Ossian Floating Wind Farm Could Have Capacity Of 3.6 GW
The title of this post, is the same as that of this article on offshoreWIND.biz,
This is the first paragraph.
SSE Renewables, Marubeni Corporation, and Copenhagen Infrastructure Partners (CIP) have identified an increase in the potential overall project capacity for their Ossian floating wind project in Scotland from 2.6 GW to up to 3.6 GW.
It appears that surveys have shown that the wind farm can be bigger.
About The Name Ossian
This press release from SSE is entitled New Offshore Wind Farm To Take Name From Scottish Literature.
These three paragraphs explain the name and the partners behind the project.
A new wind farm project in Scotland is to take its name from an historic series of books which depict the epic quests of a third-century Scottish leader, following his adventures across rolling seas.
Ossian (pronounced ‘os-si-un’) from The Poems of Ossian is to be the name for the proposed new offshore wind farm across 858 km2 of seabed in waters off the east coast of Scotland.
The project will be delivered by the partnership of leading Scottish renewable energy developer, SSE Renewables, Japanese conglomerate Marubeni Corporation (Marubeni) and Danish fund management company Copenhagen Infrastructure Partners (CIP).
I don’t think the three partners will have any difficulty raising the extra finance to expand the wind farm.
Where Is The Ossian Wind Farm?
This Crown Estate Scotland map shows the position of each of the Scotwind wind farms.
Note, that the numbers are Scotwind’s lease number in their documents.
The Ossian wind farm is numbered two.
At present, the South Eastern group of wind farms are as follows.
- 1 – BP – Fixed – 2.9 GW
- 2 – SSE – Floating – 2.6 GW
- 3 – Falck – Floating – 1.2 GW
- 4 – Shell – Floating – 2.0 GW
- 5 – Vattenfall – Floating – 0.8 GW
- 6 – DEME – Fixed – 1.0 GW
This totals to 10.5 GW, which would be 11.5 GW, if the capacity of Ossian is increased.
Will Ossian And Nearby Wind Farms Be Developed As A Co-Operation?
The six companies involved in this group of wind farms, are all experienced developers of wind farms or oil and gas fields.
They also come from all around the world, so I can see the best technology being employed on this group of wind farms.
Will Other Wind Farms In The Group Be Expanded?
The surveys at Ossian appear to have shown that the area is ideal for floating wind and this is enabling the expansion of the farm.
I wouldn’t be surprised to see some of the other wind farms be expanded.
I also feel that floating wind farms like Ossian, where it is likely that all the turbines on their floats are connected to a central substation, that could also be floating, may be a lot easier to expand.
Does Ossian Wind Farm Have A Web Site?
Not that Google can find, although ossianwindfarm.com appears to be under construction.
Ocergy Floaters Selected For 100 MW Project Off Scotland
The title of this post, is the same as that of this article on Splash247.com.
These two paragraphs outline Ocergy’s OCG-Wind foundation technology.
The Salamander floating offshore wind project, a joint venture between Simply Blue Group, Ørsted and Subsea 7, has awarded the pre-FEED (front-end engineering design) deal to Ocergy for its OCG-Wind foundation technology.
The US-based Ocergy has developed a novel semisub floater called OCG-Wind, to support turbines larger than 10 MW, designed for the development of large-scale wind farms. It is targeting a levelised cost of energy (LCOE) that can start to drive reductions in floating offshore wind farms to eventually be competitive with fixed offshore wind farms.
Note.
- There is a picture showing two turbines on OCG-Wind floats.
- Salamander is intended to be an INTOG project of 100 MW.
- The floaters are expected to be fabricated at Global Energy Group’s Port of Nigg.
- ERM’s Dolphyn electrolysis, desalination and hydrogen production concept is also planned for the project.
The Salamander project is certainly going for a lot of innovation.
Metocean Measurement Campaign To Start At 1 GW Scottish Floating Wind Farm Site
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the introductory paragraph.
Partrac will soon deploy a floating LiDAR Buoy at the site of the Buchan floating wind project offshore Scotland, which is being developed by Floating Energy Allyance (FEA), a consortium comprising BW Ideol, Elicio, and BayWa r.e.
It appears, that the Buchan floating wind farm is the first of the floating Scotwind Leasing round of projects to get going in a meaningful way.
The article details some of the design details of the wind farm.
- The site is located some 75 kilometres to the northeast of Fraserburgh on the Aberdeenshire coast,
- The Floating Energy Allyance consortium plans to build a floating offshore wind farm with a capacity of approximately 1 GW, whose wind turbines will be installed on BW Ideol’s Damping Pool floating foundations.
- This page on the BW Ideol web site describes their Damping Pool technology.
- The patented square barge-like floats can be used for offshore wind turbines, substations and hydrogen electrolysers.
