1 The Maritime Safety Committee, at its 102nd session (4 to 11 November
2020), acknowledging a potential need for alternative metallic materials to be used
for the construction and safe operation of low-temperature fuel and cargo-carrying
ships and the need for guidance in this respect, approved the Guidelines for the
acceptance of alternative metallic materials for cryogenic service in ships
carrying liquefied gases in bulk and ships using gases or other low-flashpoint
fuels, as set out in the annex, prepared by the Sub-Committee on Carriage of
Cargoes and Containers (CCC), at its sixth session (9 to 13 September 2019).
2 The Guidelines provide detailed guidance on how to document alternative
metallic materials for their suitability and compliance with the IGC
and IGF Codes, and a framework for evaluation and approval of alternative
metallic materials for cryogenic service.
3 Member States are invited to bring the annexed Guidelines to the
attention of all parties concerned.
