In the main interface as given in Figure 4, if the related system is selected, working parameters inputdisplay can be seen as given in Figure 5. As the system is selected, database of the chosen system is savedin the memory. In the current system, these parameters are input manually. Besides, these parameters canbe gathered by sensors in a real engine room system. In a manual input, the parameters can be saved inthe memory by “Save” button.Figure 5. Operating parameters input screen of central cooling systemWhen the “Default Values” button is selected (shown in Figure 5), the ideal operating values of thesystem is screened as is the case shown in figure 6. The given values are the ideal running and alarm limitvalues of the central cooling water system of MAN B&W 7S50MC-C. These values are shown in detailin Table 2. If desired, the program can accept the ideal running values of different model and type of mainengines as well.Figure 6. Optimum operating parameters screen of central cooling system67
