Two More Floating Wind Projects In The Celtic Sea

In Two Celtic Sea Floating Wind Projects Could Be Delivered By 2028, I said this.

There now appears to be four floating wind farms under development in the Celtic Sea between the South-West corner of Wales and the Devon and Cornwall Peninsular.

  • Blue Gem Wind – Erebus – 100 MW Demonstration project  – 27 miles offshore
  • Blue Gem Wind – Valorus – 300 MW Early-Commercial project – 31 miles offshore
  • Falck Renewables and BlueFloat Energy – Petroc – 300 MW project – 37 miles offshore
  • Falck Renewables and BlueFloat Energy Llywelyn – 300 MW project – 40 miles offshore

But they do create a starter for a GW.

Last night, I found two other projects being developed in the Celtic Sea, under the collective name of the Llŷr Project.

The sponsoring company, which appears to be called Llŷr Wind has a web site, with a title of Harnessing Welsh Energy, which has this outline description underneath.

Situated off the Pembrokeshire coast, in southwest Wales, is a flagship project that could transform the world’s ability to generate renewable electricity from wind. The Llŷr projects are exploring the potential of two innovative floating offshore wind technologies.

The next statement is key.

Combined, the two 100MW projects will generate enough renewable electricity to power around 250,000 homes. If successful, we will be able to offer highly cost-effective, floating offshore wind farms to the rest of the world by 2030.

The Llŷr Project would appear to be a research project to find the best way to generate electricity using floating wind turbines in deep water.

  • It appears that the two wind farms will use different floats for the turbines.
  • The Llŷr projects are located in the approaches to the Bristol Channel in the Celtic Sea approximately 40 kilometres offshore at depths averaging 60-70 metres.
  • These offshore sites enjoy high average windspeeds which are, typically, in excess of 10 metres per second. That is over twenty miles per hour.
  • Each 100MW project will comprise 6 to 8 next-generation turbines which are too large to be deployed on land.
  • 6 x 20 MW turbines will be 120 MW.
  • 8 x 12 MW turbines will be 96 MW.
  • Each project will have an offshore substation.
  • There will be up to two connections for each substation.
  • Will the Llŷr Projects test manufacturers’ new turbine designs?
  • It is hoped that installation of the turbines will start in 2025/26, with power being delivered in 2026/7.
  • The project is being developed by Floventis Energy, which is a joint venture of SBM Offshore and Cierco.

It does look to me that SBM Offshore, who are a Dutch company, are using their extensive oil and gas experience to develop floating offshore wind.

This appears to be a very well-thought out research project in a location, where there is everything needed.

  • Lots of wind, which can be boosted by dragons if needed.
  • Deep water.
  • Ports for assembly of turbines onto floats.
  • Steelworks and fabrication.
  • Good electrical connections to the National Grid.
  • Excellent universities.
  • Good transport connections.
  • An experienced engineering workforce.

There is also the ultimate potential of 50 GW of floating offshore wind in the Celtic Sea.


The Llŷr Project could have a very positive input into the worldwide development of floating offshore wind.

I have read the web sites of Floventis, SBM Offshore and Cierco and these companies appear to be aiming to dominate the floating offshore wind industry.

Their strategy is stated on the Floventis web site.

Our strategy is simple. We plan to maximize the local benefits of our projects and minimize their impact. Our technologies are far more benign than conventional offshore wind and more suited for deployment in remote and sensitive environments.

Already driving demonstration projects in California and the UK, Floventis is building a portfolio of projects to take floating offshore wind, through a stepwise process – increasing project size, to full scale commercial development proposals by 2030.

We believe that the floating offshore wind industry is a model for a “just transition” to clean energy, at scale, which will reward communities, in the broadest sense, with skilled jobs and enhanced social equity.

I can certainly live with that! And I’m certain the world can too!
