GUIDELINES FOR THE PARTICIPATION OF NON-CONVENTION SHIPS IN THE GLOBAL MARITIME DISTRESS AND SAFETY SYSTEM (GMDSS)
|
| � |
|
1. At its fifty-fourth session, the Maritime Safety Committee approved draft guidelines for non-Convention ships in the GMDSS (MSC 54/23, paragraph 5.1.8 and COM 32/12, annex 4) for circulation to Member Governments.
2. At the request of the Committee the above Guidelines, attached hereto, are brought to the attention of Member Governments.

Annex
GUIDELINES FOR THE PARTICIPATION OF NON-CONVENTION SHIPS IN THE GMDSS
|

1. These guidelines are intended to assist Administrations which may wish to develop national measures aiming at providing a link between the GMDSS and ships, hereinafter referred to as "non-Convention ships", to which chapter IV of SOLAS does not apply.
2. It should be noted that until the full implementation of the GMDSS*, coast stations and Convention ships should: - maintain a continuous watch on the radiotelephone distress frequencies 2,182 kHz and 156.8 MHz; - transmit the radiotelephone alarm signal on 2,182 kHz.
3. The following functional requirements of the GMDSS are considered as appropriate to allow effective participation of non-Convention ships in the GMDSS with respect to distress and safety communications:
1. to provide safety for own ship
1.1. performing ship-to-shore distress alerting;
1.2. transmitting ship-to-ship distress alerting;
1.3. transmitting and receiving on-scene communications including appropriate SAR co-ordinating communications;
1.4. transmitting locating signals
2. to assist other ships in distress:
2.1. receiving shore-to-ship distress alerting; and
2.2. receiving ship-to-shore distress alerting
4. If a non-Convention ship carries voluntarily, for its own particular reasons, DSC equipment with a radiotelephone capability operating on GMDSS frequencies or an INMARSAT ship earth station (SES), such equipment can be utilised to perform most of the functions described above.
5. It is recommended that non-Convention ships operating in high sea areas should carry a satellite EPIRB which could be manually activated.
6. To avoid unauthorised use of dedicated distress frequencies it is further recommended that non-Convention ships should carry equipment for general radiotelephone communications operating in radio systems appropriate to their areas of operation.
7. In performing the functional requirement of transmitting locating signals note should be taken that the 9 GHz SAR radar transponder will be the main means to fulfil this requirement in the GMDSS.
8. Provision should be made for the reception of navigational and meteorological warnings and urgent safety information, depending on the area of operation and the services available in that area, e.g. NAVTEX, radiotelephony, satellite broadcasts, etc. |
