Classification society DNV on Monday (21 September) highlighted progress made on several regulatory and technical matters at the 12th session of the IMO Sub-Committee on Carriage of Cargoes and Containers (CCC 12), held from 14 to 18 September. This includes alternative fuels, cargo securing, onboard carbon capture systems, and battery carriage: Amendments to the IGF Code and development of guidelines for alternative fuels and related technologies Methyl/ethyl alcohols CCC 12 finalized the revision of the Interim Guidelines for the Safety of Ships Using Methyl/Ethyl Alcohol as Fuel (MSC.1/Circ.1621). The amendments revise all sections of the existing guidelines, taking into account experience gained to date. The revised guidelines: provide more flexibility in fuel tank placement and leakage-handling arrangements; introduce a new concept for ventilation of fuel spaces; expand guidance on the design of bunkering stations and fire extinguishing; and add new guidance on bunkering operations and personal protective equipment. Low-flashpoint oil fuels CCC 12 continued work on the interim guidelines for ships using low-flashpoint oil fuels (fuel with a flashpoint between 52°C and 60°C). It was agreed not to develop detailed provisions for the “temperature-controlled engine room concept” but focus on a safety concept more aligned with the existing guidelines under the IGF code, however with major simplifications of the safety barriers. Work on the interim guidelines will continue in a Correspondence Group aiming for finalization at CCC 13 in 2027. Fuel cell power installations and IGF Code amendments The revision of the Interim Guidelines for the Safety of Ships Using Fuel Cell Power Installations (MSC.1/Circ.1647), and other proposals for amendments to the IGF Code were not discussed in detail, but work will continue in a Correspondence Group reporting to CCC 13 in 2027. Development of a safety regulatory framework to support the reduction of GHG emissions from ships using
