A method for drilling with a buoyant structure having a hull, a planar keel defining a lower hull diameter, a lower cylindrical portion connected to the planar keel, a lower frustoconical portion disposed above the lower cylindrical portion with inwardly-sloping wall at a first angle, an upper frustoconical portion directly connected to the lower frustoconical portion. The method uses a ballasted chambered buoyant storage ring which is either dockside and connected to the buoyant structure for drilling at a subsea location, or the ballasted chambered buoyant storage ring is preinstalled at a subsea location and then the buoyant structure is mounted to the ballasted chambered buoyant storage ring at sea.
