A buoyant submersible structure floating above the sea floor includes a support portion to support a load, and a gas-filled tank. The tank has an opening, and a connected tube. The tube is partially filled with seawater defining a water-gas interface at a first level. In operation, the structure is fully submerged below the water surface to a first depth. The second chamber is partially filled with seawater defining a water-gas interface at a first position inside the second chamber. Then, the buoyancy structure is moved to a second, greater depth. Water enters the second chamber to raise the water-gas interface to a second, higher level and without entering the first chamber. Subsequently, the buoyancy of the structure is adjusted to tension the cable, a support structure to support a load is attached to the structure, and then the buoyancy of the structure is readjusted. |
