To stabilise/dampen the vibrations in high towers, Betech has contributed to the development of a system of specially-designed oil-damped fenders that are suspended from the top of the tower.
Vario Gap Seal™ is an example of an innovative and effective way of sealing external joints between wall elements, where the outer gap between two cast iron panels can vary from 3 to 12 mm, sometimes within just a half a meter. The rough and uneven surface means that bonding and sealing with conventional sealing solutions is not possible.
Platform and panel assembly
PTFE (Sliding Pads®) anti-friction panels can be inserted between the inner platform and the steel holders on which the platform rests, to prevent wear and degradation of the steel platform’s structural frame.
Securing bolts in the panel joints prevent loose screw connections, which can be a particular challenge where connections are exposed to vibrations or offsets. Galvanic corrosion leads to destructive degradation of metal parts and is partly the result of the juxtaposition of steel and aluminium. Duboschweitzer® secure bolts can both prevent loose connections and seal against corrosion. The extra security contributes to prolonging the lifespan of the construction.
Monopile (Transition piece)
Grout Sealing is installed between the monopile and transition piece to prevent concrete leakage when assembling seabed wind turbines.
