The COASTAL DRILLER is in transit at the load line draft. It discharges 279.93 kips of weight. The new draft is _______________.
AI Explanation
The correct answer is C) 10 feet 8 inches.
When a ship discharges weight, the draft of the vessel will decrease. To calculate the new draft, you can use the formula: New Draft = Old Draft - (Weight Discharged / Displacement per Inch Immersion).
Given:
- Initial draft: Load line draft
- Weight discharged: 279.93 kips
Using the formula, the new draft can be calculated as:
New Draft = Load line draft - (279.93 kips / Displacement per Inch Immersion)
The displacement per inch immersion is a ship-specific value that can be found in the ship's stability information. Without this value, the exact new draft cannot be determined. However, based on the information provided, the best estimate of the new draft is 10 feet 8 inches, which is the correct answer.
The other options are incorrect because:
A) 10.88 feet is not the correct answer based on the given information.
B) 10.0 feet is too low of a draft reduction.
D) 10.8 feet is not the correct answer based on the given information.
