (400) provided on the upper part of the accommodation area (110).

[0122] For example, referring to FIG. 17, the air resistance reduction device (400) is formed in the shape of a spoiler with a slanted front and is positioned at the top of the accommodation (110) toward the front of the engine casing (120) to reduce air resistance.

[0123] As another example, referring to FIG. 18, the air resistance reduction device (400) is formed to unfold into a spoiler shape at the top of the living quarters (110) or fold toward the bottom of the living quarters (110), so that it can be unfolded and used as needed.

[0124] Specifically, the air resistance reduction device (400) of the present embodiment may include a frame portion (410) that forms the frame of the air resistance reduction device (400) and is foldable, a shield member (420) that is connected to the frame portion (410) in the form of a tent and is formed in the form of a spoiler when the frame portion (410) is unfolded, and an operating portion (not shown) that operates to unfold or fold the frame portion (410).

[0125] Here, the operating part (not shown) is formed with a motor and gear structure or a cylinder structure and can operate to unfold or fold the frame part (410).

[0126] Accordingly, when the frame part (410) is unfolded through the operating part (not shown) during ship operation, the tent-shaped shield member (420) connected to the frame part (410) unfolds along the frame part (410) and can be formed in the shape of a spoiler with a slanted front, thereby reducing air resistance.

[0127] As another example, referring to FIG. 19, the air resistance reduction device (400) is foldably provided at the top of the residence (110) and can reduce air resistance by injecting air to form an air curtain.

[0128] Specifically, the air resistance reduction device (400) of the present embodiment may include a frame portion (410) that forms the frame of the air resistance reduction device (400) and is foldable, a plurality of air nozzles (430) provided on the frame portion (410) and formed to spray air, an air supply portion (not shown) that supplies air to the air nozzles (430), and an operating portion (not shown) that operates the frame portion (410) to unfold or fold.

[0129] At this time, the air nozzles (430) provided in the frame portion (410) can form an air curtain by spraying air upward and backward when the frame portion (410) is unfolded.

[0130] Accordingly, when operating a ship, the frame section (410) is unfolded through an operating section (not shown), and air is supplied to a plurality of air nozzles (430) provided in the frame section (410) through an air supply section (not shown), thereby forming an air curtain through high-pressure air sprayed from the plurality of air nozzles (430), and thereby reducing air resistance.

[0131] In addition, when the vessel is moored, the air injection can be stopped and the frame part (410) can be folded toward the floor for storage through the operating part (not shown).

[0132] In the above-described embodiment, an example in which an air resistance reduction device (400) is provided on the top of the living quarters (110) was described, but it is obvious that the air resistance reduction device (400) may also be provided on the top of the engine casing (120).

[0133] As described above, a vessel equipped with a forward navigation section according to an embodiment of the present invention can effectively reduce air resistance on the forward side while facilitating forward visibility of the navigation section (200) by positioning the navigation section, which was previously provided at the top of the accommodation area, at the bow end and forming the navigation section (200) into an air resistance reduction structure in the form of a spoiler.

[0134] In addition, by separating the navigation section from the accommodation section and positioning it at the bow, the height of the accommodation section (110) positioned at the stern can be lowered, and as the height of the accommodation section (110) is lowered, the height of the engine casing (120) can also be lowered, so that air resistance caused by the accommodation section (110) and the engine casing (120) can be significantly reduced compared to conventional ships.

[0135] Additionally, the navigation section (200) provided in the bow section includes an upper section (210) equipped with a navigation room, a middle section (220) with additional space formed for various uses, and a lower section (230) with mooring equipment installed, wherein an opening with an opening / closing structure is formed in the lower section (230) so that mooring work can be easily performed through the mooring equipment.

[0136] Additionally, a digital navigation unit (300) may be additionally provided in the accommodation unit (110) located at the stern, and the digital navigation unit (300) outputs a forward image transmitted from the bow navigation unit (200) through a display unit (310), thereby greatly increasing safety by securing additional visibility during ship operation.

[0137] The embodiments of the invention disclosed in this specification and drawings are provided merely as specific examples to facilitate the explanation of the technical content of the invention and to aid in understanding the invention, and are not intended to limit the scope of the invention.

[0138] Accordingly, the scope of the present invention should be interpreted as including all modifications or variations derived based on the technical concept of the present invention, in addition to the embodiments disclosed herein.
