The 11th session of the International Maritime Organization's Sub-Committee on Carriage of Cargoes and Containers (CCC 11) took place from September 8 to 12, 2025, marking a significant step forward in maritime safety and environmental sustainability. Among the key outcomes was the finalization of interim guidelines for utilizing hydrogen and ammonia as fuels, essential for promoting cleaner shipping practices. These guidelines aim to address safety concerns and ensure the efficient handling of these alternative fuels, particularly focusing on the implications for crew safety and cargo containment systems.

In addition to the fuel guidelines, CCC 11 developed a comprehensive working plan to tackle the pressing issue of container loss at sea, emphasizing the need for enhanced loading, stowage validation, and related inspection programs. This proactive approach seeks to mitigate risks associated with container shipping, which has become increasingly critical in light of recent maritime incidents.

The sub-committee also made strides in updating the International Code for the Construction and Equipment of Ships carrying Liquefied Gases (IGC Code), with draft amendments anticipated for approval in 2026. Furthermore, revisions to the interim recommendations for the carriage of liquefied hydrogen in bulk were completed, reinforcing the guidelines surrounding its safe transport.

Although time constraints limited discussions on certain guidelines, such as those regarding fuels with specific flashpoints, CCC 11 laid the groundwork for ongoing work through correspondence and intersessional groups. These groups will continue to refine frameworks for methyl ethyl alcohol and fuel cell power installations, with timelines for future approvals set for 2027 and 2028, respectively.

The session also addressed the need for improved fumigation practices in cargo holds, recognizing the importance of continuous gas detection and enhanced risk controls. As the industry evolves, the committee highlighted the necessity of adapting existing codes to meet new challenges, including the safe transport of contaminated soil and the classification of various cargo types.

With a clear focus on safety and sustainability, CCC 11's resolutions and recommendations pave the way for more stringent regulations and practices, establishing a robust framework for the future of maritime transport in an increasingly eco-conscious world.
