Abstract: A floating multi-turbine wind power platform for offshore power production, wherein the platform has a substantially elongated shape with an extension direction and being attached to at least two mooring points for securing the platform at its operation site in an original position in relation to the mooring points. The platform includes a device for rotation of the platform (MR1) around an essentially vertical first axis (z1) and further includes at least two wind turbines arranged substantially in a straight line corresponding to the extension direction of the platform and the at least two wind turbines each includes a structural support component and a rotor component. The rotor component is attached to a nacelle which is arranged to rotate using a device for rotation of the nacelle (MR2).

Abstract: The invention relates to a floating platform (1) comprising at least three floating or semi-submersible peripheral units (2; 2a, 2b, 2c, 2d) arranged connected to a floating or semi-submersible central unit (3) by at least one in a substantially radial direction arranged rigid and elongated radial connection member (5). The floating or semi-submersible peripheral units (2; 2a, 2b, 2c, 2d) are connected to the adjacent peripheral units (2; 2a, 2b, 2c, 2d) by a coupling arrangement (6) which is an elongated object variable in length arranged to allow each floating peripheral unit (2; 2a, 2b, 2c, 2d) to move in relation to the adjacent peripheral unit (2; 2a, 2b, 2c, 2d) at least in a direction substantially parallel to the elongation direction of the coupling arrangement (6).

Abstract: Floating energy producing plant (1), comprising at least three wind generators (2) attached to a common floating unit which can be placed on water independent of placement and water depth. The unit comprises a frame work (F) constructed of pipes (4) connected in at least three attachment points having the shape of nodes (3, 5). The pipes (4) are sealed in their respective ends (4a, 4b) and forms separate floating parts adapted to be connected to the nodes (3, 5).
