SeaTwirl And Verlume Join Forces To Drive Decarbonisation Of Offshore Assets
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Swedish energy-tech company SeaTwirl and UK-based energy management and energy storage firm Verlume have signed a memorandum of understanding (MoU) to collaborate on the electrification of offshore assets and decarbonisation of the oil and gas industry.
This is the first two paragraphs.
The MoU will see the two companies identify and pursue potential opportunities for decarbonisation of offshore oil and gas and other associated offshore electrification opportunities using renewable energy, seabed-based energy storage, and intelligent energy management.
SeaTwirl and Verlume plan to develop systems for commercial sale, using combined technologies.

This could be an MoU made in engineering heaven.
Verlume And Wave Power
The last two paragraphs of the article describe another project involving Verlume.
Aberdeen’s intelligent energy management specialists Verlume has developed a GBP 2 million (approximately USD 2.5 million) project linking the Blue X wave energy converter constructed by Mocean Energy with a Halo underwater battery storage system.
The industry-supported project, situated five kilometres east of Orkney Mainland, demonstrates the integration of green technologies to deliver consistent and sustainable low-carbon power and communication to subsea equipment.
Could Verlume, be the missing link that wave power needs?
Energy / Sullom Voe Terminal To Be Connected To The Grid By The End Of Next Year
The title of this post, is the same as that of this article on Shetland News.
This is the sub-heading.
POWER supply to the Sullom Voe Terminal is set to be provided by two 43-kilometre underground power lines from the Gremista substation by the end of next year.
These four paragraphs outline some of EnQuest’s plans.
The on-site gas-fired power station, operated by Equans, is due to be switched off in the fourth quarter of 2025 as it no longer meets stringent carbon emission standards.
EnQuest, the operator of the terminal, gave an update on its plans for the 1,000-acre site during a Shetland suppliers forum held at Mareel on Wednesday morning.
The company was keen to present itself as one that is seeking collaborative working with the local businesses and the community as Sullom Voe transitions from an oil terminal to a green energy hub.
The company is in the middle of a “right-sizing” project that involves some significant decommissioning of equipment no longer needed to make space for long-term aspiration such as carbon capture and storage, green hydrogen production and offshore electrification.
Note.
- Two underground cables will be coming from Gremista to Sullom Voe.
- Up to seven wind turbines could fit on the site to produce power needed for green hydrogen production.
- Shetland is set to be connected to the UK national grid later this year thanks to a new 600MW HVDC subsea transmission link which will run to Caithness.
- The Sullom Voe power station, once switched off, could be “repurposed” to continue producing energy using clean fuels.
- EnQuest are certainly doing a comprehensive job on the transition.
- It looks to be a well-thought out plan to convert existing oil and gas infrastructure to a modern green asset.
This Google map shows Gremista to Sullom Voe.
Note.
- Sullum Voe is at the top of the map.
- Gremista is marked by the red arrow.
- It looks like the cable could take mainly a straight North-South route.
This second Google map shows Sullum Voe
Note.
- The Sullum Voe terminal is at the top of the map.
- Sullum Voe is a 1,000-acre site.
- In the South-West corner is the closed Scatsta airport.
This third Google map shows Lerwick.
Gremista is marked by the red arrow.
I do have some thoughts.
Scatsta Airport
Consider.
- It takes takes over three hours on a bus between Lerwick and Sullum Voe
- Scatsta Airport only closed in 2020.
Is there an opportunity for an air taxi between Lerwick and Scatsta?
The Invisible £20 Billion North Sea Project
I introduced Cerulean Winds in the two posts What Is INTOG? and Cerulean Winds Is A Different Type Of Wind Energy Company.
They have now expanded their page on the North Sea Renewables Grid.
It is well worth a look!
