A British/French consortium led by engineering and environmental consultant Gifford has come up with a deep-water wind-turbine foundation design suitable for deeper seawater conditions (30-60m). Just recently, it was shortlisted in a multi-million pound Carbon Trust competition for its structural design, durability, maintainability, turbine accessibility, and relatively lower manufacturing, transport and installation costs. The competition proposed to devise newer installations of thousands of wind turbines around Britain’s coast.

The concrete foundation for offshore wind turbines was developed in conjunction with Freyssinet and BMT Group. The unique system design weighing over 3,000 tons uses gravity as the primary means of stability in water depths of 20m to 45m. It has a large base with submersible barges that ensures it doesn’t ask for heavy crane barges and offshore jack-up platforms. The Department for Business Enterprise and Regulatory Reform and E.ON funded the consortium to continue its studies on the design with Hunter Associates, Bierrum International, University of Nottingham, E.ON and DONG Energy.
