Offshore wind farms to test business in deep water

Advocates of floating offshore wind platforms say they are cheaper to run and install, less disruptive to sea life, and have greater output than near-shore alternatives.

As wind turbines become increasingly familiar sights along shorelines, developers of offshore floating platforms, which harness the powerful winds further out to sea, are seeking to establish their technologies as a major viable source of clean energy. Bottom-fixed offshore wind turbines – with foundations in the seabed – face depth constraints and can only be … Read more
