heal.abstract	Στην παρούσα μεταπτυχιακή εργασία μπορεί ο αναγνώστης να πληροφορηθεί για θέματα που αφορούν την μηχανολογία της πυρκαγιάς, ενώ παράλληλα γίνεται μια σύγκριση των όσων προβλέπονται στο κεφάλαιο ΙΙ-2 της SOLAS περί πυρασφάλειας στα εμπορικά πλοία και των όσων ισχύουν περί καταπολέμησης της πυρκαγιάς σε ένα πολεμικό πλοίο. Τέλος, γίνεται μια προσομοίωση σε περιβάλλον FDS όπου εξετάζεται η επιβιώσιμοτητα ενός αγήματος καταπολέμησης της πυρκαγιάς στα παράγωγα της (καπνός, τοξικές ουσίες, θερμοκρασία).	el
heal.abstract	The main purpose of the present diploma thesis is the application of the probabilistic model of safety evaluation against fire (as it is described in the work of Spyrou and Themelis (2012)) on a warship, and more specifically, a frigate. Part I consists of 3 chapters.In chapter 1, general information is presented regarding the thesis, such as its structure and objectives. Also, there is a brief presentation of several theses of a similar subject. In chapter 2, the theoretical background of fire engineering is presented. Useful information regarding the main fire substances, their effects on the human body, the ways to engage them and several phenomena that relate to fire itself (like rollover and backdraft) is presented. In chapter 3, there is a comparison between the safety regulations regarding fire safety that apply on merchant ships nowadays (according to chapter II-2 of SOLAS) and which of them are followed by the navy for this type of ship. Then, Part ΙΙ follows, which consists of 5 chapters. In chapter 4, there is a general presentation of fire simulation models and afterwards, a more thorough examination of FDS (Fire Dynamics Simulator) the simulation model that is used (McGrattan et al., 2014).The model provides safer results for crew survivability that almost represent a real incident. In addition, in chapter 5, there is an in-depth description of the frigate model in FDS, where information referring to the structural elements of the ship, the fire and other theories regarding the experiment is presented. Chapter 6 includes data about the survivability of the crew, where FDS results are presented in the form of diagrams and matrices for all fire scenarios. In order for the procedure to be automated, the computational software Mathematica is used (Wolfram, 1986). In chapter 7, a sea water sprinkler is placed right above the fire in order to see whether crew survivability is raised or not. Eventually, in chapter 8, there a presentation of some ideas for further research regarding fire safety. In conclusion, all fire scenarios are carried out in a medium fire risk room that is far away from the fire engagement team muster station. The ship is considered to be in a state of general alarm (all personnel is in the appropriate positions before engaging into battle) and different cases a	en
