705(17) Promulgation of maritime safety information

Annex Recommendation on promulgation of maritime safety information

1 Introduction

1 - Introduction

1.1 The maritime safety information service is an internationally co-ordinates network of radio broadcasts containing information which is necessary for safe navigation, received in all ships by equipment which automatically* monitors the appropriate frequencies and prints out in simple English only that information which is relevant to the ship. This concept is illustrated in figure 1.

1.2 Maritime safety information (MSI) is of vital concern to all vessels. It is therefore essential that common standards are applied to the collection, editing and dissemination of this information. Only by doing so will the mariner be assured of receiving the information he needs, in a form which he understands, at the earliest possible time.

1.3 The purpose of this Recommendation is to set out the organization, standards and methods which should be used for the promulgation and reception of maritime safety information.

---

*The Organization gas decided that manual operation will be acceptable for receiving broadcasts of MSI via the operational HF NBDP system (where available) until the full implementation of the GMDSS on 1

6 Co-ordination procedures

6.1 In order to make the best use of automated reception facilities and to ensure that the mariner receives the minimum information necessary for safe navigation, careful co-ordination is required.

6.2 In general, this requirement for co-operation and co-ordination will be met by the standard operational procedures of IHO, WMO, International Telecommunication Union (ITU) and INMARSAT.

6.3 Cases of difficulty should be referred, in the first instance, to the most appropriate parent body.

6.4 Member States wishing to provide maritime safety information services should nominate a national co-ordinator for each type of information concerned, informing the Organization of such nominations as they are made. The Organization will maintain and, through the Maritime Safety Committee, publish a list of the nominated co-ordinators.

6.5 The establishment of transmissions in the international NAVTEX service is co-ordinated by the Maritime Safety Committee. Detailed guidance on the provision of NAVTEX services is contained in the NAVTEX Manual.

6.6 The use of satellite maritime safety information services is co-ordinated by the Maritime Safety Committee.

6.7 The designation of service areas is an important part of the co-ordination process since it is intended that a vessel should be able to obtain all the information relevant to a given area from a single source. Information co-ordinators should, therefore, design their broadcasts to suit a particular service area. The Maritime Safety Committee will designate service areas for the international SafetyNET service and the international NAVTEX service. In doing so, the Committee will take full account of the character and volume of information and the pattern of maritime traffic in the region and the advice of IHO and WMO.

6 Co-ordination procedures

6 Coordination procedures

6.1 In order to make the best use of automated reception facilities, and to ensure that the mariner receives only that information necessary for safe navigation, careful coordination is required.

6.2 In general, this requirement for coordination will be met by the standard operational procedures of the Organization, International Hydrographic Organization (IHO), World Meteorological Organization (WMO), International Telecommunication Union (ITU) and the International Mobile Satellite Organization (IMSO). Cases of difficulty should be referred, in the first instance, to the most appropriate parent body.

6.3 Administrations broadcasting maritime safety information should provide details of services to the Organization, which will maintain and publish this as part of the GMDSS Master Plan.

6.4 The coordination of changes to operational NAVTEX services and of the establishment of new stations is undertaken by the Coordinating Panel on NAVTEX Services of the Sub-Committee on Radiocommunications and Search and Rescue on behalf of the Maritime Safety Committee.

6.5 The coordination of changes to operational SafetyNET services and of the authorization and registration of information providers is undertaken by the International SafetyNET Coordinating Panel of the Sub-Committee on Radiocommunications and Search and Rescue on behalf of the Maritime Safety Committee.

6.6 Administrations should design their broadcasts to suit specific service areas. The designation of service areas is an important part of the coordination process since it is intended that a ship should be able to obtain all the information relevant to a given area from a single source. The Maritime Safety Committee approves NAVAREAs/METAREAs and service areas for the International NAVTEX and SafetyNET service as advised by IHO and WMO.
