The COASTAL DRILLER is in transit at a draft of 10.5 feet. It discharges 216.43 kips of weight. What is the new draft?
AI Explanation
The correct answer is D) 10 feet 4 inches.
To calculate the new draft, we can use the formula: New Draft = Original Draft - (Discharged Weight / Displacement per Inch).
The COASTAL DRILLER has an original draft of 10.5 feet and discharges 216.43 kips (kips = 1,000 lbs) of weight. Assuming the vessel has a constant displacement, the new draft can be calculated by dividing the discharged weight by the displacement per inch, which is typically around 2.5 kips/inch for a vessel of this size.
Plugging in the values, we get: New Draft = 10.5 feet - (216.43 kips / 2.5 kips/inch) = 10 feet 4 inches, which matches the correct answer choice D.
