2-B Energy – Back To Two Blades

3-blade turbines have become the standard in present day wind energy development. The Dutch company 2-B Energy argues that for offshore, wind 2-blades could perhaps be a better design. First of all from a maintenance perspective: in case of a defect, nacelle and rotor can be lifted from the tower in one piece and brought to a maintenance location, onshore or nearby offshore. Furthermore the company claims to be able to realize lower production costs. A first 2-b wind turbine has meanwhile been installed in Eemshaven, in the North of the Netherlands, see video below. Installation rotor downwind and able to rotate freely around a vertical axis, ensuring automatic direction towards an orientation perpendicular to the wind flow. Dimension nacelle 17 m, large enough for a helicopter to be able to land on top of it. Gain: less material, easier maintenance. 2-B Energy is participating in the Methil offshore project off the coast of Scotland.

At [1:33] you can see the test-installation of the 2-B wind turbine in Eemshaven. Visually it is not a very attractive installation, but it is intended for offshore operation anyway.
