The present invention relates to a foundation device for an offshore wind turbine tower. The device comprises a first body (1), a support body (3) attached to the first body (1), a second body (2) and a plurality of legs (4) attached to the second body (2). The support body (3) has a cylindrical interior and is configured to provide support for and connection of a wind turbine tower (10). The first body (1) comprises a central portion (5) connected to the support body (3) and a plurality of hollow arms (6), connected with the central portion (5). Each hollow arm (6) comprises a through-hole (7) configured to allow a leg (4) to pass through the through-hole. The first body (1) has a volume and a weight configured to provide, when empty, a buoyancy of at least 20% of the weight of the entire device, the weight of the first body (1) being less than 8% of the weight of the entire device. The legs (4) and/or the first body (1) have a locking system configured to lock the relative position between the legs and the first body.
