Abstract
A lift bag for moving an object underwater includes a lift bag body and a buoyancy regulator device within an internal cavity of the lift bag body. The buoyancy regulator device includes concentric regulator tubes. Each regulator tube includes a regulator tube opening and the regulator tube openings may be aligned to define a regulator tube aperture. The regulator tube aperture is in fluid communication with a lift bag slot formed in the lift bag body. A constant buoyancy for the lift bag is determined by adjusting the position of the regulator tube aperture by moving the inner and outer regulator tubes with respect to each other.
