A telescopic deployment system for the DDWTG, a novel design for a customized deployment vessel, and a round-the-clock 24/7 construction schedule result in a build-out of one complete spar buoy in just 15 days and its deployment in two days.

This new SB will be the first to have a double wall hull and use innovative new concrete materials in a design mix that will ensure a minimum 100-year life in any sea state, providing a foundation substructure good for three generations of DDWTG. The key is a new large-scale spar buoy (SB) structural design, which is scalable and allows for only one construction formwork design to support and produce all the 10-MW to 20-MW floating foundation requirements. A new innovative floating foundation system with a unique deployment method will substantially reduce the levelized cost of energy of the DDWTG. Developers of clean energy are ready to deploy large, efficient 10-MW to 20-MW direct drive wind turbine generators (DDWTG) in far offshore, deep-water wind farms.
