Floating Wind Could Trigger a Dramatic Redesign for Turbines

By [email protected] Siemens Gamesa last month trumpeted market-leading innovation in turbines installed at the world’s largest floating wind farm.

But at least one expert has claimed the 6-megawatt horizontal-axis wind turbine (HAWT) design deployed at Hywind is not groundbreaking enough to meet the industry’s future needs.

“Although I have done a lot of technical due-diligence work since 2010, I have never been entirely convinced that simply making HAWTs bigger and bigger is a way forward,” said geotechnical and engineering geology consultant Chris Golightly.

Instead, Golightly believes the industry should be moving to develop vertical-axis wind turbine (VAWT) designs for use with floating substructures. “VAWTs are