BW Ideol appear to be a French company with projects in France, Japan, Taiwan and now Scotland.
The home page of the BW Ideol web site opens with a promotional and explanatory video of their technology.
X1 Wind – Disrupting Offshore Wind
The X1 Wind web site talks about disrupting offshore wind.
On the home page, they have this statement.
Oceans Contain The Largest Energy Resource On The Planet, Which Remains Untapped
They back it up with this reference.
We estimate the total global technical potential of offshore wind as 71 TW (World Bank, 2021), of which 70% is in deep waters, suited to floating wind.
The home page also has a continuous video of their floating wind turbine, which they call a PivotBuoy.
- The wind turbine is mounted on a triangular float.
- The turbine nacelle is supported on a tripod.
- The turbine faces downwind.
- The float is held in place by a single point mooring.
The float and the turbine automatically align with the wind.
This article on offshoreWIND.biz is entitled X1 Wind Installs Downwind Floating Prototype and gives more details of the turbine.
It’s certainly different.
Rishi Sunak To Reimpose Fracking Ban
The title of this post, is the same as that of this article on The Telegraph.
This is the first paragraph.
The new PM made the commitment during his first session of PMQs on Wednesday, reversing Liz Truss’s controversial decision to overturn it.
I think it is the right call.
Here’s why!
Cerulean Winds Massive Decarbonisation Project
Consider.
- At present ten percent of our gas is used to power the oil and gas rigs in the seas around our coasts. The gas is fed into gas-turbines to generate electricity.
- One simple way to increase gas production by this ten percent, would be to decarbonise the rigs by powering them from nearby wind farms with green electricity and green hydrogen as the Norwegians are proposing to do.
- A British company; Cerulean Winds has proposed under the Crown Estate INTOG program to decarbonise a significant part of the oil and gas rigs, by building four 1.5 GW wind farms amongst the rigs.
- The majority of the energy will be sold to the rig owners and any spare electricity and hydrogen will be brought ashore for industrial and domestic users.
- This massive project will be a privately-funded £30 billion project.
- And when the oil and gas is no longer needed, the UK will get another 6 GW of offshore wind.
We need more of this type of engineering boldness.
This page on the Cerulean Winds web site gives more details.
INTOG
This document on the Crown Estate web site outlines INTOG.
Other Projects
Decarbonisation has also attracted the attention of other developers.
I can see Rishi Sunak being offered several projects, that will increase our oil and gas security, by some of the world’s best engineers and most successful oil companies.
Rishi Sunak’s ban on fracking will only increase the rate of project development.
We live in extremely interesting times.
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?
Q&A: What does ‘Subsidy-Free’ Renewables Actually Mean?
The title of this post, is the same as that of this article on Carbon Brief.
This is the first paragraph.
Recent announcements in the UK and across the rest of Europe seem to be ushering in a new era of “subsidy-free” renewables, which can be deployed without government support.
The article gives a detailed explanation and is a must-read.
BayWa r.e. Unveils Subsidy-Free Floating Wind Project Offshore Portugal
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the first paragraph.
BayWa r.e. has officially applied to secure the rights for an exclusive use of the seabed for a commercial-scale floating offshore wind project in Portugal, which the company said will be the first subsidy-free floating wind farm in the world.
Note.
- BayWa are a German company headquartered in Munich.
- The windfarm will have a 600 MW capacity in total, in a dedicated zone off the coastline of Viana do Castelo.
- It will be a floating wind farm.
- Viana do Castelo is situated at the mouth of the Lima River and is about 74 km. to the North of Porto.
But surely the most significant fact about this project is that it is subsidy-free.
BayWa And Subsidy-Free Wind Farms
This page on the BayWa web site is entitled BayWa r.e. Sells UK’s First Subsidy-Free Wind Farm.
This is the first paragraph.
BayWa r.e. has reached a milestone for itself and the UK renewable energy sector with the completion and sale of the country’s first subsidy-free windfarm to James Jones & Sons Ltd and London-based specialist asset manager, Gresham House Asset Management.
Note.
- This is the first time, I’ve seen Gresham House associated with wind farms.
- BayWa appear to have a fifteen year agreement with Tesco for the generated electricity.
The whole page is a must read.
Conclusion
Does this mean, that we will be seeing subsidy-free floating wind farms around the UK?
Get the engineering, manufacturing and financial support right for floating wind farms in the UK and wind farms could be bumper-to-bumper around these islands.
Plans Emerge For 8 GW Of Offshore Wind On Dogger Bank
Wikipedia has an entry, which is a List Of Offshore Wind Farms In The United Kingdom.
The totals are worth a look.
