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 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.

Belgians To Start Building World’s First Artificial Energy Island Next Year (VIDEO)

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

This is the sub-heading.

Belgian offshore construction companies Jan De Nul and DEME, through their consortium TM EDISON, have won the tender for the construction of the Princess Elisabeth Island in their home country and the first artificial energy island in the world.

And this first paragraph outlines the project.

The artificial island, which will be built some 45 kilometres off the Belgian coast and will occupy an area of approximately five hectares above the waterline, will serve as the link between the offshore wind farms in the country’s second, 3.5 GW Princess Elisabeth offshore wind zone and its onshore high-voltage grid.

Initial plans don’t seem to be putting any wind turbines or solar panels on the island.

The most impressive part of the article is the video, which shows how the island will be constructed.

To some people of my age, the construction of the island will seem familiar, as the island will be built in a similar way to the Mulberry harbours of World War II.

A few years ago, I went inside some of the giant Pheonix caissons in The Netherlands, where they were initially used to plug the dykes after the North Sea Flood of 1953. They are now a museum of the floods called the Watersnoodmuseum.

Engineering is repeating itself.

DEME Returns To Scotland, Announces Offshore Wind Industry Firsts

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

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.


  1. The water depth at Moray West wind farm is 35-54 metres, which necessitates the XXL monopiles.
  2. Working offshore in winter can be challenging.
  3. 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!
