Seabed Power Grid To Link North Sea Wind Turbines
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
A vast power grid on the seabed of the central North Sea is being planned as part of a £20bn project to power oil and gas platforms with green electricity.
Points in the article include.
- There could be more than 400 offshore turbines.
- If they were 15 MW turbines, that would be at least 6 GW.
- The plan could involve 10,000 jobs, many of which could be in the supply chain in Scotland.
- The plan is for three connected large sea areas in the central North Sea covering nearly 400 square miles.
- Infrastructure could be in place by 2028.
- Scotland was among the most investable countries in the world for floating wind farms.
- Partners include experienced companies like NOV, Siemens Gamesa, Siemens Energy, DEME and Worley.
- Nearly a third of the world’s current order pipeline for floating wind is destined for Scottish waters.
In Cerulean Winds Is A Different Type Of Wind Energy Company, I said, the project is privately-funded. and will need no government subsidy .
This article on offshoreWIND.biz is entitled Cerulean North Sea Renewables Grid To Power Oil & Gas Platforms With Floating Wind finishes with this paragraph.
Cerulean has agreed on an approach with its industrial partners early to de-risk the project in the same way other large-scale infrastructure developments are initiated, the company said. In total, the three wind farms could contribute over GBP 12 billion GVA to the UK’s economy.
Do you believe in magic money trees?
The Original Cerulean Press Release
This press release on the Cerulean Wind web site, gives more details.
Read it and you might get some measure of the ambition of the company.
Questions And Thoughts
In Cerulean Winds Is A Different Type Of Wind Energy Company, I answer a few questions at the end of the post, and come to this conclusion.
It looks like Cerulean Winds are a very different energy company.
If you have any more questions, put them in the comments and I’ll answer them, as best as I can in the related post.
Three Players Pursuing Floating Offshore Wind Opportunities At Barents Sea Oil Field
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Norwegian oil and gas company Vår Energi has entered into a collaboration with a consortium consisting of Odfjell Oceanwind and Source Galileo to explore opportunities for floating offshore wind through a pilot project at a field located in the Barents Sea off Norway.
The article mentions the Goliat oil field, which is located 85 kilometres (53 mi) northwest of Hammerfest.
This Google Map shows the location of Hammerfest.
Note.
- Hammerfest is marked by the red arrow.
- Hammerfest is the northernmost town in the world with more than 10,000 inhabitants.
- The furthest North, I’ve been in Europe is to Trondheim, which is in the South-West corner of the map.
- To the East of Hammerfest Norway and Russia have a common border and beyond that is the Russian port of Murmansk.
Many years ago, my first visits to Ipswich Town were courtesy of the Official Receiver for Ipswich; John Richardson, who was my parents’ next door neighbour in Felixstowe.
John was an interesting guy, who during the Second World War had been on the Arctic convoys to Murmansk and Archangel. The Wikipedia entry for Arctic Convoys Of World War Two, gives some details.
His descriptions of the weather in the area were horrendous and it makes me wonder why the Norwegians want to extract oil in those conditions. And now generate wind power.
This is the first sentence of the article.
Vår Energi disclosed the deal on Wednesday, 26 April 2023, explaining that the project, called GoliatVind, was a pilot project to demonstrate new, Norwegian offshore wind technology.
So is it all about new technology?
Gazelle Wind Power Unveils Third Generation Floating Offshore Wind Platform Technology
The title of this post, is the same as that, of this press release from Gazelle Wind Power.
There is a visualisation in the press release and it looks very different.
This is the first paragraph.
Gazelle Wind Power (Gazelle), the developer of a modular floating offshore wind platform, is unveiling third generation technology this week at WindEurope 2023 in Copenhagen, Denmark. The company’s enhanced design further refines Gazelle’s solution to address the primary challenges facing the offshore wind industry—such as cost, supply chain bottlenecks, and sustainability—by providing a lightweight, cheaper design that minimizes the impact on fragile marine environments while using existing port infrastructure.
It looks like they’ve set themselves a tough set of objectives.
These are a few points from the press release.
- A one-gigawatt offshore wind farm using Gazelle’s solution would save 71 kt of steel and reduce emissions of approximately 100 kt of carbon dioxide.
- The company’s platform can be quickly and simply installed at project sites because it requires no specialist cranes or vessels.
- The platform’s unique geometry provides reduced draft in port, which means it floats higher in the water enabling the use of shallow ports.
- Through industrial innovation, the platform components can be adjusted to accommodate all forecasted offshore wind turbine sizes, including the current 15MW or greater capacities.
