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.
