Description

TECHNICAL FIELD [0001] The present invention relates to a thruster trunk hatch having a cradle function and a thruster trunk hatch having the cradle function, and a thruster maintenance apparatus including the thruster trunk hatch.

The present invention relates to a thruster trunk hatch, and more particularly to a thruster trunk hatch installed on a deck in order to cover a trunk formed in a vertical direction at a position passing through the hull for maintenance of the thruster. A thruster trunk hatch which can be used for a trunk cover before the thruster maintenance and before the thruster maintenance and for the seating of the thruster in the maintenance of the thruster, and a thruster retainer including the thruster trunk hatch Maintenance device.

Floating oil (or liquefied natural gas) production Storage and unloading facilities require heading control for smooth operation.

Production of floating oil (or liquefied natural gas) The device used to control the storage and unloading facility is a thruster.

Inboard maintenance type thruster is a type of stenter specially designed to allow thruster maintenance in crude oil (or liquefied natural gas) production storage and unloading facilities.

1 is a view for explaining a conventional thruster trunk hatch and thruster maintenance.

Referring to FIG. 1, a thruster T is installed on a ship bottom. For maintenance of the thruster T, the trunk 1 is formed at a position passing through the hull in the vertical direction.

On the deck (D), a thruster trunk hatch (10) for covering the trunk (1) is provided so as to be openable and closable.

The hull is provided with a crane (2) for lifting and horizontally moving the thruster (T) vertically and horizontally for maintenance of the thruster (T).

During the maintenance of the thruster T, the thruster trunk hatch 10 is transported and stored in a storage place, and the thruster T is raised by using the crane 2.

The thruster T is raised on the deck D and then moved in the horizontal direction.

Then, the cradle 40 is transported from the storage place to the maintenance site, placed on the deck D, the thruster T is placed on the cradle 40, and the maintenance work is performed.

However, conventionally, before the thruster maintenance, the cradle 40 is separately prepared and stored in a specific space of the hull. After the thruster maintenance, the cradle 40 is transported to the maintenance work site, It is necessary to keep cradle storage space, so space for installation of hull equipment is reduced, and cradle, which is a heavy load, must be moved several times during maintenance of thruster, .

Korean Patent Publication No. 10-2013-0104324

In order to solve the above-described problems, the present invention has a thruster support provided on an upper part of a thruster trunk hatch installed on a deck for covering a trunk formed in a vertical direction at a position passing through a hull, A thruster trunk hatch having a cradle function and a thruster trunk hatch including the thruster trunk hatch which can be used for a trunk cover and used for seating of a thruster in the maintenance of a thruster It has its purpose.

To achieve the above object, the present invention provides a thruster maintenance apparatus and a thruster trunk hatch.

First, the thruster maintenance apparatus of the present invention is a thruster trunk hatch installed on a deck for covering a trunk formed in a vertical direction at a position passing through the hull, The thruster support is installed on the upper part of the thruster trunk hatch body so that it can be used for the purpose of use.

The thruster trunk hatch of the present invention is installed on a deck to cover a trunk formed in a vertical direction at a position passing through a hull, and is provided with a thruster for use in seating the thruster during maintenance of the thruster. Thruster support is installed on the top of the trunk hatch body.

The thruster support may include a plurality of vertical support portions vertically installed on the upper surface of the thruster trunk hatch body to support the thruster, and a connection portion connecting the vertical support portions horizontally.

As described above, in the present invention, a thruster support is provided on an upper part of a thruster trunk hatch installed on a deck for covering a trunk formed in a vertical direction at a position passing through a hull, and before the thruster maintenance, It is not necessary to separately manufacture the cradle, so that it is possible to reduce the manufacturing cost of the cradle, it is not necessary to secure a place for storing the cradle, The storage space can be used for other equipment installation space.

Also, since there is no need to move the cradle, which is a heavy object, at the time of maintenance of the thrusters, safety accidents can be prevented in advance and the maintenance work can be speeded up.

1 is a view for explaining a conventional thruster trunk hatch and thruster maintenance;
2 is a view showing a state before the thruster maintenance according to the present invention;
3 is a view showing a thruster maintenance apparatus according to the present invention
4 is a view showing a thruster trunk hatch having a cradle function according to the present invention

Hereinafter, a thruster trunk hatch having a cradle function according to the present invention and a thruster trunk hatch including the thruster trunk hatch will be described in detail with reference to the accompanying drawings.

FIG. 2 is a view showing a state before the thruster maintenance according to the present invention, FIG. 3 is a view showing a thruster maintenance apparatus according to the present invention, FIG. 4 is a perspective view of a thruster trunk Fig.

2 to 4, the thruster maintenance apparatus of the present invention includes a crane for lifting and vertically moving the thruster T in the horizontal direction for maintenance of the thruster T to the hull, (2).

A trunk 1 is formed in a position perpendicular to a position passing through the hull and a thruster trunk hatch 100 is provided so as to be openable and closable to cover the trunk 1 on the deck D.

In maintenance of the thruster T, the thruster trunk hatch 100 has a cradle function so that it can be used for the purpose of seating the thruster T. That is, the thruster trunk hatch body 110 has a function of covering the trunk 1, and a thruster support 120 is formed on the upper part of the trruster trunk hatch body 110.

The thruster support 120 includes a plurality of vertical support portions 121 vertically installed on the upper surface of the thruster trunk hatch body 110 to support the thruster T, And a connecting portion 122 for connecting the connecting portion.
