Description

Helideck {Helideck}

The present invention relates to a helideck, and more particularly, to a helideck installed on an offshore structure or a large ship.

In general, offshore structures such as Wind Turbine Installation Vessel (WTIV), Drill ship and FPSO (floating production storage and offloading), or vessels staying in the sea for long periods of time, require a helicopter to transport various materials or personnel. Helideck for the takeoff and landing of the helicopter shall be installed on the athlete or ship's athlete or ship.

Therefore, since the helideck is exposed to the sea conditions with relatively high wind speed and high wind speed, it is not possible to safely store the helicopter landed on the helideck, and in particular, maintenance work on the helicopter is difficult.

That is, in order to maintain the helicopter landed on the heli-deck, the operator must go directly to the helideck exposed to the outside environment and then perform the maintenance work on the helicopter. In this case, , And the maintenance work itself is difficult when the marine climate conditions are not very good.

Accordingly, there is a need for a helicopter to safely store the helicopter in a state where the helicopter is landed, as well as to facilitate maintenance work on the helicopter.

In this state, as shown in FIG. 5, when the elevating plate 210 is lowered by driving the elevating device 220 and then the upper cover 230 is rotated and closed as shown in FIG. 6, The helicopter H is located in the lower space of the hangar 200 between the fixed decks 110 of the helideck 100 so that exposure from the outside can be limited.

7, guide projections 212 or guide grooves are formed on both side surfaces of the lifting plate 210. The guide protrusions 212 or the guide grooves are formed on both sides of the hangar 200 The lifting plate 210 can be stably lifted and held in a state of being kept horizontal.

When the operator enters the hangar 200 and performs the maintenance work on the helicopter H in a state where the helicopter H is disposed in the hangar 200 as described above, The maintenance work can be easily performed, so that the risk of safety accidents may be reduced.

When the upper cover 230 is closed and the upper space of the hangar 200 is closed while the lifting plate 210 is lowered, the upper surface of the upper cover 230 is flush with the upper surface of the fixed decks 110 It is possible to perform a bridge function of connecting between the fixed decks 110 disposed side by side so that the operator can easily move between the fixed decks 110 on both sides .

In the case of the helideck 100 according to the first embodiment of the present invention, the shield plate is formed on the front or rear side of the lifting plate 210, It is possible to minimize exposure from the external environment in a state of being lowered to the lower space of the main body 200.

In other words, both sides of the lifting plate 210 must be formed in an open structure by forming a moving space of the helicopter H to be transported from both the fixed decks 110, but the helicopter H It is not necessary to secure a moving space of the front cover or the rear cover.
