Description

Cargo ship

Technical Field

The utility model relates to a cargo ship.

Background

In a cargo ship in which a power region, a cargo region, and a bow region are arranged in this order from the stern to the bow, the following may occur: a deck house including a living area and a bridge is provided on the bow side of the cargo area (patent document 1).

The following reasons are listed: when the height of the cargo is higher than the exposed deck, if the deck room is provided closer to the stern side than the cargo area, the visibility of the ship bridge in the deck room in the bow direction is impaired by the cargo.

In addition, the purpose of the quietness of the living area may be. This is because if the deck room is provided closer to the bow than the cargo area, the distance between the power area and the residential area becomes longer than if the deck room is provided closer to the stern than the cargo area, and the noise of the main unit becomes less likely to be transmitted to the residential area. In addition, safety of a residential area may be aimed. This is because if the distance between the power plant and the residential area becomes longer, the residential area is less likely to be damaged in the event of an explosion or gas leakage accident in the power plant. Further, since a safety device such as an explosion-proof structure for a residential area of an accident can be simplified, construction cost can be reduced.

Patent document 1: japanese patent laid-open publication No. 61-132488.

In order to reduce construction costs without reducing the volume of a cargo room in a cargo ship, it is necessary to shorten the total length of a hull without shortening the width of a cargo area, the depth of the cargo area, and the length in the ship length direction.

However, when the deck house is provided on the bow side of the cargo area, if the ship length becomes shorter, the deck house must be provided on a narrow-end exposed deck on the bow side, and the width of the living area becomes narrower.

In the case where it is desired to secure the floor area of the residential area even if the width of the residential area is narrow, it is possible to increase the number of floors of the deckhouse. It is also conceivable to extend the deckhouse in the bow direction to secure a floor area of a residential area, but the distance between the mooring machine and the deckhouse on the exposed deck existing on the bow side is too short, and it is difficult to secure a mooring work area for operating the mooring machine.

SUMMERY OF THE UTILITY MODEL

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a general structure of a cargo ship 1 according to the present embodiment will be described with reference to fig. 1 and 2.

Here, as the cargo ship 1, the following ship is exemplified: the liquefied gas transport ship transports liquefied gas loaded in a liquefied gas tank 17 as cargo, and a deck room 23 including a residential area and a bridge is disposed on the bow side of a cargo area 7 where the liquefied gas tank 17 is loaded.

As shown in fig. 1, the cargo ship 1 includes a hull 3, a deckhouse 23, and a mooring machine 29.

The hull 3 is a structure that becomes a hull of the cargo ship 1, and is configured to surround the inside of the ship with the bottom 71, the side walls 81, and the exposed deck 61. The specific shape of the ship, the hull structure, or the arrangement of watertight bulkheads, etc. are appropriately designed according to the use of the cargo ship 1.

As shown in fig. 1, a power region 5, a cargo region 7, and a bow region 9 are arranged in this order from the stern to the bow inside the hull 3.

The power region 5 is a region where a propulsion mechanism of the cargo ship 1 such as a main engine is arranged, and is a region closest to the stern side of the hull 3 in the ship length direction.

A power bulkhead 15 as a transverse bulkhead of watertight construction is provided at the most tip in the bow direction of the power section 5, and the power section 5 and the cargo section 7 are partitioned in the ship length direction by the power bulkhead 15.

On the bare deck 61 above the power section 5 are provided as required: a decorative chimney 13 in which an exhaust pipe for exhausting exhaust gas generated by combustion of the main body is disposed; the engine case 11 houses an exhaust gas treatment device and the like.

The cargo area 7 is an area where the cargo carried by the cargo ship 1 is arranged, and is provided between the power area 5 and the bow area 9 in the ship length direction.

A cargo bulkhead 21 as a transverse bulkhead of a watertight structure is provided at the most tip end in the bow direction of the cargo area 7, and the bow area 9 and the cargo area 7 are partitioned in the ship length direction by the cargo bulkhead 21.

