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