Abstract

A buoyancy device (1) is attached to a structure to be floated or sunk. The buoyancy device (1) comprises a restriction device such as a rigid tube (3) and an inflatable member (5, 15) located within the restriction device (3). The restriction device (3) restricts inflation of the inflatable member (5, 15). The inflatable member (5, 15) comprises a first flexible portion (5) and may be in the form of a tube (5) and a second flexible portion (15) which may be in the form of a diaphragm (15). The tube (5) is coupled to the restriction device (3) and the diaphragm (15) is coupled to the tube (5).
