Winching Area ^
General
11 (1) All helicopter operations to and from a ship should normally involve landing on a deck; however, where operations are infrequent or the configuration of the ship precludes installation of a helicopter deck, then facilities for winching may be provided.
(2) The location of the winching area should take into account ship motion, turbulent wind conditions owing to superstructures, funnel exhaust gases and any restrictions and obstacles to approach areas.
(3) Winching operations may be carried out above cargo areas on oil tankers, chemical tankers and gas carriers, provided the ship’s tanks beneath the winching area are inerted and tested to confirm that their atmospheres are below the explosive limit.
(4) Winching operations should not be carried out above cargo areas of ships in which dangerous goods are stored, as defined in the Transportation of Dangerous Goods Regulations.
Deck area ^
(5) A circular area of clear deck should be provided for winching operations and be:
- not less than 4.5 m in diameter;
- painted yellow with the surrounding deck painted a contrasting colour; and
- free of all obstacles (Fig. No.8).
(6) The clear deck area for winching operations should be located as close to the ship side as practicable.
(7) The clear deck for winching operations should have:
- at least two means of access located as far as practicable from one another, and
- a fire-retardant, non-skid surface.
Obstacle Limitations ^
(8) A circular limited-obstacle area for winching operations should be provided and:
- be not less than 30 m in diameter;
- need not be marked; and
- contain no obstacles higher than 3 m (Fig. No.8).
(9) Cargo derricks, crane booms, running rigging, radio antennae and similar movable obstacles in the helicopter approach, winching and departure areas should be loweredduring helicopter operations.
Grounding Facilities ^
(10) Grounding facilities should be provided between the helicopter and the ship’s deck for the removal and control of electrostatic accumulations; such facilities should be capable of automatic detachment without hazard to the helicopter.
Safety Notice ^
(11) The following notice should be prominently displayed in permanent lettering in areas adjacent to the winching-operations area:
During Helicopters Operations
No unauthorized persons allowed
Secure all loose objects
No naked lights - No smoking
Lighting ^
(12) A clear deck area for winching operations should be equipped with such floodlighting arrangements as do not interfere with the Pilot’s vision.
(13) Where needed for helicopter safety, red omnidirectional lights having average illumination intensity of between 20 and 25 candelas should be mounted on obstacles close to the limited-obstacle area.
Direction Indicator ^
(14) A wind-direction indicator showing wind conditions over the winching operations area should be fitted in accordance with subsection 7 (1).
Communication ^
(15) The winching-operations area should be fitted with telephone equipment suitable for communication with the bridge.
