MPS Floating Platform To Feature FibreMax Tendons

The title of this post, is the same as that of this article on

This is the sub-heading.

Welsh company Marine Power Systems (MPS) has joined forces with FibreMax to provide integrated floating foundation and tendon solutions to the growing floating offshore wind sector.

And these three paragraphs outline the design.

The tendon solution will be used in the anchoring and moorings of MPS’ tension leg platform (TLP), called PelaFlex, to deliver the highest system stability and zero tilt, the partners said.

It will be the “world’s first” TLP with FibreMax tendons, made with Twaron fiber from Japan-headquartered Teijin.

Compared to traditional steel moorings synthetic cable offers a much better strength-to-weight ratio, longer operational life, and lower levels of maintenance, according to the partners.


  1. PelaFlex tension leg platforms are used in the project I wrote about in Simply Blue Group And Marine Power Systems To Pursue INTOG Innovation Project Opportunity.
  2. Wikipedia is a good source of information on tension leg platforms, where there is a large section on how they could be used for wind turbines.
  3. Twaron has an informative product page.
  4. There is more about PelaFlex on the PelaFlex web page including a video.
  5. The press release for the joint Simply Blue/MPS project talks of six turbines totalling up to 100 MW, which is probably around 17 MW per wind turbine.

It looks to me, that the PelaFlex design is getting better by the simple process of adding lightness and therefore being able to have a higher energy density in a deep area of the sea.

The amount of innovation involved probably makes PelaFlex an ideal component for the upcoming INTOG leasing round.

ERM To Lead EIA For Salamander Floating Project Offshore Scotland

The title of this post, is the same as that of this article on

This is the sub-heading.

A joint venture (JV) between Simply Blue Group, Ørsted, and Subsea7 has selected ERM Group company MarineSpace to lead the environmental impact assessment (EIA) for its Salamander floating offshore wind project in Scotland.


  1. The Salamander floating offshore wind farm is going to be a 100 MW wind farm 35 km. North of Peterhead.
  2. It is likely to be a pathfinder, in the development of new facilities to build wind farm structures and components in the North of Scotland.
  3. I talked about the floaters in Ocergy Floaters Selected For 100 MW Project Off Scotland.
  4. I suspect that it could be an INTOG project.

Salamander seems to be progressing at a decent pace.

Offshore Wind Developers Answer Scotland’s Call For Innovation, Oil And Gas Decarbonisation

The title of this post, is the same as that of this article on

This is the sub-heading.

Crown Estate Scotland has received a total of 19 applications for its Innovation and Targeted Oil and Gas (INTOG) offshore wind leasing process.


Note that there are two sections to INTOG.

This document on the Crown Estate Scotland web site, is entitled INTOG – Public Summary and it defines the two sections.


  • To enable projects which support cost reduction in support of commercial deployment of offshore wind including alternative outputs such as Hydrogen.
  • To further develop Scotland as a destination for innovation and technical development which will lead to risk reductions and supply chain opportunity.

Applications in this section should be no more than 100 MW in capacity.

Targeted Oil and Gas:

  • To maximise the role of offshore wind to reduce emissions from oil and gas production.
  • To achieve target installed capacity in a way that delivers best value for Scotland, creating supply chain opportunity in alignment with Just Transition principles.

A rough estimate is that powering rigs by using offshore wind would increase gas production by around ten percent.

The Applications

The article says this about the applications.

Of the 19 applications, ten are for the Innovation part, while nine have been submitted for the TOG element.

It is expected that up to 500 MW will be awarded to innovation projects and around 4 GW for projects looking to decarbonise oil and gas assets.

The article also lists the known bidders.


I believe that there is going to be some outstanding applications for leases under the INTOG scheme.

I have already written about Cerulean Winds ambitious proposal in Cerulean Winds Is A Different Type Of Wind Energy Company, which could result in 6 GW of wind turbines installed amongst the oil and gas fields to provide electricity and decarbonise the platforms and rigs.

Increased CCS Can Decarbonise GB Electricity Faster On Route To Net Zero

The title of this post, is the same as that of this news item on the SSE web site.

This is the first paragraph.

Building more power carbon capture and storage plants (Power CCS) could significantly accelerate the UK’s plans to decarbonise the GB electricity system on route to net zero, according to new analysis commissioned by SSE.

I am not surprised, as in my time, I have built several production, storage and distribution mathematical models for products and sometimes bringing things forward has beneficial effects.

