Structure Modeling Of Ship Fire And Fire System Failure Analysis

Ship fires are very common in the current ship security and a great risk to ships. Space inships is narrow, and cabin layout is complex and compact. A variety of piping systems isextremely complex, and marine environment is very harsh. These things make relief worksvery difficult to implement. Ship fires not only seriously affect the ship’s military strength, butalso is a direct threat to the vitality of the ship. Ship fires will lead to serious casualties andhuge property losses, and even a huge damage to the environment. Therefore, study of fireships becomes more and more popular and in-depth.Kiev-class aircraft carrier has been a tour ship since retired. In this paper, the object ofstudy is Kiev-class aircraft carrier, based on it to establish the approximate structural model ofthe ship. In the paper, choosing the Kiev-class aircraft carrier as the object of study has tworeasons. First, as a tour ship it has been unlock, and the data on it is very abundant and exact.Secondly, it is typical for the fire of ship. Most previous studies focused on a singlecompartment fire of the hazard analysis. This paper attempts to regard the ship as a whole,and use the differences on the mechanism of the fire to divide all of compartments into fourcategories compartments. The garage, flight deck, engine room and hospital are all typicalcompartments.The author uses fault tree to complete fire hazard analysis of the fourcompartments.Otherwise,This paper has also completed the ship fire alarm system failure analysis.From the occurrence to shape, ship fires need two conditions. One is that the fire ignitionsource catches fire.The other one is fire alarm system failure. So this article establishedintegration protection fault tree model contained fire hazard analysis and failure analysis of afire alarm system. As the process is complex and contains large amount of computation, thisarticle only established the garage model for the study. Based on a quantitative analysis, itcompleted the qualitative analysis,and a brief summary of the results. The future use ofcomplex systems theory provide the basis for ship fire study.Finally,in allusion to problems and vulnerabilities on fire protection system for ship, thisarticle put forward counter measures and several suggestions.In the future,it can provide thetheory support for ship fires fighting.
