TAUT MOORING FLOATING BODY SYSTEM, SUPPORT SYSTEM, AND TOWING METHOD AND INSTALLING METHOD OF FLOATING BODY USING SUPPORT SYSTEM

PROBLEM TO BE SOLVED: To provide a taut mooring floating body system for reducing an immersed part and an immersed area of a floating body for supporting an upper structure, and avoiding underwater work for mounting a taut mooring rope, adjusting tension, maintenance and inspection or the like while maintaining an upper mooring part of the taut mooring rope on a water surface. SOLUTION: In the taut mooring floating body system 1, a floating body 12 for supporting the weight of an upper structure 11 on the water surface by buoyancy is configured to have a central columnar body 12a, a submerged buoyancy body 12b on a lower portion thereof, a superaqueous connecting body 12c extending from the central columnar body 12a in the circumferential direction, and a superaqueous mooring part 12d provided on an end of the superaqueous connecting body 12c and fixed to an upper end of a taut mooring rope 13, and is also configured such that all or more than half of a surface area of the superaqueous connecting body 12c is above the water surface in static water and the superaqueous mooring part 12d is above the water surface in static water.
