A ring wing floating platform comprising: a floatation body, where the top part thereof is elevated above seawater level; a ring wing surrounding the periphery of the bottom part of the floatation body, where the bottom part of the ring wing is in flush with the bottom part of the floatation body, annular gaps are provided along the radial direction, and the ring wing and the floatation body form an integral structure via multiple connection structures distributed in the radial direction; a positioning system arranged at the bottom part of the floatation body; and, a topside facility arranged on top of the floatation body. The ring wing floatation platform is applicable for oilfield and gas field exploration, development, and production in deepwater and adverse sea conditions, and is a system that is environmentally friendly, safe and reliable, flexible to use, and convenient to transport. All construction and commissioning works for the entire platform can be completed in a shipyard, thus greatly conserving facility construction costs, oil and gas field production operating costs, and disposal costs. |
