The term 'void' on a vessel refers specifically to an empty compartment below decks. These void spaces are intentionally designed and constructed as unoccupied areas within the ship's hull or superstructure. They serve several important functions, such as providing structural integrity and reducing weight, and they can also be utilized for buoyancy control, allowing the vessel to maintain stability.

In construction terminology, voids are often part of large compartments that are not filled with cargo, equipment, or other materials, making them separate from other functional areas of the ship. Understanding the concept of voids is vital for both ship design and maintenance, as these spaces often require inspection for the detection of leaks or structural issues.
