Innogy has paved the way for the construction of its third German offshore wind energy farm with a final investment decision for the Kaskasi project.

The developer announced that the project build will start in the third quarter of 2021 and that it has signed main contracts worth a combined €500 million with suppliers including Siemens Gamesa, Bladt Industries and Seaway 7.

The 342 MW wind farm will be located 35 kilometres north of the island of Heligoland. Improved installation methods will be used during construction to reduce installation time and noise emissions, Innogy said.

Siemens Gamesa Renewable Energy will supply 38 of its SG 8.0-167 DD Flex offshore wind turbines for the project. Bladt Industries A/S has been contracted to fabricate, deliver and commission the offshore transformer substation as well as all monopile foundations.

Seaway 7 will be in charge of the installation work, using a so-called vibro pile driving method.

“Following our success in the German offshore auction in 2018, we have now taken the next important step in realising Kaskasi offshore wind farm,” said Sven Utermöhlen, Senior Vice President Renewables Operations Offshore at Innogy SE. “With Siemens Gamesa, Bladt Industries and Seaway 7 we have brought extremely experienced contractors and suppliers on board for all key components and their installation, which is expected to start next year.”
