Description

Ship with a detachable cover

Technical Field

The present invention relates to a ship for transporting cargo such as containers.

Background

In a ship for transporting cargo such as containers, the cargo is loaded in a cabin below a deck and on the deck. In a container ship for transporting containers, since the cargo is contained in the container, the cargo in the container is not wetted by rain even if it rains during transportation or loading and unloading operations at a dock. In contrast, in a cargo ship for transporting cargo requiring waterproof wetting, as described in patent document 1, a transport ship is provided with a top wall provided above a deck, a lower hold provided below the deck, and an upper hold provided above the deck.

As the number of loaded containers of a container ship increases, patent document 2 describes a container ship in which a container holding frame body located above the waterline is provided on the outer plate of the hull, and patent document 3 describes a container ship in which a projecting member projecting outside the hull is provided so as to be freely accommodated on the deck.

On the other hand, in a ship such as a container or a cargo ship, an internal combustion engine is generally used as a power source for propelling the ship, and a generator is mounted on a ship body in order to supply power to an electric appliance used in the ship. Patent document 4 describes a ship that supplies electric power to electric appliances inside the ship by solar power generation. Further, patent document 5 describes a solar boat (ソ - ラ - ボ - ト) having a folding solar cell to use the solar cell as driving energy for boat propulsion.

Patent document 6 describes a wing sail for utilizing wind power as a power source for propelling a vessel, the wing sail having a mast with an adjustable length. The sheet material as the sail portion is raised or contracted by the extension and contraction of the mast.

Disclosure of Invention

According to the description of patent document 1, in a transport ship having a lower hold provided on a lower side of a deck and an upper hold provided on an upper side of the deck, cargo in the lower hold is transported to the upper hold, and thereby loading and unloading work is performed from the upper hold side. That is, both the loading work of cargo into the lower hold and the unloading work of cargo from the lower hold to the outside of the ship need to be performed through the hatch provided in the deck. In the case of a small cargo ship, the cargo handling operation can be performed in a relatively short time even when the cargo is moved between the upper and lower tanks through the hatch when the cargo handling operation is performed, and in the case of a large container ship and a cargo ship, although the lower and upper tanks are designed in the hull, if the cargo handling operation is performed in the lower tank using the hatch provided on the deck, the cargo handling operation takes time and the operation efficiency is low.

Further, a conventional cargo ship and container ship have a hull formed integrally, and when a loading/unloading operation is performed, it is necessary to provide a single loading/unloading operation site at a dock, and a large number of flatbeds for loading/unloading operation and the like are moved to and from the dock, and thus, the workability cannot be improved.

On the other hand, in a ship having a solar panel partially provided on a deck, only electric power for supplying electric appliances in the ship can be generated, and an electric motor cannot be used as propulsion force of the ship. Further, as described in patent documents 2 and 3, in a ship having a container on a deck, a space for installing a solar cell cannot be secured.

Further, if the wing sail described in patent document 6 is installed on a container ship or a cargo ship, even if the mast is retracted to retract the sail cloth made of a sheet material, the wing sail interferes with the cargo ship or the cargo ship when the cargo ship or the cargo ship is unloaded.

The invention aims to provide a ship which can efficiently carry out loading and unloading operation of cargoes such as containers.

Another object of the present invention is to provide a ship in which a solar cell for supplying power to an electric motor for generating ship propulsion does not interfere with loading and unloading operations, and which can efficiently perform the loading and unloading operations.

Another object of the present invention is to provide a ship having wing sails for increasing the propulsive force of the ship by wind force, which does not interfere with the loading and unloading work and thus can efficiently perform the loading and unloading work.

Another object of the present invention is to provide a ship which can perform loading and unloading work efficiently by simultaneously performing loading and unloading work on a pair of ships at a plurality of locations separated from each other.

