Description

STRUCTURES OF HELIDECK

This invention relates to helideck structures.

In general, marine structures or some vessels that stay in the ocean for long periods, such as drillships, FPSOs, and RIG ships, must operate a helicopter to transport or transport personnel or materials, thereby requiring the installation of helidecks at the bow or stern. .

The helideck may be composed 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 For example, a part including a refueling equipment, a firefighting facility, an illumination facility, etc., and the pancake supporting part is a pancake lower supporting structure, which means an aluminum H beam at the bottom of the pancake and a steel H beam at the top of the deck supporting part And the deck support may refer to a backing structure connected to a deck house to support a heald deck which is an assembly of the pancake part and the pancake support.

The helideck is equipped with a helicopter refueling system, and a drain line is provided for discharging the fuel oil in case the fuel oil falls due to the pancake when the fuel is lubricated.

However, the existing drain line for the helicopter refueling system is configured to discharge the fuel oil directly from the pancake to the sea, and there is a problem that marine pollution and explosion accident due to fire oil may occur when the fuel oil leaks.
