Abstract: A plurality of wind turbine blades or blade portions have substantially the same size and outer geometrical shape, and corresponding plies of the blades or blade portions having the same position within the respective wind turbine blades or blade portions have different fibre orientation angles relative to a pitch axis of the respective wind turbine blade or blade portion. By changing the fibre orientation angles of the corresponding plies a bend-to-twist coupling of the blade or blade portions may be varied amongst the plurality of blades or blade portions. The blades may then be tailored according to their siting within or on a wind turbine park. A common mould shape may be used across the plurality of wind turbine blades or blade portions, together with a more streamlined blade design process.

Abstract: A method for constructing a floater for a floatable wind energy power plant includes providing a first pre-assembled part with at least one first connection arrangement, providing a second pre-assembled part with at least one second connection arrangement, arranging the at least one first connection arrangement of the first pre-assembled part proximate to the at least one second connection arrangement of the second pre-assembled part so as to form a connection site which includes at least a part of the at least one first connection arrangement and at least a part of the at least one second connection arrangement, sealingly arranging an enclosure about the connection site so as to seal the enclosure against an ingress of water, and connecting the first pre-assembled part and the second pre-assembled part at the connection site. Each of the first pre-assembled part and the second pre-assembled part are floatable.
