Mode for Carrying Out the Invention

[0008] (First Embodiment) FIG. 1 is a configuration diagram showing the configuration of a ship 30 according to the first embodiment of the present invention. FIG. 2 is a perspective view of the upper structure 10 according to the present embodiment as seen from the bow side. FIG. 3 is a perspective view of the upper structure 10 according to the present embodiment as seen from the stern side. In the drawings, the same parts are denoted by the same reference numerals, and duplicate explanations are omitted as appropriate. <00001百所>

[0009] The ship 30 includes a hull 20 and an upper structure 10. The upper structure 10 is provided on the deck located on the upper surface of the hull 20. In FIG. 1, the upper structure 10 is provided on the stern side, but it may be provided on the bow side or near the center. Here, the upper structure 10 is mainly described as a bridge, but any structure provided on the upper surface of the hull 20 may be used, not limited to a bridge.

[0010] The superstructure 10 comprises a main body 11, two wings 12a, 12b, two front legs 13a, 13b, two rear legs 14a, 14b, and a number of appendages 1, 2, 3.

[0011] The main body section 11 is the central part of the superstructure 10. The lower part of the main body section 11 is roughly the shape of a flat rectangular prism. The upper part of the main body section 11 has a shape on which various structures are attached, with the lower part serving as the base. For example, the main body section 11 is equipped with living quarters, a command center for steering the ship, support columns for wings 12a and 12b, and a funnel, etc.

[0012] Wings 12a and 12b are shaped to extend from the upper part of the main body 11 in the left and right directions, respectively. The right wing 12a is provided on the starboard side of the main body 11. The left wing 12b is provided on the port side of the main body 11.

[0013] The forelegs 13a and 13b are members that extend vertically downward from beneath each wing 12a and 12b toward the deck. The forelegs 13a and 13b serve to support each wing 12a and 12b. The right forelegs 13a is attached to the right wing 12a. The left forelegs 13b is attached to the left wing 12b.

[0014] The rear legs 14a and 14b are members that extend diagonally downward and rearward from beneath each wing 12a and 12b toward the deck. The upper ends of the rear legs 14a and 14b are integrally connected to the upper ends of each front leg 13a and 13b. The lower ends of the rear legs 14a and 14b are located aft of the points where the lower ends of each front leg 13a and 13b are installed on the deck, and are installed on the deck. The rear legs 14a and 14b, together with each front leg 13a and 13b, support each wing 12a and 12b. The right rear leg 14a is provided on the right wing 12a. The left rear leg 14b is provided on the left wing 12b. Each rear leg 14a and 14b may be connected to the corresponding front leg 13a and 13b by support members or the like to increase strength.

[0015] The appendages 1 to 3 are attached to predetermined locations on the superstructure 10. The appendages 1 to 3 are shaped to reduce wind resistance that would hinder the navigation of the vessel 30. Each appendage 1 to 3 has a different shape. The appendage 1 to 3 to be attached is determined by the location where it will be attached. The appendages 1 to 3 are, for example, made of fiber-reinforced plastic (FRP), and may have a filler such as polyurethane foam injected inside. However, the appendages 1 to 3 are not limited to these materials and may be made of any material such as metal or resin.

[0016] The shapes of appendages 1 to 3 will be described with reference to Figures 4 to 6. Figure 4 is a perspective view showing the shape of the first appendage 1. Figure 5 is a perspective view showing the shape of the second appendage 2. Figure 6 is a perspective view showing the shape of the third appendage 3. The units of length shown in the figures are millimeters.

[0017] Here, specific lengths are given for explanation, but these lengths are for reference only and can be changed to any length according to the installation location, etc. For example, the length of each attachment 1 to 3 in the direction in which they are lined up (height from the bottom to the top) can be any value. Also, the lengths of attachments 1 to 3 may be determined to be easy to handle. Here, the length in the longitudinal direction of the installation location is standardized to 1000 mm for all attachments. This is an example of a size that assumes installation on a ship without the use of heavy machinery. To allow attachments 1 to 3 to be carried by hand without the use of heavy machinery, the maximum length of one side (height, width, or depth) of attachments 1 to 3 should preferably be 3 m or less. Multiple attachments 1 to 3 are installed in close proximity according to the length of the installation location. Alternatively, instead of installing multiple attachments 1 to 3 side by side, one or fewer attachments that combine multiple attachments 1 to 3 into a single unit, tailored to the installation location, may be installed.

