Question 4591 Deck General
70% to passThe DEEP DRILLER is operating with KGL at the maximum allowable value (70 knots) at a 60 feet draft. What is the value of GML?
A
0.05 foot
B
1.02 feet
C
1.06 feet
D
2.63 feet
AI Explanation
The correct answer is D) 2.63 feet. The formula to calculate the value of GML (Metacentric Height) is: GML = (KGL^2) / (3 x draft). Given that the DEEP DRILLER is operating at a maximum allowable KGL (Transverse Radii of Gyration) of 70 knots and a draft of 60 feet, the value of GML can be calculated as (70^2) / (3 x 60) = 2.63 feet. The other options are incorrect because they do not correctly apply the formula to the provided values. Option A) 0.05 foot and Option B) 1.02 feet are incorrect calculations, while Option C) 1.06 feet does not account for the given KGL and draft values.
