- 1. a tour of new featuresENGINE ROOM FIXED FIREFIGHTING SYSTEMCARBON DI OXIDE
- 2. EnhancingPresentation132IntroductionConclusionExplanationIt have features for every step of the way
- 3. IntroductionTo Presentation1Its 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 projectBasic WorkingSpecificationsCo2 gas cylinder: 45 kg Co2 gas filled Height - 1640 mm Width - 267 mm Pressure – 58 barDischarge Nozzle: Total flooding Type Material – Brass ½” NPT internal ConnectionDischarge Pipes : Seamless steel pipes ASTM A106 Gr.B ½” and ¾” outer diameter Elongation 20%Pipe fittings : Socket Weld fittings Forged steel (Galvanised) BS3799 ANSI B16.11 - 2001
- 18. 2Explanation & calculationsCalculate, Testing and Proving the Results
- 19. TEST RESULTSVolume of Engine room before 20% volume increase = 739.12m3Volume of Engine room after 20% volume increase = 886.94 m3Mass of Co2 gas required after volume increased = 59.24 m3Total mass added to ship = 0.2492 tonneBodily sinkage of ship = 0.0311 cm
- 20. Getting Startedwith Frames 30 - 60Frames 54 - 60Area 1 = 44.91 m2Volume 1 = 164.286 m3By taking average height from frames 30 – 54, the following volume calculations been done.Frames 30 - 54Area 2 = 39.29 m2Volume 2 = 574.82 m3TOTAL VOLUME = 739.114 m3
- 21. OTHER CALCULATIONSVolume without casing and comparing both volume according SOLAS Regulations. CO2 mass calculations.
- 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.3ConculsionFrom 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 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