[0018] The first appendage 1 is columnar, and its cross-section (the top and bottom surfaces are the same shape) is close to a sector shape. More specifically, the cross-section is a curved hypotenuse of a right triangle formed by two sides of different lengths. The first appendage 1 has three sides: two planes that are perpendicular to each other, and one curved surface adjacent to these two planes. For example, the first appendage 1 has a columnar height of 1000 mm, and one of the two sides forming the right angle in the cross-section is 500 mm long, while the other side is 466 mm long.

[0019] The second appendage 2 is columnar, and its cross-section (the top and bottom surfaces are the same shape) is shaped like a rounded corner formed by two equal sides of an isosceles triangle. The second appendage 2 has three planes as sides, and the corner where the two sides corresponding to the two equal sides of the cross-section meet is rounded to form a curved surface. For example, the second appendage 2 has a columnar height of 1000 mm, a base length that is not equal to the other two sides of the cross-section of 2000 mm, and a height of 1000 mm from the base of the cross-section to the vertex corresponding to the corner where the two equal sides meet. Here, the cross-section is shown to be close to a right-angled isosceles triangle, but the angle formed by the two equal sides is not limited to a right angle; it may also be acute or obtuse.

[0020] The third appendage 3 is columnar, and its cross-section (the top and bottom surfaces are the same shape) is a convex shape that protrudes in a quadratic curve relative to the straight base. The third appendage 3 has two sides: one flat surface and one curved surface that protrudes in a convex shape. For example, the third appendage 3 has a columnar height of 1000 mm, a straight cross-sectional length (base) of 850 mm, and a height of 1000 mm for the protruding convex shape of the cross-section.

[0021] Furthermore, any curved surface included in appendages 1 to 3 may have any shape (e.g., any curvature) as long as it allows wind to flow smoothly over the surface. Similarly, any convex shape that receives wind included in appendages 1 to 3 may have any shape (e.g., height) as long as it allows wind to flow smoothly over the surface. The shape of any curved surface or convex shape in appendages 1 to 3 can be determined to further reduce wind resistance in accordance with the actual configuration of the ship 30.

[0022] Next, the method of attaching attachments 1 to 3 will be explained. Figure 7 is a perspective view showing the third attachment 3 attached to the right foreleg 13a and right hind leg 14a. Figure 8 is a perspective view showing the third attachment 3 attached to the left foreleg 13b and left hind leg 14b.

[0023] The first appendage 1 is provided at the corners of the front of the left and right sides adjacent to the front (bow) of the main body 11. The first appendage 1 is attached so that the longer side (500 mm in Figure 4) is in close contact with the side of the main body 11, and the curved side is located on the front and outward. Multiple first appendages 1 are arranged so that the vertical direction is the longitudinal direction, and the top and bottom surfaces of two adjacent first appendages 1 are in close contact. As a result, a curved portion including a curved shape that is bent from the front to the side is formed vertically at the corners of the sides of the main body 11. By providing the first appendage 1, wind received on the front of the main body 11 from the front flows backward along the curved surface of the first appendage 1, thereby reducing wind resistance.

[0024] The second appendage 2 is provided on each wing 12a, 12b. The second appendage 2 is attached with its longest planar side (2000 mm in Figure 5) in close contact with the front of the wings 12a, 12b, and its curved apex extending horizontally (in the longitudinal direction of the wings 12a, 12b). As a result, the front of the wings 12a, 12b has a shape in which the curved apex of the second appendage 2 protrudes. Multiple second appendages 2 are arranged so that the horizontal direction is the longitudinal direction, and the top and bottom surfaces of two adjacent second appendages 2 are in close contact. By providing the second appendage 2, the wind received by the wings 12a, 12b from the front flows backward along the shape of the second appendage 2, thereby reducing wind pressure.

[0025] The third appendage 3 is provided on the front (bow side) of the front legs 13a, 13b and on the rear (stern side) of the rear legs 14a, 14b, respectively. The planar side of the third appendage 3 is attached in close contact with the front of the front legs 13a, 13b or the rear of the rear legs 14a, 14b, with the apex of the curved surface extending in the longitudinal direction of the front legs 13a, 13b or the rear legs 14a, 14b. As a result, the front of the front legs 13a, 13b or the rear of the rear legs 14a, 14b will have a shape in which the apex of the curved surface of the third appendage 3 protrudes. Multiple third appendages 3 are arranged in the longitudinal direction of the legs 13a, 13b, 14a, 14b, and attached so that the top and bottom surfaces of two adjacent third appendages 3 are in close contact. By providing the third appendage 3, the wind received by the front legs 13a, 13b and rear legs 14a, 14b from the front flows backward along the curved surface of the third appendage 3, thereby reducing wind pressure.

[0026] Referring to Figures 9 to 12, the wind pressure resistance of the superstructure 10 due to appendages 1 to 3 will be explained. Figures 9 to 12 are analytical diagrams showing the results of an analysis in which wind is applied to the superstructure 10 from the front. The lines in the figures represent streamlines indicating the flow of the wind.

