Q5) A box shaped barge of uniform construction is 80 m long , 10 m wide and has a light displacement of 720 tonne. It is divided into three compartments by two transverse watertight bulkheads so that the end compartments are of equal length. The barge is loaded to draught of 6 m in water of density 1025 kg/m3 with cargo evenly distributed over the two end compartments.
The empty midship compartment, extending the full width and depth of the barge is now bilged and the draught increases to 8 m.
(a) Determine the length of the midship compartment. (3)
(b) For the original intact condition:
(i) plot curves of mass and buoyancy distribution; (5)
(ii) determine the longitudinal still water bending moment at midships. (4)
(c) Determine the longitudinal still water bending moment at midships for the final bilged condition. (4)
