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.

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.

  1. The TetraSub seems to have been designed for ease of manufacture.
  2. One if the aims appears to be to build a strong local supply chain.
  3. The TetraSub was designed with the help of Edinburgh University.
  4. The TetraSpar Demonstrator is in operation off the coast of Norway.
  5. This page on Mission Innovation describes the TetraSpar in detail.
  6. The TetraSpar foundation, owned by Shell, TEPCO RP, RWE, and Stiesdal.
  7. It can be deployed in water with a depth of up to 200 metres.
  8. Currently, they carry a 3.6 MW turbine.
  9. 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.
