Hexicon Sells UK TwinHub Floating Wind Project After CfD Termination
The title of this post, is the same as that of this article on Renewables Now.
This is the sub-heading.
Floating wind developer Hexicon AB (STO:HEXI) announced it has divested its 32-MW TwinHub offshore wind project in the UK’s Celtic Sea waters, which recently had its contract for difference (CfD) terminated.
These first three paragraphs add some details.
The Swedish firm said it had entered into and completed a sales and purchase agreement (SPA) related to the TwinHub project company, Wave Hub Ltd. The buyer is an unnamed “leading global provider of advanced maritime and offshore engineering solutions.” Financial details were not provided.
Hexicon bought Wave Hub Ltd in 2021, when the site was permitted for wave energy, and later repurposed it for a floating offshore wind project. The scheme secured a 15-year CfD in the fourth allocation round in 2022, which was a first for a development of this type.
Earlier this month, the UK government confirmed that the CfD for TwinHub had been terminated.
It appears that the new owners will be continuing the project.

EU, France Grant EUR 126 Million For BW Ideol’s Floating Foundation Factory
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
BW Ideol has signed the final grant agreement for up to EUR 74 million from the EU Innovation Fund for a factory in Fos-sur-Mer, France, that will produce concrete floating wind foundations. The factory, dubbed Fos3F, has also secured up to EUR 52 million from the French State.
These three paragraphs add more detail.
The final agreement for the EU Innovation Fund grant was signed on 19 March, after BW Ideol revealed in November 2025 that the Fos3F was selected for up to EUR 74 million in funding by the European Commission.
The French government awarded support for the project at the end of 2025 through the C3IV tax credit scheme, dedicated to supporting leading French companies in the Green Industry. The funding from the French State will cover up to EUR 52 million to partially fund development and capital expenditures.
According to BW Ideol, if built, the Fos3F will be a first-of-its-kind factory dedicated to the serial production of concrete floating wind foundations based on the company’s patented Damping Pool.
The factory is stated to have a capacity of thirty foundations per year.
This Google Map shows the location of Fos-sur-Mer.
Note.
- Arles is in the North-West corner.
- Marseille is in the South-East corner.
- The mouth of the Rhône River is in between.
- Fos-sur-Mer is outlined by the red-and-white border.
Google AI says there is significant steel making at the mouth of the Rhône River.
I also asked Google AI, “What turbines will BW Ideol floating foundations support? and received this reply.
BW Ideol’s floating foundations are designed to be universal, supporting all major 15 MW+ offshore wind turbines currently on the market, with scalability to future 20 MW+ platforms. Their concrete barge-type technology—using the Damping Pool® design—is compatible with both existing and next-generation turbine manufacturers.
Key Compatibility Details:
15 MW+ and 20 MW+ Turbines: The foundations are engineered for current large-scale turbines (15 MW+) and are ready to accommodate upcoming 20 MW+ turbines, with designs already certified by DNV.
Proven Technology: The technology has been in operation since 2018 at the Floatgen site in France (using a Vestas V80 2 MW turbine) and in Japan, covering both shallow and deep-water applications.
Universal Application: The design is tailored for diverse metocean conditions and is designed to support the commercial deployment of large turbines in projects like the Buchan Offshore Wind project in Scotland.
Production Scalability: The concrete floating platforms are designed for mass production, capable of being manufactured quickly in a factory setting, such as the proposed Fos-sur-Mer site, to meet the schedules of major developers.
These foundations have received Design Certification from DNV, confirming their suitability for large-scale, commercial floating wind farms.
My Thoughts:
Concrete v. Steel: I used to work with someone, who was a big advocate of concrete yachts. Also check out the Wikipedia entry for the Troll A platform, which is a concrete Norwegian gas platform.
Zero-Carbon: I wouldn’t be surprised if concrete manufacture emits less carbon, than steel.
