1. Bangladesh university of engineering & technology NAME 338 SHIP DESIGN PROJECT & PRESENTATION-II DATE-25 OCTOBER,2010

2. DESIGN OF A WATER TAXI FOR 95 PASSENGERS in SADARGHAT-ASHULIA ROUTE Project Supervisor KhabirulHaqueChowdhury Professor Department of Naval Architecture & Marine Engineering,BUET Presented By- Hasib-Ul-Haque (0712014) Ahmad ShibliSaleheen (0712018)

4. To ease the water way communication with comfortable service.

5. To reduce the pressure on land transport.

6. To safe people from horrible traffic jam.

8. DETAIL DEADWEIGHT & LIGHTWEIGHT CALCULATION

10. GENERAL ARRANGEMENT

12. SCANTLING CALCULATION We have used ISSA rule book for our scantling calculation

18. Deadweight calculation

19. DEADWEIGHT CALCULATION No of person on board: No of passenger = 100 No of crew = 6 Total = 106 Weight allowance per person: Weight per person = 75 kg Luggage per person = 5 kg Total = 80 kg Total weight for persons = 80× 106 = 8.48 tons

20. Capacity calculation

21. Sample CALCULATION OF Fresh water tanK (PORT & STARBOARD SIDE) Station spacing = 1.575 m Volume of tank= 6.7 m3 Weight of fresh water= 6.7 tons

22. SAMPLE CALCULATION OF Fuel tank (PORT & STARBOARD SIDE) Station spacing = 1.8 m Volume of tank= 0.83m3 Weight of disel oil= 0.75tons

23. Summary of deadweight

24. Lightweight calculation

25. SHELL EXPANSION

26. CALCULATION OF WEIGHT OF PLATES

27. weight of other items

28. WEIGHT OF OTHER ITEMS

29. So,the total lightweight of the vessel is = (11.3+61.25) tons = 72.55 tons Therefore, the displacement of the vessel= Lightweight+Deadweight = 72.55 + 44.96 = 117.51 tons Which was previously 123.48 tons

30. STABILITY & TRIM CALCULATION

31. STABILITY CALCULATION

32. GZ SAMPLE CALCULATION AT 30°INCLINATION

33. GZ SAMPLE CALCULATION AT 30° INCLINATION Volume of the Layer(1/2*(1/3*2.43)*(1/3*.2616)*373.607)*2= 26.39352 m3 V.C.G from keel= 2.08 m KB = 0.92 m

34. GZ CURVE

35. COMPARISON WITH IMO 167 REGULATION FOR STABILITY CRITERIA

36. TRIM CALCULATION LCB At LWL = 1.12 m aft of amidship LCG of total ship = 1.29 m aft of amidship Displacement of the Ship = 123.48 tonne At LWL, MCT1m = 189.77 tonne-m C.F. = 1.22 m aft of amidship Draft = 1.5 m [The value of LCB,MCT1m,C.F. are taken from the Hydrostatic Calculations earlier in the design procedure]

37. TRIM CALCULATION Now,Amount of Trim={(1.29-1.12)*123.48}/189.77 = 0.1106 m So, Change in Trim aft= 0.05 mChange in Trim Forward= 0.06 m Therefore, resulting Draft Forward= 1.5+0.06 = 1.56 m Draft Aft= 1.5- 0.05 = 1.45 m
