Question 4659 Deck General

The correct answer is B) increased capacity to set flooding boundaries. In MODU (Mobile Offshore Drilling Unit) construction, a greater number of watertight bulkheads results in increased capacity to set flooding boundaries. This is because more watertight compartments created by the bulkheads allow the vessel to better contain and control the spread of floodwater in the event of a breach, thereby improving the vessel's overall stability and survivability. The other options are incorrect: A) is incorrect because the number of watertight bulkheads does not directly affect deck load capacity; C) is incorrect because more bulkheads increase, not decrease, the capacity to set flooding boundaries; and D) is incorrect because more compartmentation, not less, is achieved through a greater number of watertight bulkheads.