Port Talbot: Will BW Ideol build a similar factory at Port Talbot? I wrote about the Port Talbot factory in Port Talbot To Become Offshore Wind Hub For Celtic Sea. Both sites are next to a large bay, which would be ideal for parking completed floats and a world-class steelworks.
Buchan: Buchan’s web site says it will use seventy BW Ideol floats and generate I GW, 75 km. to the North-East of Fraserburgh. Google AI said the floats will be built at the Port of Ardersier.
Will A Mini-Steel Mill Be Built At The Port Of Ardersier?
I asked Google AI, the question in the title of this section and received this reply.
Yes, a £300 million green steel mill is planned for the Ardersier Port redevelopment as part of its transformation into a circular Energy Transition Facility. This facility aims to process scrap steel from decommissioned oil rigs into new materials to support offshore wind developments, alongside creating a concrete production plant.
Key details regarding the development:
Purpose: The mill is intended to process scrap from offshore decommissioning.
Technology: It is planned as a green steel plant.
Integration: It is aimed to be integrated into a new, fully circular “Energy Transition Facility”.
Context: While the facility aims for circular steel production, the port is primarily focused on becoming a hub for offshore wind and manufacturing.
Recent developments as of March 2026 suggest a focus on a “scaled back,” more achievable vision by new owners/managers, focusing on floating concrete wind turbine bases. Additionally, recent UK government intervention restricted a large Chinese-backed manufacturing plan at the site due to security concerns.
Port Talbot To Become Offshore Wind Hub For Celtic Sea
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Port Talbot will become the first dedicated hub for floating offshore wind in the Celtic Sea.
These four introductory paragraphs add some detail.
Associated British Ports (ABP) will begin detailed design and engineering work on new port infrastructure after securing grant funding of up to £64m from the UK government.
The project will support the assembly and deployment of floating turbines that will operate in deeper waters off the Welsh coast. ABP said the development could support thousands of jobs and attract hundreds of millions of pounds in further investment.
The UK government said the new port would help deliver clean, homegrown electricity, protect households from volatile fossil fuel markets and create up to 5,000 new jobs.
Redeveloping the port to handle the assembly of wind turbines could position Port Talbot at the centre of a fast-growing clean energy sector.
I have some thoughts.
How Much Wind Power Is Planned For The Western Approaches?
In Ocean Winds Enters Lease Agreement With Crown Estate For 1.5 GW Celtic Sea Floating Wind Project, I published this Google AI estimate of the wind power, that could be developed in the Western Approaches.
How Much Wind Power Is Planned For The Western Approaches?
I asked Google AI, the title of this section and received this answer.
The UK has a target of 50 GW of offshore wind by 2030, with significant projects planned for the Celtic Sea (part of the Western Approaches), which is a key area for 5 GW of floating wind. Total UK offshore wind pipeline capacity exceeds 93 GW, with major developments in this region focusing on floating technology.
Key details regarding wind power in the Western Approaches (specifically the Celtic Sea) include:
Celtic Sea Developments: The area is a primary focus for floating wind projects, designed to capitalize on deep-water potential, with 5 GW of floating wind expected to be deployed across the UK by 2030.
Pipeline and Capacity: The total UK pipeline for offshore wind, which includes the Western Approaches, is 93 GW, and the government is aiming for 43-50 GW of installed offshore capacity by 2030.
Project Status: The region is expected to benefit from the Crown Estate’s leasing rounds aimed at accelerating floating wind, with 15.4 GW of new projects submitted across the UK in 2024.
Wales/South West England Context: Wales has 1.4 GW of projects in the pre-application stage, with some potential for developments off the South West coast.
For more detailed information on specific projects and their development status, you can visit the RenewableUK website and RenewableUK website.
It looks like about 20 GW of offshore wind could be installed in the Western Approaches.
I would expect, a lot of work will be generated in the Port Talbot area.
A Lot Of Steel Will Be Needed
Earlier in the weeek, the UK Government backed the steel industry in Port Talbot, with a press release entitled UK Steel Industry Backed By Major New Trade Measure And Strategy.
