OBJECTIVES ,[object Object],[object Object],[object Object],[object Object],[object Object]

Inland Water Transport Network by Category Class Indicated Draft Length in Km. Classification criteria I 3.6 meter 683 at least 3.6 m required to maintain round the year. II 2.1 meter 1000 major inland ports or place of economic importance to class I routes. III 1.5 meter 1885 seasonal in nature IV <1.5 meter 2400 in dry season no navigability Total 5968

DETERMINATION OF PRINCIPAL PARTICULARS ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

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

PRINCIPAL PARTICULARS ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

DISPLACEMENT ESTIMATION ,[object Object],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

DISPLACEMENT ESTIMATION ,[object Object],[object Object],[object Object],[object Object],∆ = DWT / C D = (42.97 / 0.35) tonnes = 122.77 tonnes. Light Weight = ∆ - DWT = ( 122.77 – 42.97) tonnes = 79.8 tonnes

Formula used in hydrostatic calculation ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

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.

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.)
