Various flag Administrations has issued a Marine Safety Advisory to inform about the IMO requirements which ensure  Global Maritime Distress and Safety System (GMDSS) communication capability. The high frequency (HF) radiocommunications equipment capable of operating narrow-band direct printing (NBDP) is updated to meet the new channeling arrangements, contained n the 2012 Radio Regulations HF, Appendix 17, Part B, Sections II and III (HF direct-printing telegraphy), by the first safety radio survey after 01 January 2017.  Source: www.safety4sea.com


While most existing equipment should already be in compliance with these requirements, equipment that is unable to comply with the Radio Regulations will need to be replaced, and the newly installed HF NBDP equipment should be suitably type approved per guidance issued in IMO Circular MSC.1/Circ.1460 Guidance on the Validity of Radiocommunications Equipment Installed and Used On Ships.

 

Owners and Masters of vessels equipped with HF NBDP equipment should therefore ensure it is HF direct-printing telegraphy compliant in time for the first safety radio survey after 01 January 2017.

 

To ensure GMDSS communication capability, HF radiocommunication equipment capable of operating narrow-band direct printing (NBDP) should be updated so that following the first radio survey after 1 January 2017 it meets the channelling arrangements reflected in sections II and III of part B in appendix 17 of the RR.

 

Radiocommunication equipment , other than HF radiocommunication equipment capable of operating NBDP, does not necessarily need to be updated by the first radio survey after 1 January 2017, but may be updated appropriately in accordance with the decisions of the Administration
