Tank tests of a modular floating wind foundation concept being developed by modern wind pioneer Henrik Stiesdal to gear up industrialisation of the fast-emerging sector have kicked off at the Technical University of Denmark (DTU) R&D facility in Lyngby.

The design, a tetrahedral steel structure constructed from components derived from tower technology, will be put through month-long trials using a 10MW turbine model with two different rotor configurations, and with semisubmersible and spar variants of the Stiesdal floater.
