In Norway, classification society DNV released a new white paper titled Safe introduction of alternative fuels, detailing a seven-step, structured process for shipowners worldwide to gain approval for ammonia- and hydrogen-fueled vessels under the IMO’s alternative design approval process, citing the lack of existing IMO regulation and emphasizing early engagement with flag states and DNV’s own rule frameworks as essential to reducing complexity.
“We outline seven steps to assist shipowners and other stakeholders in obtaining approval and safely deploying ammonia- and hydrogen-fuelled ships in today’s immature regulatory environment,” said Linda Hammer, Principal Consultant at DNV and lead author of the report. The guide addresses risks tied to each fuel: hydrogen’s flammability and cryogenic storage, and ammonia’s toxicity and corrosiveness. It also recommends changes in ship operations, training, and safety systems.
The ADA process, as outlined in MSC.1/Circ.1455, remains the only path forward until IMO updates its IGF Code. DNV’s 2021 and 2024 class notations provide prescriptive requirements to streamline approval. “Organizations must also adapt their safety management systems to ensure continuous oversight of fuel system integrity and safety,” Hammer said. The white paper is available for free download via DNV.
