Q2. Table Q2 gives values of righting levers (GZ) relating to a ship of 10500 tonne displacement in a particular load condition:

In the above condition the ship has 315 tonne of fuel stored in a double bottom tank which has to be emptied for survey. The oil is transferred to a wing deep tank, through a transverse distance of 5 m and a vertical height of 4 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) Calculate the righting moment at an angle of 25^o. (2)
