IMO MSC 111: New Mass Code Adopted

The 111th session of the Maritime Safety Committee (MSC 111), held from 13 to 22 May 2026, concluded with the landmark adoption of the goal-based Code for Maritime Autonomous Surface Ships (MASS). This regulatory milestone addresses the rapid evolution of autonomous shipping technology, providing a structured framework for the safe operation of MASS vessels. As industry leaders like Kongsberg and Wärtsilä push boundaries, this new code ensures international standardization for automated navigation systems across global shipping lanes and major ports.

This new MASS Code represents a critical evolution of the International Convention for the Safety of Life at Sea (SOLAS), specifically impacting requirements under Chapter V regarding safety of navigation. By establishing goal-based standards, the IMO aims to integrate autonomous operations into existing safety management systems without compromising vessel integrity or environmental protection protocols under MARPOL. Compliance departments must now align their internal safety manuals and classification society requirements with these new international mandates to ensure that autonomous functions meet the rigorous safety benchmarks required for unrestricted global trade.

The adoption of the MASS Code will significantly alter the daily responsibilities of masters and navigating officers. These professionals must now transition toward remote monitoring and complex diagnostic oversight rather than traditional manual bridge control. Navigating officers are required to undergo specialized training in autonomous system management and cyber-security protocols. Mastery of these digital interfaces is now essential for maintaining vessel compliance and ensuring operational safety as the industry shifts toward higher levels of automation.
