Engine room fire safety evaluation of ammonia as marine fuel

Ammonia fuelled vessels are not a distant reality anymore. This paper will examine whether ammonia constitutes greater fire hazard than conventional fuel types in the event of an engine room fire. It is to showcase how realistic outbreak can be modelled for case vessel 50,000 dead weight tonnage bulk carrier. Four simulation scenarios then modelled, and their outputs analysed discussed. From simulations process, it was evident that does present danger diesel or natural gas Ammonia’s behaviour better fires with relation soot formation potential machinery damage. An provides evacuation window; has more even temperature distribution through space developed flame temperatures were lower. The main conclusion this project due flammability limits thermal properties, dispersion would take time thus reduce likelihood occurring manageable.
