The International Maritime Organization (IMO) Sub-Committee on Cargo Transport and Containers finalized its review of interim guidelines for the use of methyl and ethyl alcohols as ship fuel during its twelfth session held from September 14 to 18, 2026. These revisions aim to enhance safety and efficiency on ships and facilitate the use of these types of fuels.
Revisions to Safety Guidelines
The finalized guidelines allow ships greater flexibility in selecting fuel tank locations and measures related to leaks. Revisions include the introduction of a new concept for ventilating fuel spaces and expanding design guidelines for refueling stations and fire suppression systems. Additionally, new guidelines regarding refueling operations and personal protective equipment have also been added.

Guidelines for Low Flashpoint Oil Fuels
Continuing its work, the CCC 12 committee examined interim guidelines for ships using low flashpoint oil fuels (between 52 to 60 degrees Celsius). The agreement reached prevented the development of specific provisions for the "temperature-controlled engine room concept" and focused on a safety concept that is more compatible with existing guidelines in the IGF Code. Work on these guidelines will continue and is expected to be finalized at the CCC 13 meeting in 2027.
The committee also reviewed amendments to the IGF Code and developed guidelines for alternative fuels and related technologies. In this context, recommendations for improving the safety of fuel cell power installations were also proposed.
Development of Safety Frameworks to Reduce Greenhouse Gas Emissions
Committee 12 also discussed the development of guidelines for the safety of ships equipped with carbon capture and storage systems (OCCS). These guidelines should include a technology-neutral main body for common ship requirements, while specific technology safety requirements will be placed in separate annexes. Work on these guidelines will continue and is expected to be finalized in 2028.
Development of a Database for Solid Cargoes
The CCC 12 committee also worked on developing a database for solid cargoes that are not listed in the IMSBC Code. This database will be created to provide more accurate information about various cargoes. In this regard, a call for data submissions from authorities for inclusion in the database was also made.
Finally, proposed amendments to the IMDG Code and its annexes were discussed, and suggestions for improving the safety of hazardous cargoes were also presented. These amendments are expected to be approved in 2028.
