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.