- Our platform can be produced anywhere in the world, supporting job creation through regionalized manufacturing.
When I look back on how offshore oil and gas platforms changed in the North Sea over a couple of decades, I’m not surprised to see this innovative design.
I wish the company the best of luck. But I don’t think they’ll need it!
Norway Has Room For 338 GW Of Offshore Wind, New Analysis Finds
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Norway has the potential to develop up to 338 GW of offshore wind in areas with a low level of conflict, according to a new analysis performed by Multiconsult and commissioned by the industry organisation Norwegian Offshore Wind, Equinor, Source Galileo, Hafslund and Deep Wind Offshore.
These two paragraphs are the main findings of the report.
The report, issued on 14 April, maps 28 areas as suitable for floating wind and 18 areas for fixed-bottom offshore wind, estimating the total potential installed capacity to be 241 GW at 5 MW/km2 and 338 GW at 7 MW/km2.
Of this, floating wind could account for 156 GW and up to 219 GW, while fixed-bottom capacity is between 85 GW and 119 GW.
So how does that figure look for the UK?
Consider.
- The UK has an Exclusive Economic Zone of 773,676 sq. kilometres.
- But if you include overseas territories, the UK’s area is 6,805,586 sq. kilometres and is the fifth largest in the world.
- Norway has an Exclusive Economic Zone of 2,385,178 sq. kilometres.
So taking the 338 GW figure for Norway and ignoring overseas territories, we could generate 109.6 GW.
Windeed’s Floater Solution Gets Bureau Veritas Nod
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Bureau Veritas has granted Approval in Principle (AiP) to Sweden-based Windeed for its low-weight and low-acceleration floater solution for offshore wind turbines.
These three paragraphs fill in more details.
The AiP is a significant milestone in the development of Windeed’s technology, which could offer competitive prices and lower levelised cost of energy (LCOE) compared to other solutions on the market due to its industrialised manufacturing process, the developer said.
Bureau Veritas provided testing and assessment to ensure the solution is safe, reliable, and ready for deployment.
The approval in principle is a testament to the quality and innovation of the company’s technology.
I have been waiting some months for a new more efficient float for offshore wind turbines and then Gazelle Power Systems and Windeed turn up with designs on the same day.
Pictures of Gazelle’s design are available on their web site, but Windeed’s web site is text only, although it does say this.
Our purpose is to provide superior technology and industrialization of floating offshore wind power, lowering costs and environmental impact, to meet the need of more and clean energy.
I wouldn’t be surprised to see other designs!
Irish Floating Wind Tech Developer Unveils Pilot Project In Portugal
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Dublin-based floating wind technology company Gazelle Wind Power (Gazelle) has partnered with the Portuguese renewable energy developer WAM Horizon to accelerate the development of a pilot project in Aguçadoura, Portugal, which will use Gazelle’s floating wind platform.
And this is the first paragraph.
Within the partnership, WAM will provide Gazelle with strategic advisory to implement the pilot project.
There is also a picture, which does not look like any other float for a wind turbine, that I’ve seen.
Gazelle Wind Power’s home page, has a series of pictures and an explanation of how it works.
The web site claims the technology is Light, Agile and Fast and gives a few details in this paragraph.
Introducing Gazelle’s hybrid attenuated mooring platform, an evolutionary step-change in the design of floating platforms. Lighter, smaller and more agile than current designs, the Gazelle delivers unmatched stability and capacity. Moreover, our design benefits from modularisation, time-tested manufacturing processes, and can easily be assembled at port facilities worldwide.
From my experience of modelling floating structures in the 1970s, I believe that there a lot more permutations and combinations of components, that will work as floats for wind turbines.
Gazelle Wind Power’s design, is one of the first of a new generation of designs.
If anybody comes up with an unusual design and needs someone to criticise or model its floating behaviour, I’d be happy to help.
UK Launches GBP 160 Million Floating Wind Funding Round, Industry Not Satisfied With Investment
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 announced that up to GBP 160 million in grant funding will be made available for certain investments for the floating offshore wind sector
These three paragraphs outline the scheme,
The Department of Energy Security and Net Zero (DESNZ) has established the Floating Offshore Wind Manufacturing Investment Scheme (FLOWMIS) to distribute GBP 160 million in funding to support critical port infrastructure that could enable the delivery of floating offshore wind.
