70% to pass

Many vessels are provided with flume tanks, which also have a dump tank located under the flume tanks. In the event the ship is damaged, you could dump the flume tanks into the dump tank which would _______________.

A not have any effect on free surface and raise the KG
B not have any effect on free surface and lower the KG
C reduce the free surface effect and raise the KG
D reduce the free surface effect and lower the KG
AI Explanation

The correct answer is D) reduce the free surface effect and lower the KG. When a ship's flume tanks are flooded, the free surface effect causes the ship's center of gravity (KG) to rise, reducing the ship's stability. By dumping the flume tanks into the dump tank, the free surface effect is reduced, which in turn lowers the ship's KG and improves its stability. The other options are incorrect because: A) and B) state that there would be no effect on the free surface, which is not accurate. C) indicates that the KG would increase, which is the opposite of what happens when reducing the free surface effect.
