Helideck Prohibited Landing Marker
Manufactured from:
PE610 Red/Yellow Matt PVC coated Nylon fabric.
12mm Die Brass grommet Eyelets 1mt apart all round.
1 x 8mm Die white staple spun x 30mt Polypropylene rope tie cord for attachment to the landing net.
Packed weight, 15kg packed size 600mm x 400mm x 300mm

For certain operational or technical reasons an installation may have to prohibit helicopter operations. In such circumstances, where the helideck cannot be used, the ‘closed’ state of the helideck should be indicated by use of the international standard “landing prohibited” signal, yellow cross on red background, given in the Rules of the Air and Air Traffic Control Regulations, except that it has been altered in size to just cover the letter ‘H’ inside the aiming circle.
Dimensions: 4m X 4m Red with diagonal 50cm wide yellow cross.
Perorating Operations: Helideck/Heliport Operational Hazard Warning(s)/Procedure(s)
Perorating Operations
Explosive charges used in conjunction with perforation operations offshore can potentially be prematurely detonated by radio transmissions, including those from helicopters. The following practice is recommended:
Personnel Conducting Perforating Operations: Whenever perforating operations are scheduled and operators are concerned that radio transmissions from helicopters in the vicinity may jeopardize the operation, personnel conducting operations should take the following precautionary measures:
1. Notify company aviation departments, helicopter operators or bases, and nearby manned platforms of the pending perforation operation so the Notice to Airmen (NOTAM) system can be activated for the perforation operation and the temporary helideck closure.
2. Additional considerations:
To close the decks install a temporary marker as shown in the figure below, or in accordance with RP 2008-1;
(Note) The marker should be installed during the time that charges may be affected by radio transmissions.
Pilots
1. Pilots when operating within 1,640 feet (500m) of a known perforation operation will avoid radio transmissions from or near the helideck (within 1,640 feet) and will not land on the deck if the X is present. Radio transmissions Include signals emitted from aircraft radar and transponders which should be completed via alternate communication means available on the rig or platform.
2. Whenever possible, make radio calls to the platform being approached or to the Flight Following Communications Center at least one mile out on approach. Ensure all communications are complete outside the 1640 foot hazard distance. If no response is received, or if the platform is not radio equipped, further radio transmissions should not be made until visual contact with the deck indicates it is open for operation
