Abstract

PURPOSE:To provide a ship's dodger structure having the capability of isolating the effect of an accommodation and a navigation bridge such as a natural frequency on a dodger, and applying a lightweight design and a unitized system. CONSTITUTION:A platform 15 and a catwalk 16 constituting a dodger 10 is independently supported on an upper deck 12. In this case, the dodger 10 is slightly separated from an accommodation upper structure 13 and a navigation bridge 14 via a small gap 29. As a result, the dodger 10 becomes free from an effect due to the natural frequency of the accommodation upper structure 13 and the navigation bridge 14, and can be made lightweight or unitized as an independent structure. Furthermore, the dodger 10 can be easily installed to cope with an intended purpose simply by changing the length of the catwalk 16 and the height of supports 17 and 19 thereof, regardless of a ship's size.

2. Description of the Related Art Ships, especially large ships, are constructed with a living area superstructure and a voyage bridge on the upper deck. Dodgers are provided on both sides of the voyage bridge to monitor the port side. Has been.

A conventional Dodger structure is constructed, for example, as shown in FIG. 4, by stacking a living area upper structure 3 and a navigation ship bridge 4 on an upper deck 2 of a ship 1, and a navigation ship bridge deck 5
Dodger 6 by protruding to the port side so that it is flush with
Is provided and is integrally formed with the voyage bridge 4 and the accommodation area 3, and a pillar 7 is provided at the bottom of the dodger 6 and supported by the upper deck 2.

[0004]

Problems such as the Dodger 6
In the above, since the living area superstructure 3 and the navigation boat bridge 4 have an integral structure, they are affected by the natural vibration of superstructures such as the living area superstructure 3 and the living area superstructure 3
Since it is necessary to take measures against longitudinal vibration of the upper part of the ship, a dodger support deck 8 must be provided between the back part of the dodger 6 and the rear part of the navigation deck 5 and the structure is complicated and the size of the ship changes. There is a problem that the Dodger 6 must be newly designed each time.

Further, when a ship is constructed, the upper structure 3 of the living area of 5 to 6 layers and the navigation bridge 4 are collectively mounted on the upper deck 2 as one block. 7 and the Dodger support deck 8 are restoration blocks, and it is necessary to mount them later and connect them. Since welding work onboard occurs, the Dodger 6 is installed at a height of about 15 m above the upper deck 2, There is a problem that a lot of work in high places is required for installation.

Further, it is necessary to make the Dodger 6 a vibration-proof structure, which causes a problem that the weight increases and the material cost and the processing cost increase.

The present invention has been made in view of the above problems of the prior art, and is capable of insulating the influence of natural vibrations from the living area and the navigation bridge to the Dodger, and also aiming at weight reduction and unitization. Therefore, the present invention aims to provide a ship Dodger structure that can be handled by a single module regardless of the size of the ship.

[0008]

In order to solve the above problems, the structure of the Dodger for a ship according to the present invention comprises a Dodger unit composed of a port side monitoring platform and a walkway provided between the platform and the navigation bridge. It is characterized by being formed on the upper deck independently of the residential area and the voyage bridge.

[0009]

[Operation] According to this ship's dodger structure, the platform and walkway forming the dodger are independently supported on the upper deck, and separated from the superstructure such as a living quarter or a navigation bridge with a slight gap. In this way, it is possible to reduce the influence of the natural vibration of the upper structure, reduce the weight and unitize it as an independent structure, and just change the length and height of the walkway regardless of the size of the ship. It is designed so that it can be easily installed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. 1 to 3 relate to an embodiment of a ship Dodger structure of the present invention. FIG. 1 is a perspective view, FIG. 2 is a plan view, and FIG. 3 is a sectional view taken along line AA in FIG.

In the dodger 10 of this ship, the living area upper structure 13 mounted on the upper deck 12 of the ship 11, the navigation bridge 14 and the dodger 10 are independent structures.

