PRESENTATION CONTENTS

1. Determination of Preliminary Principal particulars2. Preliminary lightweight, deadweight and displacement3. Preliminary General Arrangement4. Preliminary Lines Plan5. Preliminary Hydrostatic Calculations

Finding Preliminary Principal Particulars

As per “DOS” (Department Of Shipping) Bangladesh and BIWTA:For inland vessels we have following restrictions:Loa will not exceed 76.2 mB mld will not exceed 15 mDraft mld will not exceed 3.96 m

Principal particulars:

We have length, breadth and draft restrictions as we have to move inland. For first assumption, we are have taken these restrictions as our principal particulars.

Deadweight=2900 tonnes Assumed Cd =0.8 Displacement= 2900/0.8 =3625 tonnes Lightweight= (3625 ─ 2900) =725 tonnes Loa=76.2 m

Principal particulars

Lbp= 96% of Loa = 73.152 m Bmld=15 m Draftmld=3.96 m Speed=10 knots Cb= 0.83

Preliminary Principal Particulars

LOA 76.2 m

LBP 73.152 m

Breadth mld 15m

Depth mld 5.94.m

Draught 3.96 m

Cb 0.83

Speed 10 knots

Displacement = deadweight / deadweight co efficient = 2900 / 0.8 =3625tonnes

Light weight = displacement – dead weight = 3625 – 2900= 725 tonnes

Preliminary Lightweight, Deadweight and Displacement:

Category QuantityFuel 14.539tonnes

Weight of people 1.275 tonnes

Fresh water 12.58 tonnes

Provisions & stores 0.85 tonnes

Cargo oil = 2900– 29.668 = 2870.332 tonnes
