This edition of the Manual, renamed the International SafetyNET Services Manual, incorporates changes introduced to the Inmarsat satellite network and services including the Inmarsat Fleet Safety service, which has been recognized as a mobile satellite service for use in the GMDSS by adoption of resolution MSC.450(99).

Foreword

SOLAS regulation IV/12.2 states that "Every ship, while at sea, shall maintain a radio watch for broadcasts of maritime safety information on the appropriate frequency or frequencies on which such information is broadcast for the area in which the ship is navigating."

At the request of the International Maritime Organization (IMO) Sub-Committee on Radiocommunications, the International SafetyNET Manual was first produced in 1994. The second edition was published in 2003 containing amendments approved at MSC 76 in December 2002, by MSC/Circ.1064.

At its seventh meeting in September 2005, the International Hydrographic Organization (IHO) Commission on the Promulgation of Radio Navigational Warnings (CPRNW)* established a Working Group to review all World- Wide Navigational Warning Service (WWNWS) documentation. The Working Group included representation from the World Meteorological Organization (WMO) and prepared revisions to resolutions A.705(17) on Promulgation of Maritime Safety Information and A.706(17) on World-Wide Navigational Warning Service. The proposed revisions of the resolutions were circulated to IHO Member States under IHB CL 104/2007, endorsed by the Sub-Committee on Communication and Search and Rescue (COMSAR), at its twelfth session in April 2008, and subsequently approved by MSC 85 in November/December 2008 by MSC.1/Circ.1287 and MSC.1/Circ.1288, respectively.

The IHO CPRNW Working Group then prepared the revised Joint IMO/IHO/WMO Manual on Maritime Safety Information incorporating the revised information from resolutions A.705(17), as amended, and A.706(17), as amended. The revised text of the Joint IMO/IHO/WMO Manual on Maritime Safety Information was circulated to IHO Member States under cover of IHB CL 70/2008, endorsed by COMSAR 13 in January 2009 and subsequently approved by MSC 86 in May/June 2009 by MSC.1/Circ.1310.

Continuing with the holistic approach of reviewing all maritime safety information documents from the top down, the IHO WWNWS-SC Working Group prepared the third revision of the International SafetyNET Manual. The revised text of the International SafetyNET Manual was circulated to IHO Member States under cover of IHB CL 68/2009, endorsed by COMSAR 14 in March 2010 and subsequently approved by MSC 87 in May 2010 by MSC.1/Circ.1364, which became effective on 1 January 2012.

As part of its editorial review of all maritime safety information documentation, the IHO WWNWS-SC continued to review the text of the International SafetyNET Manual. The review took into account the amendments adopted to resolutions A.705(17) and A.706(17) and the approval of MSC.1/Circ.1310/Rev.1 on Joint IMO/IHO/WMO Manual on Maritime Safety Information. These changes were published as MSC.1/Circ.1287/Rev.1 and MSC.1/Circ.1288/Rev.1, which became effective on 1 January 2015, and MSC.1/Circ.1310/Rev.1, which became effective on 1 January 2016.

The fourth revision of the International SafetyNET Manual took place following the first session of the Sub-Committee on Navigation, Communications and Search and Rescue (NCSR) in June/July 2014 and WWNWS6 in August 2014. Subsequently, it was submitted to WMO for approval prior to submission to NCSR 3 for endorsement and final approval by MSC 97 and publication as MSC.1/Circ.1364/Rev.1, with an effective date of 1 January 2018. MSC.1/Circ.1364/Rev.1, amended by MSC.1/Circ.1364/Rev.1/Corr.1, became effective on 1 January 2020.