Port Talbot Is A Comprehensive, Well-Connected Site
This Google Map shows the site.
Note.
- The M4 running along the site.
- The South Wales Main Line running along the site, with Port Talbot Parkway serving the site.
- The harbour by the station.
- The Tata steelworks marked by the red arrow.
I hope the up to £64 million grant from the government is sufficient for Associated British Ports (ABP) to turn the harbour into a world-class floating wind facility and that the Treasury haven’t been too mean.
BW Ideol, ABP To Explore Serial Production Of Floating Wind Foundations At Port Talbot
I wrote a post with this name in December 2023, before the leases for the Celtic Sea windfarms had been awarded. As one has been awarded to EDf Renewables, BW Ideol seem to have made a good move.
BW Ideol have a web page, which describes their concrete floating wind foundations manufacturing line.
I hope South Wales has got enough concrete?
Welsh Government Backs Marine Power Systems’ Floating Wind Tech With GBP 8 Million
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Welsh government has invested GBP 8 million (approximately EUR 9.4 million) in Marine Power Systems (MPS) to support the commercialisation of its floating offshore wind technology.
These three paragraphs add more detail to the story.
According to the company, the funding will accelerate the deployment of its PelaFlex platform, a floating wind solution designed for deep-water sites where conventional fixed-bottom foundations are not viable.
Marine Power Systems said the investment will help move the technology from advanced development towards commercial-scale deployment and manufacturing. The company also plans to expand its industrial and assembly capabilities in the UK.
The PelaFlex platform has been designed to simplify fabrication, installation and long-term operations while enabling wind farms to be located further offshore where wind speeds are typically stronger and more consistent, MPS says.
The offshore wind industry in Wales seems to be gearing up for a big expansion.
Gwynt Glas is the collective name for the three 1.5 GW floating wind farms in the Western Approaches and in Gwynt Glas And South Wales Ports Combine Strength In Preparation For Multi-Billion Floating Wind Industry, I describe the initial agreement that started the Gwynt Glas project.
To my mind, Associated British Ports and the wind farm developers are making sure they can carpet the Western Approaches, with offshore wind farms.
In Ocean Winds Enters Lease Agreement With Crown Estate For 1.5 GW Celtic Sea Floating Wind Project, I talk in general about the progress of the first three 1.5 GW floating wind farms in Gwynt Glas and in particular about leasing of the third wind farm.
These two posts, indicate that the Port of Port Talbot is preparing itself to produce the floaters for floating wind turbines.
- BW Ideol, ABP To Explore Serial Production Of Floating Wind Foundations At Port Talbot
- Two Ports Advance To Next Stage Of UK Gov Funding For Floating Wind
It certainly appears, that South Wales will be able to build the heavyweight gubbins for floating offshore wind.
According to Was South Wales Once The World’s Largest Coal Exporter? it was, and in 1913, the region produced 57 million tons of coal, with more than half exported.
It does look like South Wales is going to repeat the economic success with offshore energy.
I’ve heard tales from elderly Welshmen talking of the coal ships in the docks of South Wales and will we be seeing gas tankers in the docks of South Wales?
Ocean Winds Enters Lease Agreement With Crown Estate For 1.5 GW Celtic Sea Floating Wind Project
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ocean Winds has entered into an agreement for lease with the Crown Estate for a 1.5 GW floating offshore wind project, for which the developer secured a site in the Round 5 seabed auction last year.
These two paragraphs add detail to the story.
Offshore Wind Leasing Round 5, the UK’s first dedicated floating wind seabed leasing round, was launched in February 2024, offering three areas. In June 2025, the Crown Estate announced Equinor and Gwynt Glas, a joint venture between EDF and ESB, as preferred developers for two project sites and said it was working to ensure the delivery of the full potential capacity of Round 5, which is up to 4.5 GW.
