heal.abstract	The fire safety and fire protection study on board ships is very important both at design stage and in during operation of the ship. In particular in recent years due to increased accidents, there is high demand for information, which can help prevent and forecast a fire, ultimately aiming to quickly extinguishing the fire or preferably avoiding the creation of a fire altogether. Through technological advancement in recent years, the study of fire propagation using simulation tools has been achieved. Simulation tools enables researches to simulate a fire in different condition, accurately. Such simulations in the marine sector have recently launched. This paper uses fire scenario simulations, to investigate how fire spreads in a RO-RO ship vehicle deck. Three different ways of starting a fire were studied: (a) starting a fire from a vent surface, (b) vent starting a fire from a vent surface at a specific rate of spread and (c) starting a fire from a combustion surface. In addition, different scenarios were studied regarding the arrangement of fuel and their location on the deck. The simulations in this dissertation were prepared via Pyrosim software, by ThunderHead Engineering Consultants, Inc. The example vehicle deck and vehicles on board were created in the software to enable the simulation of the fire. Using the thermal properties of the material make up of a typical vehicle, parameters were set. The first simulations were prepared with no ventilation systems, subsequent simulations were prepared using two ventilation systems. When preparing simulations for the entire deck, eleven ventilation systems were designed. In all case studies, the heat release rate curves (HRR) were prepared by the code established by the National Technical University of Athens, in the laboratory of Ship Design and Maritime Transport Department. The results were used to compare the validity of the observations of the simulation’s HRR curve. Then, by comparing the two curves, the importance of the way the fire started was observed as it determines the intensity and time of its development. The results of this dissertation reflect the reliability of the fire simulation tools method for the systematic study of fire phenomenon for simple as well as complex geometries.	el
