Abstract

[Challenge] To minimize the reduction in the vehicle loading compartment size and prevent a decrease in the number of vehicles that can be loaded. [Solution] The ship comprises a hull having a pair of sides, multiple decks arranged vertically apart within the hull to form a vehicle loading compartment, and an exhaust system for exhausting air from the vehicle loading compartment to the outside of the hull. The exhaust system comprises an exhaust fan, which is provided in the corner between the upper deck and the side of two adjacent vertically adjacent decks, and has a fan body that rotates around an axis inclined with respect to the width direction and the vertical direction, and exhausts air from the vehicle loading compartment; and an exhaust duct that defines a discharge path for discharging the air exhausted by the exhaust fan to the outside of the hull.

Description

This disclosure pertains to vessels. Patent Document 1 discloses a vessel equipped with ventilation ducts that extend vertically from the upper deck toward multiple vehicle decks. Japanese Patent Publication No. 2023-91785 This is a side view of a vessel according to an embodiment of the present disclosure.This is a plan cross-sectional view showing an example of the arrangement of an exhaust system in a vessel according to the embodiment of this disclosure.This is a cross-sectional view of the exhaust system configuration according to the embodiment of this disclosure, as seen from the bow-stern direction.This is a cross-sectional view of the exhaust system configuration according to a modified embodiment of the present disclosure, as seen from the bow-stern direction. Hereinafter, a vessel according to the embodiment of this disclosure will be described with reference to Figures 1 to 4. (Ship composition) As shown in Figure 1, the vessel 1 of this embodiment mainly comprises a hull 2 and an exhaust system 10A. The type of vessel 1 is not limited to any particular type as long as it is capable of carrying vehicles. Examples of vessel types for vessel 1 include ferries, RORO ships (Roll-on/Roll-off ships), PCTCs (Pure Car & Truck Carriers), etc. (Hull structure) The hull 2 has a pair of side panels 3A and 3B that form its outer shell, a bottom 4, and an upper deck 5. The side panels 3A and 3B each have a pair of side platings that form the port and starboard sides, respectively. The bottom 4 has bottom platings that connect these side panels 3A and 3B. The upper deck 5 illustrated in this embodiment is a full-length deck that is exposed to the outside. A superstructure 7 containing living quarters is formed on the hull 2. Note that the arrangement and shape of structures on the upper deck 5, such as the superstructure 7 shown in Figure 1, are examples only. Figure 2 is a plan cross-sectional view showing an example of the arrangement of an exhaust system in a vessel according to the present disclosure. As shown in Figure 2, each of the pair of hull sides 3A and 3B (only hull side 3A is shown in Figure 2) is provided with a steel member 6 extending in the vertical direction Dv along the inner surface 3f facing inward in the width direction W. Multiple steel members 6 are provided at predetermined intervals in the bow-stern direction FA. The steel members 6 are reinforcing members (framework) that reinforce the hull plating of the hull sides 3A and 3B. As shown in Figure 1, the hull 2 has multiple decks 9 arranged inside, spaced apart in the vertical direction Dv. At least a portion of these multiple decks 9 are designated as vehicle decks capable of carrying vehicles. Within the hull 2, the space on each of the vehicle decks 9 is designated as a vehicle loading compartment Sc, capable of accommodating vehicles. (Exhaust system configuration) The exhaust system 10A exhausts air from the vehicle loading compartment Sc to the outside of the hull 2. The exhaust system 10A is located within the hull 2, along either the side 3A or 3B. Since side 3A and side 3B have basically the same configuration, only side 3A will be described in the following explanation, and the explanation for side 3B will be omitted. As shown in Figure 2, in this embodiment, the exhaust device 10A is located along the side 3A of the hull. In this embodiment, the exhaust device 10A is located between adjacent steel members 6 in the bow-stern direction FA. Figure 3 is a cross-sectional view of the exhaust system according to the present disclosure, as seen from the bow-stern direction.

The exhaust duct 11 defines a discharge path R through which the air exhausted by the exhaust fan 20 is discharged to the outside of the hull 2. The exhaust duct 11 comprises a lower duct 12 and an upper duct 13. The lower duct 12 is located below the upper deck 9A, which is positioned above the adjacent deck 9 in the vertical direction Dv. The lower duct 12 is located at the corner between the upper deck 9A and the side 3A. The lower duct 12 comprises a side plate 121, a bottom plate 122, an inclined plate 123, and a pair of end plates 124. The side plates 121 are positioned at a distance inward in the width direction W relative to the side 3A. The side plates 121 are parallel to the side 3A and extend downward from the upper deck 9A. The bottom plate 122 is positioned at a distance below the vertical direction Dv relative to the upper deck 9A. The bottom plate 122 is positioned below the lower end of the side plate 121 in the vertical direction Dv. The bottom plate 122 is parallel to the upper deck 9A and extends inward in the width direction W from the side 3A. The inclined plate 123 connects the lower end of the side plate 121 to the inner end of the bottom plate 122 in the width direction W. The inclined plate 123 is inclined in both the vertical direction Dv and
