Commercial readiness confirmed for Alfa Laval's ammonia fuel supply system as FAT wraps up
Swedish marine technology company Alfa Laval has completed the certified factory acceptance test (FAT) for the FCM Ammonia fuel supply system, class certified by China Classification Society (CCS), confirming commercial readiness for ammonia-fueled engines.

The FAT validates the design, control architecture, safety layers and ammonia-handling routines in a marine environment, with the test program covering full hardware integration and I/O verification, control and safety logic validation, simulation of operational and fault scenarios, functional testing of ammonia-handling, and detailed documentation review conducted in accordance with class requirements.
According to Alfa Laval, it confirms that the fuel supply system has passed all functional and safety verification procedures in accordance with required standards, demonstrating that it is engineered and tested for safe integration into an ammonia-fuelled two-stroke engine environment.
The FAT has been completed for the first FCM Ammonia out of seven units ordered by Chinese shipowner Tianjin Southwest Maritime (TSM) for its dual-fuel ammonia carriers.
“By completing the certified FAT for Alfa Laval’s FCM Ammonia, one of the first in the industry for a two-stroke dual-fuel ammonia application, we position