Through this scheme, the government hopes to enable the delivery of the country’s 5 GW 2030 deployment ambition by securing additional suitable port capacity necessary to scale up and accelerate floating offshore wind deployment in the UK, as well as to increase capability in the UK floating wind supply chain, drive cost reduction, and the commercialisation of floating offshore wind technology.
In addition, the government hopes that this scheme will deliver industrial growth and associated regional economic and social benefits (for example, quality jobs and increased GVA).
Note.
- The scheme is called FLOWMIS.
- It seems to be geared to improve port infrastructure.
- It looks like some of these projects will be needed to support ScotWind and INTOG.
- This page on the Government web site, gives the latest state of FLOWMIS.
FLOWMIS could bring forward some interesting projects.
13 Offshore Wind Projects Selected In World’s First Innovation And Targeted Oil & Gas Leasing Round
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Crown Estate Scotland has selected 13 out of a total of 19 applications with a combined capacity of around 5.5 GW in the world’s first leasing round designed to enable offshore wind energy to directly supply offshore oil and gas platforms.
This paragraph outlines INTOG (Innovation and Targeted Oil & Gas) and its objectives.
INTOG, which has been designed in response to demand from government and industry to help achieve the targets of the North Sea Transition Sector Deal through decarbonising North Sea oil and gas operations, is also expected to further stimulate innovation in Scotland’s offshore wind sector, create additional supply chain opportunity, assist companies to enter the renewable energy market, and support net-zero ambitions.
This is undoubtedly the most important news of the day.
- When complete it will generate 5416 MW of electricity.
- 4068 MW will be used primarily to decarbonise oil and gas platforms with surplus electricity going to the grid.
- The amount of carbon dioxide released by oil and gas platforms in the North Sea will be reduced.
- The gas saved by decarbonising oil and gas platforms, will be transported to the shore and used in the UK gas grid.
- 449 MW will be generated in innovative ways in small wind farms, with a capacity of less than 100 MW.
One of the benefits of INTOG is that the UK will be able to reduce gas imports, which must increase energy security.
This map from this document from the Crown Estate Scotland, shows the INTOG wind farms.
This is a list of the farms.
- 1 – Bluefloat Energy/Renantis Partnership – Innovation – Commercial – 99.45 MW
- 2 – Bluefloat Energy/Renantis Partnership – Innovation – Supply Chain – 99.45 MW
- 3 – Simply Blue Energy (Scotland) – Innovation – Supply Chain – 100 MW
- 4 – BP Alternative Energy Investments – Innovation – New Markets – 50 MW
- 5 – ESB Asset Development – Innovation – Cost Reduction – 100 MW
- 6 – Floatation Energy – Targeted Oil & Gas – 560 MW
- 7 – Cerulean Winds – Targeted Oil & Gas – 1008 MW
- 8 – Harbour Energy – Targeted Oil & Gas – 15 MW
- 9 – Cerulean Winds – Targeted Oil & Gas – 1008 MW
- 10 – Cerulean Winds – Targeted Oil & Gas – 1008 MW
- 11 – Floatation Energy – Targeted Oil & Gas – 1350 MW
- 12 – TotalEnergies – Targeted Oil & Gas – 3 MW
- 13 – Harbour Energy – Targeted Oil & Gas – 15 MW
Note.
- These total up to 5.42 GW.
- The five Innovation sites seem to be as close to the coast as is possible.
- I thought some Innovation sites would be closer, so supply difficult to reach communities, but they aren’t.
- Floatation Energy and Cerulean Winds seemed to have bagged the lion’s share of the Targeted Oil & Gas.
- Sites 6 and 7 sit either side of a square area, where Targeted Oil & Gas will be considered. Is that area, the cluster of oil and gas facilities around Forties Unity, shown on the map in this page on the BP web site?
- Harbour Energy have secured two 15 MW sites for Targeted Oil & Gas.
These are my thoughts on the various companies.
Bluefloat Energy
Bluefloat Energy has posted this press release on their web site, which is entitled Bluefloat Energy | Renantis Partnership Bid Success For Two 99mw Innovation Projects In Crown Estate Scotland’s INTOG Process.
The press release starts with these three bullet points.
- BlueFloat Energy | Renantis Partnership offered exclusivity rights to develop its Sinclair and Scaraben floating wind projects north of Fraserburgh – leveraging synergies via its 900MW Broadshore project.
- The projects seek to trial innovative floating wind technology solutions, kick-starting supply chain growth and job creation in Scotland and providing a ‘stepping-stone’ to the partnership’s ScotWind projects.
