ClassNK’s new Guidelines for Safety Operation for Ammonia-Fueled Vessels cover aspects for the daily operation of ammonia-fueled vessels, including accident response measures, PPE requirements, how to define hazardous areas, and bunker transfer processes.
Fuel/Energy Type: Ammonia
Emission performance of ammonia-fueled, two-stroke marine engines
In the lead up to its historic 83rd meeting this April, the IMO’s MEPC (Marine Environment Protection Committee) published a “Review of current literature on tank-to-wake nitrous oxide emissions from ammonia-fueled engines“.
DNV white paper guides shipowners on safe and scalable adoption of ammonia and hydrogen fuels
As the shipping industry continues its transition to carbon-neutral fuels, ammonia and hydrogen are emerging as possible fuel options, however mandatory regulations governing their use are not yet in place. DNV’s latest white paper, Safe introduction of alternative fuels – Focus on ammonia and hydrogen as ship fuels, provides shipowners with insights and tools to navigate the evolving regulatory landscape and safely implement these fuels.
Seafarer training for marine ammonia fuel comes into focus
Already in 2025, we have seen multiple initiatives launched and resources released to contribute to seafarer training ahead of the first ammonia-fueled vessels.
World’s first ammonia-fueled ship hits a snag
The promise of zero-carbon shipping has been delayed until at least 2026.
Ammonia-powered vessel docks in Southampton
The “world’s first” dual-fuelled ammonia-powered vessel has arrived in the UK, docking at the Port of Southampton.
Ammonia as fuel – competencies and training
With the need to reduce carbon emissions, vessel owners and operators are looking to the use of alternative fuels to aid with their emissions reduction efforts.
Successful ship-to-ship ammonia transfers pave the way for ammonia bunkering in the Pilbara region
A Global Centre for Maritime Decarbonisation-led consortium has successfully conducted ship-to-ship transfers of ammonia at anchorages within the Port of Dampier on 14 September 2024.
Tugboat powered by ammonia sails for the first time, showing how to cut emissions from shipping
On a tributary of the Hudson River, a tugboat powered by ammonia eased away from the shipyard dock and sailed for the first time to show how the maritime industry can slash planet-warming carbon dioxide emissions.
Ammonia toxicity concerns in focus for shipping as Singapore cleans up oil spill
Ammonia toxicity concerns are in focus after an oil spill incident in June at Singapore’s Pasir Panjang Terminal, as the shipping industry doubles down on cleaner fuels for maritime decarbonation with keen interest in risk management and preparedness to deal with future bunker spills.
