A device and method is disclosed for installing or dismounting turbine blades on an offshore wind turbine. The device includes a support structure (1) adapted to be installed on the deck of an installation vessel. The support structure holds an installation frame releasably hinged in a hinge structure (4). A turbine blade (7) to be installed is locked into the installation frame (2) by clamping arms (3). Then, the installation frame (2) may be raised in a vertical position and lifted until the blade (7) is brought into close proximity of the hub to which it is secured with bolts and nuts. The position of the installation frame (2) is controlled with a system of winches and steering wires. |
