Offshore wind turbine with a floating platform

An offshore wind turbine system comprising a wind turbine in combination with a floating platform, the platform having a tower support that carries a tower of the wind turbine, the tower carrying a wind rotor;

• wherein the platform includes three buoyancy modules providing buoyancy to the platform when in water, the three buoyancy modules being arranged in a triangular configuration in corners of an isosceles triangle, equilateral triangle, the triangle having a base line and two equally long sides extending from two base corners at ends of the baseline and meeting at a top corner of the triangle, wherein the platform comprises a frame of braces rigidly connecting the buoyancy modules with the tower support in an approximate tetrahedral configuration, wherein
• the center axis of the tower is located
• on the baseline or at a distance from the baseline, the distance being in the range of 0-15% of the length L of the baseline;
• equidistant to the base corners or deviating from such equidistant configuration by less than 10% of L.
