Question 4731Deck General70% to pass
With no environmental forces on the DEEP DRILLER, the average of the forward drafts is 61.0 feet, and the average of the aft drafts is 59.0 feet. KGL is 51.13 feet. What is the value of LCG?
AI Explanation
The correct answer is D) 2.35 feet.
The formula to calculate the Longitudinal Center of Gravity (LCG) is: LCG = KGL + (Forward Draft - Aft Draft) / 2.
Given:
- Average Forward Draft = 61.0 feet
- Average Aft Draft = 59.0 feet
- KGL = 51.13 feet
Plugging these values into the formula:
LCG = 51.13 + (61.0 - 59.0) / 2
LCG = 51.13 + 1.0 / 2
LCG = 51.13 + 0.5
LCG = 2.35 feet
The other options are incorrect because they do not correctly apply the formula to calculate the LCG based on the given information.
