Question 1753 Deck Safety

70% to pass

How do you determine the weight of the vessel that is supported by the ground when a vessel has run aground?

A Use the hydrostatic tables and enter with the mean draft before grounding and the mean draft after grounding.
B Determine the point where aground and the draft at that point, then calculate it using the grounding formula.
C Use the inclining experiment formula and substitute the change of trim for the angle of list.
D This requires extensive calculation and is usually performed only by a naval architect not by a ship's officer.
AI Explanation

The correct answer is A) Use the hydrostatic tables and enter with the mean draft before grounding and the mean draft after grounding. This is the correct answer because the weight of the vessel supported by the ground when a vessel runs aground can be determined by using the hydrostatic tables. The hydrostatic tables provide information on the vessel's displacement, which corresponds to the weight of the vessel. By entering the mean draft before and after grounding, you can determine the change in displacement, which represents the weight of the vessel supported by the ground. The other options are incorrect because they either require more complex calculations (B and C) or are not typically performed by a ship's officer (D).
