Description

Helideck {HELIDECK}

The present invention relates to a helideck, and more particularly, to a helideck capable of efficiently controlling a temperature change due to heat generation of a lighting apparatus.

Helidecks are structures provided to offshore structures for helicopter landing / landing. Helideck is applied to various marine structures such as drill-ship, FLNG (Floating Liquid Natural Gas Plant) and Floating Production Storage Offloading (FPSO).

In the case of poor visibility conditions such as cloudy weather, nighttime, and bad weather (fog, strong wind), helicopter landing accident that helicopter does not land properly causes damage to people and facilities. Recently, in order to solve such a problem, the safety standard for the lighting equipment installed in the helideck is strengthened.

According to the recently revised standard, it is recommended to provide LED (Light Emitting Diode) lighting equipment in the "H" area of the helideck and in the circle area around the "H" area. Conventional lighting equipment is exposed to the top of the helideck to ensure structural stability during landing / landing of the helicopter. Therefore, not only does it act as an obstacle in the landing of the helicopter, but also breakage of the lighting equipment frequently occurs. In addition, the conventional helideck lighting equipment is deteriorated in lighting performance due to heat generation, and may fail to exhibit the lighting function in bad conditions such as bad weather. Also, the life of the lighting equipment can be shortened by the heat of the lighting equipment.

An object of the present invention is to provide a helideck capable of efficiently controlling a temperature change due to heat generation of a lighting apparatus while securing structural stability during landing / landing of the helicopter.
