Aker Solutions To Pilot Floating-Wind Power Hub
The title of this post, is the same as that of this press release from Aker Solutions.
This is the sub-heading.
Aker Solutions to pilot world’s first subsea power distribution system for floating offshore wind at Norway´s METCentre
These four paragraphs describe the system and explain how it works.
Note.
Aker Solutions has signed a front-end engineering and design (FEED) contract with the Marine Energy Test Centre (METCentre) in Norway to pilot new subsea power system technology which has the potential to significantly reduce the costs and complexity of offshore wind farms.
The project will see Aker Solutions provide new power transmission technology, Subsea Collector, for the METCentre’s offshore wind test area which today consists of two floating offshore wind turbines located 10 kilometers off the southwestern coast of Karmøy, Norway. The test area will expand to seven floating offshore wind turbines from 2026.
Subsea Collector provides an alternative solution to connect multiple wind turbines electrically in a star configuration instead of the traditional daisy chain pattern, allowing for more flexibility in offshore wind farm architecture and construction. The design also allows for reduced cable length per turbine and park, as well as less vessel time and installation costs. Initial findings support total cost savings on a 1GW floating wind farm of up to 10 percent.
The main component parts of the Subsea Collector comprise a 66kV wet mate connection system provided by Benestad and subsea switchgear with supervisory control and data acquisition by subsea power and automation alliance partner, ABB. Installation will be carried out by Windstaller Alliance, an alliance between Aker Solutions, DeepOcean and Solstad Offshore. Aker Solutions will also provide the static export cable to shore.
Total cost savings of ten percent on any large project are not to be sneezed at.
I also feel that this sort of architecture will be ideal for a test centre, where configurations are probably changed more often.
Is This Better News For Offshore Wind Farm Developers?
Two months ago this article on offshoreWIND.biz was published, which was entitled Offshore Wind Developers Take A Pass On UK’s Fifth CfD Round As Maximum Bid Price Was Too Low.
This was the sub-heading.
The UK government has awarded 3.7 GW of renewable energy projects with Contracts for Difference (CfDs) in its fifth allocation round. Among the 95 new projects that secured CfDs are onshore wind, solar and tidal energy developments – and not a single megawatt of offshore wind.
These are the first three paragraphs of the article.
According to the government, the global rise in inflation and the impact on supply chains presented challenges for projects participating in this round. The government also noted that similar results have been seen in countries such as Germany and Spain.
The industry does not disagree, however, multiple players have voiced their disappointment that the government had not taken these pressures into account for this round and emphasised that the UK’s goal of having 50 GW of offshore wind and 5 GW of floating wind could now be jeopardised.
Last year, the UK awarded CfDs to 7 GW of offshore wind projects alone.
Today, articles with these titles and sub-headings were published on offshoreWIND.biz.
- 50 Developers Express Interest To Build Wind Farms Offshore Portugal
Fifty entities, including individual companies and consortia, from more than ten countries have submitted their expressions of interest to develop offshore wind projects in Portugal as the country prepares for its first auction.
2. Fugro To Survey Site For Lithuania’s First Offshore Wind Farm
Ignitis Renewables has awarded Fugro a contract to conduct a geophysical survey at Lithuania’s first offshore wind farm site.
3. Norway’s Offshore Wind Tender Attracts Seven Applications
Norway’s Ministry of Petroleum and Energy has received seven applications to participate in the tender for the Southern North Sea II offshore wind project area.
4. Project To Retrofit CTV With Hydrogen Fuel Cells Kicks Off
A project to retrofit a crew transfer vessel (CTV) with hydrogen fuel cells, to cut CO2 and NOx emissions while servicing offshore wind farms, has kicked off.
5.Terna Energy Secures Survey Permit for Wind Farm Sites Offshore Greece
Terna Energy has been granted one out of the two first exploration and survey licences issued for pilot offshore wind projects in Greece.
6. UK Increases Offshore Wind Strike Price Ahead Of Next Auction
The government of the United Kingdom has increased the maximum strike price for offshore wind projects in the next Contracts for Difference (CfD) auction by 66 per cent for fixed-bottom and by 52 per cent for floating wind projects.
All would appear to be positive stories.
- Story 1 is about success in Portugal. What are the Portuguese doing right?
- Stories 2 and 5 are about offshore wind development in new countries; Lithuania and Greece.
- Story 3 may not appear significant, but Terje Aasland, who is Norway’s Minister of Petroleum and Energy seemed pleased in the article.
- Story 4 is about development of new technology, which wouldn’t be done if the market was non-existent.
- Story 6 is surely good news for wind farm developers in the UK.
I did leave out three stories, one of which was negative and two were rather boring. But six out of nine isn’t bad.
Is it Getting Better All The Time, as The Beatles once sang?
Thoughts On The Future Of Orkney
This article on the BBC is entitled Orkney Votes To Explore ‘Alternative Governance‘
This is the sub-heading.
Orkney councillors have voted to investigate alternative methods of governance amid deep frustrations over funding and opportunities.
These paragraphs outline the story.
Council leader James Stockan said the islands had been “held down” and accused the Scottish and UK governments of discrimination.
His motion led to media speculation that Orkney could leave the UK or become a self-governing territory of Norway.
It was supported by 15 votes to six.
It means council officers have been asked to publish a report to Orkney’s chief executive on options of governance.
This includes looking at the “Nordic connections” of the archipelago and crown dependencies such as Jersey and Guernsey.
A further change which would see the revival of a consultative group on constitutional reform for the islands was accepted without the need for a vote.
My Thoughts On The Economic Future Of The Islands
The economic future of Orkney looks good.
Tourism and the traditional industries are on the up, but the islands could play a large part in renewable energy.