Flotation Energy, Vårgrønn Seal Exclusivity Agreements For 1.9 GW Scottish Floaters
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Vårgrønn, a joint venture between Plenitude (Eni) and HitecVision, and Flotation Energy have signed exclusivity agreements for two floating offshore wind developments under Crown Estate Scotland’s Innovation and Targeted Oil and Gas (INTOG) leasing round.
These two paragraphs give more details.
Once completed, the floating offshore wind farms, with up to a total of 1.9 GW capacity, will provide renewable electricity to oil and gas platforms, aiming to reduce carbon emissions from the assets they supply.
In addition, Green Volt and Cenos projects will also provide electricity to the UK grid.
Note.
I can’t see a loser with these wind farms.
- The wind farms provide zero-carbon electricity to oil and gas platforms.
- These platforms cut their emissions, by not using fossil fuels to generate the electricity they need for their operation.
- Some platforms use gas to generate the electricity, so this gas can be delivered to the shore for the UK gas network.
- Any spare electricity will be available for using in the UK electricity grid.
- Crown Estate Scotland will be paid for the lease for the wind farm.
There will be no carbon emissions from the platforms, but there will be extra onshore emissions from any gas that is currently used to power the platforms, if it is burnt onshore in power stations and industrial processes, or used for heating.
But increasingly gas in the UK will be used in applications, where the carbon emissions can be captured for use or storage.
It will be very interesting to see how as offshore operations are decarbonised our total carbon emissions change.
Biggest Untapped UK Oil Field, Rosebank, Approved By Regulators
The title of this post, is the same as that of this article on the BBC.
This is the BBC’s summary so far.
- The UK’s largest untapped oil field has been approved by regulators
- Rosebank, 80 miles west of Shetland, is estimated to contain 500 million barrels of oil
- The UK government welcomes the decision, saying it will raise billions of pounds and “make us more secure against tyrants like Putin”
- But Scotland’s First Minister Humza Yousaf says he’s “disappointed”, while the Green Party calls the decision “morally obscene”
- Regulators said net zero considerations had been taken into account
This is my summary.
I have been reading Equinor’s web site on Rosebank.
Production will use what is known as a Floating Production Storage and Offloading Vessel or FPSO, which means, when they’ve finished, it can just sail away.
The FPSO will also be electrification-ready, so that all operations on the vessel will probably be powered by green electricity from a nearby wind farm, instead of by a gas turbine engine on the vessel, which burns gas.
This means that the offshore operations will be as carbon-free as is reasonably possible. But importantly, we will pipe the maximum amount of gas from the field for either our own use or selling to the gas-thirsty Germans.
We will need the gas for some time to back up wind and solar with gas-fired power stations.
But what about the emissions from the power stations?
Capturing carbon dioxide from a power station is getting easier, but more importantly, researchers are finding more and more innovative ways of using the carbon dioxide.
H & M and Zara are even selling clothes made from captured carbon dioxide.
Ways are also being developed using plasma electrolysis to strip the carbon out of natural gas to leave useful hydrogen.
Natural gas will be our friend for many decades yet, if we can turn it into a zero-carbon fuel, which I believe we can!
World’s Largest Floating Offshore Wind Farm Officially Opens
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Norwegian energy major Equinor, together with its partners, will inaugurate today the world’s largest floating offshore wind farm, Hywind Tampen
The story is according to Reuters.
This page on the Equinor web site, outlines the project.
Hywind Tampen is the world’s first floating wind farm built specifically to power offshore oil and gas installations, and is now supplying electricity to Equinor’s oil and gas fields Snorre and Gullfaks in the Norwegian North Sea.
With a system capacity of 88 MW it is also the world’s largest floating offshore wind farm and an important step forward in industrialising solutions and reducing costs for future offshore wind power projects.
With Hywind Tampen now operational, Equinor is now operating nearly half (47 percent) of the world’s offshore floating wind capacity.
This floating wind farm powering oil and gas fields will be the first of many.
