A buoyant vessel for storing offshore oil and gas production having a ballast compartment for stability which can be raised and lowered relative to the vessel. The ballast compartment is in a lowered position when the vessel is in its offshore location, and it is in a raised position flush with the hull of the vessel when the vessel is being moved to and from its offshore position. This vessel is used in cooperation with wells completed on the floor of a body of water with flexible flow lines and hydraulic lines attached from the vessel to the wells by way of a float located on the water surface. The production is processed on the vessel and stored therein with ballast and stored fluids manipulated to provide appropriate buoyancy for the vessel.
