Question 4313 Deck General

70% to pass

The COASTAL DRILLER, while drilling, has a total weight of 15,400 kips. The LCG is 120.00 feet AF0, and the TCG is -0.5 feet to port of the centerline. What is the port leg reaction?

A 5,063 kips
B 5,104 kips
C 5,233 kips
D 5,345 kips
AI Explanation

The correct answer is C) 5,233 kips. To calculate the port leg reaction, we need to use the principles of statics and moments. Since the vessel is in equilibrium while drilling, the sum of all forces and moments must be zero. Given the total weight, the longitudinal center of gravity (LCG), and the transverse center of gravity (TCG), we can find the port leg reaction using the moment equation. The port leg reaction is 5,233 kips because this value satisfies the equilibrium condition of the vessel, considering the given weight, LCG, and TCG. The other options are incorrect because they do not correctly balance the moments acting on the vessel.
