Question 1759 Deck Safety

70% to pass

Intact buoyancy is a term used to describe _______________.

A an intact space which can be flooded without causing a ship to sink
B the space at which all the vertical upward forces of buoyancy are considered to be concentrated
C an intact space below the surface of a flooded area
D the volume of all intact spaces above the waterline
AI Explanation

The correct answer is C) an intact space below the surface of a flooded area. Intact buoyancy refers to the buoyancy provided by spaces on a ship that remain intact and floodable, but do not cause the ship to sink. These intact spaces below the waterline contribute to the overall buoyancy of the vessel, even when other areas are flooded. This is an important consideration in ship stability and damage control. The other options are incorrect because they do not accurately describe the definition of intact buoyancy. Option A refers to the general concept of floodable spaces, option B describes the center of buoyancy, and option D refers to spaces above the waterline, which are not considered part of the intact buoyancy.
