The International Maritime Organization (IMO) has adopted the first global code for maritime autonomous surface ships.
The International Code of Safety for Maritime Autonomous Surface Ships, known as the MASS Code, was adopted during the 111th session of the Maritime Safety Committee in London.
The new framework is intended to support the safe integration of autonomous and remotely operated commercial vessels into international shipping.
According to the IMO, the Code sets out a goal-based framework designed to ensure that autonomous ships are built, operated and certified to safety and environmental standards equivalent to those applied to conventional vessels.

The MASS Code will apply to large internationally trading cargo ships and is due to take effect from 1 July 2026.
It will initially be voluntary for at least two years, allowing Member States to test its application before potential mandatory implementation under the SOLAS Convention.
A Maritime Autonomous Surface Ship is defined as a vessel capable of operating with varying levels of independence from human interaction.
This can include ships using automation with crew on board, remotely controlled vessels with or without crew, and fully autonomous ships able to make decisions independently.
The Maritime Safety Committee meeting is taking place from 13 to 22 May.