[0027] Figures 9 and 11 show the left wing 12b as viewed from the port side. In Figure 9, the second appendage 2 is not attached, while in Figure 11, the second appendage 2 is attached. Comparing Figures 9 and 11, in Figure 11, the streamlines hitting the second appendage 2 flow more smoothly behind the left wing 12b. This indicates that the wind resistance hitting the left wing 12b is reduced by the second appendage 2.

[0028] Figures 10 and 12 are top views of the lower port side portion of the superstructure 10. In Figure 10, the first appendage 1 and the third appendage 3 are not attached, while in Figure 12, the first appendage 1 and the third appendage 3 are attached. Comparing Figure 10 and Figure 12, the streamlines flowing from the front in Figure 12 do not bulge outwards (towards the port side). This indicates that the wind resistance on the underside of the superstructure 10 is reduced by the first appendage 1 and the third appendage 3.

[0029] According to this embodiment, by attaching appendages 1 to 3, which are shaped to reduce wind pressure resistance, to the main body portion 11, the wings 12a and 12b, and the legs 13a, 13b, 14a, and 14b that support the wings 12a and 12b, the wind pressure resistance of the superstructure 10 of the ship 30 can be reduced.

[0030] In this description, attachments 1 to 3 are described as being attached later. However, the object to which attachments 1 to 3 are attached (main body 11, wings 12a, 12b, or legs 13a, 13b, 14a, 14b) may be integrally formed with attachments 1 to 3, or this object may be formed to have a shape equivalent to that of the object with attachments 1 to 3 attached.

[0031] Furthermore, the third appendage 3 may not be provided, or it may be provided on only one of the front legs 13a, 13b or the rear legs 14a, 14b. In this case as well, the wind pressure resistance of the superstructure 10 can be reduced by providing the first appendage 1 and the second appendage 2. In addition, although a configuration in which the superstructure 10 is provided with front legs 13a, 13b and rear legs 14a, 14b has been described, the rear legs 14a, 14b may not be provided, or there may be no legs at all.

[0032] (Second Embodiment) Figure 13 is a perspective view of the superstructure 10A according to the second embodiment of the present invention, viewed from the bow side. Figure 14 is a perspective view of the superstructure 10A according to this embodiment, viewed from the stern side.

[0033] The superstructure 10A is the superstructure 10 according to the first embodiment, with the addition of a second appendage 2A and a third appendage 3A, which are modified versions of the second appendage 2 and the third appendage 3, respectively. Other aspects are the same as in the first embodiment.

[0034] The shapes of the second appendage 2A and the third appendage 3A will be described with reference to Figures 15 and 16. Figure 15 is a perspective view showing the shape of the second appendage 2A. Figure 16 is a perspective view showing the shape of the third appendage 3A.

[0035] The second appendage 2A, in the second appendage 2 according to the first embodiment shown in Figure 5, transforms the two sides (planes) corresponding to the two equal sides of the isosceles triangle of the columnar cross-section into two curved surfaces of different shapes. Specifically, both of these curved surfaces are smooth without irregularities, but they have different angles of inclination. Here, the angle of inclination of a curved surface is the angle formed between this plane and the side (plane) corresponding to the base of the cross-section when this curved surface is turned into a plane. For example, the second appendage 2A has a columnar height of 1000 mm, a base length of 2000 mm, and a height of 995 mm from the base of the cross-section to the vertex where the two curves (lines corresponding to the two curved surfaces) meet.

[0036] The third appendage 3A differs from the third appendage 3 according to the first embodiment shown in Figure 6 in that it has a different shape for the columnar curved surface. Specifically, the shape of the curved surface is different on the left and right sides, separated by the apex of the curved surface. Both of these curved surfaces are smooth without irregularities, but they have different angles of inclination. The angle of inclination of the curved surface is the same as that of the second appendage 2A described above. For example, the third appendage 3A has a columnar height of 1000 mm, a base length of 850 mm, and a height from the base to the apex of the cross-section of 1000 mm.

[0037] Next, the method of attaching the second appendage 2A and the third appendage 3A will be described. Figure 17 is a perspective view showing the third appendage 3A attached to the right front leg 13a and the right rear leg 14a. Figure 18 is a perspective view showing the third appendage 3A attached to the left front leg 13b and the left rear leg 14b. Figure 19 is a perspective view showing the second appendage 2A attached to the left wing 12b. The first appendage 1 is attached in the same manner as in the first embodiment.

