Modernized GMDSS: Impact on Radio Surveys in 2024

Modernized GMDSS: Impact on Radio Surveys in 2024

Introduction

On January1, 2024, the Global Maritime Distress and Safety System (GMDSS) underwentsignificant updates, affecting all SOLAS-compliant vessels. These changes aredesigned to incorporate advanced communication technologies, streamlineregulations, and enhance maritime safety.

Key Changes in GMDSS

‍

1. Expansion of Service Providers: The GMDSS now allows multiple   service providers beyond Inmarsat, including Iridium and possibly others.  This diversification is expected to improve the reliability and coverage  of maritime communication services.
2. Redefined Sea Areas: The definition of Sea Area A3 how varies based on the satellite service provider. For example, with Iridium's global coverage, Sea Area A3 includes previously separate areas  A3 and A4.
3. Unified Equipment Standards: All communication equipment requirements are now consolidated under SOLAS Chapter IV. This  consolidation includes the removal of the Narrow Band Direct Printing   (NBDP) function for MF/HF radio installations and mandates for updated  emergency beacons and satellite EPIRBs.
4. Updated Performance Standards: New performance standards for   GMDSS equipment have been introduced. These standards cover a range of  devices, from survival craft portable VHF radiotelephones to shipborne  integrated communication systems.
5. Mandatory Equipment Updates: Ships operating in Sea Area   A1 must replace VHF-EPIRB with satellite EPIRB. The use of Recognized  Mobile Satellite Service Ship Earth Stations (RMSS-SES) is now mandatory   for vessels in Sea Area A3.
6. Enhanced Communication Channels: VHF channels have been  modified to accommodate VHF Data Exchange System (VDES), improving  communication efficiency and ensuring compliance with the latest ITU  regulations.

Implications for Radio Surveys

Theseupdates necessitate comprehensive adjustments in radio surveys:

• Equipment Verification: Surveyors must verify the installation and functionality of the new GMDSS equipment, ensuring it  meets the updated standards.
• Certification Updates: Certificates must reflect the   new definitions and equipment requirements, especially for ships operating  in redefined sea areas.
• Training and Adaptation: Maritime professionals need  to stay informed about the new regulations and undergo training to  effectively handle the updated equipment and procedures.

Conclusion

Themodernization of the GMDSS represents a significant advancement in maritimesafety and communication. By embracing these changes, the maritime industry canimprove operational efficiency and ensure better safety standards. For maritimeprofessionals and stakeholders, staying updated with these changes and ensuringcompliance is crucial to navigating the evolving regulatory landscapeeffectively.
