my project

1. a tour of new features ENGINE ROOM FIXED FIREFIGHTING SYSTEM CARBON DI OXIDE

2. EnhancingPresentation 1 3 2 Introduction Conclusion Explanation It have features for every step of the way

3. IntroductionTo Presentation 1 Its about fire suppression system in engine room using Co2. This project explains the extra requirement of the firefighting system when Engine room volume is increased by 20%. This is done for a ferry company according to their requirement. Design, organize, and collaborate

5. To calculate the volume of engine room including casing.

6. To calculate the mass of Co2 gas required.

7. To determine the number of Co2 gas cylinders.

8. To increase the volume of engine room by 20% of its actual volume.

9. To calculate the mass of Co2 gas required after increase in volume.

10. To determine the final number of Co2 gas cylinders required.

11. To find the bodily sinkage of ship due to new added mass.

12. To determine the correct material and required length of pipe for piping.

13. To determine the pipe fittings for extra installation.

14. To calculate the minimum flow rate of Co2 gas through nozzles.

15. To find the suitable and number of discharge nozzle.

16. To estimate the cost of extra Co2 cylinders, pipes, pipe fittings and discharge nozzles.

18. 2 Explanation & calculations Calculate, Testing and Proving the Results

19. TEST RESULTS Volume of Engine room before 20% volume increase = 739.12m3 Volume of Engine room after 20% volume increase = 886.94 m3 Mass of Co2 gas required after volume increased = 59.24 m3 Total mass added to ship = 0.2492 tonne Bodily sinkage of ship = 0.0311 cm

20. Getting Startedwith Frames 30 - 60 Frames 54 - 60 Area 1 = 44.91 m2 Volume 1 = 164.286 m3 By taking average height from frames 30 – 54, the following volume calculations been done. Frames 30 - 54 Area 2 = 39.29 m2 Volume 2 = 574.82 m3 TOTAL VOLUME = 739.114 m3

22. 20% Volume increasing.

23. Again Mass of Gas required for increased volume.

24. Number of cylinders Required.

25. Bodily sinkage of ship

26. Required pipes, pipe fitting and nozzles.

28. What is the final recommendation ?Hover over the video and you’ll be pleasantly surprised. Finally I would like to recommend the Total flooding DischargeNozzles instead of using 180° or 360° nozzles. Because the total flooding type discharge the Co2 gas 5 times faster than others. And More efficient too. Co2 Gas Discharging about to suppress
