IMO Sub-Committee Finalizes Revised Methanol Fuel Guidelines | Mariner News

The International Maritime Organization’s (IMO) Sub-Committee on Carriage of Cargoes and Containers (CCC) has finalized revised interim guidelines for ships using methanol and other methyl/ethyl alcohol fuels. This development provides a more robust and experience-driven framework for the design and operation of methanol-powered vessels.

Concluded during the CCC 12th session, held from September 14-18, the updated framework incorporates operational experience gained from vessels already utilizing these alternative fuels. Key changes include greater flexibility in fuel tank placement and leakage-handling arrangements, alongside a new approach to the ventilation of fuel spaces. This enhanced flexibility can optimize ship design, potentially reducing the impact on cargo capacity and improving overall vessel economics for newbuilds.

Further revisions expand provisions for bunkering station design and fire-extinguishing arrangements. The guidelines also introduce explicit guidance on bunkering operations and personal protective equipment. These additions signify a maturation of safety protocols specific to methanol, moving towards standardized best practices and fostering greater confidence within the industry regarding the safe handling and bunkering of methanol.

Finalization by the Sub-Committee provides a clearer, more predictable regulatory pathway, which is crucial for shipowners and investors considering long-term commitments to methanol-fuelled newbuilds or conversions. These revised guidelines now await further consideration and approval by the IMO’s Maritime Safety Committee.
