Question 156Safety & Environmental - Assistant Engineer
70% to passWhat effect will transferring fuel oil from No.1P double bottom to No.3P double bottom have on the trim of a vessel?
AThe after draft will decrease.
BThe mean draft will decrease.
CThe mean draft will increase.
DThe forward draft will decrease.
AI Explanation
The correct answer is D) The forward draft will decrease. Transferring fuel oil from the No.1P double bottom to the No.3P double bottom will shift the center of gravity aft, causing the vessel's trim to change. As fuel is moved aft, the vessel's bow will rise and the forward draft will decrease, while the after draft will increase. This shift in trim is a direct result of the change in the vessel's weight distribution. The other options are incorrect because: A) The after draft will increase, not decrease. B) The mean draft will remain the same, as the total displacement of the vessel is unchanged. C) The mean draft will not increase, as the total displacement is unchanged.
