Abstract
Introducing ammonia as a ship-fuel comes with different challenges. This paper analyzes some of the safety aspects
of using ammonia as a fuel for vessel propulsion. Specifically, the study focuses on the handling of accidental
releases from the refrigerated storage tank and the connected fuel systems within enclosed spaces, such as the tank
room and the engine room. A possible handing technology for ammonia leaks on ships are compact ammonia
scrubbers, and to enable such compact scrubbers this work also studies the influence of packed bed geometries on
bubble dynamics, identifying design characteristics that can improve ammonia dissolution or neutralization
efficiency