The West of Orkney offshore wind farm, which will be a 2 GW wind farm with fixed foundations, is being developed and a large hydrogen production hub at Flotta is being proposed, along with the development of a large quay in Scapa Flow for the assembly of floating wind farms.
The West of Orkney wind farm could be the first of several.
If the future wind farms are further from shore, they will most likely be based on floating technology, with the turbines and their floats assembled in Scapa Flow, from components shipped in from mainland UK and Europe.
Political Future
With a good financial future assured, I believe that Orkney will be able to choose where its political future lies. It could be a Crown Dependency or join Norway.
Whichever way it goes, it could be an island that effectively prints money, by turning electricity into hydrogen and shipping it to countries like Germany, The Netherlands, Poland and Sweden!
From a UK point of view, a Crown Dependency could be a favourable move.
Would Shetland follow the same route?
Offshore Hydrogen Production And Storage
Orkney is not a large archipelago and is just under a thousand square kilometres in area.
It strikes me, that rather than using up scarce land to host the large electrolysers and hydrogen storage, perhaps it would be better, if hydrogen production and storage was performed offshore.
Aker Northern Horizons
In Is This The World’s Most Ambitious Green Energy Solution?, I talk about Northern Horizons, which is an ambitious project for a 10 GW floating wind farm, which would be built a hundred kilometres to the North-East of Shetland, that would be used to produce hydrogen on Shetland.
Other companies will propose similar projects to the West and East of the Northern islands.
This map shows the sea, that could be carpeted with armadas of floating wind farms.
Consider.
- There are thousands of square miles of sea available.
- As the crow flies, the distance between Bergen Airport and Sumburgh Airport in Shetland is 226 miles.
- A hundred mile square is 10,000 square miles or 2590 square kilometres.
- In ScotWind Offshore Wind Leasing Delivers Major Boost To Scotland’s Net Zero Aspirations, I calculated that the floating wind farms of the Scotwind leasing round had an energy density of 3.5 MW per km².
- It would appear that a hundred mile square could generate, as much as nine GW of green electricity.
How many hundred mile squares can be fitted in around the UK’s Northern islands?
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?
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.
Floating Offshore Substation Project Secures EUDP Funding
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Semco Maritime, ISC Consulting Engineers, Aalborg University, Energy Cluster Denmark, and Norway and Sweden-based Inocean have secured funding to further develop a floating offshore substation (FOSS) concept.
This is the first paragraph.
The parties announced their collaboration in 2022 and are now set to further accelerate floating offshore substation development through funding from the Energy Technology and Demonstration Program (EUDP).
These three paragraphs talk about the design.
The substation layout has been developed to fit the shape of a three-column stabilised substructure, according to the partners.
The floating offshore substation is a crucial component in the offshore wind farm industry as deeper ocean sites further from the coastline are to be utilised, the partners said.
Between 60-80 per cent of the world’s offshore wind energy potential is in areas with depths greater than 60+ metres, which presents a need for an alternative solution to bring the power to shore, such as a floating offshore substation, according to the developers.
That all seems sensible.
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.
Stadler To Supply Norwegian Long Distance Trains Making The Journey An ‘Experience In Itself’
The title of this post, is the same as that of this article on the Railway Gazette.
This is the introductory paragraph.
State-owned rolling stock company Norske Tog has selected Stadler as the winner of a contract to supply 17 long distance trainsets to be branded as Flirtnex, with options for 100 more.
The article is very much a must-read or should I say must-look-at?
So Many Floating Wind Designs, So Few Test Sites – Norwegian METCentre Sold Out
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
There are currently more than 80 floating wind technology concepts and designs worldwide, and testing even a certain number of these could prove to be an endeavour since there are not many test sites dedicated to floating wind technology in Europe.
It strikes me that we need more test centres.
As UK waters will in the next couple of decades be home to a lot more GW of wind farms, perhaps we should develop a test centre.
I wonder, if South Wales would be the place for a test centre.
- There is a lot of sea, which isn’t cluttered with oil and gas rigs, and wind farms.
- There are a lot of wind farms planned in the area.
- There are at least two good technology universities.
- There are some deep water ports.
- Electricity connections and power generation are good.
- There is good train connections to the rest of England and Wales.
- A train testing centre is being built at Nant Helen. Some tests needed to be done could be the same.
Some innovative designs for wind turbines are also being developed in South Wales.
Norwegian Companies To Explore Using Aluminium In Floating Offshore Wind Turbines
This is based on this press release from World Wide Wind, which is entitled WORLD WIDE WIND AS and HYDRO ASA Signs Letter Of Intent Aiming At Using Aluminium In Offshore Floating Wind Turbines.
This is the first paragraph.
Hydro, the world leading Norwegian aluminium and energy company and World Wide Wind AS, a Norwegian company developing a floating wind turbine, have signed a Letter of Intent (LoI) to explore the use of aluminium in the renewable wind industry. The two Norwegian companies are partnering up to develop floating wind turbines with a design specifically meant for offshore conditions. The goal is to use sustainable and recyclable materials in the construction, including aluminium.
In Do All Wind Turbines Have To Be Similar?, I said this about the radically different turbines of World Wide Wind.
I’ll let the images on the World Wide Wind web site do the talking.
But who would have thought, that contrarotating wind turbines, set at an angle in the sea would work?
This is so unusual, it might just work very well.
As aluminium is lighter, it might be a factor in the success of the design.
This is the last paragraph of the press release.
World Wide Wind’s integrated floating wind turbines are scalable up to 40MW – 2,5 times current wind turbines – and will use less materials and have a smaller CO2 footprint than conventional turbines. It is World Wide Wind’s ambition that these turbines will represent future design for floating wind turbine design.
40 MW is a very large turbine. This is definitely a case of handsome is as handsome does!
