SeaTwirl has unveiled a new vertical-axis offshore wind turbine with two blades rather than the three it used in earlier models
“The main difference with this new, two-blade design is the turbine essentially becomes a two-dimensional structure that can be assembled flat on the ground without large cranes,” said SeaTwirl. “This also significantly reduce weight and maintenance requirements.”
SeaTwirl’s vertical-axis wind turbines use a rotating SPAR foundation and do not require pitch or yaw systems. They have a low centre of gravity, standardised drivetrain components and are easily accessed for maintenance.
SeaTwirl chief executive Johann Sandberg said, “We are excited to finally bring our two-blade turbine to the market and showcase its benefits.
“Our ambition has always been to design away challenges to building out floating wind technology. This design enables ‘flat-pack assembly’ suitable for smaller yards.”
The Swedish company has been developing floating wind turbines intended for deepwater deployment for some time, focusing on turbines that can be deployed wherever needed, that can be installed and maintained with significantly less infrastructure than conventional turbines.
