Offshore Fixed Installations will be assigned appropriate Aeronautical VHF and Non-Directional Radio Beacon (NDB) Frequency Assignments by the CAA which may take between 4 and 6 weeks to obtain depending on the international co-ordination necessary.
Offshore Mobile Installations and Vessels are required to use different VHF and NDB frequencies depending on their location.