These three paragraphs summarise the findings.

The UK Government’s proposed emissions reductions from electricity for 2035 could be accelerated to 2030 by combining its 50GW offshore wind ambition with a significant step up in deployment of Power CCS. This would require 7-9GW (equivalent to 10-12 plants) of Power CCS compared to the current commitment of at least one Power CCS plant mid-decade, according to experts at LCP Delta.

Replacing unabated gas with abated Power CCS generation will deliver significant reductions in greenhouse gas emissions. The analysis suggests that adding 7-9GW Power CCS to the UK’s 2030 offshore wind ambition will save an additional 18 million tonnes of CO2 by 2040, by preventing carbon emissions during periods when the sun isn’t shining, and the wind isn’t blowing.

Gas consumption for electricity generation would not significantly increase, given the 7-9GW Power CCS would displace older and less efficient unabated gas power stations already operating and reduce importing unabated gas generation from abroad via the interconnectors. Importantly, Power CCS can provide a safety net to capture emissions from any gas required to keep the lights on in the event of delays to the roll out of renewables or nuclear.

The report is by LCP Delta, who are consultants based in Edinburgh.

The report says this about the transition to hydrogen.

Power CCS also presents significant opportunities to kickstart, then transition to, a hydrogen economy, benefitting from the synergies between CCS and hydrogen, including proximity to large-scale renewable generation and gas storage facilities which can support the production of both electrolytic and CCS-enabled hydrogen.

And this about the reduction in carbon emissions.

The existing renewables ambition and the accelerated Power CCS ambition are expected to save a total of 72 million tonnes of CO2 by 2040 compared to commitments in the UK’s Net Zero Strategy from October 2021.

I don’t think there’s much wrong with this analysis.

But of course the greens will trash it, as it was paid for by SSE.

I have a few thoughts.

Carbon Capture And Use

I believe we will see a great increase in carbon capture and use.

  • Carbon dioxide is already an ingredient to make Quorn.
  • Carbon dioxide is needed for fizzy drinks.
  • Carbon dioxide can be fed to tomatoes, salad plants, herbs and flowers in giant greenhouses.
  • Carbon dioxide can be used to make animal and pet food.
  • Carbon dioxide can be used to make building products like plasterboard and blocks.
  • Carbon dioxide can be added to concrete.
  • Carbon dioxide can be used as a refrigerant and in air-conditioning. There are one or two old Victorian systems still working.

Other uses will be developed.

Carbon Capture Will Get More Efficient

Carbon capture from power stations and boilers, that use natural gas is a relatively new process and its capture will surely get better and more efficient in the next few years.

Gas From INTOG

I explain INTOG in What Is INTOG?.

One of INTOG’s aims, is to supply electricity to the oil and gas rigs and platforms in the sea around the UK.

Currently, these rigs and platforms, use some of the gas they produce, in gas turbines to create the electricity they need.

  • I have seen reports that ten percent of the gas that comes out of the ground is used in this way.
  • Using the gas as fuel creates more carbon dioxide.

Decarbonisation of our oil and gas rigs and platforms, will obviously be a good thing because of a reduction of the carbon dioxide emitted. but it will also mean that the gas that would have been used to power the platform can be brought ashore to power industry and domestic heating, or be exported to countries who need it.

Gas may not be carbon-neutral, but some gas is more carbon-neutral than others.

SSE’s Plans For New Thermal Power Stations

I have taken this from SSE’s news item.

SSE has deliberately chosen to remain invested in the transition of flexible thermal electricity generation due to the key role it plays in a renewables-led, net zero, electricity system and is committed to decarbonising the generation.

Together with Equinor, SSE Thermal is developing two power stations equipped with carbon capture technology. Keadby 3 Carbon Capture Power Station is based in the Humber, the UK’s most carbon-intensive industrial region, while Peterhead Carbon Capture Power Station is located in the North East of Scotland. Combined, the two stations could capture around three million tonnes of CO2 a year.

Studies have shown that Keadby and Peterhead Carbon Capture Power Stations could make a lifetime contribution of £1.2bn each to the UK economy, creating significant economic opportunity in their respective regions. Both will be vital in supporting the huge amount of renewables which will be coming on the system.

SSE Thermal and Equinor are also collaborating on Keadby Hydrogen Power Station, which could be one of the world’s first 100% hydrogen-fuelled power stations, and Aldbrough Hydrogen Storage, which could be one of the world’s largest hydrogen storage facilities.