The ship of the present invention is a ship for transporting cargo such as containers, and is characterized by comprising: left and right projections provided on a deck provided on the hull to form a lower side hold in the hull and projecting with respect to the hull; a plurality of gate frames each including a vertical support fixed to an end of each of the left and right protruding portions and a horizontal beam connecting the vertical supports on both sides, the plurality of gate frames being provided at intervals in a longitudinal direction of the hull; a partition wall openably and closably attached between the frames to form an upper hold above the deck; a guide rail provided at a lower side of the deck and located in the lower-side hold to guide an in-ship crane for performing loading and unloading of cargo into and from the lower-side hold to an outboard work, the cargo being loaded into and unloaded from the upper-side hold into and out of the upper-side hold by a quay crane provided at a quay in a state where the partition wall is opened, and the cargo being loaded into and unloaded from the lower-side hold by the in-ship crane.

The ship of the present invention is characterized in that the partition wall is provided with a solar cell for converting solar energy into electric energy, and in a state where the partition wall is closed, the solar cell supplies electric power to an electric motor for driving a propeller that applies thrust in a sailing direction to the hull. The vessel of the invention is characterized in that the vessel further comprises a wing sail comprising: a support column attached to the frame body and capable of freely swinging between a standing position and a storage position; a plurality of support beams provided on the pillars and extending in a width direction; a sheet mounted on the support beam.

The ship of the present invention is characterized in that the propeller is provided on the stern side of the hull and applies thrust in the traveling direction to the hull by electric power of a battery provided in the hull, and the propeller is provided on the bow side of the hull and applies thrust in the width direction and thrust in the traveling direction to the hull by electric power of the battery (スラスタ).

The ship of the invention is characterized in that the hull comprises a bow-side module, a stern-side module, and at least one intermediate module arranged between and connected to the bow-side module and the stern-side module, so that the length of the hull can be varied. The ship of the present invention is characterized in that at least one of the left and right protrusions is provided with a lifter for transporting passengers between the inside and outside of the ship.

According to the present invention, since the ship has the lower tank below the deck and the upper tank above the deck, the loading and unloading work for the lower tank is performed by the in-ship crane provided in the lower tank, and the loading and unloading work for the upper tank is performed by the quay crane, the loading and unloading work for the ship can be efficiently performed.

The upper ship cabin is covered by a partition wall which can be freely opened and closed, and the solar cell is arranged on the partition wall, so that the electric energy generated by the solar cell can be utilized to apply the propelling force to the ship through a propeller driven by an electric motor. The upper tank can be efficiently loaded and unloaded by opening the partition wall.

Since the wing sail to which the propulsive force is applied can swing freely between the standing position and the storage position, the wing sail in the storage position does not interfere with the loading and unloading work when the ship is parked at a dock and the loading and unloading work is performed, and therefore the loading and unloading work can be efficiently performed. When the ship is sailing, the wing sails are in the standing position, so that the wind power can be used as the propulsion force of the ship.

By using solar energy and wind energy as the propulsive force of the ship, the ship is propelled without using petroleum fuel as in the case of an internal combustion engine or the like. Thus, no exhaust gas generated by the internal combustion engine is discharged to the atmosphere, and clean navigation is possible.

The ship body is composed of a bow side module, a stern side module and at least one middle module arranged between the bow side module and the stern side module, so that the whole length or the cargo capacity of the ship can be changed according to the transported cargo amount, and the cargo can be efficiently transported.

Detailed Description

The following describes in detail a specific embodiment of the present invention with reference to the drawings. In particular, the vessel 10 of the present invention shown in fig. 1 is a container ship for shipping containers on water.

As shown in fig. 4, the ship 10 includes a hull 14, the hull 14 including a bottom wall 11 and left and right side walls 12, 13 formed integrally with the bottom wall 11, upper end portions of the side walls 12, 13 being respectively provided as portions bent outward in a width direction of the hull 14. The upper ends of the left and right side walls 12, 13 are provided with a deck, i.e., a deck 15, and a lower tank 16 surrounded by the bottom wall 11, the left and right side walls 12, 13, and the deck 15 is formed in the hull 14.

