A method for erecting and/or dismantling a tower, in particular a tower of a wind power installation, comprises providing a climbing crane, erecting the tower by hoisting and fastening tower segments and/or dismantling the tower by detaching and lowering tower segments, implementing, preferably temporary, securing measures for securing the tower in the state of assembly, in particular in the case of expected wind loads on the tower, which comprises taking into consideration the climbing crane, in particular its weight, in implementing the securing measures.

A method for decommissioning a wind turbine blade includes separating a root section of a turbine blade from a tip section of a turbine blade, and laterally cutting the tip section of the turbine blade into a plurality of separate tip subsections. Each tip subsection is cut along its length, flattened, deposited into a compacting and bundling apparatus, and compressed. The compressed tip subsections are bundled in the compacting and bundling apparatus with banding material to form a bundle. The bundle is removed from the compacting and bunding apparatus and loaded onto a transportation vehicle. A compacting and bundling apparatus includes a base having four base members that form a rigid base structure, a plurality of vertical posts secured to the base structure, and two cross members from a first side of the base to an opposing second side of the base.

Provided is a dismantling method of a tower-type wind power generation system in which scaffolding is not required around a tower body. After climbing on a work bench set outside an outer wall of a tower body and removing a lower end part of an upward-tapering part in an upper end part of the tower body over the entire periphery of the tower body, the tower body is removed from an uppermost part of a cylindrical part of the tower body below the upward-tapering part to dismantle the tower body from the top. The remaining upward-tapering part of the tower body is supported by a jack provided in an inner column while being lowered, along with the dismantling, into an internal cavity of the cylindrical part of the tower body and is placed on a placement protrusion provided on an inner wall of the tower body.

A method of dismounting or mounting a rotor blade of a wind turbine involves: supporting a rotor blade of a wind turbine with a ground-based lift system at a tip-side position on the rotor blade in relation to a center of gravity of the rotor blade, and supporting the rotor blade with a nacelle-mounted lift system at a hub-side position on the rotor blade in relation to the center of gravity of the rotor blade, so that the rotor blade is supported by the ground-based lift system and the nacelle-mounted lift system in a substantially non-vertical orientation with respect to the ground; and, then separating the rotor blade from or connecting the rotor blade to a rotor hub of the wind turbine.