- Bid proposals include the intention to develop a scalable community benefit model – creating a potential blueprint for floating offshore wind in Scotland.
The first three paragraphs expand the bullet points.
The BlueFloat Energy and Renantis Partnership has been offered seabed exclusivity rights to develop two 99MW projects under the innovation arm of Crown Estate Scotland’s INTOG (Innovation and Targeted Oil & Gas) auction process. The auction saw ten projects bid to bring forward the development of small-scale innovation projects.
The Sinclair and Scaraben projects, located north of Fraserburgh and adjacent to the Partnership’s 900MW Broadshore project, seek to trial innovative foundation technologies, associated fabrication works and mooring systems with a view to maximising opportunities for the Scottish supply chain, driving local investment and job creation.
A key element of the bid proposals is the opportunity to test and adapt a community benefit model, governed independently, and directed by the communities in which the schemes will operate, through collaboration with our supply chain and project partners. The model could create a blueprint, shaping the future of community benefit from floating offshore wind throughout the whole of Scotland. This builds on Renantis’ successful track record of deploying similar schemes via its onshore wind farms in Scotland.
Note.
- Companies called Sinclair Offshore Wind Farm and Scaraben Offshore Wind Farm were registered a few months ago in Inverness.
- I couldn’t find the websites, so I suspect they’re still being created.
- These two projects appear to be pathfinders for the 900 MW Broadshore project, with regards to the supply chain and community involvement.
It certainly looks like the partnership are going about the development of these two projects in a professional manner.
BP Alternative Energy Investments
There has been no press release from BP as I write this, so I will have to deduce what BP are planning.
This map from this document from the Crown Estate Scotland, shows the Southern INTOG wind farms.
Note.
- Site 4 is the site of BP Alternative Energy Investments’s proposed wind farm.
- Sites 6 and 7 could be either side of the cluster of platforms around Forties Unity.
Consider.
- In the wider picture of wind in the North Sea, BP’s proposed 50 MW wind farm is a miniscule one. SSE Renewables’s Dogger Bank wind farm is over a hundred times as large.
- A cable to the shore and substation for just one 50 MW wind farm would surely be expensive.
- BP Alternative Energy Investments are also developing a 2.9 GW wind farm some sixty miles to the South.
- It would probably be bad financial planning to put large and small wind farms so close together.
For these are other reasons, I believe that there is no reason to believe that the proposed 50 MW wind farm is a traditional wind farm.
But if I’m right about sites 6 and 7 indicating the location the position of Forties Unity, it might open up other possibilities.
This document from INEOS, who own the Forties Pipeline System, explains how the pipeline works.
The Forties Pipeline System (FPS) is an integrated oil and gas transportation and processing system. It is owned and operated by INEOS and utilises more than 500 miles of pipeline to smoothly transport crude oil and gas from more than 80 offshore fields for processing at the Kinneil Terminal. At Kinneil the oil and gas are separated, with the oil returned as Forties Blend to customers at Hound Point or pumped to the Petroineos refinery at Grangemouth.
At the same time the gas goes to our LPG export facilities or is supplied to the INEOS petrochemical plant. FPS transports around 40% of the UK’s oil production supply and brings over 400,000 barrels ashore every day.
In Can The UK Have A Capacity To Create Five GW Of Green Hydrogen?, I said the following.
Ryze Hydrogen are building the Herne Bay electrolyser.
- It will consume 23 MW of solar and wind power.
- It will produce ten tonnes of hydrogen per day.
The electrolyser will consume 552 MWh to produce ten tonnes of hydrogen, so creating one tonne of hydrogen needs 55.2 MWh of electricity.
If BP were to pair the wind farm with a 50 MW electrolyser it will produce 21.7 tonnes of hydrogen per day.
Could it be brought to the shore, by linking it by a pipeline to Forties Unity and then using the Forties Pipeline System?
As the category on site 4, is New Markets, are BP and INEOS investigating new markets for hydrogen and hydrogen blends?
- Some of the latest electrolysers don’t need pure water and can use sea water. This makes them more affordable.
- Do BP and/or INEOS have the capability to extract the hydrogen as it passes through the Cruden Bay terminal, to provide the hydrogen for Aberdeen’s buses and other users?
- INEOS and BP probably have some of the best oil and gas engineers in the world.
- How many other places in the world have an offshore oil or gas field set in a windy sea, where floating wind- turbine/electrolysers could generate hydrogen and send it ashore in an existing pipeline?
- Several of these offshore oil and gas fields and the pipelines could even be owned by BP or its associates.
