The present invention addresses the problem of providing a tension-mooring cable for a tension-moored floating body, with which it is possible to, without adjusting the lengths of the tension-mooring cables in each mooring cable bundle that moors and supports the tension-moored floating body, equalize tension generated in the tension-mooring cables and prevent occurrence of resonance with the frequency of waves on the ocean. The problem is solved by a mooring cable that is for a tension-moored floating body, and that links a connection part 5b formed on the tension-moored floating body and a sea bottom-mooring part 9 fixed to a sea bottom 103. The tension-mooring cable is configured such that tension is generated in a tension-mooring cable 7 due to buoyancy generated in a tension-moored floating body 5 when the tension-mooring cable 7 is linked to the tension-moored floating body 5, and the tension-moored floating body 5 can be held in a tension-moored state. The tension-mooring cable 7 is configured such that a low rigidity mooring cable 7b, having a low extensional rigidity which is the product of the modulus of longitudinal elasticity and the cross-sectional area of a cable material, is linked to a high rigidity mooring cable 7a having a higher extensional rigidity than that of the low rigidity mooring cable 7b, by a linking tool.

Vertical-axis wind turbines (VAWTs) have inherent advantages over horizontal-axis wind turbines (HAWTs) resulting from the low center of gravity primarily caused by the low height of the drivetrain relative to the rotor. The low center of gravity is one of the main drivers for development of VAWTs for floating offshore wind energy generation, where the reduced center of gravity has positive system benefits by reducing the demands placed on the floating platform and its associated mass and cost. This advantage for VAWTs can be further enhanced by lowering the elevation of the drivetrain by housing it within the platform column.
