Question 4998 Deck General

70% to pass

The COASTAL DRILLER is loaded as shown in the Sample Load Form Number 1 (Rig Move). If the contents of the No.7 drill water tank are discharged, what would be the new TCG?

A -0.15 foot
B 0.00 foot
C 0.15 foot
D 0.29 foot
AI Explanation

The correct answer is C) 0.15 foot. When the contents of the No.7 drill water tank are discharged, the overall weight of the vessel decreases, which causes the TCG (Transverse Center of Gravity) to shift towards the centerline. This shift in TCG results in an increase of 0.15 foot in the new TCG value. The other options are incorrect because: A) -0.15 foot would indicate a shift of the TCG in the opposite direction, which is not the case. B) 0.00 foot would mean no change in the TCG, which is not accurate. D) 0.29 foot is an incorrect value, as the shift in TCG should be 0.15 foot.
