Description

{Lamp unit for landing induction of helicopter at night and induction device for landing helicopter at night using the same}

The present invention relates to a helicopter night landing induction lamp unit and a helicopter night landing induction device using the same, and more specifically, a helicopter night landing for guiding a helicopter to a helicopter deck installed on a floating structure such as a ship floating at night. It relates to an induction lamp unit and a helicopter landing guidance device using the same.

In general, offshore plants, such as drill ships or floating, production, storage and offloading (FPSO), or ships that need to stay for a long time on the sea, must operate a helicopter to move personnel. For this reason, it is necessary to install a Helideck on the bow or stern.

The heli deck may be generally composed of a pancake portion forming a deck floor in which the helicopter takes off and landing, and a pancake support portion supporting the pancake portion. The pancake portion may be formed by connecting a plurality of flanks to support the helicopter. The pancake support portion may include H-shaped beams capable of supporting the pancake portion.

On the other hand, when the helicopter is operated at night, the perimeter light that irradiates light upward to outline the heli deck to assist landing when operating the helicopter at night, and irradiates light to the side for the helicopter's embarkation. A light such as a Floodlight is installed.

However, it is difficult for the pilot of the helicopter to determine the correct landing position because the H mark and the touch down/positioning making circle painted on the upper part are not clearly revealed with only the perimeter light and the flood light. There was. As a method to improve this problem, the H mark and the touch-down/positioning marking circle are more clearly formed by additionally inserting and installing a buried illuminator at the bottom of the H-mark to irradiate light above the Helideck. It is configured to be exposed.

However, the lighting composed of the conventional heli-deck is only on/off (On/Off) for the purpose of allowing the pilot of the helicopter to estimate the exact landing position by making the H mark and the touch-down/positioning marking circle more clearly visible. Since it is provided only as a function of driving simple lighting, it has limitations in its use.

In particular, in the case of a heli-deck operating at sea, it is very difficult to safely land the helicopter on the heli-deck, as the helicopter is horizontally and vertically moved, as well as the impact of the helicopter. In reality, it is difficult to fine-tune the movement of a floating structure or a ship with a helicopter deck for helicopter landing, and it is currently dependent on the helicopter pilot's control ability.

However, because the conditions of the sea are basically strong winds, and the waves are not only strong, but also have a rapidly changing characteristic, it is not easy to safely cope with an unexpected situation, no matter how skillful a pilot is. In particular, the risk increases further when the weather conditions are poor or at night.

Therefore, when the helicopter lands on a heli-deck operated at sea at night, an additional device capable of assisting in safer landing is required.
