IMO approves autonomous shipping code

The new framework is designed to support the safe integration of autonomous and remotely operated commercial vessels into global shipping operations. Developed as a goal-based regulatory framework, the MASS Code establishes requirements intended to ensure autonomous ships meet safety and environmental standards equivalent to those applied to conventionally operated vessels.

The code applies to large cargo ships engaged in international trade and is scheduled to enter into effect on 1 July 2026. Initially, it will operate on a voluntary basis for a minimum of two years, allowing member states to assess implementation and operational performance before potential mandatory adoption under the SOLAS Convention.

The framework covers vessels operating with varying degrees of autonomy, ranging from ships using automated systems with crews onboard to remotely controlled vessels and fully autonomous ships capable of independent decision-making.

The adoption of the MASS Code represents a significant regulatory milestone for the maritime industry as shipping companies, technology developers and flag administrations continue investing in digitalisation and autonomous vessel technologies.

The Maritime Safety Committee session, held at IMO headquarters in London, runs from 13 to 22 May and addresses a broad range of international shipping safety and regulatory matters.
