Question 5084Deck General70% to pass
The DEEP DRILLER is loaded as shown in the Sample Load Form Number 5 (Survival) when an unexpected slowly increasing starboard list and bow down trim occurs. A leak in 1S is found. By deballasting from ballast tanks 2S and 3S, the inclination slowly decreases. The increase in the transverse free surface corrections is _______________.
AI Explanation
The correct answer is D) 0.22 foot.
The increase in the transverse free surface correction is related to the reduction in the amount of liquid in the ballast tanks. As the liquid level in the ballast tanks decreases, the free surface effect also decreases, leading to a smaller transverse free surface correction.
The other options are incorrect because they do not accurately reflect the decrease in the transverse free surface correction due to the deballasting of tanks 2S and 3S. Option A (1.25 feet) and Option B (0.90 foot) are too high, while Option C (0.84 foot) is also inaccurate.
