The shipping industry is transitioning to carbon-neutral fuels, with ammonia and hydrogen emerging as potential options. DNV's latest white paper addresses the lack of mandatory regulations for these fuels, offering guidance to shipowners on implementing them safely. Both hydrogen and ammonia bring new safety risks, highlighting the importance of safety in ship operations. DNV supports the industry's adoption of these fuels through initiatives like the Nordic Roadmap for Future Fuels and prescriptive classification rules. The white paper emphasizes the need for careful planning, technical expertise, crew upskilling, and industry collaboration to scale up these zero-carbon fuels effectively. To ensure safe operations, ships using these fuels must update safety management systems, provide detailed operating procedures, offer comprehensive training, and foster a robust safety culture. DNV has developed classification rules for ammonia-fuelled ships in 2021 and hydrogen-fuelled ships in July 2024, aiming to provide predictability for stakeholders in the industry. The focus is on enhancing safety and supporting the decarbonization journey in the maritime sector.
