Q13. A coastal tanker has a breadth of 16 m and in the lightship condition, has a displacement of 2600 tonne and a KG of 3.34 m.
The vessel is now loaded as indicated in Table Q2.
The following tanks are partially full with liquid as follows:
One rectangular slop tank 10 m long and 8 m wide, containing fresh water of density 1000 kg/m3 with oil of density 900 kg/m3 floating on top;
Four full width rectangular tanks, carrying crude oil of density 952 kg/m3, each 20 m long with centerline oil-tight bulkheads.
In this condition, when floating in sea water of density 1025 kg/m3 the height of the transverse metacenter above the keel (KM) is 5.286 m.
(a) Calculate the effective metacentric height in the loaded condition.
(b) (i) Using Worksheet Q2, draw the curve of statical stability for the loaded condition.
(ii) From the curve drawn in Q2 (b) (i), determine the range of stability