This Dodger 10 includes a platform 15 for port side monitoring, and a walkway (flying passage) 16 having one end connected to the platform 15 and the other end disposed with a slight clearance with the navigation bridge 14. Posts 17 and stays 18 that support the platform 15
And a stay 19 supporting the walkway 16 and a stay 20 are configured in a gate shape.

Also, in this Dodger 10, the upper deck 12
Platform 1 for port side monitoring when installed on top
Two columns 17, 19 and two stays 1 in advance so that 5 and the walkway 16 are flush with the voyage bridge deck 21.
The lengths of 8 and 20 are set and attached, and the length of the walkway 16 is also set and attached so that the outside of the platform 15 coincides with the port side.

The port side monitoring platform 15 includes:
Various equipment necessary for maneuvering is unitized in advance and equipped. For example, installation of a gyro repeater 22, a quick-drop life-saving buoy 23, a floodlight 24, an onboard communication device 25 such as a microphone jack, and the installation of wire cables are factories It has been completed with.

Further, a navigation light (port light) 26 and a platform 27 for navigation lights are provided in the middle stage of the support 17 on the port side.
Is attached, and the platform 27 has a vertical ladder 2
8 is equipped, and can be moved up and down from the upper deck 12 with the dodger 10 installed on the upper deck 12.

The dodger 10 thus unitized into a self-supporting structure is mounted on the upper deck 12 of the ship 11 with the living area upper structure 13 and the navigation bridge 14 and then lifted by a crane or the like to be placed on the upper deck 12. It is mounted at a predetermined position and the columns 17, 19 and stays 18, 20 are fixed by welding or the like. At this time, the end of the walkway 16 of the Dodger 10 and the deck 21 of the nautical boat are not directly fixed but attached so as to have a gap 29 of about 10 mm.

According to the structure of the dodger 10 of the ship thus constructed, the living area upper structure 13 or the navigation bridge 14 and the dodger 10 are installed separately from each other. Since the vibration is not directly transmitted to the Dodger 10, a vibration proof structure is not required, and the structure can be simplified and the weight can be reduced.

Further, since the Dodger is a gate type self-supporting type, it can be installed independently of the living area upper structure 13 and the voyage bridge 14, so that outfitting and electric wires necessary for maneuvering, drainage pipes, etc. Can be unitized and pre-mounted.

Further, since the dodger 10 may be unitized and completed in advance and then mounted on the upper deck 12, it is connected to the living area upper structure 13 and the navigation bridge 14 after mounting the dodger 10 which has been conventionally required. No work at a high place for repairing, restoration work, and painting work are required, and welding work for attaching the columns 17, 19 and stays 18, 20 on the upper deck 12 is all that is required, and the installation work can be performed safely and easily.

Even if the ship 11 is changed, the length of the walkway 16 and the lengths of the columns 17 and 19 can be easily adjusted by adjusting the position of the dodger 10. If the maximum width of 11 and the outer wall width of the living area superstructure 13 and the navigation ship bridge 14 are determined, it can be determined from the difference.
The length of 7, 19 is the residential area superstructure 13 and the sailing bridge 1.
It can be determined by the total number of decks of 4 and the height of one layer. This makes it possible to unify and modularize the other dimensions that make up the Dodger 10, eliminating the need to design for each ship, for example, from a large ship from 80,000 to 450,000 deadweight tons. It can easily handle huge ships.

The present invention is not limited to the above-mentioned embodiments, and each constituent element may be modified within the scope of the invention.

[0022]

As described above in detail with reference to the embodiment, according to the ship's dodger structure of the present invention, the platform and the walkway constituting the dodger are independently supported on the upper deck, and the habitat is occupied. Since it is installed separately from the upper structure such as the ward and nautical bridge with a small gap, it becomes an independent structure that is not affected by the natural vibration of the upper structure, and the vibration-proof structure is unnecessary and the weight is reduced. In addition to being able to be unitized, it can be easily installed by simply changing the length and height of the walkway regardless of the size of the ship.

Also, the loading and mounting work of the Dodger on the ship can be easily performed.
