    Abstract: A load carrying structure (3) for a multirotor wind turbine (1) is disclosed. The load carrying structure (3) comprises a first load carrying arrangement (4) and a second load carrying arrangement (4), and each load carrying arrangement (4) comprises a primary structure (9) and at least two secondary structures (10), the secondary structures (10) extending on opposing sides of the primary structure (9) between an energy generating unit (5) carried by the load carrying arrangement (4) and an attachment point at a tower structure (2). Gravity acting on the energy generating units (5) causes push in the primary structures (9) and pull in the secondary structures (10), thereby causing preload of the secondary structures (10). The load carrying structure (3) is capable of handling thrust loads.

    Abstract: A wind turbine (10) supported by a plurality of cables (20). The wind turbine (10) includes a tower (12) fixed at one end to a foundation (16) and including at least two tower sections (12a, 12b, 12c), including an upper section and a lower section. Each of the upper and lower sections includes an inwardly directed flange (82, 90) having a plurality of through-bores (84, 92). The inwardly directed flange (90) of the lower section further includes a plurality of second bores (104) spaced apart from the plurality of through-bores (92). An interface module (18, 120) is secured between the upper and lower section and includes a ring (62) from which one or more cars (50, 204) extend outwardly, each ear (50, 204) being configured to be coupled to one of the plurality of cables (20). The ring (62) includes a plurality of through-bores (72) that align with the through-bores (84, 92) in the inwardly directed flanges (82, 90) of each of the upper and lower tower sections and a plurality of additional bores (96) that align with the plurality of second bores (104) in the inwardly directed flange (90) of the lower section. A method of installing a wind turbine (10) having a cabled tower (12) is also disclosed.
