Question 4906Deck General70% to pass
The COASTAL DRILLER is loaded as shown in the Sample Load Form Number 1 (Rig Move). If the drill water in drill water tanks 6 and 25 are discharged, what is the new draft?
AI Explanation
The correct answer is B) 10.66 feet.
When the drill water in tanks 6 and 25 are discharged, the vessel's overall weight and displacement decrease, resulting in a reduction in draft. The Sample Load Form Number 1 (Rig Move) provides the necessary information to calculate the new draft after the discharge.
The other options are incorrect because:
A) 8.26 feet is too low, as the vessel's draft would not decrease that significantly.
C) 10.88 feet and D) 11.10 feet are too high, as the draft would decrease after the discharge of the drill water.
