Technology

CLS Wind has developed several methods for wind turbine self-erection, including an elevator system for hoisting both wind turbine sections and a nacelle along a tower, with the nacelle pivoting at the top of a tower, which is patent protected on a worldwide basis.

This system design is applicable for both onshore and offshore wind turbines and will allow for concurrent installations, since it can be performed utilizing small cranes, which are commonly available; there is no need for large, high capacity cranes and/or heavy duty crane barges.

In addition, when utilized onshore, the installation site footprint will be much smaller than when using current methods, providing savings to the owners and reducing the environmental impact on the site.
