Exam Question

At a draught of 1.0 m in sea water density 1025 kg/m3 the dispalcement of a ship is 900 tonne and the height of the centre of buoyancy above the keel (KB) is 0.6 m. Values of tonne per centimeter immersion (TPC) in sea water for a range of draught are given in the table.

(Table will be here soon)

(a) Calcualte EACH of the following for a draught of 6.0m in sea water

(i) The displacement

(ii) The height of the centre of buoyancy above the keel

(b) At a draught of 6.0m, the height of the longitudinal metacentre above the keel (KML) is 128m and the second moment of are of the waterplane above a transverse axis through midship is 996728m4. The centre of flotation is aft of midships. Calculate the distance of the centre of flotation (LCF) from midship.