SeaTwirl, Kontiki Winds To Explore Powering Oil & Gas Assets With Floating Wind
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The Sweden-headquartered SeaTwirl has signed a Memorandum of Understanding (MoU) with Kontiki Winds to identify and discuss the opportunities to electrify oil and gas assets and other offshore applications, with the use of SeaTwirl’s floating wind turbines.
And this is the first paragraph.
Under the MoU, the two companies will explore new opportunities in the market to implement offshore wind into new and existing oil and gas assets and microgrid applications such as the powering of fish farms, desalination plants and/or other small-scale applications that currently are based on fossil fuel electricity generation.
Note.
- The current turbines are only 1 MW.
- They appear to be mounted on a long monopole foundation.
- My mathematical modelling experience suggests to me, that these could be very stable devices.
- I suspect they could be built into specialist equipment like a buoy with a light to mark something.
I suspect that there will be large numbers of applications, especially if the manufacture and installation of Sea Twirl’s turbines is an efficient process.
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?
N-Sea To Connect German Offshore Wind Farm To Dutch Gas Platform
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Dutch upstream oil and gas company, ONE-Dyas, has awarded N-Sea with a contract to install a subsea power cable between the Riffgat offshore wind farm in the German North Sea and the new, to-be-built N05-A gas production platform.
At a first look it appears that wind power is being used to power the gas production platform.
Other points from the article include.
- The distance of the connecting cable is ten kilometres.
- The Dutch government approved the scheme in June 2022.
- A final investment decision was made in September 2022.
I have some thoughts and further information.
Borkum, Rottumerplaat and Schiermonnikoog
The article says this about the position of the gas platform.
The N05-A platform will be installed some 20 kilometres north of the islands of Borkum, Rottumerplaat and Schiermonnikoog, and approximately one and a half kilometres from German waters.
This Google Map shows the three islands.
Note.
- Borkum is the horseshoe-shaped German island in the North-East corner of the map.
- Schiermonnikoog is the long and thin island in the West.
- Rottumerplaat is the larger of the two Dutch islands in middle map.
- Eemhaven, which I wrote about in The Train Station At The Northern End Of The Netherlands, is in the South-East corner of the map.
Shipping routes run up the River Ems and German-Dutch border in the East of the map
Riffgat Wind Farm
This web page on the EWE web site, gives this description of the wind farm.
EWE has built the first commercial wind farm in the German North Sea in summer 2013 with Riffgat. The modern wind farm has a total capacity of 108 megawatts of power and can supply around 120,000 households with environmentally friendly electricity. In just 14 months of construction, the 30 wind turbines of the 3.6 megawatt class have been installed 15 kilometers off the north seas of Borkum. The rotor diameter of the units is 120 meters, while the hub height is 90 meters, which corresponds to the height of the Bremen dome. Overall, the plants are 150 meters high from the water surface to the top rotor blade tip. They are founded on 70 meter long steel foundations (monopiles), 40 meters deep in the sea bottom. The water depth in the wind farm is between 18 and 23 meters. In addition to the wind power plants, Riffgat also consists of a substation which transports the generated electricity to a better transportable voltage level.
It looks a pretty standard 100 MW wind farm with fixed foundations.
The N05-A Platform
The article says this about the N05-A project.
The N05-A project is part of the so-called GEMS area, an area approximately 20 to 80 kilometres north of the Ems estuary. ONE-Dyas, together with partners Hansa Hydrocarbons and EBN, aims to extract natural gas from the N05-A field as well as surrounding fields in the German and Dutch North Sea.
The GEMS area has a web site with a URL with a .co.uk extension.
It has an informative video, which I don’t think would go down with Dutch chapter of Just Stop Oil.
The North Sea’s First Gas Platform To Run Entirely On Wind Power
The article says this about the N05-A project.
While the N05-A platform will not be the first in the North Sea to run on wind energy, it will be the first to do so entirely.
Hywind Tampen floating wind farm will be the first.
Conclusion
This looks like a good pragmatic solution to me.
I can see more connections between offshore wind farms and oil and gas facilities all over the world.