[0038] The second appendage 2A is provided on each wing 12a, 12b. The second appendage 2A is attached so that its curved apex portion faces downwards. In other respects, the second appendage 2A is attached in the same manner as the second appendage 2 in the first embodiment.

[0039] The third appendage 3A is provided on the front surfaces of the front legs 13a and 13b, and on the rear surfaces of the rear legs 14a and 14b, respectively. The third appendage 3A is attached to the front legs 13a and 13b so that the apex where the two curved surfaces meet faces the inside of the ship (towards the main body 11). The third appendage 3A is attached to the rear legs 14a and 14b so that the apex where the two curved surfaces meet faces the outside of the ship (opposite side from the main body 11). In other respects, the third appendage 3A is attached in the same manner as the third appendage 3 in the first embodiment.

[0040] Referring to Figures 20 and 21, the wind resistance of the superstructure 10A due to the second appendage 2A and the third appendage 3A will be explained. Figures 20 and 21 are analytical diagrams obtained by applying wind from the front to the superstructure 10A, similar to Figures 9 to 12. The lines in the figures represent streamlines indicating the flow of wind. Figure 20 is a view of the left wing 12b from the port side. Figure 21 is a view from above of the lower port side portion of the superstructure 10A.

[0041] As shown in Figure 20, the streamlines that strike the second appendage 2A flow smoothly behind the left wing 12b. Compared with Figure 11, this shows that the second appendage 2A in this embodiment reduces wind pressure resistance more effectively than the second appendage 2 in the first embodiment.

[0042] As shown in Figure 21, the streamlines flowing from the front flow smoothly to the rear without bulging outwards. Compared with Figure 12, the third appendage 3A in this embodiment reduces wind pressure resistance more effectively than the third appendage 3 in the first embodiment.

[0043] According to this embodiment, by providing the second appendage 2A and the third appendage 3A instead of the second appendage 2 and the third appendage 3 in the first embodiment, the wind pressure resistance of the superstructure 10A of the ship 30 can be reduced compared to the first embodiment.

[0044] (Third embodiment) Figure 22 is a perspective view of the superstructure 10B according to the third embodiment of the present invention, viewed from the bow side. Figure 23 is a perspective view of the superstructure 10B according to this embodiment, viewed from the stern side.

[0045] The superstructure 10B is provided in the superstructure 10A of the second embodiment by adding a third appendage 3A to the corner portion of the rear surface facing the rear (stern side) of the main body portion 11. Other aspects are the same as in the second embodiment.

[0046] The third appendage 3A is attached to the corner portion that protrudes outward from the rear surface of the lower part of the superstructure 10B, and to the corner portion that protrudes outward from the rear surface of the structure provided on the upper side of the superstructure 10B. Appendages 1, 2A, and 3A are attached to the other parts of the superstructure 10B, similar to the second embodiment.

[0047] Furthermore, if the superstructure 10B includes multiple structures, the third appendage 3A does not necessarily have to be attached to the rear surface of all structures. Also, if one structure of the superstructure 10B has multiple rear surfaces, the third appendage 3A is provided on the corner portions that protrude outward from these rear surfaces, but the third appendage 3A does not have to be provided on some of these corner portions.

[0048] Next, the method for attaching the third appendage 3A to the corner portion of the rear surface of the main body portion 11 will be described. Figure 24 is a perspective view showing the third appendage 3A attached to a corner portion extending in the vertical direction. Figure 25 is a perspective view showing the third appendage 3A attached to a corner portion extending in the horizontal direction.

[0049] At vertically extending corner sections, the third appendage 3A is attached so that the vertex where the two curved surfaces meet extends vertically, and the vertex faces outwards (starboard side if it is a starboard corner section, and port side if it is a port corner section).

[0050] At the horizontally extending corner section, the third appendage 3A is attached so that the vertex where the two curved surfaces meet extends horizontally, with the vertex facing upwards.

[0051] According to this embodiment, by providing the superstructure 10B with a third appendage 3A added to the corner portion of the rear surface of the superstructure 10A according to the second embodiment, the wind pressure resistance of the superstructure 10B can be reduced compared to the second embodiment.

[0052] In addition, instead of the third appendage 3A according to the second embodiment, the third appendage 3 according to the first embodiment may be added to the superstructure 10A according to the second embodiment, or an appendage of other shapes may be added. Furthermore, in each embodiment, an appendage of any shape may be added to reduce wind pressure resistance.

[0053] The present invention is not limited to the embodiments described above, and components may be deleted, added, or modified. Furthermore, new embodiments may be created by combining or replacing components in multiple embodiments. Even if such embodiments differ directly from the embodiments described above, those that share a similar purpose to the present invention are described as embodiments of the present invention, and their descriptions are omitted.