- Remember that hydrogen is the lightest element, so I suspect it could be separated out by using this property.
This BP site, is to me, one of the most interesting of the successful bids.
- BP probably have a large collection of bonkers ideas, that have been suggested during their long involvement with offshore oil and gas.
- Some ideas could be even suggested by employees, whose fathers worked for BP fifty years ago. I’ve met a few BP employees, whose father also did.
- Will the wind farm, be a floating electrolyser at the centre of a cluster of a few large floating turbines?
- Will each turbine have its own electrolyser and the substation only handle hydrogen?
- Will the floating electrolyser have hydrogen storage?
- Have BP got a floating or semi-submersible platform, that could either go to the breakers or be repurposed as the floating electrolyser?
- Repurposing a previous platform, would make all the right noises.
So many possibilities and so far, no clues as to what will be built have been given.

Further Thoughts On BP’s Successful INTOG Bid
Cerulean Winds
In What Is INTOG?, I said this about Cerulean Winds.
Cerulean sounds like it could be a sea monster, but it is a shade of blue.
This article on offshoreWind.biz is entitled Cerulean Reveals 6 GW Floating Offshore Wind Bid Under INTOG Leasing Round.
These are the two introductory paragraphs.
Green energy infrastructure developer Cerulean Winds has revealed it will bid for four seabed lease sites with a combined capacity of 6 GW of floating wind to decarbonise the UK’s oil and gas sector under Crown Estate Scotland’s Innovation and Targeted Oil and Gas (INTOG) leasing round.
This scale will remove more emissions quickly, keep costs lower for platform operators and provide the anchor for large-scale North-South offshore transmission, Cerulean Winds said.
Note.
-
- It is privately-funded project, that needs no government subsidy and will cost £30 billion.
- It looks like each site will be a hundred turbines.
- If they’re the same, they could be 1.5 GW each.
- Each site will need £7.5 billion of investment. So it looks like Cerulean have access to a similar magic money tree as Kwasi Kwarteng.
Effectively, they’re building four 1.5 GW power stations in the seas around us to power a large proportion of the oil and gas rigs.
For more on Cerulean Winds’s massive project see Cerulean Winds Is A Different Type Of Wind Energy Company.
So does it mean, that instead of 6 GW, they were only successful at three sites and the other or others were in the six unsuccessful applications?
There is a press release on the Cerulean Winds web site, which is entitled Cerulean Winds Wins Bid For Three INTOG Floating Wind Sites, where this is said.
Cerulean Winds and Frontier Power International have been awarded three lease options for the Central North Sea in the highly competitive INTOG leasing round, the results of which were announced by Crown Estate Scotland today.
The sites, in the Central North Sea, will enable the green infrastructure developer and its partners to develop large floating offshore windfarms to decarbonise oil and gas assets. The scale of the development will enable a UK wide offshore transmission system, that can offer green energy to offshore assets in any location and create a beneficial export opportunity.
Nothing about unsuccessful applications was said.
This map from this document from the Crown Estate Scotland, shows the Southern INTOG wind farms.
Note.
- Sites 7, 9 and 10 are Cerulean’s sites.
- Sites 6 and 11 are Floatation Energy’s sites.
- Site 4 is BP Alternative Energy Investments’s Innovation site.
- Sites 8, 12 and 13 are much smaller sites.
It looks like Cerulean and Floatation Energy are well-placed to power a sizeable proportion of the platforms in the area.
ESB Asset Development
ESB Asset Development appear to be a subsidiary of ESB Group.
The ESB Group is described like this in the first paragraph of their Wikipedia entry.
The Electricity Supply Board is a state owned (95%; the rest are owned by employees) electricity company operating in the Republic of Ireland. While historically a monopoly, the ESB now operates as a commercial semi-state concern in a “liberalised” and competitive market. It is a statutory corporation whose members are appointed by the Government of Ireland.
This press release, is entitled ESB Offered Exclusive Rights To Develop Innovative 100MW Floating Offshore Wind Project In The Malin Sea.
These two paragraphs outline the project.
ESB today welcomes the outcome of Crown Estate Scotland’s latest seabed leasing process which has resulted in the offer of exclusive development rights to ESB for a 100MW floating wind project in Scottish waters off the north coast of Northern Ireland. The successful project, Malin Sea Wind, is a collaborative bid between ESB and leading technology developers Dublin Offshore Technology and Belfast-based CATAGEN. The outcome underscores ESB’s growing capabilities and expanding presence in the offshore wind industry.