The volume of the cargo area 7 is set in consideration of the displacement and resilience of the hull 3, the cargo weight, and the like, but a rectangular parallelepiped is preferable in order to increase the cargo capacity as much as possible. The width of the bare deck 61 from one side of the cargo area 7 to the other side is therefore constant.

Since a liquefied gas carrier is illustrated as a cargo ship 1 in fig. 1, a liquefied gas tank 17 is disposed in the cargo area 7.

The liquefied gas tank 17 is a tank that stores liquefied gas. The liquefied gas is a gas that is gaseous at normal temperature and pressure, and is cooled and compressed to become a liquid.

The following example is shown in fig. 1: two independent tanks each having a cylindrical shape with hemispherical ends are arranged in series, and the length direction of each tank faces the ship length direction. However, the shape, structure, capacity, and number of the liquefied gas tanks 17 can be set as appropriate in accordance with the displacement and recovery of the hull 3, the volume of the cargo area 7, the load weight of the liquefied gas, and the temperature and pressure of the liquefied gas at the time of loading.

The liquefied gas tank 17 installed in the cargo area 7 has a portion higher than the exposed deck 61 above the power area 5 in fig. 1. Therefore, the tank cover 19 is provided without the exposed deck 61 above the liquefied gas tank 17. The tank cover 19 is a cover that covers and protects the liquefied gas tank 17, and is provided at a position higher than the exposed deck 61.

The bow zone 9 is a zone where the side thruster 33 and an anchor device, not shown, are provided, and is a zone closest to the bow side of the hull 3 in the ship length direction.

The stern-side end of the bow region 9 is separated from the cargo region 7 by a cargo bulkhead 21.

In order to improve the undulation of the hull 3 and reduce the thrust resistance, the bow region 9 has a shape tapered from the stern side toward the bow side tip in a plan view (see fig. 2 (b)). Therefore, the exposed deck 61 on the bow region 9 also has a shape tapered from the stern side toward the bow side tip in a plan view.

The bow zone 9 shown in fig. 1 is divided into two zones in the direction of the length of the ship by means of a crash bulkhead 31 which is a transverse bulkhead of watertight construction.

Of the two regions, the region on the stern side in the ship length direction is a stern-side hollow region 9 a. The stern-side hollow area 9a is an area below the deckhouse 23, and is provided with a passage, a ballast tank, a fuel tank, and the like for a crew to enter the interior of the hull 3 from the deckhouse 23 as necessary.

Of the two regions, the region on the bow side in the ship length direction is a bow-side hollow region 9 b. A not-shown anchor device is provided in the bow-side hollow region 9 b.

A lateral thruster 33 is provided in the bow-side hollow space 9b as shown in fig. 1. The side thruster 33 is a propulsion mechanism for moving the hull 3 in the lateral direction, i.e., the ship width direction. The side thruster 33 shown in fig. 2 (a) is a rotary screw, is detachably disposed in a cylindrical duct 51 that penetrates both sides of the bow-side hollow region 9b in the ship width direction, and laterally moves the hull 3 to the left ship side or the right ship side by rotating the ship width direction about the central axis. The reason why the side thruster 33 is detachable is because it needs to be detached from the tunnel 51 at the time of maintenance.

The deckhouse 23 is a multi-story upper structure including a crew residence and a bridge serving as a command post for operations, and the crew residence is disposed on the lower story and the bridge serving as the command post is disposed on the upper story.

As shown in fig. 1, the deck house 23 is provided on the exposed deck 61 on the bow region 9, and is provided on the bow side of the cargo region 7. This is because, in the cargo ship 1, the height of the liquefied gas tank 17 and the tank cover 19 is higher than the exposed deck 61, and if the deck room 23 is provided on the stern side of the cargo space 7, the visibility from the bow direction of the bridge in the deck room 23 is blocked by the tank cover 19, and the visibility is deteriorated. In addition, it is also for the purpose of ensuring the quietness of the residential area and the safety of the residential area within the deckhouse 23, and the simplification of the security device.

