Question 136Safety & Environmental - Assistant Engineer

The correct answer is C) the total weight of the vessel. The weight of the liquid displaced by a vessel floating in sea water is equal to the total weight of the vessel. This is based on the Archimedes' Principle, which states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. Therefore, the weight of the liquid displaced is equal to the total weight of the vessel, including its contents and structure. The other options are incorrect because they do not directly represent the weight of the liquid displaced. Option A is the volume of the submerged portion of the vessel, not the weight. Option B is the weight required to sink the vessel, which is different from the weight of the liquid displaced. Option D, reserve buoyancy, is the difference between the vessel's buoyancy and its weight, not the weight of the liquid displaced.
