Description

Helideck {Helideck}

The present invention relates to a helideck, and more particularly, to a helideck installed on a ship.

Most large ships and offshore structures, such as drillships, are equipped with Helideck, which provides landing surfaces for helicopters to land and land for emergency and, if necessary, transport of life and materials. The helideck is generally installed in the upper area of a structure such as a deckhouse.

These heli-decks are often not used during a voyage or during off-shore operations where helicopter landings and landings are not required during sea voyage.

 In addition, during the voyage of the ship or offshore structure, wind load caused by the wind blowing toward the structure acts on the structure where the helideck is installed. Because of such wind loads, the resistance of ships or offshore structures increases, resulting in energy losses.

Referring to FIG. 4, the helideck 10 according to the present embodiment includes a base driver 300. The base driving unit 300 provides a driving force such that the base deck 100 operates in a horizontal or inclined manner.

For example, the base driving unit 300 may include a hydraulic cylinder 320 that extends and retracts to rotate the base deck 100, as shown in FIG.

The hydraulic cylinder 320 may be interposed between the base deck 100 and the structure 30, but may be variously arranged such that the base deck 100 is rotatable.

FIG. 5 is a view showing a helideck of FIG. 1 operating in an inclined manner forward and downward, and FIG. 6 is an enlarged perspective view of the helideck of FIG.

Hereinafter, the operation of the helideck 10 according to the present embodiment will be described with reference to FIGS. 1, 5, and 6. FIG.

1, the helideck 10 according to the present embodiment provides a landing surface for a helicopter (not shown) to take off and land for transportation of persons or goods when the ship 1 is in voyage or berth Needs to be.

In this case, the base deck 100 operates to maintain a level and provides a landing surface.

The size of the base deck 100 can be determined according to the size of the landing helicopter.

Referring to Figures 5 and 6, when the vessel 1 is navigating, the helideck 10 may operate to reduce wind loads acting on the structure 30 when it is not necessary to provide a landing surface.

In this case, the base deck 100 is inclined forwardly below the structure 30.

At this time, the base deck 100 and the extension deck 200 form a wedge-like shape on the upper surface side of the hull 20 as shown in FIG. 6 and can cover the front surface of the structure 30.

The base deck 100 and the extension deck 200 allow the wind blowing toward the structure 30 to be deflected along the slope formed by the base deck 100 and the extension deck 200.

More specifically, when the base deck 100 is inclined down the front of the structure 30, a portion of the wind directed toward the front of the structure 30 rides over the inclined plane formed by the base deck 100, Moves to the path. A part of the wind directed toward the front of the structure 30 moves laterally of the structure 30 on an inclined surface formed by the extension deck 200.

In this case, the base deck 100 and the extension deck 200 reduce the wind load acting on the structure 30 by switching the direction of wind movement toward the structure 30 from the front of the structure 30. [

Therefore, the resistance of the hull 20 due to wind is reduced, and the propulsion efficiency is improved.

The angle formed between the extension deck 200 and the base deck 100 may be determined in consideration of the size of the structure 30 to be covered when the base deck 100 is inclined.

FIG. 7 is a view showing a modified example of the base driving unit shown in FIG. 4, and FIG. 8 is a view showing a state in which the base driving unit of FIG. 7 operates so as to tilt the base deck. For reference, the extension deck (200 in Fig. 1) is omitted in Fig. 7 and Fig.

7 and 8, the base driving unit 300 'according to the present modification includes a first actuator 331 for moving up and down the front end portion of the base deck 100 and a second actuator 331 for moving the rear end portion of the base deck 100 up and down And a second actuator 332.

For example, although the first actuator 331 and the second actuator 332 may be in the form of a telescopic boom, various types of devices capable of moving up and down the front end and the rear end of the base deck 100 are proposed Of course.

7, the base deck 100 is horizontally extended or contracted by extending and contracting the first and second actuators 331 and 332, and the base deck 100 is inclined do.

In this case, the base deck 100 is disposed in front of the structure 30, away from the entire structure 30.

On the other hand, the first actuator 331 and the second actuator 332 can be expanded and contracted in accordance with the height change of the structure 30.

For example, when the height of the structure 30 is increased due to equipment installation or the like in a state where the base deck 100 is inclined, the second actuator 332 is positioned at a position where the rear end of the base deck 100 is at an increased height As shown in Fig. In this case, the base deck 100 can reduce the wind load corresponding to the structure 30 having increased height.

On the other hand, the first actuator 331 and the second actuator 332 can be contracted or stretched at the same time. In this case, the base deck 100 can serve as the elevating device. For example, when the first actuator 331 and the second actuator 332 contract together when the base deck 100 maintains the horizontal position, the base deck 100 can be lowered while maintaining the horizontal position.

9 is a view showing a modification of the coupling structure of the base deck and the extension deck of Fig.

Referring to FIG. 9, the extension deck 200 of the helideck is rotatably coupled to the base deck 100. For example, the extension deck 200 may be hinged to the base deck 100.

In this case, the extension drive 220 provides a driving force for rotating the extension deck 200 relative to the base deck 100.

For example, the extension driving unit 220 may include a hydraulic cylinder 221. At this time, one end of the hydraulic cylinder 221 is supported by a support member 222 formed on the bottom surface of the base deck 100, and the other end of the hydraulic cylinder 221 is elastically coupled to the bottom surface of the extension deck 200 have.

It goes without saying that various devices for providing the driving force for rotating the extension deck 200 may be proposed as the extended driving part 220.

When the base deck 100 provides a landing surface, the extension deck 200 may rotate to be parallel to the base deck 100 about the hinge axis 210. In this case, the extension deck 200 is located on the same plane as the base deck 100 and can extend the landing surface provided by the base deck 100.

When the base deck 100 is tilted downwardly forward of the structure 30, the extension deck 200 is positioned between the extension deck 200 and the base deck 100, corresponding to the inclination angle of the base deck 100 with respect to the horizontal plane The inclination angle can be adjusted.

For example, when the rear end of the base deck 100 rises and the second actuator (332 in Fig. 7) of the base drive unit (300 'in Fig. 7) of the modification described above is extended, the base deck 100 The inclination angle formed can be increased. At this time, the extension deck 200 rotates so that the inclination angle formed by the extension deck 200 and the base deck 100 is adjusted in accordance with the change of the inclination angle of the base deck 100 with respect to the horizontal plane.

In this case, the extension deck 200 can effectively cover the front surface of the structure 30 together with the base deck 100, effectively reducing the wind load acting on the structure 30

As mentioned above, the helideck 10 according to the present embodiment can provide a landing surface on which a helicopter (not shown) can take off and land, So that it is possible to reduce the wind load acting on the structure 30, thereby improving the propulsion efficiency of the hull 20.
