ABSTRACT:
A buoy having a controllable buoyancy and being particularly adapted for subsea use. The buoy includes an upper buoyant chamber member mounted with a lower chamber member. The lower chamber member has a lower chamber formed in it for containing variable amounts of a fluid which is buoyant in water and for containing variable amounts of water. The lower chamber member additionally has an opening formed in its bottom to permit water to pass into and out of the lower chamber and fill the portion of the lower chamber which is not occupied by the buoyant fluid. A control assembly operably connected to the lower chamber regulates the amounts of buoyant fluid in the lower chamber so that the buoyancy of the buoy is controlled.