The deck 15 has projections projecting from the left and right sides of the hull 14. In fig. 4, the width of the hull 14 is D0, the width of the deck 15 is D1, D1 is set larger than D0, and reference numerals 17, 18 denote left and right projecting portions. As shown in fig. 1 to 3, the deck 15 is provided with a plurality of gate frames 21 spaced apart from each other in the longitudinal direction of the hull 14. As shown in fig. 4, each frame body 21 includes vertical supports 22 and 23 fixed to the end portions of the protruding portions 17 and 18, respectively, and a horizontal beam 24 connecting the vertical supports on both sides. The hull is provided with eighteen frames 21 in total, and in fig. 2, the frames 21 from the bow side to the stern side are denoted by reference numerals (a) to (r). Although the number of the frame bodies 21 provided on the hull 14 is eighteen in the illustrated ship 10, any number may be provided depending on the length of the hull 14.

A partition wall 25 that can be opened and closed is provided between two paired housings adjacent in the longitudinal direction of the hull 14, and an upper hold 26 is formed by the housings 21 and the partition wall 25 on the upper side of the deck 15. In the illustrated ship 10, the partition walls 25 are provided at twelve locations that are paired between the housings 21, and in fig. 3, the partition walls 25 on the bow side to the partition walls 25 on the stern side are denoted by reference numerals (a) to (1). Each of the partitions 25 is formed of a sheet-shaped flexible member provided with a solar cell for converting solar energy into electric energy, and each of the partitions 25 is slidably attached along a guide groove formed in the frame 21. As shown in fig. 3, each partition wall 25 is divided into two in the width direction of the hull 14, and if the two left and right partition walls 25 are located at positions where they are in contact, the partition walls 25 are in a closed state.

As shown in fig. 4, the upper end of one vertical support column 22 is provided with a reel 27, and the lower end of the other vertical support column 23 is provided with a reel 28. Therefore, the partition wall 25 divided into the left and right pieces is wound by the reels 27, 28, respectively, so that the partition wall 25 is in an opened state. On the other hand, the partition wall 25 is in the closed state shown in fig. 1 to 3 by rewinding the reels 27, 28. Once the closed state is entered, electricity is generated by the solar cell provided on the partition wall 25, and the generated electricity is stored in a not-shown battery provided inside the hull 14.

As shown in fig. 4, a reel 27 for winding the partition wall 25 on the port side is provided at the upper end portion of the vertical column 22, and an opening/closing window 29 is provided below the reel. The opening/closing window 29 is openably and closably attached to a bracket, not shown, and when the opening/closing window 29 is opened, the inside of the upper tank 26 can be ventilated to adjust the temperature and humidity inside the upper tank 26. Similarly to the partition wall 25, the opening/closing window 29 is provided with a solar cell, and the opening angle of the opening/closing window 29 can be adjusted to the sunlight, so that the power generation efficiency of the solar cell provided in the opening/closing window 29 can be improved when the opening/closing window is opened.

By providing all the reels 27 on the port side at the upper end portion of the vertical column 22, the opening/closing window 29 provided with the solar cell can be provided below all the reels 27. In addition, the opening and closing windows 29 may be provided at regular intervals in the longitudinal direction of the hull 14, and in this case, the reel 27 for winding the partition wall 25 corresponding to the portion where the opening and closing windows 29 are not provided is provided at the lower end portion of the vertical pillar 22.

As shown in fig. 4, the opening/closing window 29 is provided on the port side, and may be provided on the starboard side, in which case the reel 28 is provided at the upper end portion of the vertical column 23. In this way, when the opening/closing windows 29 with solar cells are provided on both the starboard side and the port side, the power generation efficiency can be improved.

As shown in fig. 4, a lower tank 16 located below the deck 15 is provided in the hull 14, an upper tank 26 is provided above the deck 15, and the lower tank 16 contains a container 30a and the upper tank 26 contains a container 30 b. When the ship 10 is underway, the upper tank 26 is shielded from the outside of the ship by the partition wall 25, and therefore the containers 30b in the upper tank 26 are not caught by or splashed with water droplets such as rainwater or seawater. And, solar energy can be converted into electric energy by shielding the partition wall 25 of the container 30b in the upper hold 26 while navigating, thereby charging the battery.