  1. SSE appear to think that gas-fired power stations with carbon capture are an ideal backup to renewables.
  2. If gas is available and it can be used to generate electricity without emitting any carbon dioxide, then why not?
  3. Hydrogen is coming.

Things will get better.

Is A Virtuous Circle Developing?


  • Spare wind electricity is turned into hydrogen using an electrolyser or perhaps some world-changing electro-chemical process.
  • The hydrogen is stored in Aldbrough Hydrogen Storage.
  • When the wind isn’t blowing, hydrogen is used to backup the wind in Keadby Hydrogen power station.
  • The other Keadby power stations can also kick in using natural gas. The carbon dioxide that they produce, would be captured for storage or use.
  • Other users, who need to decarbonise, can be supplied with hydrogen from Aldbrough.


  1. Gas turbines are throttleable, so if National Grid wants 600 MW to balance the grid, they can supply it.
  2. As time progresses, some of the gas-fired power stations at Keadby could be converted to hydrogen.
  3. Rough gas storage is not far away and could either store natural gas or hydrogen.
  4. Hydrogen might be imported by tanker from places like Africa and Australia, depending on price.

Humberside will be levelling up and leading the decarbonisation of the UK.

If you have an energy-hungry business, you should seriously look at moving to Humberside.

An Analysis Of UK Offshore Wind Farms

This analysis is based on this Wikipedia entry which is entitled A List Of Offshore Wind Farms In The United Kingdom.

The page has these sections.

Operational Offshore Wind Farms

October 2022 – 13628 MW

Wind Farms Under Construction

October 2022 – 4160 MW

Pre-Construction Wind Farms

October 2022 – 2453 MW

Proposed Wind Farms – Contracts for Difference Round 3

October 2022 – 12 MW

Proposed Wind Farms – Contracts for Difference Round 4

October 2022 – 7614 MW

Proposed Wind Farms – Early Planning (England)

October 2022 – 15723 MW

Proposed Wind Farms – Early Planning (Wales)

October 2022 – 500 MW

Proposed Wind Farms – Early Planning (Scotland)

October 2022 – 30326 MW

Total of Operational, Under Construction And Proposed Wind Farms

October 2022 – 60788 MW

Possible Wind Farms

In addition, these wind farms have been talked about and could possibly be developed.

  • Celtic Sea – Erebus – 100 MW Demonstration Project
  • Celtic Sea – Valorus – 300 MW Early-Commercial Project
  • Celtic Sea – Petroc – 300 MW Project
  • Celtic Sea – Llywelyn – 300 MW Project
  • Celtic Sea – Llŷr Wind – 100 MW Project
  • Celtic Sea – Llŷr Wind – 100 MW Project
  • Celtic Sea – Gwynt Glas – 1000 MW Project
  • Scotland – Salamander – 100 MW Project
  • Scotland – West of Orkney – 2000 MW Project
  • East Of Shetland – Map Reference 18 – 500 MW Project
  • East Of Shetland – Map Reference 19 – 1800 MW Project
  • East Of Shetland – Map Reference 20 – 500 MW Project
  • Shetland – Northern Horizon – 10000 MW Project
  • INTOG – Cerulean Winds – 6000 MW Project

These figures total 8700 MW, so by the early 2030s, it would not be unreasonable to see an offshore wind capacity of nearly 9000 MW or 90 GW.

Hywind Tampen

In Equinor Sets Sights On Gigawatt-Scale Floating Offshore Wind Projects In Celtic Sea, I said this about Hywind Tampen.

Equinor is also currently constructing the 88 MW Hywind Tampen project in Norway, which will be the largest floating offshore wind farm in the world when completed in 2023.

This page on the Equinor web site gives more details of Hywind Tampen.

  • Hywind Tampen is a floating wind farm under construction that will provide electricity for the Snorre and Gullfaks oil and gas fields in the Norwegian North Sea.
  • It will be the world’s first renewable power for offshore oil and gas.
  • With a system capacity of 88 MW it will also be the world’s largest floating offshore wind farm.
  • The wind farm will consist of eleven 8 MW turbines.

When Hywind Tampen is operational, Equinor will operate nearly half (47 percent) of the world’s floating wind capacity.

This paragraph from the Equinor web page is significant.

