Equinor Sets Sights On Gigawatt-Scale Floating Offshore Wind Projects In Celtic Sea
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the opening paragraph of the article.
Equinor has disclosed its interest in developing gigawatt-scale floating offshore wind in the Celtic Sea, with the upcoming Celtic Sea floating wind seabed leasing round in view.
These are some other points from the article.
- The Crown Estate is planning a seabed leasing round in the Celtic Sea in 2023.
- As the developer and soon-to-be operator of two of the world’s first floating offshore wind farms, Equinor said it views new floating opportunities in the Celtic Sea with great interest.
- Project development areas are being prepared by The Crown Estate for the development of gigawatt-scale floating offshore wind projects.
Equinor could move into the Celtic Sea in a big way.
On the Projects page of the Blue Gem website, this is said about floating wind in the Celtic Sea.
Floating wind is set to become a key technology in the fight against climate change with over 80% of the worlds wind resource in water deeper than 60 metres. Independent studies have suggested there could be as much as 50GW of electricity capacity available in the Celtic Sea waters of the UK and Ireland. This renewable energy resource could play a key role in the UK meeting the 2050 Net-Zero target required to mitigate climate change. Floating wind will provide new low carbon supply chain opportunities, support coastal communities and create long-term benefits for the region.
How much of this possible 50 GW of offshore wind in the Celtic Sea will be leased by the Crown Estate in 2023?
Floating Wind Farms At Sea To Create 29,000 Jobs – Crown Estate
The title of this post, is the same as that of this article on the BBC.
These three paragraphs introduce the article.
Plans to generate electricity through floating wind farms off the south Wales coast could create thousands of new jobs, according to the Crown Estate.
The property business owned by the monarch but run independently said the new industry could create about 29,000 jobs, including 10,000 in Wales.
It is leasing the space to generate enough power for four million homes.
Will Wales be the world’s next offshore wind powerhouse?
Wind power experts have said there is a potential for 50 GW of offshore wind power in the Celtic Sea and the BBC article talks of an investment of £43.6 billion by 2050.
The process has started, but will the engineers be able to tame the dragons?
Accelerating The Delivery Of Offshore Wind Farms
It is one of Kwasi Kwarteng’s ambitions to accelerate the delivery of offshore wind farms.
In The Growth Plan 2022, these groups of wind farms are mentioned.
- Remaining Round 3 Projects
- Round 4 Projects
- Extension Projects
- Scotwind Projects
- INTOG Projects
- Floating Wind Commercialisation Projects
- Celtic Sea Projects
My thinking in this post, will probably apply to all of these groups.
These are my thoughts.
Accelerating Delivery Of A Wind Farm
This will have these positive effects.
- Electricity will be delivered earlier.
- Customers will have a more secure supply of electricity.
- The wind farm owner will start to be paid for their electricity.
- The Crown Estate will start to be paid for their leases. Although, these might start at signing.
- National Grid will be paid for the transmission of the electricity.
- An energy storage company could be paid for storing surplus electricity.
- Construction teams and engineers can move on to the next project.
- Expensive construction hardware like ship-mounted cranes will no longer be needed.
- I also suspect that the government will raise some taxes from the various companies involved.
It looks like it’ll be winners all round.
How Will Delivery Be Accelerated?
These are some thoughts.
Overall Project Time
In How Long Does It Take To Build An Offshore Wind Farm?, I came to these conclusions.
- It will take six years or less from planning consent to commissioning.
- It will take two years or less from the start of construction to commissioning.
I suspect that as we have been building offshore wind farms for some years, that it will be very difficult to reduce these times significantly.
But as some wind farms take quite a few years to progress from the initial proposal to planning consent, I suspect that improvements to the planning process may speed up the overall construction time of a wind farm.
Project And Resource Management
Good project and resource management will always help.
Better Design And Construction Methods
I always remember in the early days of North Sea Oil, being told by a very experienced project manager that construction of production platforms was accelerated by the availability of larger and more powerful cranes.
Are we approaching the design of the ultimate wind farm? I doubt it, as in the last few months, I’ve seen two very radical new designs.
In Hexicon Wins UK’s First Ever CfD Auction For Floating Offshore Wind, I show this image of one of their TwinHub turbine installations being towed into place.
The TwinHub home page has a title of The First Floating Offshore Wind Project in The Celtic Sea.
This is the description on the page.
The TwinHub offshore wind demonstration project intends to prove how Hexicon’s innovative design with two turbines on one floating foundation can further reduce the Levelized Cost of Energy (also referred to as LCoE) before large scale commercialisation. The TwinHub project is a stepping stone to help kick-start floating wind in the Celtic Sea, an area identified as a hotspot for floating wind by the UK Government. It will pave the path for larger and larger projects to help support The Crown Estates’ ambitious target of 4GW of floating wind in the Celtic Sea.
Scroll the page down and there is a fascinating short video of a pair of wind turbines in operation.
- It appears that when there is no wind, it automatically goes into a safe parked mode.
- As the wind rises, one turbine starts up.
- The second turbine starts up and the float turns so they face the wind.
It appears to be a classic example of disruptive innovation.
I have a feeling that this type of installation might have generation, assembly and cost advantages over a single turbine mounted on a single float.
RCAM Technologies are also creating interesting designs for mounting turbines and energy storage using 3D-printed concrete.
What Ts The UK Government Doing To Accelerate Projects?
This article on offshoreWIND.biz, was published in late September 2022 and is entitled BREAKING: UK Puts Massive Amount Of New Offshore Wind Capacity On Fast Track and this is the first paragraph.
The UK will speed up planning and development consent processes for projects from the recently completed, currently ongoing, and upcoming (floating) offshore wind leasing rounds to bring new energy capacity online faster and facilitate economic growth and job creation.
The article is based on what Kwasi Kwateng said on the 23rd of September about speeding up projects in the 2022 Growth Plan.
A Quick Summary Of Our Wind Energy
The article has this paragraph, which summarises our wind energy.
For the UK, which currently has around 14 GW of offshore wind capacity in operation and 8 GW under construction, the projects from the listed auction rounds could bring well beyond the targeted capacity for 2030, which was recently raised to 50 GW.
I can see the target being raised again to at least 60 GW.
