The Norwegian Environment Agency has received notice from Swedish authorities about plans to establish Mareld, a proposed floating offshore wind farm to be developed by Swedish company Hexicon and located in the waters of Skagerrak off Sweden's eastern coast.

Mareld could come to feature a total of 230 floating wind turbines with tip heights of 350 meters. Moreover, the facility's zoning entails keeping within a maximum area of 499 square kilometers.

The offshore wind farm has a projected annual generation of 12 TWh.

"An advantage of floating foundations is that the facility can be placed in deeper waters and thus further from land. That means less disturbance to bird life and recreation and has significantly less visual impact," Hexicon writes in its application:

"Another advantage with wind turbines upon floating foundations is that construction work on the seabed will be considerably less extensive and result in a reduced dispersal of sediment and less noise compared to fixed-bottom foundations because only anchors are needed. Wind turbines can be assembled onshore and then towed to location, shorting construction time at sea."

The notice sent to the Norwegian authority takes place pursuant of the Espoo convention, which covers environmental impact assessments (EIAs) in transnational contexts.

After a public consultation period, extending until Aug. 13, 2021, an EIA report will be made to ascertain how the proposed wind farm could affect marine bird species, commercial fishery and shipping.
