    KhabirulHaqueChowdhury
    Professor
    Department of Naval Architecture & Marine Engineering,BUET
    Presented By-
    Hasib-Ul-Haque (0712014)
    Ahmad ShibliSaleheen (0712018)
  • 3. OBJECTIVES
    To use the circular water ways around Dhaka city
    To ease the water way communication with comfortable service
    To reduce the pressure on land transport.
    To safe people from horrible traffic jam.
  • 4. PRINCIPAL PARTICULARS
    LENGTH:
    OVERALL : 24.90 meter
    Load water line : 24.122 meter
    L.B.P : 22.95 meter
    BREADTH:
    MAXIMUM : 6.5 meter
    MOULDED : 6.3 meter
    DEPTH(MLD) : 2.0 meter
    DRAFT(MLD) : 1.1 meter
  • 5. PRESENTATION TOPICS
    1.Rudder design.
    2.Engine selection and foundation.
    3.GA and Lines plan update
    4.Weight calculation update
    5.Hydrostatic calculation update
    6. Trim and Stability update
  • 6. Rudder Design-Calculation from GL
  • 7. CAD Drawing
  • 8. Steering Arrangement
  • 9. Resistance & Power CalculationHoltrop Mennen Method
    RT = RF(1+K1) + RAPP + RW + RB + RTR + RA
    Where,
    • RF = Frictional resistance according to ITTC 1957 friction formula
    • 10. (1+K1) = Form factor describing the viscous resistance of the hull form in relation to RF
    • 11. RAPP = Appendage resistance
    • 12. RW = Wave making and wave breaking resistance
    • 13. RB = Additional pressure resistance due to bulbous bow near the water surface
    • 14. RTR = Additional pressure resistance of immersed transom stern
    • 15. RA = Model ship correlation resistance
     
  • 16. Resistance & Power Calculation
     For our ship we get,
    RF= 4.6430 KN
    (1+K1) = 1.22
    RAPP = 0.1417 KN
    RW= 9.0478 KN
    RB = 0
    RTR = 0
    RA = 1.7609 KN
    So, RT = 16.6149 KN
    Effective power,PE = RT × V
    = 16.6149 × 12 ×0.5149
    = 102.65 KW = 137.68 HP
  • 17. Resistance & Power Calculation
    Shaft Power,Ps= PE/[ ηR η0ηs(1-t)/(1-w)] = 188.19 HP
    Delivered Power,PD= ηs× Ps= 0.99 × 188.19 = 186.31 HP
    Break horse power = PS/ ηG = 194.01 HP
    Where,
    ηG= gear efficiency = 97%
  • 18. Engine Selection
    Yanmar type 4JH4-HTE
  • 19. Engine Selection
    Steyr Motor Engines-M0114K33
  • 20. Why we select Yanmar type 4JH4-HTE??
    The Yanmar type 4JH4-HTE Engine is designed for high performance.
    The innovative fuel injection technology enables an excellent torque and speed range.
    Service Life-this engine is manufactured using high alloy materials to provide enduring longevity for all running components.
    Comfort-The patented 2-stage UNIT Injector fuel injection technology provides for a worldwide approped and smooth operation noise
    Exhaust Emissions-The trend-setting UNIT INJECTOR system enables us already today to conform with the valid emission regulations.
    Transmission-this engine allow the installation with different driving system in our boat.

  • 25. Engine Specification
  • 26. Engine Foundation
  • 27. CAD Drawing
  • 28. CAD Drawing
  • 29. CAD Drawings
  • 30. Equipments
  • 31. VARIANCE IN DATA
  • 32. GA Update
  • 33. MODIFICATION OF GENERAL ARRANGEMENT
    1.Canteen facility has been cancelled
    2.Number of Bulkhead is reduced
    4.Seating arrangement has been renovated and updated
    5.Change in Cabin type,size and position
  • 34. Comparison between GA plans
    GA-Updated
    GA-Previous
  • 35. Lines Plan Update
  • 36. Deadweight calculation
  • 37. 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
  • 38. Capacity calculation
  • 39. Summery from Capacity Calculation
  • 40. Summary of deadweight
  • 41. Lightweight calculation
  • 42. SHELL EXPANSION
  • 43. Longitudinal
  • 44. CALCULATION OF WEIGHT OF PLATES
  • 45. weight of other items
  • 46. WEIGHT OF OTHER ITEMS
  • 47. MISCELLANEOUS : 2 TONNE
  • 48. So,the total lightweight of the vessel is = (9.47+47.93) tons
    = 57.4 tons
    Therefore,
    the displacement of the vessel= Lightweight+Deadweight
    = 57.4 + 17.48
    = 74.88 tons
    Which was previously 123.48 tons

  • 65. STABILITY CALCULATION
  • 66. GZ SAMPLE CALCULATION AT 30°INCLINATION
  • 67. GZ SAMPLE CALCULATION AT 30° INCLINATION
    V.C.G from keel= 1.31 m
    KB = 0.69 m
  • 68. GZ CURVE
  • 69. TRIM UPDATE
    • LCB At LWL = 0.72 m aft of amidship
    • 70. LCG of total ship = 0.93 m aft of amidship
    • 71. Displacement of the Ship = 74.68 tonne
    At LWL,
    • MCT1m = 141.16 tonne-m
    • 72. C.F. = 1.08 m aft of amidship
    • 73. Draft = 1.1 m
    [The value of LCB,MCT1m,C.F. are taken from the Hydrostatic Calculations earlier in the design procedure]
  • 74. TRIM UPDATE
    Now,
    Amount of Trim={(0.93-0.72)*74.68}/141.16
    = 0.1111 m by stern
    So,
    Change in Trim aft= 0.05 m
    Change in Trim Forward= 0.061 m
    Therefore, resulting
    Draft Forward= 1.1-0.061 = 1.039 m
    Draft Aft= 1.1+0.05 = 1.15 m