The mooring machine 29 is a winch that pulls out and winds a rope fixed to a mooring facility such as a mooring column, a mooring buoy, and a mooring pile when the cargo ship 1 is parked at a port, and the mooring machine 29 is provided on an exposed deck 61 in front of the deckhouse 23. Here, the forward direction is the bow end side in the bow direction.

The mooring machine 29 may have a known structure as long as it has a structure capable of pulling out and winding a rope having a length and thickness necessary for mooring the cargo ship 1.

The mooring machine 29 shown in fig. 2 is provided with a mooring operation machine 53. The mooring operation machine 53 is a machine for the operator 2 to operate the mooring machine 29, and is, for example, a handle or a lever operated by the operator 2 when the operator pulls out or winds the rope.

The above is a description of the general structure of the cargo ship 1.

Next, the details of the structure in the vicinity of the deckhouse 23 will be described with reference to fig. 2 to 4.

As shown in fig. 2 and 3, a recessed portion 27 recessed toward the stern side is provided in a portion of the front surface 41 of the deckhouse 23, which is located behind a mooring work machine 53 provided in the mooring machine 29.

Since the recess 27 is located behind the mooring work machine 53, the operator 2 who performs the mooring work is located at a position where the operator can visually recognize at least the mooring work machine 53. The recess 27 is thus a mooring work area which is an area where the mooring operation machine 53 is operated.

Since the recess 27 is a mooring work area, a footing 27a is provided on the floor surface, at which the operator 2 who performs the mooring work stands when operating the mooring work machine 53.

In this way, in the cargo ship 1, the deck room 23 is extended to the bow side of the foothold 27a where the operator 2 operates the mooring operation machine 53, and the floor area of the living area is secured. Further, the operator 2 operates the mooring work machine 53 by providing the foothold 27a in the recessed portion 27 of the front surface 41 of the deckhouse 23 behind the mooring work machine 53, thereby also securing the mooring work area.

That is, even when the floor area of the residential area is secured by extending the deckhouse 23 toward the bow side to such an extent that the operator 2 cannot perform the mooring work between the front surface 41 of the deckhouse 23 excluding the recess 27 and the mooring work machine 53 and bringing the deckhouse 23 close to the mooring work machine 53, the mooring work area can be secured by the foothold 27a of the recess 27.

Therefore, even when the deck house 23 including the residential area and the bridge is provided on the exposed deck 61 having the tapered shape on the bow side, the floor area of the residential area and the mooring work area can be secured.

The configuration of the foothold 27a is set according to the height of the mooring operation machine 53. In the case where the mooring operating machine 53 is set at a height from which the operator 2 can operate the mooring operating machine 53 from the bare deck 61, the floor surface of the recess 27 is the bare deck 61, and the bare deck 61 is the foothold 27 a. In this case, it is advantageous that a structure for adjusting the height as in a work table is not required on the floor surface of the recess 27.

The foothold 27a is a work table provided on the bare deck 61 of the floor surface of the recess 27 in a case where the mooring operation machine 53 is provided at a position higher than a height at which the operator 2 can operate the mooring operation machine 53 from the bare deck 61.

In this configuration, the foothold 27a can be set to a height at which the worker 2 can easily perform work by adjusting the height of the work table, which is advantageous in workability. The foothold 27a may be formed by making the floor surface of the recess 27 higher than the bare deck 61. The same effect as in the case where the work table is provided can be obtained also in this configuration.

Since the recess 27 is a mooring work area, the mooring work machine 53 is preferably located in a work area R where the worker 2 can operate from the foothold 27a as shown in fig. 3.

Here, the working area R is a range in which the operator 2 located at the foothold 27a of the recessed portion 27 reaches the mooring work machine 53 by extending his or her hand.

The mooring operation machine 53 is located in the working area R where the operator 2 can operate from the foothold 27a, so that the operator 2 can directly operate the mooring operation machine 53 by hand from the foothold 27a surrounded by the recessed portion 27. So that no remote operation of the mooring 29 is required.

