Ring-wing floating platform

A ring-wing floating platform, comprising:

• a floating hull, wherein a top of the floating hull is above a sea surface and its geometry at a water plane is centrally symmetric;
• a ring-wing surrounding a perimeter of a bottom of the floating hull with a horizontal projection of concentric annular geometries, wherein the ring-wing is a segmented ring-wing, wherein one or more segments of the segmented ring-wing are one or more of:
• a fixed ring-wing segment, a tieback ring-wing segment, or a rotatable and foldable ring-wing segment;
• a positioning system located at the bottom of the floating hull;
• and
• a topsides located above the floating hull and connected to the floating hull by deck legs or installed directly on the top of the floating hull,
• wherein axes of the ring-wing and the floating hull are collinear, and their bottoms are in a same horizontal plane, wherein the ring-wing and the floating hull are connected together as a unitary structure by multiple connecting components with an annular gap in-between, and
• wherein multiple tieback ring-wing segments form a tieback ring-wing, wherein one or more fixed ring-wing segments and one or more tieback ring-wing segments form a partial tieback ring-wing, wherein the one or more fixed ring-wing segments and one or more rotatable and foldable ring-wing segments form a rotatable and foldable ring-wing.