The Innovation and Targeted Oil and Gas (INTOG) seabed leasing process, run by Crown Estate Scotland, aims to drive cost reduction in the offshore wind sector by enabling the deployment of new and innovative technologies, and to harness wind energy to decarbonize the oil and gas sector. Malin Sea Wind aims to support the reduction of floating offshore wind costs by demonstrating Dublin Offshore’s patented load-reduction technology. Furthermore, the project will support decarbonisation of the aviation sector by powering sustainable aviation fuel (SAF) production technology currently under development by net-zero technology specialists, CATAGEN.
Note.
- I’ve just looked at the Technology page of the Dublin Offshore Technology web site.
- In the 1970s, I built large numbers of mathematical models of steel, concrete and water cylinders in my work with a Cambridge University spin-out called Balaena Structures.
- I believe, that an experienced mathematically modeller could simulate this clever system.
That would prove if it works or not!
This Google Map shows the Malin Sea.
Note.
- Malin Head is marked by the red arrows on the Northern Irish coast.
- The most Westerly Scottish island is Islay and the most Easterly is the Isle of Arran.
- Between the two islands is the Kintyre peninsula.
- Portrush can be picked out on the Northern Irish coast.
By overlaying the two maps, I suspect the centroid of the wind farm will be North of Portrush about a few miles North of the Southern end of Arran.
I suspect that if all goes well, there could be a lot of floating wind turbines in the area.
This Google Map shows the River Foyle estuary and Foyle Port to the North-East of Londonderry/Derry.
Note.
- Coolkeeragh ESB and Lisahally biomas power station on the South bank of the River Foyle.
- Lisahally biomas power station has a capacity of 16 MW.
- There appears to be a large substation at Coolkeeragh ESB.
- A tanker of some sort seems to be discharging.
Until told, I’ve guessed wrong, it looks to me like Coolkeeragh ESB could be the destination for the electricity generated by Malin Sea Wind. Given that this project’s aim is cost reduction, a 100 MW wind farm could make a difference.
In addition could Foyle Port be used to assemble and maintain the floating turbines?
Floatation Energy
Floatation Energy have posted this press release on their web site, which is entitled Flotation Energy and Vårgrønn Awarded Exclusivity To Develop Up To 1.9 GW Of Floating Offshore Wind In Scotland.
The first part of the press release, has a graphic.
It shows how their proposed system will work.
- A floating wind farm will be placed between the shore and oil and gas platforms to be decarbonised.
- The wind farm will be connected to the shore by means of a bi-directional cable, so that the wind farm can export electricity to the grid and when the wind isn’t blowing the grid can power the platforms.
- A cable between the wind farm and the platforms completes the system.
It is a simple system, where all elements have been built many times.
Floatation Energy must have been fairly confident that their bids would be successful as they have already named the farms and set up web sites.
- Site 6 – Green Volt – 560 MW
- Site 11 – Cenos – 1350 MW
The websites are very informative.
The Timeline for 2019-2021 on the Green Volt web site describes the describes the progress so far on the project.
2019 – As construction of the Kindardine offshore floating wind farm kicks off, Flotation Energy identifies the Buzzard oil facility (a relatively new oil and gas platform with a long field life and high electrical load) as the optimal starting point for a significant contribution to the North Sea Transition Deal – the process of replacing large scale, inefficient gas-fired power generation with renewable electricity from offshore wind.
2020 – Flotation Energy begins environmental surveys on the Ettrick/Blackbird oil field, a redundant site nearby Buzzard, which is in the process of decommissioning. The “brownfield” site is confirmed as an exceptional opportunity to create an offshore floating wind farm, with water depths of 90-100m and high quality wind resource.
2021 – Flotation Energy works with regulators to understand the potential for project “Green Volt” to decarbonise offshore power generation for Buzzard. Flotation Energy completes and submits an Environmental Scoping report to Marine Scotland, reaching the first major milestone in the Marine Consent process. Crown Estate Scotland announces a new leasing round for Innovation and Targeted Oil and Gas Decarbonisation (INTOG).
On a section on the Cenos web site, there is a section called Efficient Grid Connection, where this is said.
The power generated by the wind turbines will be Alternating Current (AC) and routed to a substation platform. AC power will be exported to the oil and gas platforms.
For efficient export to the UK grid, the substation platform will include a converter station to change the AC power to Direct Current (DC) before the power is transported to shore. This is due to transporting AC power over long distances leading to much of the power being lost.
