SYSTEM FOR EMERGENCY ESCAPE USING HELIDECK [0002]

The present invention relates to an emergency escape system using a helideck.

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.

Here, the plank means an aluminum extruded material having a trapezoidal cross section, the pancake means an upper plate (take-off and landing surface) formed by connecting flanks, the pancake means a pancake made of flanks, and other helidecks And the pancake supporting portion may be an aluminum H beam on the bottom surface of the pancake and a steel H beam on the deck supporting portion, May refer to a backing structure connected to a deck house to support a heli deck that is an assembly of pancake and pancake supports.

The helideck is installed in a floating state with a certain distance from the body of the floating structure and the hull of the ship to secure the safety of helicopter operation. Helidecks are inevitably subject to corrosion, abrasion, and other problems when used for a long time at sea.

The steel H beam corresponding to the lower end portion of the pancake support portion and the aluminum H beam corresponding to the upper end portion of the pancake support portion are coupled to each other at the intersection point. Since the dissimilar metal is a kind of dissimilar metal, It is necessary to take measures against galvanic corrosion.

The helideck, which is a background of the invention, is usually provided to operate a helicopter in the concept of an offshore structure including a ship. Such an offshore structure is provided with a life preserver capable of escaping the shipowner in the event of an emergency (for example, A boat, and the like.

However, the number of rescue boats is significantly short compared to the number of resident in the offshore structure, so there is no practical and active measure for escaping large numbers of personnel in case of an emergency.
