Description

Ship {Ship}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ship, and more particularly to a ship in which the sway is reduced.

Recently, drilling works for underground oil fields or gas fields are actively underway.

A drill ship is specially devised for drilling operations on such submarine oil fields or gas fields.

The drill ship needs a stable posture during the drilling process. Therefore, it is urgent to develop a technique to reduce the ups and downs of the drill ship during the drilling process.

An embodiment of the present invention is to provide a ship which is configured to effectively reduce fluctuations of the hull.

According to an aspect of the present invention, there is provided a hull comprising: a hull; A horizontal plate disposed below the hull to reduce vertical movement of the hull; And a ship that houses the horizontal plate.

The hangar may be formed between an inner bottom plate and an outer bottom plate of the hull.

The horizontal plate may be combined with a first vertical plate for reducing front-rear sway of the hull and a second vertical plate for reducing lateral sway of the hull.

The horizontal board is stored at the bottom of the hull when the hull is in operation and can descend from the bottom of the hull when the hull is moored.

The ship further includes a lifting and lowering driving part for lifting and descending the horizontal plate, wherein the lifting and lowering driving part includes: a winch supported by the hull; And a connection line fixed to the horizontal plate and wound on the winch.

According to the embodiment of the present invention, due to the horizontal plate disposed in the lower water of the hull, the added mass for the up and down movement of the hull can be increased, so that the vertical movement performance of the hull can be improved.

Furthermore, the first vertical plate and the second vertical plate are installed on the horizontal plate to effectively reduce the fore-and-aft shake and the lateral shake of the hull.

BRIEF DESCRIPTION OF THE DRAWINGS The present invention is capable of various modifications and various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Referring to the accompanying drawings, the same or corresponding components are denoted by the same reference numerals, do.

1 is a view showing a ship according to an embodiment of the present invention. Referring to FIG. 1, the ship 100 according to the present embodiment includes a ship 110 and a horizontal plate 130, and is a ship in which the sway is reduced. For reference, the rightward direction in FIG. 1 represents the front of the ship 100.

In this embodiment, the vessel 100 is a drill ship that drills a submarine oil field or a gas field.

The hull 110 is provided with a door 111 for descending a riser (not shown) for drilling, and various equipment (not shown) for drilling are installed. An omni-directional propeller 121 is installed in the hull 110 to control the dynamic position of the ship 100.

A hangar 112 is formed at the bottom of the hull 110. The hangar 112 provides a space for storing a horizontal plate 130, which will be described later. The hull 110 may have a double hull structure. At this time, the hangar 112 may be formed between the inner bottom plate 113 and the outer bottom plate 114 of the hull 110. In this case, space utilization of the hull 110 is improved.

A door 115 may be provided at the entrance of the hangar 112. The door 115 closes the inlet in a state in which the horizontal plate 130 is stored in the hangar 112 and opens the inlet in the process of descending the horizontal plate 130.

The horizontal plate 130 is disposed below the hull 110 to reduce the vertical movement of the hull 110. The horizontal plate 130 is accommodated in a hangar 112 formed in the hull 110 in the course of the movement of the ship 100 and is disposed on the lower side of the hull 110 in the drilling operation or in the hangar 112 .

The horizontal plate 130 disposed in the water below the hull 110 has a flat shape in the horizontal direction. In this case, the additional mass of the hull 110 is increased with respect to the up-and-down movement, and the vertical movement performance of the hull 110 is improved.

The vessel 100 further includes an elevation driving unit 150 for elevating and lowering the horizontal plate 130.

In this embodiment, the lifting and lowering driving unit 150 includes a winch 151 and a connecting line 153. The winch 151 is supported by the hull 110. For example, the winch 151 may be disposed inside the hangar 112. The connecting line 153 is fixed to the horizontal plate 130 and is wound by the winch 151. [ The connecting line 153 may comprise a wire, rope or chain.

The lifting and lowering unit 150 lifts the horizontal plate 130 in such a manner that the winch 151 winds or loosens the connection line 153.

It is needless to say that various types of lifting and driving parts 150 may be proposed although not shown in the figures.

FIG. 2 is a view for explaining an operational process of a ship according to an embodiment of the present invention.

The operation of the ship 100 according to the present embodiment will be described with reference to Figs. 1 and 2. Fig.

Referring to FIG. 1, the vessel 100 is operating as a drill ship in a target sea. In this case, the horizontal plate 130 is not exposed to the outside while being stored in the hull 110. The horizontal plate 130 stored in the hull 110 does not affect the resistance performance of the hull 110. [

Referring to FIG. 2, the vessel 100 reaches a target sea and is performing a drilling operation. In this case, the horizontal plate 130 stored in the hull 110 descends and is disposed below the hull 110. The added mass of the up and down movement is increased by the horizontal plate 130 disposed in the lower side of the hull 110 and the vertical movement performance of the hull 110 is improved. Therefore, the vessel 100 can stably perform the drilling operation in a state in which the up-and-down movement is remarkably reduced.

FIG. 3 is a view showing a ship according to another embodiment of the present invention, and FIG. 4 is a top view of the horizontal plate shown in FIG.

3 and 4, the ship 200 according to the present embodiment includes a hull 110, a horizontal plate 130, an elevation driving unit 150, a first vertical plate 141, And a vertical plate 142.

The ship 200 according to the present embodiment is different from the ship 100 according to the previous embodiment in that it includes a first vertical plate 141 and a second vertical plate 142.

The first vertical plate 141 is coupled to the horizontal plate 130 to reduce back and forth shaking of the hull 110.

The first vertical plate 141 is coupled to the upper surface of the horizontal plate 130, and one side of the first vertical plate 141 faces forward or rearward.

The second vertical plate 142 is coupled to the upper surface of the horizontal plate 130, and one side of the second vertical plate 142 faces the left or right room.

The first vertical plate 141 and the second vertical plate 142 function as resistances when the hull 110 is shaken in the front-rear direction and the lateral direction, effectively reducing front-rear swings and side-to-side swings of the hull 110 .

On the other hand, the vessels 100 and 200 described above are drill ships. However, it is needless to say that even in the case of a general merchant line, a vibration reduction apparatus including a horizontal plate 130, an elevation driving unit 150, a first vertical plate 141, a second vertical plate 142 and the like may be applied.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, many modifications and changes may be made by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims. The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
