Wind Energy

Nautec entered the onshore or land based renewable wind turbine market with our UHPC products in 2016. The products are being used in the structural connection between the gravity foundation and the turbine tower. In order to enter the renewable market, two of our UHPC products have gone through a rigorous test and certification program with European institutions. The certification covers both a U-certification, with is needed to enter the German market, and a CE certification according to EN 1504 for the rest of Europe.

We have furthermore documented the technical performance of our UHPC products through a large test program at MPA (Germany) which included creep and  fatigue testing as well as we have carried out large-scale trials at low (European conditions) and high temperature (Tropical conditions) to demonstrate the performance of our materials under severe weather conditions. As a result, we now are licensed with the world’s largest turbine manufacturer Vestas to supply UHPC for their turbine foundations.

The offshore renewable market is very similar to the offshore oil and gas market as the structures and installation principles are similar. We have been in the offshore installation market since our inception in 2011 and subject to our materials being approved we will enter this market. The approval process is expected to be completed later in the year.
