  • the present invention relates to a ship which supplementally uses wind power as a propulsive force of the ship, and more particularly, to a ship which ensures a larger airspace in each ship side area and an accommodation area tower by building a tower for an accommodation area and is provided with a sail for using the wind power and a sail-deploying unit for the purpose of mainly using leading wind from a stern direction. That is, the invention relates to a ship which saves fuel cost and prevents air pollution, which is suitable for a merchant ship, and particularly which is advantageous for a beamy ship.
  • Non-Patent Literature 2 a hybrid sailing ship employing the “Sail main, Engine assist” system illustrated in Non-Patent Literature 2 has been also developed in order to further reduce the fossil fuel usage amount. Due to the “Sail main, Engine assist” system, the area of each sail increases and the burden of handling the sails also increases. To cope with them, it can be understood, as disclosed in Patent Literature 1, that the burden of handling each sail can be decreased by providing rigid wings as the sails and masts having elasticity. However, as evaluated as a merchant ship, the previous problem described herein above is quite true as well.
  • Non-Patent Literature 2 For the hybrid sailing ship employing “Sail main, Engine assist” system, for example, three or more huge retractable sails each having a width of 20 m and a height of 50 m in a sailing mode are provided at the front side when viewed from the stern (see FIG. 7 in a full sail mode of Non-Patent Literature 2). Since the field of vision toward the front side from the stern is disturbed, an additional problem arises in that this specification does not match Japanese Industrial Standard JIS F 0420: 2009 (ISO 8468: 2007) “Ships and marine technology-Ship's bridge layout and associated equipment-Requirements and guidelines” illustrated in Non-Patent Literature 3.
  • the total arc of blind sectors shall not exceed 20° within the required total field of vision of 225° [of 112.5° each from the bow toward either side].
  • No blind sector at either side shall exceed 10°.
  • No blind sector at either side shall exceed 5° within 10° from the actual bow toward either side.
  • the clear sector between two blind sectors shall not be less than the arc range of a larger blind sector among both the blind sectors”. Therefore, in the hybrid ship illustrated in FIG. 7 of Non-Patent Literature 2, the bridge and a part of the accommodation area are provided at a bow section and the rest of the accommodation area is provided at a stern section.
  • a bridge is placed at a stern section. Since a diesel engine, which is a propulsion mechanism, is located in a stern section, there cannot be a cargo space, namely, cargo cannot be loaded in the stern section. Thus, a bridge is provided in the stern section above the diesel engine in order to prevent the occurrence of a dead space on the deck. When a bridge is installed at a bow section, a new dead space can be formed therebelow. Even if the space can be utilized, the application in a merchant ship is limited and the burden of cargo handling becomes heavy.
  • Non-Patent literature 4 discloses a lifeboat lowering device, which is normally placed only at a stern section, which is additionally required to be installed also at a bow section. Accordingly, a design needs to be further changed and a design on the deck is limited (Non-Patent literature 4).
  • the invention mainly relates to a new hybrid ship attained by studying a method of using a wind-powered propulsive force while disposing the bridge at the stern, so that, without need of re-design on the entire structure of the hull and without further increase of burden on the cargo handling work as is conventionally done, this new hybrid ship does not further decrease the cargo space by the sailing facility, decreases the fuel consumption amount by using the wind-powered propulsive force, prepares a measure for an increase in fluid fuel price of an internal combustion engine for crude oil, and prevents air pollution in response to a reduction of CO 2 , using supplementally the wind-powered propulsive force.
  • a hybrid ship supplementally uses a wind-powered propulsive force in addition to a main engine and a propulsion device driven by the main engine.
  • a tower includes an accommodation area provided at a stern section and a bridge served as a navigating and maneuvering workstation and provided above the accommodation area.
  • a sail which is retractable to be stored in a side wall of the accommodation area and which is laterally deployable, is disposed in an airspace, which is located lateral to the accommodation area in the tower, below a height position of a floor surface of the bridge and above an upper deck.
  • An object of the invention is to create the larger airspace at each ship side by building the tower for the accommodation area including the bridge, and by installing the sail for using wind power and a sail-deploying unit for using leading wind mainly from a stern direction.
  • the tower is constructed such that the accommodation area extends upward from the upper deck, and a top portion of the tower above the accommodation area is provided with the navigating and maneuvering workstation (hereinafter, also referred to as the bridge). Since the tower is built for the accommodation area, a space, which would have been occupied by a conventional accommodation area and a bridge, becomes the airspace located lateral to the tower for the accommodation area, and the sail, which is retracted to be stored in the tower for the accommodation area, is disposed in this airspace above an upper deck below the height position of the floor of the navigating and maneuvering workstation so that the sail can be laterally deployed from the tower.
  • the navigating and maneuvering workstation hereinafter, also referred to as the bridge.
  • the tower is installed on the deck above a propulsion mechanism inside the ship at the stern section as in an arrangement of a bridge of a conventional ship, a dead space on the deck is excluded as a merchant ship, and a degree of freedom of installation of a cargo handling facility and a cargo space inside the ship is ensured.
  • the hybrid ship further can comprise a bridge wing, which is connected to the bridge served as the navigating and maneuvering workstation disposed above the accommodation area of the tower and which is extended to each of both ship sides.
  • the sail can be hung down from a yard to be laterally sail deployable to each of both ship side directions in a lower portion of an overhanging portion of the bridge wing, or below the overhanging portion of the bridge wing.
  • the navigating and maneuvering workstation provided at the top portion of the tower does not directly reach each ship side. It is preferable, for clear view from each ship side, to provide a wing bridge, which is connected to the navigating and maneuvering workstation of the tower and extended to the ship side.
  • the sail is hung down to be deployable below the overhanging portion of the wing extended toward the ship side. As one embodiment, the sail is hung down from the yard which enables to perform lateral sail deploying to each ship side direction below the wing, which ensures clear view from each ship side.

If the sail is made of the flexible material, the sail can be easily retracted to be stored inside the tower. For example, by deploying the sail in a curtain moving manner and by functioning retracting motion, there is an effect of reducing a total cost for building the ship including also the sailing mechanism. Further, since an upper deck space, which would be uselessly occupied by an extra sail retracting facility or sail folding facility, can be avoided, the degree of freedom of installation of the cargo handling facility and the cargo space inside the ship is ensured.