As shown in fig. 2, a plurality of doors, that is, opening and closing doors 31 are provided on the upper portion of the starboard side wall 13 of the hull 14, and in a state where the opening and closing doors 31 are opened, an operation of loading the container 30a into the lower tank 16 and an operation of unloading the container from the inside of the lower tank 16 to the outside of the ship are performed. Rails 32 are attached to the lower side of the deck 15 so as to correspond to the opening/closing doors 31, and each rail 32 extends to the projection 18 on the starboard side. As shown in fig. 4, an inboard crane 33 is attached to each guide rail 32, and the inboard crane 33 is used for an operation of loading the container 30a into the lower tank 16 and an operation of unloading the container from the lower tank 16 to the outside, that is, a loading and unloading operation.

Fig. 4 shows a state where the unloading work is performed at the quay 34, and the containers 30a in the lower-side hold 16 are unloaded to the outside of the ship by the in-ship crane 33 and loaded on the flat car 35a of the quay 34. The quay 34 is provided with a quay crane 37 for unloading the containers 30b in the upper hold 26. The container 30b in the upper ship tank 26 is loaded on the flat car 35b by the quay crane 37. Although fig. 4 shows an operation state of unloading the containers 30a and 30b from the ship 10, when the containers 30a and 30b are loaded from the quay 34 into the ship 10, the loading operation into the lower ship tank 16 is performed by the ship crane 33, and the loading operation into the upper ship tank 26 is performed by the quay crane 37. In this way, the lower tank 16 and the upper tank 26 can be loaded simultaneously in the ship 10 having the upper tank 26 and the lower tank 16 arranged in two stages, and the loading operation can be efficiently performed.

Further, as shown in fig. 2, since a plurality of opening/closing doors 31 are provided, the loading/unloading work of the lower tank 16 can be simultaneously performed at a plurality of positions by opening all the opening/closing doors 31. Further, the loading and unloading work to the upper tank 26 can be simultaneously performed at a plurality of positions by opening all the partition walls 25. When the loading and unloading work is performed on the upper tank 26, the partition wall 25 is opened and partially removed from the horizontal beam 24 of the frame 21, so that the loading work is not hindered by the partition wall 25 used as the solar cell, and the loading work can be efficiently performed.

In the illustrated ship 10, as shown in fig. 4, the opening/closing door 31 is provided on the side wall 13 on the starboard side, but the opening/closing door 31 may be provided on the side wall 12 on the port side, or may be provided on the side walls 12 and 13 on both sides. When the opening/closing door 31 is provided on the side walls 12, 13 on both sides, the guide rail 32 is extended to the left and right protruding portions 17, 18. Although the guide rail 32 is formed in a state of protruding to the protruding portion 18, in a case where the end portion of the guide rail 32 is slidable with respect to the base end portion in the lower tank 16, the end portion of the guide rail 32 may protrude to the protruding portion 18 at the time of the cargo handling operation.

As shown in fig. 2, the hull 14 includes a bow-side module 14a, a stern-side module 14b, and intermediate modules 14c, 14d provided therebetween, and one hull 14 is formed by connecting these modules. As for the configuration of the hull 14, the overall length of the hull 14 can be changed by modifying to a configuration composed of only the bow-side module 14a and the stern-side module 14b and a configuration having an arbitrary number of intermediate modules. In this way, the entire length of the hull 14 can be changed according to the load amount of the ship 10 loaded once, thereby changing the load amount, and the loading work can be performed by each quay crane 37.

Fig. 5 (a) is a rear view showing a rear end surface of the bow-side module 14a, and fig. 5 (B) is a side view showing a connection structure of the bow-side module and the intermediate module.

As shown in fig. 5 (a), an end wall 40 is provided on the rear end of the bow-side module 14a to close the lower tank 16 inside, thereby enabling the bow-side module 14a to freely sail alone. The intermediate modules 14c, 14d are provided at both ends thereof with respective end walls, not shown, and enclose the lower side tanks 16 inside so as to be respectively in a state of being able to float on the water surface. An end wall, not shown, is also provided on the front end face of the stern-side module 14b to close the inner lower hold 16, enabling the stern-side module 14b to sail freely alone.

