Q3) A ship of 125 m length has the following particulars when floating in sea water of density 1025 kg/m3 .
Displacement = 11923 tonne
Draught aft = 7.244 m
Draught forward = 6.844 m
Longitundinal metacentric height (GML) = 130 m
Longitudinal centre of floating (LCF) = 2.5 m aft of midships
Tonne per centimetre immersion (TPC) = 18.5
TWO tanks, EACH contanining a substantial quantity of water ballast, are situated with their centres of gravity 50 m aft of midships and 25 m forward of midships respectively.
The vessel is required to enter dock with a draught aft of 7.0 m and a trim of 0.6 m by the stern.
Calculate the mass of ballast to be removed from each tank. (16)
