Siemens Gamesa to install recyclable blade this summer at kaskasi

Siemens Gamesa has announced that this summer it is installing the world's first recyclable blade at RWE's
Kaskasi wind farm in German waters. The 81-meter long blades are designed to enable the recycling of the composite parts into new products at the end of their lifecycle.

For its recyclable blade, Siemens Gamesa is using a new resin type, with a chemical structure that makes it possible to separate the resin from other components. The process protects the properties of the materials and so allows them to be reused in new casting applications, for example in the automotive industry, or in consumer goods like flight cases and flatscreen casings.

The 342 MW
Kaskasi wind project is located 35 kilometres north of the island of Heligoland, Germany. Installation of the wind turbines is scheduled to start this summer. The project is planned to be fully commissioned by the end of 2022. Once fully operational, the project is expected to supply the equivalent of 400,000 households a year with green energy.

RWE has plans to trial other innovations at its
Kaskasi wind farm. RWE installing, for the first time ever, special collars around three monopile foundations. The steel collars are designed based on a RWE patent and will be installed at seabed level. The space between collar and monopile foundation will be filled with grout material to create a stable connection. RWE will carry out accompanying tests to verify that the collar improves structural behaviour, compared to standard monopiles.

Kaskasi is he first commercial offshore wind farm in the world to using a new installation method for driving the wind turbine foundations into the seabed to their target penetration depth. In comparison to conventional hammering techniques the innovative vibro pile driving method will speed up the process of installing the foundations, has a gentler impact on the structure while producing far less noise, and reduces impacts on the maritime environment, according to RWE.
