Abstract

A method for erecting a multirotor wind turbine (10) is disclosed. A carrier structure (1, 1a, 1b) is arranged circumferentially with respect to a tower structure (2) and hoisted to an upper part of the tower structure (2), using a hoisting arrangement, such as a wire winch arrangement (3, 4, 8). Furthermore, energy generating units (5) may be hoisted to the carrier structure (1, 1a, 1b) using the hoisting arrangement (3, 4, 8). A similar method for dismantling a multirotor wind turbine (10) is also disclosed. The multirotor wind turbine (10) can be erected or dismantled without the need for an external crane.

Claims23

Dependent claims

A method for erecting a multirotor wind turbine, the wind turbine comprising a tower structure, at least two energy generating units, each energy generating unit comprising a nacelle and a hub carrying a set of wind turbine blades, and at least one carrier structure, each carrier structure comprises a ring and one or more arms extending away from the ring, each carrier structure being arranged to carry one or more of the at least two energy generating units at an end of the one or more arms, the method comprising:

arranging the ring of the carrier structure circumferentially with respect to and adjacent to the tower structure in such a manner that the one or more arms extend away from the tower structure, at a lower part of the tower structure,
hoisting the carrier structure to an upper part of the tower structure, using a hoisting arrangement, and
securing the carrier structure to the tower structure,
wherein the carrier structure supports the at least two energy generating units when the at least two energy generating units are generating electrical energy.

1 more element

A method for erecting a multirotor wind turbine, the wind turbine comprising a tower structure, at least two energy generating units, each energy generating unit comprising a nacelle and a hub carrying a set of wind turbine blades, and at least one carrier structure, each carrier structure being arranged to carry one or more of the at least two energy generating units, the method comprising:

arranging the carrier structure circumferentially with respect to the tower structure, at a lower part of the tower structure,
hoisting the carrier structure to an upper part of the tower structure, using a hoisting arrangement,
securing the carrier structure to the tower structure,
hoisting the at least two energy generating units to the carrier structure, using the hoisting arrangement, and
securing the at least two energy generating units to the carrier structure,
wherein the carrier structure supports the at least two energy generating units when the at least two energy generating units are generating electrical energy.

3 more elements

A method for at least partly dismantling a multirotor wind turbine, the wind turbine comprising a tower structure, at least two energy generating units, each energy generating unit comprising a nacelle and a hub carrying a set of wind turbine blades, and at least one carrier structure, each carrier structure being arranged to carry one or more of the at least two energy generating units, and the carrier structure being arranged circumferentially with respect to the tower structure at an upper part of the tower structure, the method comprising:

lowering one or more of the at least two energy generating units to the ground, using a hoisting arrangement,
detaching the carrier structure from the tower structure, and
lowering the carrier structure to a lower part of the tower structure, using a hoisting arrangement.
