A method of transporting and storing a wind turbine blade ( 1 ) including a blade root ( 10 ) and a blade tip ( 4 ), where the wind turbine blade curves in the unloaded state in such a manner that the blade ( 1 ) presents a substantially concave face ( 30 ) and a substantially convex face ( 12 ), and such that said blade tip ( 4 ) is spaced apart from the longitudinal central axis ( 28 ) of said blade root ( 10 ). By the method, the wind turbine blade ( 1 ) is prestressed by means of prestressing means ( 2, 5, 6, 9, 13, 16, 17, 21, 22, 23, 24, 25, 26, 33 ) at a distance from the blade root ( 10 ) in such a manner that the blade tip ( 4 ) is brought closer to the longitudinal central axis ( 28 ) of the blade root ( 10 ). The invention also relates to a curved wind turbine blade ( 1 ) being provided with inner ballast tanks ( 21 ) at a distance from the blade root ( 10 ), whereby the blade is prestressed by filling said ballast tanks in such a manner that the blade tip ( 4 ) may be brought closer to the longitudinal central axis ( 28 ) of the blade root ( 10 ). The invention further relates to an apparatus including prestressing means for loading a curved blade at a distance from the blade root ( 10 ) in such a manner that the blade tip ( 4 ) is brought closer to the longitudinal central axis ( 28 ) of the blade root ( 10 ).
