A method for inserting a plurality of tendons (26) into a tower (14) comprises the steps: provision of the tendons (26) in a storage area (32), picking up one of the tendons (26) by means of the pick-up device (34) of a crane (38), raising the tendon (26) to the top of the tower (14), insertion of the tendon (26) into the tower (14) from above, lowering the pick-up device (34) to the storage area (32). According to the present invention, after being raised to the top of the tower (14) and prior to the insertion of the tendon (26) into the tower, the tendons (26) are brought into unwinding engagement with an unwinding device (30), which is permanently arranged there for at least the duration of the insertion procedure, and the pick-up device (34) is already again lowered to the storage area (32) while the tendon (26) just raised to the top of the tower is inserted into the tower (14) from above by means of the unwinding device (30).

TELWIND unites a strong complimentary team of renowned European companies and research institutions, which join forces to develop a revolutionary integrated floating offshore system. The concept, which has already undergone trial tank testing with overly positive results, shall enable a radical cost reduction both in terms of material usage and required means and operations. The system has been conceived in a holistic approach to the overall substructure, tower and turbine, generating ground breaking synergies between the integrated elements to specifically address the particular requirements of offshore wind, focusing in the capacity for low-cost industrialization in the inshore construction and offshore installation processes. The Telwind concept integrates a novel floating substructure and a pioneer self-erecting telescopic tower. The former provides all the performance advantages of a spar-buoy substructure while allowing for qualitatively lower material usage, the latter enables a full onshore preassembly of the overall system and a highly beneficial reduction of offshore works and auxiliary means. Together they overcome the limitations imposed by the available inshore infrastructure and offshore heavylift vessels, and thus generate a fully scalable system, perfectly fitted for the effective integration of the next generation of extremely large (10MW\) offshore wind turbines which are key to enhance the reduction of the Levelised Cost of Energy (LCOE). The system will also profit from the proven structural efficiency and economy of precast concrete, a material particularly well suited for low-cost industrialized production of repetitive units. Robust, reliable and virtually maintenance-free marine constructions result, reducing OPEX costs, greatly increasing durability and fatigue tolerance, and setting the ground for extended service life of the infrastructure, which could further magnify the systems capacity for drastic reduction of the LCOE.
