DEME Concessions & Youwind: Engineering Excellence Meets Transparent Digital Innovation

As part of the group DEME (Euronext: DEME), DEME Concessions develops and invests in offshore wind projects, working with partners to turn opportunities into deliverable projects. Its development track record includes C-Power, Rentel, SeaMade and Merkur, while its development portfolio includes the Bowdun project, a planned 1 GW fixed-bottom offshore wind farm in Scotland, being developed through Thistle Wind Partners. This combines hands-on project experience with a long-term investment perspective.  

Successful development requires more than selecting a turbine or designing a layout. It means understanding how site conditions, technology choices, energy production, supply chain constraints and project costs interact, and how these decisions influence overall project viability. 

 DEME Concessions brings these considerations together through an integrated approach to technical, permitting and commercial assessment. Drawing on the wider DEME’s offshore expertise, it maintains a clear distinction between its role as developer and investor and the group’s offshore’s contracting activities.  

This development perspective sets the context for its collaboration with Youwind: bringing digital tools alongside engineering expertise to support informed project assessment and optimisation. The focus is not simply on analysing individual parameters, but on understanding the trade-offs that shape a competitive and deliverable offshore wind project. 

One of the aspects DEME Concessions values most in Youwind is something that often goes unnoticed in digital tools: transparency. 

In an industry where decisions carry significant technical and financial implications, understanding how results are generated is just as important as the results themselves. 

For DEME Concessions, Youwind’s platform guide, and the clarity it provides on methodologies and data sources, has been an important factor. 

It ensures that the platform is not seen as a “black box,” but as a tool that engineers can fully trust, interrogate, and integrate into their own processes. 

DEME Concessions uses Youwind as a powerful tool for preliminary site selection, one of the most critical phases in offshore wind development. At this stage, the ability to explore multiple options quickly and effectively can significantly influence the direction of a project. 

Here, scenario analysis becomes essential. 

By creating and comparing different configurations within the platform, DEME’s teams can evaluate trade-offs, test assumptions, and identify optimal solutions early in the process. 

What makes the relationship between DEME Concessions and Youwind particularly strong is that it goes beyond digital interaction. 

Through regular sessions and in-person meetings, both teams have built a connection grounded in knowledge exchange and mutual respect. 

It’s a collaboration where learning flows both ways. 

 As David Ramírez, Project Development Engineer at DEME Concessions, shares: 

“The collaboration is highly valued, and it reflects the right path for continuing to work together, strengthening our shared knowledge in offshore wind farm development.” 

 This sentiment is echoed by Youwind’s CEO, Anna Rivera: 

“Our collaboration is not merely digital. We have had the opportunity to meet in person at their premises and at key industry events. This has allowed us to take the collaboration a step further, exchanging know-how and learning from each other.” 

The collaboration between DEME Concessions and Youwind is a clear example of how industry leaders and digital innovators can work together to push boundaries. 

For DEME Concessions, it means having a tool that supports early-stage decisions with transparency, flexibility, and speed.
For Youwind, it means evolving with one of the most experienced players in the industry and continuously refining the platform to meet emerging needs. Together, they are not just optimizing workflows, they are contributing to a smarter, more connected approach to offshore wind development.
