Description

[0001] HELDECK INCLUDING EXTENDED PLATFORM [0002]

The present invention relates to a helideck with an expansion platform.

Generally, offshore plants such as drill ship, FPSO (Floating, Production, Storage and Offloading) or vessels that need to stay in the sea for a long time should operate helicopter , Which necessitates the installation of Helideck on the player or stern.

The helideck may be comprised of a pancake portion forming a deck floor where the helicopter takes off and landing and a pancake support portion supporting the pancake portion. The pancake part may be formed by connecting a plurality of plank to each other so as to support the helicopter. The pancake support may include H-shaped beams capable of supporting the pancake portion.

For example, the pancake portion may be formed by connecting a plurality of flank of aluminum material extending in one direction. Further, the pancake supporting portion includes a plurality of aluminum H beams extending long in a direction intersecting the extending direction of the flanks and disposed below the flanks to support the pancake portion, an aluminum H beam extending long in a direction intersecting the extending direction of the aluminum H beam, And a plurality of steel H beams disposed below the beam to support the aluminum H beam.

On the other hand, in the case of a helideck provided on a marine structure or a ship, only one can be provided because of spatial restrictions, so that only one landing can be made at a time. Therefore, when there are several helicopters to be landed, a helicopter requiring landing has to wait in the air until the already landed helicopter leaves the helideck, so that the helicopter is provided to the offshore structure or the ship and several helicopters land at once The need for a helideck that can be done is raised.

Further, there is a problem that when the helicopter breaks down or lands after the landing of the helideck, or when an accident occurs, the helideck is already occupied by the helicopter and can not be used anymore.

Through this process, the expansion platform 200 can be fastened to the pancake unit 100, and the expansion platform 200 can be detached and attached as needed, so that the space can be efficiently used, There is an effect that detachment is possible by a simple method.

In this manner, the helicopter landed on the expansion platform 200 assembled to the helideck 10 or a helicopter landed on the top surface of the pancake 100 may be stored.

More specifically, the first helicopter H1 may include a landing wheel. When the first helicopter H1 is already landed on the pancake unit 100, the first helicopter H1 may be transported to any one of the expansion platforms 200 by a separate transport vehicle, And can be seated on the storage portion 210 of the expansion platform 200.

Thereafter, the second helicopter (H2) can land on the top surface of the empty pancake unit (100).

It is also possible for the second helicopter H2 to directly land on the expansion platform 200 with the first helicopter H1 landing on the pancake unit 100. [

The first helicopter H1 and the second helicopter H2 can land on the helideck 10 at the same time and the helicopter can be landed one more than the number of the expansion platforms 200 by the above- There is an effect that a plurality of helicopters can be landed by the expansion platform 200 in spite of the constraints of the helicopter.

Hereinafter, a second embodiment of the helideck according to the present invention will be described with reference to FIGS. 5 and 6. FIG. This embodiment differs from the first embodiment in terms of the structure of the expansion platform 300 and will be described mainly on the basis of the differences and will be described with reference to the same portions and reference numerals.

FIG. 5 is a cross-sectional view illustrating a helideck according to a second embodiment of the present invention, and FIG. 6 is a cross-sectional view illustrating the extension platform of FIG. 5 slidably protruding from the pancake portion.

The present embodiment is different from the first embodiment in that the expansion platform 300 is not detachably provided but is inserted into the inside of the pancake unit 100 and is slid by the conveyance unit 340 when necessary So that it can be projected to the outside.

5 and 6, the expansion platform 300 includes a storage unit 310 corresponding to the upper plate, a transfer unit 340 corresponding to the lower plate, a support unit 310 provided between the storage unit 310 and the transfer unit 340, The supporting part 330 is connected to the storage part 310 by the upper truss 312 to support the storage part 310 and is connected to the transfer part 340 by the lower truss 314 And can be supported by the transfer unit 340.

The illumination unit 320 may be provided along the rim of the storage unit 310 and a plurality of illumination lamps 322 may be provided inside the illumination unit 320. [

A rack 344 for conveying the expansion platform 300 may be formed on the lower surface of the transfer unit 340 and a rack 344 may be installed on both edge portions of the transfer unit 340. The rack 344 may be provided so as to be slidable in the left and right directions by engaging with the wheel 114 formed on both edge portions of the upper surface of the pancake support portion 104. [

When a plurality of helicopters need landing on the helideck 10 having the expansion platform 300 according to the present embodiment, the rack 344 of the expansion platform 300 is guided by the wheel 114, The platform 300 may slide to protrude outside the pancake portion 100. After the helicopter landed on the extensible platform 300, the helicopter awaiting landing in the air can safely land on the upper surface of the pancake part 100 where the air is empty.

At this time, the stopper 311 may protrude upward from the side end of the storage unit 310 of the expansion platform 300 facing the center of the helideck 10. In addition, a stopper 116 may protrude downward from the side end of the pancake 102 facing the outside.

The stopper 311 of the storage part 310 and the stopper 116 of the pancake 102 come into contact with each other when the expansion platform 300 slides and the storage part 310 protrudes to the extent that the helicopter can be stored. The sliding can be prevented.

The supporting beam 346 coupled to the hinge 342 provided on the lower surface of the transfer unit 340 can be coupled to the hinge 112 attached to the end of the deck support unit 106. [ The hole formed at one end of the support beam 346 and the hole formed in the hinge 112 of the deck support unit 106 are aligned and the pipe is inserted into the hole and the support beam 346 and the hinge 112 are fastened .

In addition, when the sliding is completed, the upper surface of the storage part 310 and the upper surface of the pancake 102 may not coincide with each other. In this case, it may be difficult to transfer the helicopter that has landed on the pancake unit 100 to the storage unit 310. Therefore, when the extension platform 200 is completely projected, as shown in FIG. 6, ramp 118 is installed on the storage part 310 so that the helicopter can be easily transferred to the storage part side.

Although the embodiments of the helideck according to the embodiment of the present invention have been described above, the present invention is not limited thereto, and the present invention is not limited thereto and should be construed as having the widest range according to the basic idea disclosed in this specification . Skilled artisans may implement a pattern of features that are not described in a combinatorial and / or permutational manner with the disclosed embodiments, but this is not to depart from the scope of the present invention. It will be apparent to those skilled in the art that various changes and modifications may be readily made without departing from the spirit and scope of the invention as defined by the appended claims.
