Q2. Table Q2 gives values of righting levers (GZ) relating to a ship of 12000 tonne displacement in a particular load condition:

In the above condition the ship has 320 tonne of fuel stored in a double bottom tank which has to be emptied for survey. This oil is transferred to a wing deep tank, through a transverse distance of 7.5 m and a vertical height of 5.25 m.

(a) Draw the amended curve of statical stability, neglecting the effects of free surface. (12)

(b) Determine EACH of the following, from the curve drawn in Q2(a):

(i) the angle to which the ship will list; (1)

(ii) the range of stability. (1)

(c) Determine the righting moment at an angle of 25o. (2)
