Exam Question

### Principle of Calculation
This problem is solved by considering two distinct events occurring simultaneously after the grounding:
1. **Change in Mass:** The teak lining is torn off, resulting in a reduction of the barge's total mass. This will cause an initial decrease in draught.
2. **Loss of Buoyancy (Bilging):** The mid-length compartment is laid open to the sea. According to the 'Lost Buoyancy' method, the volume of buoyancy provided by this compartment up to the waterline is lost. To compensate for this loss, the remaining intact parts of the vessel must sink deeper, increasing the draught.
