Two ammonia-ready vessels - the CMA CGM Masai Mara and the ALS Ceres - were delivered this May. Both are the first in a series of six containerships contracted to be built at different Chinese shipyards.
A new MoU between WinGD and Mitsubishi Shipbuilding will see the deployment of WinGD’s X-DF-A ammonia-fueled engines to a range of vessels. In Norway, Wärtsilä has unveiled a safety system designed for continuous onboard monitoring of ammonia leaks, featuring a staged combustion process to deal with accidental releases. And classification society DNV has awarded AiP to two significant ammonia-fueled vessel designs: the MS NoGAPs, and Viridis Bulk Carriers’ short sea bulk carrier.
ABS has used computational fluid dynamics to model ammonia dispersion patterns in a ship’s engine room, with the aim of producing a fast, real-time response system for ammonia leaks. In Japan, a fuel supply system for large-scale, low-speed, two-stroke marine engines is undergoing final verification testing. Mitsubishi Shipbuilding aims to become a key technology provider of such systems, and in the ammonia maritime fuel space.
As part of our Maritime Ammonia Insights webinar series, we explored the safety learnings gained so far during the development of maritime ammonia fueled engines, as well as existing best practices for safe ammonia handling. John Mott (ASTI), Kaj Portin and Laura Sariola (both Wärtsilä) were joined in conversation by Conor Furstenberg Stott.
Successful testing has been completed at IHI’s facilities in Ota, Japan. A four-stroke marine engine - fully integrated with exhaust gas aftertreatment and fuel supply systems - produced stable operations running on up to 80% ammonia fuel. Emissions of dinitrogen monoxide (N2O) and ammonia slip were reported as “virtually zero”.
The CAMPFIRE consortium is exploring the feasibility of ammonia-powered cruise liners on the Baltic Sea. Project partners Rostock Port, Yara, DNV and Carnival Maritime discussed progress to date at a recent Maritime Ammonia Insights webinar, including promising logistics, infrastructure & safety findings.
Explore the critical topic of engine room safety, and what design considerations would be needed on a future, ammonia-fueled vessel. What learnings can we apply from running prototype engines? What lessons can be learned from current ammonia-handling industries like refrigeration? And what training will be needed to build confidence in seafarers?
In maritime ammonia updates this week:
A high-profile consortium will conduct a joint study exploring ammonia bunkering at the Port of Savannah in Georgia, USA. The consortium aims to establish a comprehensive supply chain to allow ship-to-ship ammonia bunkering in Savannah, and the study scope includes design of an Ammonia Bunkering Articulated Tug-Barge (AB-ATB) vessel.
We explore the GreenBalticCruising project, investigating the potential of a cruise ship route across the Baltic Sea, powered by ammonia fuel.
