Piping System with respect to Crude Oil Washing: The pipeline and valves incorporated in the crude oil washing system shall be of steel or equivalent material and shall have adequate strength having regard to the pressure it may be subjected and shall be properly jointed and supported. The crude oil washing system should contain permanent…
CRUDE OIL WASHING PRECAUTIONS AND PROCEDURES Prior to arrival at the discharge port, the following must be carried out: No C.O.W. is to be started until the Master has satisfied himself that the following has or will be complied with:
Official Log Book means the log book kept at the bridge of the ship in accordance with the provisions of the Merchant Shipping Act. Offical logbook is considered to be a running log of all official events such as Arrival / Departure of the vessel to/from the port, Draughts, Freeboards, Onboard Emergency Drills, Crew onboard, Fuel/Fresh…
ROR Cards – also called Rules of the Road cards are very helpful for learning perspective. These cards show the view forward from the deck of various vessels (power, sailing and fishing) of developing traffic situations at sea. In each case the mariner has to decide the correct course of action to navigate his vessel…
Solution: Ship’s weight KG VM 2000t (load) 4.2m 3400 tm 300t (load) 2.0m (+) 600 tm 200t (load) 3.2m (+) 640 tm 500t (load ) 1.0 m (+)500 tm Final W = 300t …
Solution: Given:- Weight = 8800t,Original KG =6.2m,Cargo loaded = 200t,KG = 1.7m Ship’s weight KG VM 8800 t 6.2m 54560tm (+) 200 load 1.7m Final VM 54900 tm Final W – 9000 t Final VM 54900 tm So, we can calculate Final KG = (Final VM/ Final W)Final KG = (54900 / 9000)= 6.1m Here…
Stability 1 – Chapter 5 Effect of Density Solutions > Exercise 5: Effect of density on draft and displacement – FWA ; DWA ; loadliness of ship. Solution: Displacement (W) = 16000 tTPC = 20 & SW draft = 8.0m We know that: Displacement when in SW = ( L X B x draft) x…
Stability 1 – Chapter 4 Solutions for Exercise 4: Some important terms – displacement; deadweight; form coefficient; reserve buoyancy; Tonnes per centimetre. Solution : Area of box shape vessel = (L x B)= 120m x 15mLight draft = 4m Light displacement = (u/w volume) x ( density)= (L x b x d )x (1.025)= (120…
Solution : Volume of rectangular log = (L x b x h)= (8m x 2m x 2m)= 32m3 Weight = (U/W volume ) x (Density of displaced water)Weight = (8 x 2 x1.6) x(1)= 25. 6t RD = (mass / volume)= 25.6 / 32= 0.8t/m3 . Solution : Volume of rectangular log = (L x B…
Solution : Area of the flat keel plate = (10 x 2) = 20m2 Pressure = (depth x density) = (8 x 1.025) = 8.2t /m2 Thrust = (pressure x area) …
SOLUTION: Given : L =16m , B = 15m, H = 6m, RD=0.7 =16x15x6 = 1440m3 We know that : Density = Mass /Volume0.78 =Mass/1440m3 Hence, Mass =1123.2 tonnes SOLUTION: Given: Diameter = 8m, Radius = (d/2)m=(8/2)m =4mHeight =10mMass = 400tRD =0.9 We know that: Volume of the cylindrical tank = π2h= 3.1416 x 4…
