Cirrus Project Could Combine Floating and Fixed-Bottom Offshore Wind The Hexicon-Mainstream Renewable Power partnership also plans to potentially install a combination of fixed-bottom and floating wind turbines.
“Cirrus is planned to be an offshore wind farm with bottom-fixed turbines, but Freja Offshore will also investigate the potential use of floating wind turbines for the deepest sections. The offshore wind farm will however still be beyond the horizon and just barely visible during clear weather conditions as it will be situated 50 kilometers off the coastline” , the joint venture stated in a press release on 22 June.
According to the consultation document, the floating option could not only be chosen for some of the wind turbines but is also being considered as one of the possibilities for an offshore substation.
Freja Offshore also noted that the wind farm site had been “meticulously designed” to minimise any disturbances and seamlessly coexist with other vital societal concerns, particularly addressing the needs of other users of the sea such as the Swedish Armed Forces.
The project site is located in the southern Baltic Sea, some 50 kilometres south of Karlskrona and 50 kilometres south of Öland, in Sweden’s exclusive economic zone.
The application, now submitted to the Swedish Ministry of Climate and Business, is related to the construction and operation of the Cirrus offshore wind farm in accordance with the Law on Sweden’s Economic Zone (SEZ) and the establishment of an internal cable network under the Continental Shelf Act.
The project’s proximity to Natura 2000 areas may mean that a special Natura 2000 assessment would be needed, so the joint venture also included an assessment for this permit in the consultation document, as well.
Cirrus is not the first project Hexicon and Mainstream Renewable Power plan to build in Sweden.
In April, the joint venture submitted a planning application under the Swedish Economic Zone Act (SEZ) for another, 2.5 GW offshore wind project. Located in the North Sea and named Mareld, this project is planned to comprise floating wind turbines.
