UHPC Installation of Offshore Wind Turbine Foundations
Nautec has been involved in more than 60 projects globally where offshore mixing, pumping and injection of UHPC materials into structures situated in both shallow and deep water has been the integral component of the project. This extensive marine grouting experience in conjunction with outstanding in-house knowledge of the design and manufacture of UHPC materials, is what we Nautec brings to the offshore wind turbine foundation market.
We are currently operating seven offshore spreads with the flexibility of being fed by either silo or bulk bags. Depending on the feeding system, material, delivery distance and configuration of receiving structure, the spread rates vary from 4 to 15 m3 but can be increased by adding additional mixing and pumping modules.
The spreads operate with batch mixing systems as they guarantee high quality and consistency of the grout output yet they are still able to deliver high rates for high volume projects.
