DEME Returns To Scotland, Announces Offshore Wind Industry Firsts
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
DEME has won the contract to install foundations at the 882 MW Moray West wind farm offshore Scotland.
The industry firsts are described in these paragraphs.
In an industry breakthrough, the Moray West project will be the first time XXL monopiles will be installed in the winter period, and DEME will deploy its double-staged, motion-compensated pile gripper, the company said.
Moray West will also be the first time a vibro-hammer is being utilised for the XXL monopiles to overcome weaker soil layers.
Note.
- The water depth at Moray West wind farm is 35-54 metres, which necessitates the XXL monopiles.
- Working offshore in winter can be challenging.
- DEME’s gripper sounds just like what the engineers wanted.
This is just like with North sea oil and gas, where everything got bigger and more capable over time. But it did speed construction!
Global Port Services Wins Pre-Assembly Contract For Scottish Offshore Wind Farm
The title of this post, is the same as that of this article on offshoreWIND.biz.
These are the first two paragraphs.
Global Port Services, owned by Global Energy Group alongside the Port of Nigg, has secured multiple contracts to support Seagreen Wind Energy Limited (SWEL) with site-enabling works for the pre-assembly construction of wind turbine components at its Port of Nigg facility.
The news comes as the final turbine foundations for the Seagreen offshore wind project arrive at Nigg to be prepared for installation 27 kilometres off the coast of Angus.
Note.
- Nigg is a village in the Highlands to the North of Inverness.
- The Port of Nigg has a busy Marine Fabrication Yard.
- There is a very interesting BBC documentary called Rigs of Nigg, which tells some of the stories of the port from the 1970s.
- As the article indicates, the yard is now very much involved in the wind power industry.
- SSE have invested in the yard.
This Google Map shows the port.
Note. all the yellow steel structures, which look like the fixed foundations for the Seagreen Wind Farm.
I am a bit surprised that foundations for Seagreen are being assembled a fair distance from Angus.
Is there not a fabrication yard on the Firth of Forth?
Scotland’s Largest Offshore Wind Farm Entering Home Stretch

100 MW Scottish Floating Wind Project To Deliver Lifetime Expenditure Of GBP 419 Million
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub heading, that gives more details on lifetime expenditure and full-time equivalent (FTE) jobs created.
The 100 MW Pentland Floating Offshore Wind Farm in Scotland is estimated to deliver lifetime expenditure of GBP 419 million in the UK and to support the creation of up to 1,385 full-time equivalent (FTE) jobs.
It does seem these figures have been compiled using the rules that will apply to all ScotWind leases and have used methods laid down by Crown Estate Scotland. So they should be representative!
Does it mean that a 1 GW floating wind farm would have a lifetime expenditure of £4.19 billion and create 13, 850 full-time equivalent (FTE) jobs?
This article from Reuters is entitled UK Grid Reforms Critical To Hitting Offshore Wind Targets and contains this paragraph.
The government aims to increase offshore wind capacity from 11 GW in 2021 to 50 GW by 2030, requiring huge investment in onshore and offshore infrastructure in England, Wales and Scotland.
If I assume that of the extra 39 GW, half has fixed foundations and half will float, that means that there will be 19.5 GW of new floating wind.
Will that mean £81.7 billion of lifetime expenditure and 270,075 full-time equivalent (FTE) jobs?
Conclusion
It does seem to me, that building floating offshore wind farms is a good way to bring in investment and create full time jobs.
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.
BP To Open Offshore Wind Office In Germany, Starts Recruitment Drive
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the first paragraph, which adds a bit more information.
Global energy major bp plans to open an office in Hamburg, Germany dedicated to the development of offshore wind projects and is in the process of seeking employees for the new office.
These are other points from the article.
- The topic of wind power is being promoted particularly in Hamburg.
- BP said that the company has already achieved a number of milestones in the field of wind energy.
- In cooperation with EnBW, bp is currently developing several wind farms in the Irish and Scottish Seas.
- Similar plans already exist for the Netherlands.
- The energy major would also like to supply charging stations for electric vehicles with green electricity.
- In Germany, wind and solar energy should account for 80 per cent of electricity generation by 2030, compared to today’s 42 per cent.
- Offshore wind energy is planned to grow seven times by 2045.
I believe that BP’s project expertise and management, backed by billions of German euros could be a complimentary dream team.
Offshore And Nearshore Survey Work Complete For 2 GW Scottish Wind Project
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the first paragraph.
The developers of the West of Orkney Windfarm have completed its 2022 offshore and nearshore surveys for the project area, located around 25 kilometres off the Sutherland coast in Scotland.
Note.
- Surveys were on time and on budget.
- Consent applications are expected next year.
- Both fixed and floating turbines are being considered.
The West of Orkney wind farm has its own web site, with this proud mission statement.
Designed For Delivery, Driven By Scale
The West of Orkney Windfarm has the potential to power more than two million homes and deliver long-term economic benefits to communities across the north of Scotland.
The web site says that the target for first power generation is 2029.
In How Long Does It Take To Build An Offshore Wind Farm?, I said that it typically takes between six and eight years to for consent to commissioning for an offshore wind farm.
So with consent in 2023, commissioning in 2029 could be possible.
Knoydart Renewables – The Power of Knoydart
The BBC has been showing a film all day about the Knoydart area of the Scottish Highlands and their community-owned hydroelectric power system.
