Assigned ProjectDesign of a 2900 DWT Oil TankerRoute: Chittagong-DhakaService Speed: 10 knots

Route Specifications:

Water ways distance---350 kmMaximum Draft-------3.96 mMaximum Length-----76.2 mMaximum Breadth ----15.0 m

PRESENTATION CONTENTS1. 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 tonnesAssumed Cd =0.8Displacement= 2900/0.8 =3625 tonnesLightweight= (3625 2900) =725 tonnesLoa=76.2 m
