SOLAS 2024: modernization of requirements for lifesaving appliances and radio communication has come into force

On January 1, 2024, a set of amendments to the International Convention for the Safety of Life at Sea (SOLAS) came into force, significantly modernizing the requirements for ship safety equipment and systems.

Key changes in GMDSS

The most significant changes concern the Global Maritime Distress and Safety System (GMDSS). The requirements have been revised to become more universal and independent of specific service providers. Outdated systems have been excluded, and the requirements for communication equipment have been moved from Chapter III of SOLAS on lifesaving appliances to Chapter IV on radio communications.

Changes in the definition of maritime areas

The definitions of maritime areas A1-A4 have been updated. Now the geographical coverage area may vary among different satellite service providers. Historically, since 1988, INMARSAT has been the only approved satellite communication provider for GMDSS. In 2018, the IMO also recognized Iridium, and the 2020 SOLAS update introduced the new term “recognized mobile satellite service.”

Requirements for ships

New design requirements apply to cargo and passenger ships with a gross tonnage of more than 3000 GT, built on or after January 1, 2024, as well as to ships with a gross tonnage of 3000 GT and below, as far as practicable. The amendments also apply to new ships using natural gas as fuel.

Outlook for 2026

The IMO, recognizing delays caused by the COVID-19 situation, has introduced a special medium-term amendment cycle. The next SOLAS update will come into force on January 1, 2026, and will include amendments adopted by July 1, 2024.
