Autonomous Shipping (MASS)

IMO adopted a new International Code of Safety for Maritime Autonomous Surface Ships (MASS Code) in May 2026, marking a major regulatory milestone for autonomous shipping. The Code will take effect from 1 July 2026.

 

Technological innovation within the maritime industry is resulting in rapid developments that will see the commercial use of autonomous ships, whether they are controlled remotely or are fully autonomous. Such change requires robust regulation to ensure the safety of life at sea, as well as of cargo on board and of the vessel itself.

IMO aims to integrate new and advancing technologies in its regulatory framework - balancing the benefits derived from new and advancing technologies against safety and security concerns, the impact on the environment and on international trade facilitation, the potential costs to the industry, and their impact on personnel, both on board and ashore. IMO wants to ensure that the regulatory framework for Maritime Autonomous Surface Ships (MASS) keeps pace with technological developments that are rapidly evolving.