- Operational – 13279 MW
- Under Construction – 4125 MW
- Proposed Under The UK Government’s Contracts For Difference Round 3 – 2412 MW
- Proposed Under The UK Government’s Contracts For Difference Round 4 – 7026 MW
- Exploratory Phase, But No Contract for Difference – Scotland – 24,826 MW
- Exploratory Phase, But No Contract for Difference – England – 14,500 MW
Note.
- That gives a Grand Total of 66,168 MW or 66.168 GW.
- The government’s target is 50 GW of offshore wind by 2030.
- The typical UK power need is around 23 GW, so with nuclear and solar, we could be approaching three times the electricity generation capacity that we currently need.
The figures don’t include projects like Berwick Bank, Cerulean Wind, Norfolk Vanguard or Northern Horizons, which are not mentioned in Wikipedia’s list.
I regularly look at the list of wind farms in this Wikipedia entry and noticed that the number of Dogger Bank wind farms had increased.
They are now given as.
- Dogger Bank A – 1200 MW – Completion in 2023/24
- Dogger Bank B – 1200 MW – Completion in 2024/25
- Dogger Bank C – 1200 MW – Completion in 2024/25
- Dogger Bank D – 1320 MW – No Completion Given
- Dogger Bank South – 3000 MW – No Completion Given
Note, that gives a Grand Total of 7920 MW or 7.920 GW.
This article on offshoreWIND.biz is entitled BREAKING: SSE, Equinor Plan 1.3 GW Dogger Bank D Offshore Wind Project.
It was published on the October 6th, 2022 and starts with this summary.
SSE Renewables and Equinor are looking into building what would be the fourth part of Dogger Bank Wind Farm, the world’s largest offshore wind farm, whose three phases (A, B and C) are currently under construction. Surveys are now underway at an offshore site where the partners want to develop Dogger Bank D, which would bring Dogger Bank Wind Farm’s total capacity to nearly 5 GW if built.
Obviously, there are a few ifs and buts about this development, but it does look like SSE Renewables and Equinor are serious about developing Dogger Bank D.
More Dogger Bank Gigawatts for UK As RWE Moves Forward With Two 1.5 GW Projects
This subheading describes, the 3 GW wind farm, that I listed earlier as Dogger Bank South.
These three paragraphs describe the projects.
RWE is now moving forward with two new offshore wind farms in the Zone, each with a 1.5 GW generation capacity, after the company obtained approval from the UK Secretary of State for Business, Energy and Industrial Strategy (BEIS) to enter into an Agreement for Lease with The Crown Estate this Summer, following the Round 4 leasing process.
The wind farms will be built at two adjacent sites located just southwest of the Dogger Bank A offshore wind farm and are dubbed Dogger Bank South (DBS) East and Dogger Bank South (DBS) West.
RWE has also started with geophysical seabed surveys within the wind turbine array areas for its two new projects.
It appears that they have already got the leasing process started.
When Will Dogger Bank D And Dogger Bank South Be Operational?
Consider.
- In How Long Does It Take To Build An Offshore Wind Farm?, showed that a lot of offshore wind farms have gone from planning permission to first operation in six years.
- I don’t think that there will be planning permission problems on the Dogger Bank.
- The two wind farms are a continuation of Dogger Bank A, B and C and the Sofia wind farms.
- A lot of the construction, would be more of the same.
With average luck, I can see Dogger Bank D and Dogger Bank South in full production before the end of 2028.
The Salamander Project
The Salamander project may be a strange name for a proposed Scottish offshore wind farm, but that is what it is.
It is being developed by Ørsted and the Simply Blue Group.
There is a web site, which has this bold mission statement.
Helping To Unlock Scotland’s Floating Offshore Wind.
These paragraphs outline the project.
The Salamander project will utilise innovative and cutting-edge floating offshore wind technologies to produce zero-carbon electricity. The development aims to be a stepping stone to help Scotland and the UK to progress towards a net-zero future.
With a proposed 100 MW pre-commercial size project, the Salamander project which is located off Peterhead in the East coast of Scotland, is in an advanced planning stage. Salamander has a strong focus on supply chain development and will provide an opportunity for the local supply chain to gear up for commercial scale opportunities in Scotland, as well as de-risking floating wind technologies for the future commercial projects in Scotland and beyond. This will allow Scotland to maximise the financial benefit of its strong offshore wind resource and generate long term jobs for its local communities.
The project will contribute to the Scottish government’s target of 11 GW of installed offshore wind by 2030, as well as the UK government’s target of 5 GW of operational floating offshore wind by the same date.
There is also a video, which is very much a must-watch.
Floating offshore wind is a relatively new technology and will become the major generator of the world’s electricity within the next decade.
Note this phrase in the first paragraph.
The development aims to be a stepping stone to help Scotland and the UK to progress towards a net-zero future.
This philosophy is shared with other projects.
In DP Energy And Offshore Wind Farms In Ireland, I said this.
