  11. 11. LBP 25.79/LBP =1.05 = 24.4 m Breadth (B) 24.4/B= 3.87 = 6.30 m Draft (T) 6.30/T = 4.20 = 1.5 m Depth (D) D/1.5= 1.73 = 2.6 m
  12. 12. PRINCIPAL PARTICULARS <ul><li>Length Overall 25.79meter </li></ul><ul><li>LBP 24.4 meter </li></ul><ul><li>Breadth (moulded) 6.3 meter </li></ul><ul><li>Depth 2.6 meter </li></ul><ul><li>Max. Draught(moulded) 1.5 meter </li></ul><ul><li>(at full load) </li></ul>
  13. 13. DISPLACEMENT ESTIMATION <ul><li>DEADWEIGHT (DWT) CALCULATION : </li></ul>No of Person on board: No of passenger = 95 No of crew = 4 Total = 99 Weight Allowance per person: Weight per person = 75 kg Fresh water per person = 1 liter Luggage = 5 kg Total = 81kg Fuel needed per voyage : 500 liter Store + Allowance : 1000 kg Total Weight : (95*81) + (500*.80) + 1000 = 32.495 tonnes Cargo: (95*5)=0.475 tonnes Allowance : 10 tonnes Deadweight : Total weight + Cargo+Allowance = (32.495+.475+10)=42.97tonnes
  14. 14. DISPLACEMENT ESTIMATION <ul><li>LIGHT WEIGHT & DISPLACEMENT CALCULATION </li></ul><ul><li>Deadweight Coefficient : 0.35(Assuming) </li></ul><ul><li>Displacement : </li></ul><ul><li>Lightship : </li></ul>∆ = DWT / C D = (42.97 / 0.35) tonnes = 122.77 tonnes. Light Weight = ∆ - DWT = ( 122.77 – 42.97) tonnes = 79.8 tonnes

  24. 24. Formula used in hydrostatic calculation <ul><li>Water plane Area : </li></ul><ul><li>In our lines plane we take total 11 Station. Multiplying the half ordinate of each station with the multipliers used in simpson’s first rule we find total product for area. Then, </li></ul><ul><li>Water plane area = 2 X h L /3 X total Product for area </li></ul><ul><li>Displacement : </li></ul><ul><li>In our lines plane we take total 4 water lines. After finding different water plane area </li></ul><ul><li>we use 5,8,-1 rule, simpson,s first rule & simpson’s second rule to find volume up to different water line. As our ship is an Inland waterways ship so Displacement is equals to volume. </li></ul><ul><li>Volume up to water line 1 = 1/12 X h v X Total Product for volume (By using 5,8,-1 rule). </li></ul><ul><li>Volume up to water line 2 = 1/3 X h v X Total Product for volume </li></ul><ul><li>(Using Simpson’s First rule). </li></ul><ul><li>Volume up to water line 3 = 3/8 X h v X Total Product for volume </li></ul><ul><li>(Using Simpson’s Second rule). </li></ul><ul><li>Volume up to water line 4 = 1/3 X h v X Total Product for volume </li></ul>
  25. 25. Formula Used in Hydrostatic Calculation: Positions of Center of Buoyancy above keel ( KB ) : KB = Moment of Volume Displacement above base / Volume up to corresponding waterline Positions of Longitudinal Metacenter (BM L ) : BM L = Moment of Inertia about center of flotation ( I L ) / Displacement of volume Moment to Change trim 1m ( MCT 1m ) : MCT 1m = (I L X Displacement in ton ) / (L BP X Displacement in volume) Positions of Transverse Metacenter (BM T ) : BM T = Transverse Moment of Inertia / Moment of Volume.
  26. 26. Formula Used in Hydrostatic Calculation: Block Coefficient (C B ): C B = Displacement in Volume / (L BP X B X draught at corresponding water plane.) Midship Area Coefficient (C m ) : C m = Midship Section Area / (B X draught at corresponding water plane.) Prismatic Coefficient (C p ) : C p = C B / C m Water plane Coefficient (C w ) : C w = Water plane Area / (B X L at corresponding water plane.)
