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).