In the case of remotely operating the mooring operation machine 53, the mooring operation machine 53 may be disposed outside the range of the working area R where the operator 2 can operate from the foothold 27 a. However, in this case, since the foothold 27a is located rearward of the mooring operation machine 53, the operator 2 can operate the mooring operation machine 53 while visually recognizing it from the foothold 27a, and the workability is good.

The shape and size of the recess 27 are appropriately set to a range within which the operator 2 can enter and work during the mooring work. The shape of the recess 27 shown in fig. 2 and 3 is a depression as follows: only one surface facing the bow direction is opened, the other surface is a wall surface of the deckhouse 23, and the recess 27 is a cubic space, but may be a shape other than a cube, for example, a semi-cylindrical shape, as long as the mooring work is not affected.

The length L in the ship length direction of the concave portion 27 shown in fig. 2 (a) and the width W in the ship width direction of the concave portion 27 shown in fig. 2 (b) are dimensions at least as large as the operator 2 can enter. Since the larger the length L and the width W are, the wider the mooring work area becomes, the efficiency of the mooring work improves, but the floor area of the residential area decreases. Therefore, the length L and the width W are set in consideration of both the efficiency of the mooring work and the floor area of the residential area.

Specifically, the maximum value of the length L in the ship length direction of the recessed portion 27 is preferably shorter than the minimum value of the length L0 of the deckhouse 23. In this configuration the populated area is located behind the recess 27.

However, when it is desired to secure a sufficient mooring work area, the length L may be set to be the same as the length L0 of the deckhouse 23, and the recess 27 may be formed in a tunnel shape penetrating the deckhouse 23.

Further, it is preferable that the maximum value of the width W in the ship width direction of the recess 27 shown in fig. 2 (b) is shorter than the minimum value of the width W1 of the front surface 41 of the deckhouse 23.

In this structure, since a part of the deckhouse 23 is disposed on both side surfaces of the recess 27, the floor area of the residential area can be made wider. However, in the case where the recess 27 has the ceiling 27b and it is desired to sufficiently secure the mooring work area, the width W may be set to be the same as the width W1. Specifically, both side surfaces of the recess 27 may be opened to have the following shapes: the floor of the deckhouse 23 above the ceiling 27b protrudes from the floor below the ceiling 27 b.

The maximum height H from the floor surface of the recess 27 to the ceiling 27b must be at least higher than the height of the worker 2 and the mooring operating machine 53. This is because if the maximum height H is smaller than the height of the worker 2 and the mooring work equipment 53 is lower, the mooring work cannot be performed in the recess 27.

More preferably, as shown in fig. 2 (a), the maximum value of the height H of the recess 27 is less than the height H0 of the ceiling 47 of the deckhouse 23 above the recess 27, and the deckhouse 23 above the recess 27 constitutes the ceiling 27b of the recess 27.

In this configuration, since the recess 27 has the ceiling plate 27b, the deckhouse 23 above the ceiling plate 27b can be used as a residential area, and the floor area of the residential area is wider.

Further, since the equipment necessary for the work on the exposed deck 61 other than the mooring work is suspended from the ceiling plate 27b, it is not necessary to provide a place for installing the equipment on the exposed deck 61, and it is easier to enlarge the floor area of the residential area.

The maintenance of the lateral thruster 33 is exemplified as an operation on the bare deck 61 other than the mooring operation.

In this case, as shown in fig. 3, the top plate 27b of the recess 27 includes a holding portion 73 that holds the side pusher 33 detached from the duct 51 in a suspended state.

The holding portion 73 is a hanging tool, and includes an engaging member such as a hook that holds the side thruster 33, and further includes a winch that moves the engaging member up and down as necessary.

In this configuration, as shown in fig. 4, at the time of maintenance of the side thruster 33, the side thruster 33 detached from the tunnel 51 is held in a suspended state by the holding portion 73 provided on the ceiling 27b of the recess 27.

