Q16. An inclining test carried out on a passenger vessel at a displacement of 8725 tonne in water of density 1012 kg/m3 resulted in an angle of heel of 1.5º when an inclining mass of 10 tonne was moved 15 m transversely across the deck.
To obtain the lightship condition for the vessel, corrections for the following masses are required:
40 tonne to be removed at Kg 9.2 m
65 tonne to be added at Kg 10.15 m
The following masses in Table Q2 are to be added to give the load condition:
In the above condition, free surfaces of liquid are present in one rectangular tank 8m long and 6m wide containing fresh water of density 1000 kg/m3 and in four rectangular tanks each 10 m long and 8 m wide containing oil fuel of density 950 kg/m3.
Using the hydrostatic curves provided in Worksheet Q2, determine EACH of the following:
(a) The lightship KG;
(b) The final mean draught in sea water;
(c) The final effective metacentric height.