Equinor and Gwynt Glas entered into lease agreements for their floating wind projects in October 2025 and, the following month, the Crown Estate said Ocean Winds had secured the third floating offshore wind site in the Celtic Sea.
This map shows the three wind farms, that make up the Glynt Glas wind farm.
Note.
- It is expected to be built from and connect to the grid at Port Talbot in South Wales.
- The three sites are expected to be commissioned by the early-to-mid 2030s.
- The elongated white dot to the East of the wind farms would appear to be Lundy Island.
- The large bay to the North of Lundy is Carmarthen Bay with Caldey Island at its West end and Llanelli on its East.
- The Gower separates Swansea Bay from Carmarthen Bay.
This Google Map shows the Bristol Channel from the wind farms in the West to Cardiff and Hinkley Point.
Note.
- Along the North coast of the Bristol Channel, working from West to East, my 78-year-old eyes can pick out Milford Haven, Pembroke, Caldey Island, Tenby, Llanelli, Swansea, Port Talbot, Porthcawl, BridgendCaerphilly, Cardiff and Newport.
- Coming back along the South Coast, I can see Weston-super-Mare, Hinkley Point C and the tip of Lundy Island in line with Tenby.
- The three sections of Glynt Glas will each generate 1.5 GW, making a total of 4.5 GW.
- Hinkley Point C when completed, will be a 3.26 GW nuclear power station.
- There is also a 2.2 GW gas-fired power station at Pembroke.
Nearly 8 GW of renewable electricity should be enough to convert Port Talbot steelworks to the manufacture of green steel.

All Five Halted US Offshore Wind Farms Resume Construction
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
All five US offshore wind farms under construction that received stop-work orders from the US government have been cleared to continue building, with Ørsted’s Sunrise Wind project the fifth project to be granted a preliminary injunction as part of a lawsuit challenging the order issued by the Director of the Department of the Interior’s Bureau of Ocean Energy Management (BOEM) on 22 December 2025.
I would have loved to have been a fly on the wall of the Oval Office in the White House, as what words could the dumbest United States President of my lifetime possibly use to put any positive spin on such an overwhelming five-round defeat, where he was screwed, glued and tattooed to borrow an expression from Brian, who was one of my favourite accountants.
This table summarises the five wind farms.
- Coastal Virginia Offshore Wind-Commercial – 2600 MW – Operation in 2027.
- Empire Wind 1 – 816 MW – Operation in 2026.
- Revolution Wind – 704 MW – Operation in 2026.
- Sunrise Wind – 924 MW – Operation in 2027.
- Vineyard Wind 1 – 804 MW – Operation in late 2026.
The five farms total nearly 6 GW.
This is what Google AI says about the usefulness of 6 GW to power typical United States houses.
6 gigawatts (GW) of power can supply approximately 5 million US homes, based on recent large-scale energy capacity deals. Depending on energy efficiency and regional usage, this capacity typically translates to around 750,000 homes per 1 GW, meaning 6 GW can cover a range of roughly 4.5 million to 5 million households.
I doubt Trump will give up gracefully.
Offshore Wind Turbines In 2025: China Continues Leading In Single-Unit Capacity, Vestas’s 15 MW Turbine Installed At Offshore Wind Farms
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
In offshoreWIND.biz‘s 2024 annual wind turbine overview, you could have read about the first 16 MW floating wind platform installed offshore and a 26 MW prototype under construction, both in China, and a 21 MW prototype being assembled in Europe. Wind turbine generator (WTG) technology did not stop progressing in 2025, with Chinese OEMs still leading capacity-wise, while in Europe, first offshore wind farms are now featuring 15 MW turbines and a 21+ MW model was installed onshore for testing.
The article is very much a must-read and there is a lot of innovation going on.
As a comparison, between 2020 and 2026 we commissioned or are building these offshore wind farms in the UK.
