Description

{APPARATUS FOR MANAGING HELI-DECK}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a maintenance device for a helideck, and more particularly, to a maintenance device for a helideck capable of effectively performing maintenance on a pancake support portion close to a joint portion of the pancake support portion.

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.

The helideck having the above configuration is installed in a floating state in the air at a distance from the moving body of the floating structure and the hull of the ship to secure the safety of the operation of the helicopter.

If the helideck is used for a long time at sea, it is inevitably exposed to problems such as corrosion and abrasion, and it may be damaged by the impact caused by the takeoff and landing of the helicopter. In the event of such a problem, the helideck needs maintenance such as replacement and repair.

Maintenance of the heli-deck can be done either by replacing the heli-deck as a whole or by repairing the problem area. In the former case, however, it is difficult to expect the same stability as in the first installation because the economical efficiency is low and the operation is very difficult. In the latter case, since the helideck is installed in a floating state in general, There is a problem that the operation must be performed under conditions that are practically impossible or possibly very dangerous.