Cenos is working in partnership with the consented NorthConnect interconnector project, to utilise their DC cable routing where possible. Cenos will also use the NorthConnect onshore converter station planned for Fourfields near Boddam, which then has an agreed link into the Peterhead Substation. This collaboration minimises the need to construct additional infrastructure for the Cenos project.
That all sounds very practical.
Note.
- Floatation Energy delivered the Kincardine offshore floating wind farm.
- Both wind farms appear to use the same shore substation.
- Buzzard oil field is being expanded, so it could be an even more excellent oil field to decarbonise.
- NorthConnect is a bit of an on-off project.
Floatation Energy seem to have made a very professional start to the delivery of their two wind farms.
Harbour Energy
The Wikipedia entry for Harbour Energy describes the company like this.
Harbour Energy plc is an independent oil and gas company based in Edinburgh, Scotland. It is the United Kingdom’s largest independent oil and gas business. It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index.
But if you look at news items and the share price of the company, things could look better for Harbour Energy.
On their map of UK operations, I can count nearly twenty oil and gas fields.
As they have other oil and gas fields around the world, decarbonisation of their offshore operations could increase production by a few percent and substantially cut their carbon emissions.
That is a philosophy that could be good for profits and ultimately the share price.
So has the company gone for a very simple approach of two identical floating wind turbines?
They have been successful in obtaining leases for sites 8 and 13.
- Both have a capacity of 15 MW, so are the farms a single 15 MW wind turbine?
- I think this is likely, unless it is decided to opt for say a 16 MW turbine.
- Or even a smaller one, if the platform is in a bad place for wind.
- The wind turbine would be parked by the platform to be decarbonised and connected up, to a simple substation on the platform.
- I would recommend a battery on the platform, so that if the wind wasn’t blowing, power was still supplied to the platform.
- There would be no need for any cable between shore and wind farm and the only substation, would be a relatively simple one with a battery on the platform.
It could be a very efficient way of decarbonising a large number of platforms.
Once Harbour Energy have proved the concept, I could build a simple mathematical model in Excel, to work out any change in profitability and carbon emissions for a particular oil or gas platform.
Who Is Britannia Ltd?
In this document from the Crown Estate Scotland, there is a section that gives the partners in each project.
Listed for site 8 are Chrysaor (U.K.) and Britannia Limited and for site 13 is Chryasaor Petroleum Company UK Limited.
This page on the Harbour Energy web site gives the history of Chrysaor and Harbour Energy.
This is the heading.
Chrysaor was founded in 2007 with the purpose of applying development and commercial skills to oil and gas assets and to realise their value safely.
This is the history.
The Group grew rapidly over the years through a series of acquisitions. With backing from Harbour Energy – an investment vehicle formed by EIG Global Energy Partners – Chrysaor acquired significant asset packages in the UK North Sea from Shell (2017) and ConocoPhillips (2019) to become the UK’s largest producer of hydrocarbons.
In 2021, Chrysaor merged with Premier Oil to become Harbour Energy plc.
So that explains the use of the Chrysaor name or Chryasaor as someone misspelt it on the Crown Estate Scotland document.
I asked myself, if Britannia Ltd. could be a technology company, so I checked them out. The only company, I could find was a former investment trust, that was dissolved over ten years ago.
But Britannia is an oil and gas field in the North Sea, which is partially owned by Harbour Energy. It has a page on Harbour Enerrgy’s web site, which is entitled Greater Britannia Area.
This is said about the Britannia field.
Britannia in Block 16/26 of the UK central North Sea sits approximately 210-kilometres north east of Aberdeen. The complex consists of a drilling, production and accommodation platform, a long-term compression module of mono-column design and a 90-metre bridge connected to a production and utilities platform. Britannia is one of the largest natural gas and condensate fields in the North Sea. Commercial production began in 1998. Condensate is delivered through the Forties Pipeline to the oil stabilisation and processing plant at Kerse of Kinneil near Grangemouth and natural gas is transported through a dedicated Britannia pipeline to the Scottish Area Gas Evacuation (SAGE) facility at St Fergus.
Looking at the maps on the Crown Estate Scotland, Harbour Energy and others, it looks like site 8 could be close to the
Greater Britannia Area or even the Britannia field itself.
Simply Blue Energy
Simply Blue Energy are developing the 100 MW Salamander wind farm.
I wrote about this project in The Salamander Project.
Did it get chosen, as it was a project, where the design was at an advanced stage?
TotalEnergies
I wouldn’t be surprised to find out that TotalEnergies have gone a very similar route to Harbour Energy, but they are trying it out with a 3 MW turbine.