As shown in fig. 5, a plurality of first engagement members 41 are movably and adjustably attached to an end wall 40 of the bow-side block 14a in the vertical direction, and a plurality of second engagement members 42 corresponding to the first engagement members 41 are movably and adjustably attached to a front end wall of the intermediate block 14 c. Therefore, in order to connect the bow-side block 14a and the middle block 14c, the vertical heights of the respective joining members 41, 42 are adjusted, and the blocks 14a, 14c on both sides are connected to each other by the joining members 41, 42 in a state where the blocks 14a, 14c on both sides are brought into contact.

Similarly, a first engaging member 41 is mounted on the rear side end wall of the intermediate block 14c, and a second engaging member 42 is mounted on the front side end wall of the intermediate block 14 d. A first engaging member 41 is attached to a rear end wall of the intermediate module 14d, and a second engaging member 42 is attached to a front end wall of the stern side 14 b. Thus, the hull 14 composed of four modules is formed by the respective joint members 41, 42 being connected to each other.

The structure of the hull 14 includes a type in which the hull structure is formed of a single module, such as a normal ship, in addition to the type in which the plurality of modules are connected to form one hull 14, but the loading work can be performed in a plurality of areas by the module connection structure, and the loading work can be performed more efficiently.

Fig. 6(a) to (C) are loading operation process diagrams showing an example of loading operation of the ship 10 having the module connecting structure shown in fig. 1 to 3. In a state close to the quay, the hull 14 shown in fig. 6(a) is separated by portions of the intermediate modules 14c, 14 d. In this way, the hull 14 is separated into two parts, a part connecting the bow-side module 14a and the middle module 14c, and a part connecting the stern-side module 14b and the middle module 14 d. In this state, the portion connecting the bow-side module 14a and the middle module 14c shown in fig. 6 (B) is made to sail to the loading dock 34c, and the portion connecting the stern-side module 14B and the middle module 14d is made to sail to the loading dock 34 d.

Next, as shown in fig. 6 (C), the bow-side module 14a is separated from the middle module 14C, and the bow-side module 14a is parked at the loading/unloading site 34a of the quay 34 in a state where the middle module 14C is left in the loading/unloading dock 34C. Similarly, the stern-side module 14b is separated from the middle module 14d, and the stern-side module 14b is docked at the loading/unloading work site 34b of the quay in a state where the middle module 14d is left in the loading/unloading dock 34 d. Quay cranes 37a and 37b are provided at each loading/unloading work site, and quay cranes 37c and 37d are provided at loading/unloading docks 34c and 34 d.

Fig. 7 is an enlarged view showing the bow-side module 14a and the middle module 14C shown in fig. 6 (C), and shows a state in which the respective modules are subjected to the loading and unloading work.

Therefore, the containers 30b in the upper tank 26 divided into four parts can be loaded and unloaded simultaneously by the quay cranes 37a to 37 d. At the same time, the containers 30a in the lower tank 16 divided into four parts can be loaded and unloaded by the respective in-ship cranes 33. By dividing the hull 14 into 4 sections in this way, the loading and unloading work of the upper ship tank 26 of one ship 10 can be efficiently performed using the plurality of quay cranes 37a to 37 d.

In the frame 21 provided in the bow-side module 14a, the housing space 45a is provided between the frames 21 having the marks (c) and (d), and in the frame 21 provided in the stern-side module 14b, the housing space 45b is provided between the frames 21 having the marks (o) and (p). Further, an accommodation space 45c is provided between the frame 21(f) provided at the rear end portion of the bow-side module 14a and the frame 21(g) provided at the front end portion of the intermediate module 14c, and an accommodation space 45d is provided between the frame 21(m) provided at the front end portion of the stern-side module 14b and the frame 21(1) provided at the rear end portion of the intermediate module 14 d. Wing sails 46 are mounted on the right and left sides of the hull 14 on the day of the storage spaces 45a to 45d of the frame 21.

