A wind power arrangement ("A") related to a body of water ("V") for creating prerequisites from a predominant wind force for generating electric power, comprising: a) individual but connected pontoon units (1, 2, 3) that may float in the body of water ("V"), b) a plurality of, at least two, adjacent to each other oriented and coordinated turbines, namely wind-driven propellers (4b, 4, 4a, 4c), c) a mooring system ("M") solidly anchored to a restricted bottom area of said body of water ("V"), d) a generator unit ("G") which may be driven by the rotating motion of a turbine for generating said electric power, and e) a cable section connected on the one hand to said generator unit ("G") and on the other hand to a land based distribution network distributing generated electric power, wherein said pontoon units comprise at least two essentially vertical posts (1, 2) which may float per se, for forming a frame portion, and at least one upright stabilizing the position of the frame portion in the body of water, wherein said two posts (1, 2) are adapted to support a horizontally oriented beam structure which is flexurally rigid in itself, said beam structure being adapted and dimensioned to support said turbines (4b, 4, 4a, 4c), wherein each one of said two posts (1, 2) together with said upright is dimensioned and/or adapted such that with their lower portions (1, 2a, 3a) immersed in said body of water ("V") they keep the frame portion floating over the water surface ("Va"), wherein said upright is arranged at a distance from a plane ("P") containing said frame portion and said two posts (1, 2), and wherein said upright is connected to said frame portion via bar-shaped means (10, 10a) dimensioned for taking up a compressive force and extending between said upright and each one of the two posts, a first post and a second post, and wherein said upright is adapted to be attached to and cooperate with said mooring system ("M"), characterized in that the wind power arrangement ("A") further comprises: rotatable propeller blades (4b1, 4b2) allotted to said turbines and rotatable by the wind force which are pitchably disposed around a central line (4b4) or ascent profile of the propeller blade (4b1, 4b2) with regard to a hub (4b3), and a first means in the form of a control unit adapted to control the rotational movement of the propeller blade (4b1, 4b2) with regard to the hub (4b3) during its rotation through an arrangement, wherein said first means and its associated arrangement are further adapted to assign different positions of rotation, i.e. different pitch angles, to the propeller blade (4b1, 4b2) with regard to the hub (4b3) during one revolution which cause the wind power arrangement ("A") to turn so that it can take the best angle with regard to a main wind direction. a) individual but connected pontoon units (1, 2, 3) that may float in the body of water ("V"), b) a plurality of, at least two, adjacent to each other oriented and coordinated turbines, namely wind-driven propellers (4b, 4, 4a, 4c), c) a mooring system ("M") solidly anchored to a restricted bottom area of said body of water ("V"), d) a generator unit ("G") which may be driven by the rotating motion of a turbine for generating said electric power, and e) a cable section connected on the one hand to said generator unit ("G") and on the other hand to a land based distribution network distributing generated electric power, rotatable propeller blades (4b1, 4b2) allotted to said turbines and rotatable by the wind force which are pitchably disposed around a central line (4b4) or ascent profile of the propeller blade (4b1, 4b2) with regard to a hub (4b3), and a first means in the form of a control unit adapted to control the rotational movement of the propeller blade (4b1, 4b2) with regard to the hub (4b3) during its rotation through an arrangement, wherein said first means and its associated arrangement are further adapted to assign different positions of rotation, i.e. different pitch angles, to the propeller blade (4b1, 4b2) with regard to the hub (4b3) during one revolution which cause the wind power arrangement ("A") to turn so that it can take the best angle with regard to a main wind direction.
