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
4. Objectives To Achieve

To calculate the volume of engine room excluding casing. 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. 17. To estimate the total cost of the project

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
Volume1= 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
Volume2= 574.82 m3
TOTAL VOLUME= 739.114 m3
21. OTHER CALCULATIONS

Volume without casing and comparing both

volume according SOLAS Regulations.

CO2 mass calculations. 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. 27. Finally Cost Caluculations.

Conculsion
From those calculations and report, the requirement of new and extra instalations had done to the ferry company according solas regulations.
Opinion by reasoning for seamless delivery
28. What is the final recommendation ?Hover over the video and youll 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 timesfaster than others. And More efficient too.
Co2 Gas Discharging about to suppress
