ABSTRACT
The potential of ammonia as a sustainable marine fuel is accompanied by significant safety concerns. This study delves into the aftermath of ammonia tank leakage incidents, with a primary focus on evaluating the associated fire risks. Employing a general cargo ammonia-retrofit ship comprising of several high-pressure ammonia storage tanks, we conduct an in-depth analysis utilizing CFD modelling of the multifaceted factors that contribute to the severity of jet fire scenarios, encompassing different ammonia release rates, and leak directions (horizontal and vertical). The results show that in the event of fire, it poses significant safety concerns to the storage tanks, especially composite tanks, and therefore passive fire protection measure including the installation of the removable fire barrier is suggested as the design recommendation, apart from the active CO2 measures. The knowledge garnered from this research will empower stakeholders to refine their preparedness and response strategies in the event of fire accidents.
