The invention relates to methods for installing a wind turbine. A method may comprise the steps of establishing a substructure, said substructure comprising at least one pipe (1) extending upwards and said at least one pipe (1) being part of a primary structure of the substructure, establishing a support of a secondary structure (5) on the at least one pile (1), mounting of fittings to the secondary structure (5), said mounting of the fittings to the secondary structure (5) preferably being established by welding or bolting, and not mounting fittings to at least one of the at least one pile (1) being part of the primary structure. A method may alternatively comprise the steps of mounting a wind turbine tower to the at least one pile (1) being part of the primary structure, and the secondary structure (5) constituting an intermediate structure (5,11) between the at least one pile (1) and the wind turbine tower (7). Even in the alternative, a method may comprise the steps of mounting of the secondary structure (5) to at least one intermediate tubular section (11) being part of the primary structure and mounting the wind turbine tower (7) to the at least one intermediate tubular section (11). |
