floating dry dock
Definition
Noun: A floating dry dock is a type of dry dock that is not fixed to land. It is a buoyant structure that can be submerged by filling ballast tanks with water. Once submerged, a vessel can be floated into position above it. The dock is then raised by pumping the water out, lifting the vessel completely out of the water for inspection, maintenance, or repair.
Usage
A floating dry dock is used in shipyards and harbors. It provides a mobile and sometimes more flexible alternative to a traditional graving dock (a basin dug into the shore). It is particularly useful where water depth or space is limited, or when the dock needs to be relocated.
