Floating Offshore Wind Turbine Engineering Services

Offshore Wind has already been identified as one of the main option to decarbonise the Global Energy Production & Consumption. Furthermore, the Floating Wind sector appears to hold the highest potential to limit the societal and environmental impacts and improve the Levelized Cost of Energy (LCOE).
Nevertheless, going offshore and into deep-water and more challenging areas require improved engineering, updated methodologies and more performant products. D-ICE is committed to make the Floating Wind a competitive and safe energy source. Hence, we are developping an innovative and fully dedicated controller, BLADiCS. High-performances controller has already been recognized as a real key for the FOWT technology development.
Finally we offer our engineering skills at each phase of your project.
