IMO MSC 111: New MASS Code adopted

The 111th session of the Maritime Safety Committee (MSC 111) was held from 13 to 22 May 2026. The adoption of a new goal-based Code for Maritime Autonomous Surface Ships (MASS) marks a key milestone in the IMO’s work to ensure the regulatory framework keeps pace with the rapid development of shipping technologies. MSC 111 also approved revised explanatory notes for the Safe Return to Port concept for passenger ships, as well as draft amendments to the IGC Code for gas carriers to incorporate a decade of Unified Interpretations, turning operational experience into clearer and more consistent requirements.
