Secure foundations for offshore wind farms
Hexabase ensures stability
Out there the winds are stronger and steadier which allows the efficient use of wind energy, making it a genuine alternative to conventional power stations
Installing wind turbines offshore is a demanding task. Not only do these huge, several hundred ton structures have to withstand being battered by strong winds and high waves, they also need to absorb the forces exerted by the turbines themselves. That calls for a secure base, which has to be installed under very difficult conditions. To date, no single design for the structures under the turbines – the so-called jackets – has come to the fore.
In collaboration with an engineering firm, thyssenkrupp Mannex is currently developing an extremely stable and efficient jacket foundation called Hexabase. As far as possible, the structures use standardized elements and are produced by automated processes for optimum efficiency.
Key to Hexabase is the use of wide hot strip in thicknesses of up to 25.4 millimeters for the majority of the tubular elements. This material is significantly easier to process into structural tubes than the quarto plate mainly used to date. As the welded tubes are all of the same diameter and the nodes are also of standardized design, the tubes and nodes can be joined by welding robots in fully automated processes. As well as saving time and money, computer-controlled welding also guarantees consistent weld quality.
