Q4)  A ship of displacement 14000 tonne has a length 130 m, breadth 17 m, and even keel draught of 6.11 m in sea water of density 1025kg/m³ .

The area of the waterplane is 1600 m² and the second moment of area of the waterplane about a transverse axis through midships 1.25 x 106 m⁴ with the LCF at midships.

The ship has a full depth empty recatangular compartment having length 13 m and breadth 11 m.

The centre of the compartment is on the centreline of the ship 30 m forward of midships.

Calculate the end draughts after the compartment is bilged. (16)

Note: For the purposes of calculating the MCT 1cm it can be assumed that GML = BML