They are also developing the Gwynt Glas offshore wind farm in the UK sector of the Celtic Sea.
- In January 2022, EDF Renewables and DP Energy announced a Joint Venture partnership to combine their knowledge and
expertise, in order to participate in the leasing round to secure seabed rights to develop up to 1GW of FLOW in the Celtic Sea. - The wind farm is located between Pembroke and Cornwall.
The addition of Gwynt Glas will increase the total of floating offshore wind in the UK section of the Celtic Sea.
- 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
- Llŷr Wind – 100 MW Project – 25 miles offshore
- Llŷr Wind – 100 MW Project – 25 miles offshore
- Gwynt Glas – 1000 MW Project – 50 miles offshore
This makes a total of 2.2 GW, with investors from several countries.
It does seem that the Celtic Sea is becoming the next area of offshore wind around the British Isles to be developed.
These Celtic Sea wind farms include Erebus, which like Salamander is a 100 MW demonstration project.
Salamander And Erebus Compared
Consider.
- Both are 100 MW floating wind demonstration projects.
- Salamander and Erebus are 27 and 21 miles offshore respectively.
- Salamander and Erebus are close to the deepwater ports of Peterhead and Milford Haven.
- Both are described as stepping-stone projects.
- Both projects talk about developing supply chains.
- The developers of Salamander and Erebus include Ørsted and EDF Renewables respectively, who are both big beasts of the offshore wind industry.
Both wind farms are in areas, where the UK, Scottish and Welsh governments want to develop massive offshore wind farms, that will eventually total over 50 GW. I believe that Salamander and Erebus will indicate any problems, that will be likely to occur in the building of these massive offshore floating wind farms.
It is a very sensible plan and could lead to an energy rich future for the UK.
How Long Will It Take To Assemble A Floating Wind Turbine?
Each floating wind turbine requires these major components.
- A wind turbine, which in the Kincardine Wind Farm have a capacity of 9.5 MW, is obviously needed. Some proposed floating offshore wind farm are talking of turbines between 14 and 16 MW. These turbines will be very similar to onshore turbines.
- A float, usually made out of steel or possibly concrete. Various designs have been built or proposed. The Wikipedia entry for floating wind turbine gives several examples.
- The anchoring system to keep the float with its turbine in the desired position.
- The electrical system to connect the wind turbine to the offshore substation, which could also be floating.
Note that the designs for the float, anchoring and electrical systems will rely heavily on technology proven in the offshore oil and gas industry.
Principle Power are the designer of the WindFloat, which is one of the first floats to be used in floating offshore wind.
Their home page has a continuous full-screen video, that shows a WindFloat being assembled and towed out.
The video shows.
- The completed float being floated alongside a dock, which obviously has an appropriate water depth.
- The dock has a large crane.
- The turbine tower and then the blades being lifted into position and securely fixed.
- Finally, a tug tows the completed turbine/float assembly to its position in the wind farm.
This would appear to be an assembly operation, that could flow just like the production in any world-class vehicle factory.
- There would need to be just-in-time delivery of all components.
- The weather would need to be cooperative.
- Lighting might be needed to work in poorer light levels.
- This method of assembly would be turbine and float agnostic.
- Multiple shift working could be employed.
My project management involvement tells me, that it would not be unreasonable to assemble, at least one complete turbine and its float and accessories in a working day.
I can do a small calculation.
The average size of turbine is 15 MW.
One turbine is assembled per day.
There are 300 working days possible in a year with multiple shift working, ignoring Bank Holidays and bad weather.
Just one site could produce 4.5 GW of floating wind turbines per year.
How Many Production Sites Could There Be?
These are surely the best possibilities.
- Barrow
- Belfast
- Clyde
- Devon/Cornwall
- Forth Estuary
- Great Yarmouth
- Haven Ports
- Holyhead
- Humber
- Liverpool
- Milford Haven
- Peterhead
- Southampton Water
- South Wales
- Teesside
- Thames Estuary
I have named sixteen areas, that could be suitable for the assembly of floating wind turbines.
So let’s assume that eight will be developed. That could mean as much as 36 GW of capacity per year.
The Energy Density Of Floating Wind Farms
In ScotWind Offshore Wind Leasing Delivers Major Boost To Scotland’s Net Zero Aspirations, I summarised the latest round of Scotwind offshore wind leases.
- Six new fixed foundation wind farms will give a capacity of 9.7 GW in 3042 km² or about 3.2 MW per km².
- Ten new floating wind farms will give a capacity of 14.6 GW in 4193 km² or about 3.5 MW per km².
Returning to the earlier calculation, which says we could have the ability to create 36 GW of wind turbines per year, with 15 MW turbines, this means with a generating density of 3.5 MW per km², the 36 GW would take up around a hundred kilometre square of sea.
Conclusion
We will become Europe’s powerhouse.
