Thesis entitled Ship Fire Alarm Systems and Functional Analysis study the role of a fire alarm system in protecting a ship from a potential fire. In the first part of the paper, the basic characteristics of ship fire alarm systems are studied, with an emphasis on the fire alarm system as a key factor in the development of fire alarm systems. The development of modern technology has enabled progress in the structure of the system, emphasizing the address systems where it is possible to determine the exact location of the fire, which significantly contributes to the safety of the crew and the ship. With the progress of the system itself, at the same time, the reliability and availability of the fire alarm system increase. An important part of the research leads to the analysis of ship fires. The engine room stands out as an area of special risk, considering that more than 50% of ship fires occurred in that area. Fires on passenger ships are necessarily specifically analyzed given the complexity of such ships and the presence of a significant number of people. The results of the research show that the development of technology enables faster and more accurate fire detection, which achieves significant progress in ship safety.
