1. A floating wind power platform for offshore power production, comprising:
a floating unit, wherein the floating unit comprises a first, a second, and a third interconnected semisubmersible column each being arranged in a respective corner of the floating unit, wherein the floating wind power platform further comprising a first and a second wind turbine, arranged to the first and the second semisubmersible columns, respectively, via a first and a second tower respectively,
wherein a tension leg device is arranged solely to the third semisubmersible column, wherein the tension leg device is adapted to be anchored to a seabed by an anchoring device, wherein the third semisubmersible column provides an upwardly directed excess buoyancy force adapted to create a tension force in the tension leg device, the upwardly directed excess buoyancy force is held by the tension leg device preventing the floating wind power platform from rising; and
wherein the floating wind power platform is further adapted to weather vane in relation to a wind direction, wherein a turret is arranged to the third semisubmersible column.
