CCSTechnical Information(2014)Technical Information No.23 Total No.145Aug.08,2014(Total2+5pages)To:ship owners/managers/operators.Notice on the guidance for the validity ofradiocommunication equipmentinstalled and used on ships (MSC.1/Circ.1460)The World Radiocommunication Conference 2012 made extensive changes to appendices 17 and18 of the Radio Regulations(RR).Whilst these changes do not affect the GMDSS,they do affectthe use of other frequencies that would be used by services such as Port Operations and VTS.Considering that incompatibility may exist between radiocommunication equipment installed onships,and the revised frequencies and channelling arrangements for the maritime HF and VHFbands as contained in appendices 17 and 18 to the Radio Regulations(RR)-Edition 2012,TheMaritime Safety Committee,at its ninety-second session (12 to 21 June 2013),approved theGuidance on the validity of radiocommunications equipment installed and used on ships.According to this guidance,action should be taken as follows:1.Timely action is required by ships to ensure that radiocommunication equipment complies withthe RR.Replacement of operating hardware may be necessary to meet the changed requirements.2.To ensure GMDSS communication capability,HF radiocommunication equipment capable ofoperating narrow-band direct printing (NBDP)should be updated so that following the first radiosurvey after 1 January 2017 it meets the channelling arrangements reflected in sections II and IIIof part B in appendix 17 of the Radio Regulations.3.Radiocommunication equipment,other than HF radiocommunication equipment capable ofoperating NBDP,does not necessarily need to be updated by the first radio survey after 1 January2017,but may be updated appropriately in accordance with the decisions of the Administration.Hereby notify the above.This Technical Information is published on CCS website(www.ccs.org.cn)and is to be forwardedby CCS branches to relevant shipyards,product manufacturers and shipping companies inrelevance to their business area.
