DEVELOPMENT AND APPLICATION OF SIMULATORALGORITHM IN ACCORDANCE WITH SHIP MAIN ENGINEAUXILIARY SYSTEMSKaan ÜnlügençoğluYildiz Technical University, Naval Arch. & <strong>Maritime</strong> Faculty, Istanbul, Turkey,E-mail: kunlu@yildiz.edu.trFuat AlarçinYildiz Technical University, Naval Arch. & <strong>Maritime</strong> Faculty, Istanbul, Turkey,E-mail: alarcin@yildiz.edu.trAbstractShip engine room has a detailed structure so that it should meet all the requirements related to operatingconditions simultaneously. According to naval statistical analyses, one of the most important causes ofshipwrecks is human error. Because of this reason, if precautions are not applied, both engine room’scomplicated structure and human errors may cause bigger problems and engine breakdown which maylead to irreparable failure. An effective expert system is necessary for early intervention to prevent allkinds of engine breakdown immediately. This study aims to manage troubleshooting in main engineauxiliary systems which cover cooling, lubricating and cooling oil and fuel systems. The study is alsothought to be a good reference for maintenance processes for ship engine officers.Keywords: engine room simulator, expert system, troubleshooting, central cooling systemIntroductionThe engine room includes; main engine and auxiliary engines such as boiler, fuel systems,lubrication system, exhaust system and cooling system. The engine room designed to be able to work formultiple needs in different operating conditions. In this point, the effects of variable operating conditionsand various kind of scenarios depends on both operators and structural features.According to the Naval Statistics Analyses; shipwrecks happened mostly due to human errors. Sincehuman factor is very important, Naval Industry to search for safer solutions (1) (2) (3) (4). Except thismotivation, especially on maneuvering positions and engine troubles in special areas also necessitatedemergency solutions strategies.Engine trouble could be explained as; if the engine or the systems being worked improperlyexceeding the engine values or suddenly stopped working, and to loss all the control of engine operations.In the engine room, all engines work in an integrated manner and due to this reason, any fault happeningin any system can quickly affect the whole system. A small fault may grow to a fault of the whole systemto turn the situation into a life-threating danger. This shows that in any case of engine breakdown orfailure, the crew needs to address the problem as quick as possible. To prevent faults happening or toresolve an existing problem, the most educated and experienced engineers must work and to determinethe faults earlier, expert diagnosis system must be used. Besides, directing all the crews properly willcreate a safer work environment leading to the minimization of the economical losses.In this study, expert diagnosis system is developed for cooling, lubrication and fuel systems of mainengine auxiliaries. Furthermore, the developed system may also play a role in preventive maintenanceprocesses. The main principle of diagnosis system is based on the following logic: The system will alarmany faults that may happen during an operation and serve the basic causes that exists inside the program’sdatabase to the user and the user will be able to select any one of them according to his/her experience. Inthe expert system, the user will determine the faults according to the selected cause and see the reasons ofthe fault with all the possible intervention methods. The information established to the program’sdatabase for determining the faults are derived from the catalogues and manuals supplied from the mainengine manufacturers and experiences gained while operation.Plug-in softwares, especially softwares related to engine system maintenance processes, reduceerrors arising from work load and fatigue of engine operators. Addition of diagnosis modules to thesesoftwares will prevent errors growing bigger.Artificial intelligence softwares named PROLOG and LIPS were found to be used when a briefliterature work is done about this subject [5]. In this study, information based expert system is developed61