Fig. 8 is a perspective view showing the wing sail 46 provided on the frame body 21 and located in the housing space 45 a. The wing sail 46 has a support column 47, the support column 47 is formed of a plurality of support column segments 47a to 47g, the outer diameters of the support column segments 47a to 47g are gradually reduced from the base end portion side to the tip end portion side, the support column segments forming the support column 47 have a hollow structure and are formed in a nested (in れ) type that can be slidably inserted into the support column segments on the base end portion side, and the support column 47 is entirely extendable and retractable. Support beams 48a to 48g extending in the width direction of the wing sail are provided to the respective strut sections 47a to 47g, and a sheet 49 is attached to the support beams 48a to 48 g.

Fig. 9 is a perspective view showing the column section 47b of the wing sail 46 and the horizontal support beam 48b provided on the column section 47 b. The width of the column-side portion of the horizontal support beam 48b is large, and the width of the end-extending portion is gradually reduced. Fig. 8 and 9 show the wing sail disposed in the storage space 45a, and the other wing sails disposed in the other storage spaces 45b to 45d have the same configuration. Since each strut 47 of the wing sail 46 is telescopic, the overall length thereof can be shortened when the strut segment on the tip end side is inserted while being slid on the strut segment on the base end side. The column section 47a on the base end portion side is mounted so as to be rotatable with respect to the frame body 21 as indicated by an arrow a in fig. 8, while being swingable between a standing position and a housed position into the housing space as indicated by an arrow B.

Therefore, during the loading and unloading work, the wing sails 46 are accommodated in the accommodating spaces 45a to 45d, and the wing sails 46 are prevented from interfering with the loading and unloading work. On the other hand, when the ship 10 is underway, the propulsive force of the ship 10 can be increased by using the wind energy blowing to the wing sails 46. Although the illustrated ship 10 has 8 wing sails 46 in total, the number thereof may be set arbitrarily.

In addition to the plurality of wing sails 46, a sheet-like triangular sail 50 is mounted to the frame 21 and to one of the wing sails 46. The triangular sail 50 is fixed at two corners to the frame 21 and at the other corner to the tip of one wing sail 46, and the wind force increases the propulsive force of the ship 10 by the triangular sail 50. When the vessel 10 is not underway, the triangular sail is folded and stowed.

Fig. 10 (a) is a bottom view of the stern-side module 14B, and fig. 10 (B) is a bottom view of the bow-side module 14 a.

As shown in fig. 10 (a), the bottom wall 11 of the stern-side module 14b is provided with two propulsion pipes 51 extending in the longitudinal direction, and the inside of the end openings of the two propulsion pipes 51 is fitted into the main propeller 52 as indicated by a broken line. Behind the propulsion pipe 51, a sub-propeller 53 is mounted on the rudder 54, and the sub-propeller 53 can apply a thrust in the sailing direction to the hull 14. Further, when the auxiliary propeller 53 is driven by rotating the rudder unit 54, a thrust in the width direction can be applied to the hull 14. The sub-thruster 53 has a function of stern propulsive force.

The main and sub-propellers 52, 53 are driven by electric motors, not shown, provided in the hull 14, and the electric motors are directly powered by the power of the solar cells provided on the partition wall 25 or are powered by batteries provided in the hull 14. Since the stern-side module 14b is provided with the thrusters 52 and 53, the stern-side module 14b and the intermediate module 14d sail by the thrust of the thrusters 52 and 53 as shown in fig. 6 (a). The stern side module 14b can sail alone by means of the thrusters 52, 53.

As shown in fig. 2, the bottom wall 11 of the bow-side module 14a is inclined upward toward the bow, and the bow-side region of the bottom wall 11 is provided with a central bulging portion 55. The multifunctional bow pusher 56 is provided on both left and right sides of the rising portion 55.

Fig. 11 is an enlarged side view showing the multi-function bow pusher 56 provided on the starboard side of the bulging portion 55, the multi-function bow pusher 56 having a movable holding portion 58 attached to a spherical joint portion 57, and a bow-side propeller 59 provided at an end of the movable holding portion 58. Like the two main and auxiliary propellers 52, 53 on the stern side, the propeller 59 on the bow side is driven by an electric motor.

