SLPE Completes Concept and Detailed Design for SeaMade Offshore Wind Farm

27 July 2021
SeaMade Seastar Mermaid Offshore Substation

We proudly look back on the part we played in the development of the SeaMade offshore wind farm, currently the largest operational wind farm in the Belgian North Sea with a combined output of 487 MW.

SLPE delivered the concept design and, subsequently, the detailed design of steel monopile foundations for two offshore substations, for the Seastar and Mermaid concession zones respectively.


The Seastar and Mermaid monopiles are installed in a water depth of circa 35 metres, each supporting a topside of approximately 1,100 tonnes.

SLPE carried out integrated geotechnical-structural engineering, including the design of the monopiles, transition pieces, j-tube cages, secondary steel structures as well as corrosion protection – a complete support structure solution with due consideration to the whole project lifecycle.

Please get in touch with us if you would like to know more about our experience and innovation initiatives in developing support structures and foundations for offshore wind substations. We would be more than happy to hear from you.
