The demand for expected and unexpected maintenance work increases with every newly installed offshore wind turbine. With a potential of 5.000 sub-5MW blades which need to be exchanged in the coming years, a cost-effective solution is required.

By replacing the jack-up vessel with a floating solution with similar workability, significant costs and time can be saved. With the design of a dedicated turbine maintenance system, TWD together with Royal Wagenborg have come up with an innovative floating removal and installation method.

The vessel independent tool is equipped with a motion compensation system to mitigate relative motions during turbine approach and allows for a safe connection. Once connected, a smart blade handling cart can collect, transport and place blades and other heavy components of the nacelle.

At the moment we have successfully performed a technical feasibility study of the concept.

For more information, please visit Offshore Energy Exhibition at the Amsterdam RAI, stand 1.144. TWD is showcasing a scale model of the Blade Exchange Tool, and our colleagues will explain you more in detail.