- East Anglia One – 2000 – 714 MW – 102 x 7 MW
- Hornsea One – 2020 – 1218 MW – 174 x 7 MW
- Kincardine – 2021 – 49.5 MW – 6 x floating
- Hornsea Two – 2022 – 1386 MW – 165 x 8 MW
- Moray East – 2022 – 950 MW – 100 x 9.5 MW
- Triton Knoll – 2022 – 857 MW – 90 x 9.5 MW
- Seagreen Phase 1 – 2023 – 1400 MW – 114 x 10 MW
- Dogger Bank A – 2025 – 1235 MW – 95 x 13 MW
- Moray West – 2025 – 882 MW – 60 x 14 MW
- Neart Na Gaoithe – 2025 – 450 MW – 54 x 8 MW
- Dogger Bank B – 2026 – 1235 MW – 95 x 13 MW
- East Anglia 3 – 2026 – 1372 – 95 x 14 MW
- Sofia – 2026 – 1400 MW – 100 x 14 MW
Average sizes for the various years are as follows.
- 2020 – 7 MW
- 2021 – floating
- 2022 – 8-9.5 MW
- 2023 – 10 MW
- 2025 – 8-14 MW
- 2026 – 13-14 MW
It can clearly be seen that in the last few years, turbines have been getting bigger.
I have some thoughts on the article.

UK Gov’t Tweaking CfD Rules Ahead Of 8th Allocation Round, Proposes ‘Other Deepwater Offshore Wind’ Category
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The UK government has launched a consultation on proposed refinements to the Contracts for Difference (CfD) scheme ahead of Allocation Round 8 (AR8) and future rounds, including targeted changes to the terms concerning offshore wind and floating wind projects.
These two paragraphs add more details.
The consultation, published by the Department for Energy Security and Net Zero, seeks industry feedback on contractual and eligibility adjustments, some of which are intended to reflect the increasing scale and complexity of offshore wind developments, specifically floating and other deepwater projects.
For floating offshore wind, the government is proposing changes to CfD contract terms to better align with the technology’s development timelines. These include a proposed extension of the Longstop Period to give floating wind projects more time to commission and avoid termination of their CfD contract.
The government also wants to lower the Required Installed Capacity (RIC) threshold for floating offshore wind projects.
Currently, all CfD technologies are required to deliver a minimum of 95 per cent of the capacity they have contractually agreed to install, except for (fixed-bottom) offshore wind, whose RIC is set at 85 per cent to reflect the construction risks, such as encountering unsuitable seabed conditions after work has commenced. As floating wind projects, which were so far in the range of 100 MW, have grown in scale and complexity, the government plans to apply the same RIC requirement as for fixed-bottom offshore wind.
The CfD scheme currently supports two categories of offshore wind technology: fixed-bottom offshore wind and floating offshore wind, with the regulations in use (Allocation Regulations 2014) considering only the foundation designs that float to be floating offshore wind. With the ODOW category, the government wants to make room for the novel hybrid foundation designs, “which may be suitable for deepwater deployment but do not technically float and would therefore not be considered eligible as ‘floating foundations’ under the existing legal definition of ‘floating offshore wind’.”
This last paragraph sums up the reasons for the changes.
The proposed refinements are intended to ensure the CfD scheme remains fit for purpose as offshore wind technologies evolve, while maintaining investor confidence and supporting timely project delivery.
Hopefully developments at ports like Belfast, East Anglia, Inverness & Cromarty FreePort,Lowestoft and Tyne will encourage to develop wind farms around the shores of the UK.
SeaTwirl AB Signs Agreement To Explore Ehe Feasibility Of Electrification Of Aquaculture In Chile
The title of this post, is the same, as that of this press release from SeaTwirl.
This is the sub-heading.
SeaTwirl AB has entered into an agreement to carry out a feasibility study for electrification of fish farms together with a global industrial supplier. The intention of the collaboration is to assess the use of SeaTwirl’s floating vertical-axis wind turbines to provide renewable electricity to offshore-based equipment at aquaculture assets in Chile.
These three paragraphs add more details.
