Denmark's energy appeals board has rejected challenges against two offshore wind farms developed under the country's old 'open door' scheme, paving the way for construction to begin.

The Odal Vind project in Norway is now back online following a breakage that triggered investigations last year. 

Swedish firm SeaTwirl has unveiled plans for a two-bladed vertical-axis floating offshore wind turbine on a rotating spar foundation with “flat-pack assembly”.

Concerns are growing about the wake effect and its impact on offshore wind farms, with major developers locked in disputes over projects being built adjacent to one another. But how will the wake effect impact project buildout, and how can it be mitigated? Windpower Monthly investigates.

Developers are losing optimism for the future of floating offshore wind due to delivery delays, investment risk and slow policy implementation, according to new research from the Westwood Global Energy Group.