The title of this post, is the same as that of this page on the Knoydart Foundation web site.
This paragraph introduces the system.
Knoydart is not connected to the National Grid and generates all of its own electricity. Other than some small run-of-burn micro-schemes in outlying hamlets, by far and away the the main producer and distributer of electricity on Knoydart is Knoydart Renewables Ltd. that supplies electricity around Inverie Bay.
Note.
- The system is based on a 280 kW turbine and generator.
- The turbine is fed over a kilometer by steel and plastic pipe from a man-made loch with an estimated storage capacity of at least 74 MWh.
- There is a back-up diesel generator.
- 120 residents in 90 properties are supplied with electricity.
It sounds like a very professional system for a community with a convenient hill and water supply.
The system is being expanded and connected to the grid.
The whole page is a must read for anyone, who wants to put in a small hydroelectric power station for their house, castle or community.
‘Ryanair Of Rail’ Lights Up The East Coast On Fast Track To Profit
The title of this post, is the same as that of this article on The Times.
This is the first paragraph.
A cut-price rail service between London and Edinburgh, dubbed the Ryanair of rail, is on track to turn a profit after a year in service and has helped to reverse the airlines’ previous dominance of the travel market between the capitals.
Other points from the article.
- Lumo will carry its millionth passenger in November.
- The average one-way fare has been less than £40.
- Rail is now claiming 63 % of the London and Scotland travel market.
Will this success lead to more trains attracting more rail travellers between England and Scotland?
Can Lumo Carry More Passengers?
Lumo use five-car Hitachi Class 803 trains for their services.
- Their fleet consists of five cars.
- Each five-car train can carry 402 passengers.
- Lumo run five trains per day (tpd) in both directions.
There are various ways that the number of passengers could be increased.
Could Lumo Run More Services?
This may seem to be a solution, but only a fixed number of trains can be run in every hour, between England and Scotland.
- Other train operators may also want to run more services.
- It would also mean Lumo would need to buy more trains.
On the other hand it may be possible to squeeze in perhaps one extra service.
Could Lumo Run Longer Trains?
Lumo’s Class 803 trains are unusual among the Hitachi AT 300 trains, that handle long distance services all over the UK, in that they have no diesel engines and rely on battery power for emergencies.
As the trains’ computer work out which cars are present, I wouldn’t be surprised that these trains can be lengthened or even run as a pair, as GWR’s and LNER’s five-car Hitachi trains often do.
Platforms at King’s Cross, Stevenage, Newcastle, Morpeth and Edinburgh are probably already longer than is needed for a five-car train.
I could even see Lumo adding coaches as required to satisfy the need of the day. On a day like the Calcutta Cup, they might even run ten or twelve car trains, which is the longest formation possible with the Hitachi trains. But they’d have to have enough coaches!
Lumo use a very simple catering option, which I suspect can be modified to serve a longer train.
I am fairly certain, that LUMO’s fleet has been designed for gradual lengthening to expand capacity.
Would The Lumo Model Work On The West Coast Main Line?
As the Lumo model seems to work to Edinburgh, would it work to Glasgow?
I don’t see why not! And it might improve the service from Avanti West Coast?
Grand Union have lodged an application to run four tpd between London and Stirling via at Milton Keynes Central, Nuneaton, Crewe, Preston, Carlisle, Lockerbie, Motherwell, Whifflet, Greenfaulds and Larbert with InterCity 225s.
This proposal seems to be stalled at the moment, but I do feel it is a good idea.
I would certainly use it, as the air-conditioning on the Class 390 trains, used by Avanti West Coast, makes me ill!
CIP Picks Stiesdal Floater For 100MW Scottish Offshore Wind Farm
The title of this post, is the same as that of this article on Offshore Engineering.
These two paragraphs introduce the project.
Copenhagen Infrastructure Partners (CIP) has selected Stiesdal Offshore’s TetraSub floating foundation structure for the 100MW Pentland Floating Offshore Wind Farm project, to be located off the coast of Dounreay, Caithness, Scotland.
The technology has been said to offer a lightweight and cost-effective floating solution, based on factory-made modules which are then assembled domestically in port to form a complete foundation.
Note.
- The TetraSub seems to have been designed for ease of manufacture.
- One if the aims appears to be to build a strong local supply chain.
- The TetraSub was designed with the help of Edinburgh University.
- The TetraSpar Demonstrator is in operation off the coast of Norway.
- This page on Mission Innovation describes the TetraSpar in detail.
- The TetraSpar foundation, owned by Shell, TEPCO RP, RWE, and Stiesdal.
- It can be deployed in water with a depth of up to 200 metres.
- Currently, they carry a 3.6 MW turbine.
- At that size, they’d need 27 or 28 turbines to create a 100 MW wind farm.
The home page of the Pentland Offshore Wind Farm gives more details.
This article on offshoreWIND.biz is entitled CIP And Hexicon To Halve Pentland Floating Wind Project Area.
- The project area has been halved.
- The number of turbines has been reduced from ten to seven.
- Compact turbines will be used.
- The project will be built in two phases, one turbine in 2025 and six in 2026.
- Effectively, the first turbine will help to fund the second phase, which eases cash flow.
The changes show how the wind farm has changed during development due to local pressures and improved technology.
Conclusion
It does seem that the competition is growing in the field of floating wind turbines.
Given the quality of the research and backing for these floats and the fact they now have an order, I wouldn’t be surprised to see this technology be a success.
