The underwater barge for the installation of the azimuth thruster comprises a frame; a plate installed on the frame and having the azimuth thruster on the surface; a buoyancy controlling unit installed on the frame; multiple thrusters installed on the frame; a camera combined to the frame; and a controller controlling the buoyancy controlling unit, the multiple thrusters, and the camera.

Description

{Underwater barge to install Azimuth Thruster}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater barge that can easily install a swing propeller on a special ship such as a drill ship.

In general, the azimuth thruster can be installed on a special ship such as a drill ship to maintain the position and posture of the hull stably. Such a pivoting propeller can be installed on the drill ship below the surface of the drill ship. In other words, after placing the propeller on the sea floor with constant water depth and moving the ship to the upper side of the propeller, the ship can be installed on the vessel by using the wire rope to raise the propeller.

The method of installing such a tilting propeller has a problem that it requires a certain depth of water to install the tilting propeller, which limits the working space.

In addition, since the ship must be moved repeatedly in order to install the spinning type propeller, the working time is increased and the installation cost of the spinning type propeller is increased.

Accordingly, the present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a ship capable of reducing the installation space, And to provide an underwater barge for installation of a salvage propeller.

According to an aspect of the present invention, A platen mounted on the frame, on which the pivoting propeller is mounted; A buoyancy adjusting unit installed in the frame; A plurality of propellers installed in the frame; A camera coupled to the frame and a controller for controlling the buoyancy regulator and the plurality of the propellers according to an input signal to align the propulsion system with the bottom propeller engagement position on the bottom, .

The propeller can be driven forward and backward under the control of the controller.

And a connecting member provided on one side of the frame in a direction perpendicular to the base, wherein the camera is an underwater camera coupled to the connecting member.

Preferably, the controller is disposed in a control room installed on the land and is connected to the buoyancy control unit, a plurality of the propellers, and the camera by wire or wireless.

The present invention has the effect of reducing installation time and installation cost because it is relatively free from the restriction of the installation location by installing the pivoting propulsion unit using the underwater barge while the drill ship is stopped without moving.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view showing an example in which a swing line propulsion unit is installed to illustrate an embodiment of the present invention.
2 is a view showing an underwater barge line for explaining an embodiment of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

FIG. 2 is a perspective view for explaining an embodiment of the present invention. FIG. 2 is an exploded perspective view of an embodiment of the present invention. And an underwater barge line (B).

The underwater barge line B for installing the swing type propulsion device of the embodiment of the present invention includes the frame 1, the table 3, the buoyancy adjusting unit 5, the propeller 7, the camera 9, and the controller 11 do.

The frame 1 may be a frame of underwater barge B and may include a space in which the buoyancy regulating part 5 can be installed. The outer shape of the frame can be made entirely streamlined or shaped like a normal barge.

A base (3) is provided on the upper part of the frame (1). The surface plate 3 can be made of a flat plate and a tilting propeller (A, shown in Fig. 1) is raised.

The buoyancy control unit 5 may be connected to the controller 11 by a cable C or may be wirelessly controlled to float or submerge the underwater barge on the water. The buoyancy control unit 5 can prevent the underwater barge from sinking in water under the control of the controller 11.

A plurality of propellers 7 are installed on the upper side or the side of the frame 1. The propellers 7 are controlled by the controller 11 and can be rotated forward or reverse to move the underwater barge or maintain the posture.

In the embodiment of the present invention, the propeller 7 has been described as being rotated in the forward or reverse direction. However, the structure in which the propeller 7 itself can change its direction is employed and serves as a driving source capable of freely moving the underwater barge It is possible.

The connecting member 13 is vertically coupled to the side surface of the frame 1. [ The connecting member 13 is provided with an underwater camera 9. The camera 9 is connected to a display (not shown) and can output an image photographed by an external camera 9.

The camera 9 may also be connected to the controller 11 to rotate in various directions and transmit the underwater situation to the display.

The controller 11 is preferably installed on land. That is, the control room CR can be installed on the land, and the controller 11 can be installed in the control room CR. The controller 11 can control the buoyancy control unit 5, the propeller 7, the camera 9, and the like described above by wire or wireless, as described above.

A process of installing the azimuth thruster (A) on the drill ship according to the embodiment of the present invention will be described as follows.

The pivoting propeller (A) is placed on the base (3) of the underwater barge (B) through a crane on the ground or a crane on the barge. Then, the operator controls the buoyancy control unit 5 and the propeller 7 by the controller 11 to move the underwater barge in water.

At this time, the worker can confirm the internal situation of the water by using the water-powered camera 9. [ Subsequently, the underwater barge is moved and moved to the installation position of the pivot propeller (A) of the drill ship (D).

Then, the diver attaches and lifts the propulsion unit (A) to the crane provided in the drill ship and assembles the propulsion unit on the drill ship.

In this method, it is not necessary to calculate the drop position of the propulsion system of the ship which is moored on the existing quay wall, and it is not necessary to move the vessel to release the propulsion system.

Therefore, it is possible to easily install the propulsion unit, reduce the working time, and significantly reduce the use time of the quay wall, thereby reducing the installation cost.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And it goes without saying that the invention belongs to the scope of the invention.