This makes it unnecessary to provide a separate device for suspending and holding the detached lateral thruster 33, and therefore it becomes easier to enlarge the floor area of the residential area.

For example, when the lateral thruster 33 is serviced without the recess 27, it is necessary to provide an apparatus for suspending and holding the lateral thruster 33 like a step 71a shown in fig. 4 to the exposed deck 61. In this configuration, the side thrusters 33 are held by hooks or the like attached to the lower surface of the top plate of the step 71a, but it is necessary to secure a space in which the step 71a is disposed. Particularly, when the deckhouse 23 including the residential area and the bridge is provided in the tapered bow area 9 like the cargo ship 1, it is difficult to secure the floor area of the residential area if such a space is provided.

Therefore, by providing the holding portion 73 on the top plate 27b of the recess 27, it is not necessary to provide a space for installing the step 71a on the exposed deck 61, and it is easier to enlarge the floor area of the residential area.

The installation position can be set as appropriate as long as the deck house 23 is provided on the exposed deck 61 on the bow region 9, is provided on the bow side of the cargo region 7, and is provided with the recess 27.

However, it is preferable that the front surface 41 of the deckhouse 23 excluding the recess 27 is disposed on an exposed deck 61 on the bulkhead 31 as shown in fig. 2 (a).

In this configuration, the deckhouse 23 is disposed on the stern side of the bulkhead 31 in the ship length direction. Therefore, even in the case where the bow-side hollow space 9b located on the bow side of the crash bulkhead 31 is flooded, the flooding is blocked by the crash bulkhead 31 without flooding to the stern-side hollow space 9a located below the deckhouse 23. This can improve the safety of the living area in which the deckhouse 23 is installed, compared with the case where the deckhouse 23 is installed on the bow side of the bulkhead 31.

Further, it is preferable that the rear end 43, which is the stern-side end portion of the deck room 23 in the ship length direction, is in contact with the front end, which is the bow-side end portion, of the tank cover 19 covering the liquefied gas tank 17.

In this configuration, since the deckhouse 23 is provided forward of the tank cover 19, even if leakage of liquefied gas from the liquefied gas tank 17 occurs, the tank cover 19 can prevent leakage into the deckhouse 23, which is advantageous in that safety of the deckhouse 23 is improved.

The width W0 in the ship width direction of the deckhouse 23 shown in fig. 2 (b) is shorter than the width of the exposed deck 61 where the deckhouse 23 is provided.

However, the width W0 need not be constant. For example, as shown in fig. 2 (b), the side surface 45 of the deckhouse 23 may be provided with an inclined surface 45a formed in a tapered shape in a plan view corresponding to the width of the exposed deck 61 of the bow region 9.

By thus making the deck room 23 into a tapered shape in accordance with the shape of the bow, the width of the passage on the exposed deck 61 in contact with the side surface 45 of the deck room 23 can be secured.

The above is a detailed description of the structure in the vicinity of the deckhouse 23.

As described above, the cargo ship 1 of the present embodiment includes: a deck house 23 provided with a living area and a bridge and provided on an exposed deck 61 of the bow area 9; the mooring 29 is provided on an exposed deck 61 in front of the deckhouse 23, and the front surface 41 of the deckhouse 23 behind the mooring operating machine 53 has a recess 27.

In this configuration, the deckhouse 23 is extended to the bow side from the foothold 27a where the operator 2 operates the mooring operation machine 53, and the floor area of the residential area is secured, and the foothold 27a is provided in the recess 27 of the front surface 41 of the deckhouse 23 behind the mooring operation machine 53, thereby securing the mooring operation area.

Therefore, even when the deck house 23 including the residential area and the bridge is provided on the exposed deck 61 having a tapered shape on the bow side, the floor area of the residential area and the mooring work area can be secured.

The present invention has been described above with reference to the embodiments, but the present invention is not limited to the embodiments. It is obvious to a practitioner that various modifications and improvements can be made within the scope of the technical idea of the present invention, and these are also included in the present invention.
