1. A semi-submersible platform for positioning in a body of water and for production of electrical energy from wind energy, the semi-submersible platform comprising:
a submersible underwater hull made up of at least a first and second elongated pontoon;
at least three columns supported on and interconnected by the submersible underwater hull and protruding above the surface of the body of water when the semi-submersible platform is positioned in the body of water,
wherein at least three of said columns form stabilizing buoyant columns;
at least one wind energy harvesting device arranged on a supporting structure arranged at an upper end of one of the at least three columns,
wherein
said first elongated pontoon is within two outer parts supporting and interconnecting to a lower end of two of the stabilizing columns,
said second elongated pontoon is perpendicular to and interconnecting to said first elongated pontoon at mid-length of said first pontoon,
said second elongated pontoon is supporting and interconnecting to a lower end of a third stabilizing column at a third outer part opposite to the end interconnecting to said first elongated pontoon,
said first and second elongated pontoons are interconnected mid-length of said first elongated pontoon so that the first and second elongated pontoons form a structure resembling the letter “T” in a horizontal plane, wherein the T-shaped structure has three ends, and
wherein at least one of said at least three stabilizing buoyant columns is arranged at each of the three ends of the T-shaped structure.