The feasibility study will cover a comprehensive scope, including energy demand and power system requirements, environmental site conditions, cost assessments, supply chain opportunities, and logistics in Chilean waters with the intention to reduce dependence on diesel. The study is expected to be completed during 2026, and the results will help determine next steps.
Chile is home to one of the largest aquaculture industries in the world, and the sector is pursuing ambitious sustainability goals including lower emissions, increased use of renewable power and reduced risk of spills. While the contractual value of the agreement is limited, at approximately SEK 0,8 million, the engagement will generate revenue and represent an important step in SeaTwirl’s commercialization effort.
“This collaboration marks an exciting step towards our purpose to enable floating wind power wherever it is needed, and to expand the use of floating wind technology beyond traditional grid-connected applications. The aquaculture industry has a clear need for offshore renewable energy, and we believe our technology can deliver a robust and cost-effective solution. It is also a major milestone to become involved in the southern hemisphere where many of the challenges we try to address, such as limited availability of cranes, vessels, and yard infrastructure, may be more challenging than in the north. We see significant potential in the aquaculture segment and look forward to beginning this journey in South America”, says Johan Sandberg, CEO of SeaTwirl.
I do find it strange, that the two vertical wind turbines, that both seem to be more than prototypes are both Scandinavian.
The Ventum Dynamics turbine, that I talked about in Are These Turbines An Alternative To Solar Panels? is Norwegian and this one is installed on Skegness Pier.
IKEA could sell these for DIY-enthusiasts to assemble and erect. On my stud, I used to have a barn, that could certainly have taken two of these 1.5 KW VX175 turbines.
This link is video of a dancing and swimming SeaTwirl.
If you follow, the SeaTwirl video to its conclusion, you’ll see one being erected in the sea. I can assure you that in the 1970s, my 25-year-old self, did the calculations for a reusable oil production platform called a Balaena, which erected on the same principle. So, I’m fairly certain, that SeaTwirls can be an alternative to traditional wind turbines.
Offshore Wind Developer Gets DNV Concept Certification for Floating Foundation Design
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
BayWa r.e. has received concept certification from DNV for its BayFloat floating wind semi-submersible concrete substructure and mooring system design. The design was validated using the 22 MW generic reference turbine “IEA-22-280-RWT”
These three introductory paragraphs give a few more details.
The certification process was conducted in accordance with DNV-SE-0422:2021-09 “Certification of floating wind turbines” scheme, including DNV-ST-0119:2021-06 “Floating wind turbine structures” as the governing standard, BayWa r.e. says.
The assessment concluded that the BayFloat concrete floating substructure, including the mooring system design, is feasible for further development and qualifies for DNV concept-level certification.
BayWa r.e. collaborated with the engineering company Ramboll on the design and certification process, with Ramboll providing design services, expert insights and engineering advice.
Note.
- Certification must be a good thing.
- If you are unfamiliar with DNV, then their Wikipedia entry, is a good place to start.
- As I was doing the calculations for a floating oil platform in the 1970s, I don’t see why floating wind turbines won’t work!
- Especially, as floating wind turbines, seem to have a higher capacity factor than fixed.
- Concrete also worked for oil and gas platforms, so why won’t it work for wind?
In fact I quite like this design.
These are some other thoughts and information.
The Buchan Wind Farm
Baywa r.e. are also developing the 960MW Buchan floating wind farm about 75 km North-East of Fraserburgh.
The Buchan Wind Farm web site says this about the technology to be used.
The project has identified BW Ideol’s patented Damping Pool® floating substructure as its preferred foundation option, with BW Ideol working actively to establish a manufacturing centre at the Ardersier Energy Transition Facility being developed at the former oil and gas fabrication yard on the Moray Firth.
Perhaps, Baywa r.e. are seeing if they can do better.
The Original Article
The original article also links to several designs of floating wind float design, so it is well worth a full read.
But then, each have their advantages in materials used, ease of construction, methods of assembly, ease of tow-out and erection and most importantly; cost!
