NOVELTY - The platform has floating or semi-submersible peripheral units (2a-2d) connected to adjacent peripheral units by a coupling arrangement (6), which is an elongated object variable in length arranged to allow each floating peripheral unit to move in relation to the adjacent peripheral units along direction parallel to elongation direction of the coupling arrangement. Length of the coupling arrangement is to be adjusted by a length adjusting arrangement adapted to shorten the coupling arrangement and to pull two adjacent floating peripheral units toward each other.    USE - Floating platform for an energy producing plant (claimed).    ADVANTAGE - The platform is durable, cost effective and easy to manufacture, transport and assemble at a location far away from shore. The peripheral units can be arranged in a pattern creating hexagon shape with a center node, while using the elongated object for creating a natural optimized balanced structure. The platform is designed such that assembly process of the separate floating units far out from shore is simplified when the coupling arrangement is adjustable in length to re-tension the coupling arrangements after some time, thus increasing life of the platform. The platform can be firmly anchored at bottom by an anchoring system that is attached to a central unit for enabling the entire platform to rotate and automatically adjust in line with wind or water current direction, so that energy producing systems i.e. wind power generators, are placed in an optimum position for energy extraction. The wind power generators can be placed on semi-submersible nodes of the platform when the wind power generators are used, thus enabling access to a generator housing through a hollow interior of the nodes and connection units. The floating units can be easily towed to a predetermined location out in the ocean and assembled on site.    DETAILED DESCRIPTION - The coupling arrangement is a mechanical arrangement such as flexible wire, cord, cable and rope. The length adjusting arrangement is a winch. An INDEPENDENT CLAIM is also included for an energy producing plant.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a floating platform of an energy producing plant.