As shown in fig. 11 (a), when the propeller 59 of the multi-function bow propeller 56 is in a state of entering into the recess 60 provided in the ridge portion 55, the propeller 59 faces the width direction of the hull 14. In this state, the propeller 59 is driven, and when the hull 14 approaches a quay or the like, a thrust in the width direction can be applied to the hull 14.

On the other hand, as shown in fig. 11 (B), when the propeller 59 of the multi-functional bow pusher 56 is in a state of facing the sailing direction in water, the propeller 59 is driven in this state, and thrust in the sailing direction is applied to the hull 14 by the propeller 59. Further, as shown in fig. 11 (C), when a part of the propeller 59 is in a state of protruding from the water surface WL and the propeller 59 is in a state of facing the sailing direction, a large number of bubbles, i.e., generated bubbles, are generated by the propeller 59 and transferred to the concave portion provided on the central rising portion 55 so that the bubbles are blown to the bottom wall of the ship, by which the frictional resistance of the hull is reduced and the ship 10 can be sailed with less propulsive force.

Since the bow-side module 14a is provided with the multi-function bow pusher 56 having the pusher 59, when the bow-side module 14a and the middle module 14c are sailed, as shown in fig. 6(a), sailing is performed by the propulsive force obtained by the pusher 59 of the multi-function bow pusher 56. The bow-side module 14a can be sailed by the propeller 59 alone.

The propellers 52, 53, 59 applied to the propulsive force of the vessel 10 are all driven by electric motors, and the electric power to the electric motors may be supplied directly by solar cells that convert solar energy into electric energy by solar cells provided at the partition wall 25, or supplied by batteries. Further, in order to convert the wind into the propulsive force of the vessel 10, the vessel 10 is provided with wing sails 46 and a triangular sail 50. In this way, the ship 10 can sail by means of solar energy and wind power without using an internal combustion engine, thereby being able to sail economically without consuming petroleum fuel. Further, when the ship 10 is sailing at a higher speed, the electric power can be increased by a fuel cell, not shown, installed in the lower deck, and the electric power can be adjusted.

Although the area required for supplying electric power to the electric motors for driving the respective propellers is large, since the solar cell is provided on the partition wall 25 formed so as to cover the upper-side hold 26 of the ship 10, sufficient electric power can be secured for propulsion of the ship by the upper surface area of the ship 10. The partition wall 25 as a solar cell is of an open-close type, and in the open state, the partition wall 25 does not interfere with the attaching and detaching operation, and the attaching and detaching operation can be performed easily.

Fig. 12 is an enlarged perspective view showing a part of the bow-side module 14a of the ship 10. The deck upper side of the bow-side module of the ship 10 is provided with a bridge and a residential area, and as shown in fig. 12, the starboard-side projecting portion 18 is provided with a lift 61 for transporting crew between the inside and outside of the ship. The lifter 61 includes a telescopic lifter post 62 and an occupant seat carrier 63 provided at a lower end portion of the lifter post 62. The lifter strut 62 includes a strut section formed in a small size along the direction from the upper end side to the lower end side, and is formed in a nested type in which the lower strut section is inserted inside the upper strut section. By using the lift 61, the passenger can move between the dock and the ship 10, and also between the ship 10 and a small ship.

By using the protrusion 18 and providing the lifter 61 at the protrusion 18, it is possible to safely move the occupant between the inside and outside of the ship, compared to using a ladder. The lifter 61 may be provided on the port-side protrusion 17, or may be provided on the left and right protrusions 17, 18.

As shown in fig. 12, the elevator 61 may be configured not only in a telescopic type as a nested type, but also in a type in which the carrier 63 is moved up and down by a cable or the like.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the illustrated ship 10 is a container ship for transporting containers, but the transported goods are not limited to only containers, and the present invention can be applied to a cargo ship for transporting various goods.

The ship is suitable for container ships and cargo ships, and can utilize solar energy and wind power as the propelling force of the ship.
