New Report Highlights Potential for Co-location of Offshore Wind and Fish Farming
Freja Offshore and a Nordic consortium have released the final report from OFFWOFF, a pioneering project that explores how floating wind power and offshore fish farming can coexist within the same marine areas. Supported by Nordic Innovation, the project points towards a more resource-efficient and sustainable use of our seas.
Using Freja Offshore’s planned Mareld wind farm in the Skagerrak as a case study, OFFWOFF analysed the technical, environmental, and commercial conditions for co-location. The results show that combining offshore energy and food production is not only possible, it can deliver clear benefits for both society and industry.
“By co-locating wind power and fish farming, we can make smarter use of ocean space, generating green electricity while also supporting sustainable food production. It opens up new farming areas, strengthens collaboration at sea, and gives Sweden a real opportunity to increase self-sufficiency in salmon – a key issue for both climate resilience and food security,” says Marcus Thor, Board of Director at Freja Offshore.
Floating wind farms in deeper waters, such as Mareld, offer excellent conditions for salmon farming. The cold, fast-moving waters reduce the risk of sea lice and oxygen deficiency, which supports fish health and animal welfare. In addition, these zones restrict bottom trawling, giving marine ecosystems a chance to recover. When fish farming is added to these protected areas, they become sites of active food production, allowing us to preserve and make sustainable use of the ocean at the same time.
The project shows that combining offshore aquaculture with floating wind power can contribute to stable, local food production without putting pressure on coastal environments. It also promotes more effective marine spatial planning and better use of ocean space.
OFFWOFF was carried out in collaboration with SubFarm (Norway), DHI (Denmark), ÅKP (Norway), GCE Blue Maritime Cluster (Norway), and Fyrbodal Association of Local Authorities (Sweden), with Freja Offshore serving as project lead.
The report is part of Nordic Innovation’s programme for a sustainable ocean economy, and the full report is available on Nordic Innovation's website.
