315 tonnes m But if the ship is to complete the operation upright:
The ship will therefore be brought upright by transferring 26.25 tonnes from starboard to port.
From this it can be seen that, to bring the ship to the required trim and upright, 120 tonnes of oil must be transferred from forward to aft and 26.25 tonnes from starboard to port. This result can be obtained by taking 120 tonnes from No. 2 starboard and by putting 93.75 tonnes of this oil in No. 5 starboard and the remaining 26.25 tonnes in No. 5 Port tank.
The distributions would then be as follows:
Note. There are, of course, alternative methods by which this result could have been obtained, but in each case a total of 120 tonnes of oil must be transferred aft and 26.25 tonnes must be transferred from starboard to port.