The wind farm is estimated to meet about 35% of the annual electricity power demand of the five Snorre A and B, and Gullfaks A, B and C platforms. In periods of higher wind speed this percentage will be significantly higher.

I take this to mean that the gas turbines that currently supply the five platforms will be left in place and that their output will be replaced by wind power, when it is available.

The INTOG Program

I described this in What Is INTOG?, and it is the UK’s program, that includes electrification of rigs and platforms.

The first leases under INTOG would appear to be expected in March 2023.

Decarbonisation Of Offshore Operations Around The World

I’m sure that if Hywind Tampen and/or INTOG is successful, that the technology will be used where possible around the world.

Ocergy Floaters Selected For 100 MW Project Off Scotland

The title of this post, is the same as that of this article on

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.


  1. There is a picture showing two turbines on OCG-Wind floats.
  2. Salamander is intended to be an INTOG project of 100 MW.
  3. The floaters are expected to be fabricated at Global Energy Group’s Port of Nigg.
  4. 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.

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


  • 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.


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.

Simply Blue Group And Marine Power Systems To Pursue INTOG Innovation Project Opportunity

The title of this post, is the same as this of this press release from Simply Blue Group.

These two paragraphs explain the proposals.

Marine Power Systems (MPS) have partnered with Simply Blue Group to develop a project proposal for the Innovation and Targeted Oil and Gas (INTOG) leasing round run by Crown Estate Scotland.

The collaboration between Simply Blue Group and MPS would see six wind turbines deployed on the MPS floating platform, PelaFlex, in waters between 60 and 100m in depth, delivering a total capacity of 100MW.

The INTOG proposal, that I outlined in What Is INTOG?, seems to have got engineers and financiers thinking.

Simply Blue Group are quoted saying this about the PelaFlex platform.

MPS has been selected as the preferred technology partner based on the strengths of their structurally efficient tension legged platform which delivers significantly reduced system mass and a smaller mooring footprint than its peers. The technology has been designed to optimise local content delivery through a decentralised logistics model, and those benefits help utility scale developers minimise costs whilst maximising local economic benefits and accelerating industrial scale farm development.

That sounds good to me!

There is also more on the PelaFlex web page including a video.

The Turbine Size

The press release talks of six turbines totalling up to 100 MW, which is probably around 17 MW per wind turbine.

These are no ordinary wind turbines!


The press release also says this about INTOG.

The INTOG leasing round aims to support projects that will directly reduce emissions from oil and gas production (up to a total capacity of 5.7GW) but also drive commercialisation and innovation in offshore wind (up to a total capacity of 500MW) as well as support supply chain development. This forms part of the Scottish Government’s drive to reach net zero emissions by 2045 where the decarbonisation of oil and gas installations is seen as playing an important role in the transition to net zero.

Decarbonisation of our oil and gas fields, will obviously be a good thing because of a reduction of the carbon dioxide emitted. but it will also mean that the gas that would have been used to power the platform can be brought ashore to power industry and domestic heating, or be exported to countries who need it.


INTOG seems to be a good idea, as it is provoking new and innovative designs.

Harbour Energy

This article in The Times in the Tempus column is entitled Oil And Gas Producer Harbour Energy Offers Safe Haven.

This is the first paragraph.

Booming commodity prices mean Harbour Energy is throwing off cash and yet the biggest oil and gas producer in the UK North Sea is still struggling to gain credibility in the eyes of investors.

Reading the column, it does seem a bit of a paradox, when the author says.

  • London-listed oil and gas companies are cheap.
  • Harbour Energy is in the bargain basement.
  • The share price doesn’t reflect the P/E ratio.
  • The company seems to have the money for acquisitions.
  • It doesn’t seem to have taken advantage of the Ukraine situation.
  • Revenues should transform its cash flow position.

The author finishes by recommending to buy the shares.

In Cerulean Winds Is A Different Type Of Wind Energy Company, I introduced Cerulean Winds and their £30 billion plan to decarbonise much of North Sea oil and gas production. This sensational plan is described in full on this page of their web site, which is entitled The Cerulean Winds Intog Scheme.

It strikes me that Harbour Energy could be the sort of energy company that could benefit from Cerulean Winds’s scheme.

  • It could increase their gas production by ten percent.
  • Harbour Energy probably have the money to decarbonise.
  • Would decarbonising their North Sea operations improve the company’s profile?

I will certainly watch for any links between the two companies.