Conclusion
They are an excellent group of good ideas and let’s hope that they make others think in better and move innovative ways.
Politics will never save the world, but engineering and science just might!
BW Ideol In Talks To Raise EUR 40 Million For Floating Wind Development
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Norway-headquartered BW Ideol and French state-owned investment company ADEME Investissement have agreed to enter into exclusive negotiations for EUR 40 million in funding by ADEME Investissement for BW Ideol’s project development activities.
The rest of the post is all about the clever, but I suspect legal ways, that the € 40 million is raised.
When I needed any advice in that area, I used to consult my late friend the banker; David, who is mentioned in Diversifying A US$200 billion Market: The Alternatives To Li-ion Batteries For Grid-Scale Energy Storage.
When he needed computing advice, that is another story.
RWE Underlines Commitment To Floating Offshore Wind In The Celtic Sea Through New ‘Vision’ Document
The title of this post, is the same as that of this press release from RWE.
These are the three bullet points.
- Offshore floating wind in the Celtic Sea could unlock 3,000 jobs and £682 million in supply chain opportunities by 2030
- RWE is targeting the development at least 1GW of floating wind in the region
- Using experience from demonstrator projects and partnerships with local supply chain to strengthen ambitions
These opening three paragraphs outline more of RWE’s vision.
RWE, the world’s second largest offshore wind player and largest generator of clean power in Wales, has unveiled its vision for the future of floating offshore wind in the Celtic Sea region and the opportunities it presents from new large-scale, commercial projects. Entitled “RWE’s Vision for the Celtic Sea”, the document was unveiled during day one of the Marine Energy Wales conference, in Swansea, where RWE is the Platinum Sponsor.
RWE sees floating wind technology as the next frontier in the development of the offshore wind sector, and which could potentially unlock a multi-billion pound opportunity for the broader Celtic Sea region and the UK.
Studies anticipate the first GW of floating wind to be developed in the Celtic Sea could potentially deliver around 3,000 jobs and £682 million in supply chain opportunities for Wales and the south west of England. Against this backdrop, it’s anticipated the technology could unlock a resurgence in Welsh industry, helping to decarbonise industry and transport, spur on academic innovation, and spearhead the growth of a new, highly skilled workforce.
Reading further down, there are these statements.
- RWE will be bidding in the upcoming Celtic Sea auction with the aim of securing at least 1 gigawatt (GW) of installed capacity, to be developed throughout the 2020’s.
- The Celtic Sea region is pivotal to RWE’s ‘Growing Green’ strategy in the UK, where we expect to invest £15 billion in clean energy infrastructure by 2030.
- A cooperation agreement with Tata SteelUK to understand and explore the production of steel components that could be used in high-tech floating wind foundations and structures for projects in the Celtic Sea.
- The company has also signed agreements with ABP Port Talbot, the Port of Milford Haven and Marine Power Systems of Swansea, to explore opportunities for building the supply chain for floating wind.
- RWE is the largest power producer and renewable energy generator in Wales with more than 3GW of energy across 11 sites.
- If successful in the leasing round, RWE’s Celtic Sea projects will also play a key role in the development of RWE’s Pembroke Net Zero Centre, as well as decarbonizing wider industrial processes and transportation across South Wales.
It looks like RWE are very serious about the Celtic Sea and Pembrokeshire.
Pembroke Net Zero Centre
The Pembroke Net Zero Centre looks to be a powerful beast.
It will be located at the 2200 MW Pembroke power station, which is the largest gas-fired power station in Europe.
These are the first two paragraphs on its web page.
RWE is a world leader in renewables, a market leader in the development of offshore wind and a key driver of the global energy transition. In turn, Pembroke is looking to continue its transformation as part of a decarbonisation hub under the title of the PNZC, linking-up with new innovative technologies needed for a low carbon future, including hydrogen production, Carbon Capture and Storage and floating offshore wind.
The PNZC will bring together all areas of the company’s decarbonisation expertise, including innovation, offshore wind, power engineering, trading and the development/operation of highly technical plants.
The page also talks of burning hydrogen in the power station and an initial 100-300 MW ‘pathfinder’ electrolyser on the Pembroke site.
Conclusion
In some ways, RWE are following a similar philosophy in the area, to that being pursued by SSE at Keadby on Humberside.
As The Crown Estate is talking of 4 GW in the Celtic Sea, it looks like RWE are positioning Pembroke to be the backup, when the wind doesn’t blow.
