Hywind Scotland: The World’s First Floating Wind Farm Undergoes Major Maintenance

Hywind Scotland, a groundbreaking offshore wind farm that floats, is about to have significant maintenance done this year. It’s a first for the industry. Equinor’s 30MW project will stop working for about three to four months while they do this.

Operational Overview

Hywind Scotland has been leading the way in the floating offshore wind farm industry since it started in 2017. It’s positioned off Peterhead in Aberdeenshire, Scotland, where the water is 95 to 120 meters deep. The site has five Siemens Gamesa turbines that can generate up to 30 megawatts (MW) together. That’s enough electricity for around 34,000 homes in the UK.

Remarkable Performance

Equinor, Norway’s energy powerhouse that runs the farm, broadcasted with pride in December 2022 that Hywind Scotland had hit its fifth anniversary. It’s been hailed as the top offshore wind farm globally. With a capacity factor of 54% during its five years, it’s proved to be highly efficient and showed the promise of floating wind tech.

Maintenance Necessity

The decision for maintenance was driven by operational data analysis, which revealed the need for heavy maintenance on the turbines. This marks the first time a floating wind farm will undergo such a comprehensive maintenance operation.

Maintenance Strategy

  • Towing to Norway: The turbines will be towed to Wergeland Port in Norway during the summer months.
  • Collaboration with Siemens Gamesa: The maintenance work will be conducted in close collaboration with Siemens Gamesa, the turbine supplier.
  • Selection of Wergeland Group: Equinor has awarded the contract for onshore works to the Wergeland Group in Gulen, Norway, known for its offshore wind experience and deep water ports capable of servicing these turbines.

Impact and Future Prospects

While the farm will be offline for up to four months, the maintenance work is essential for its long-term performance and reliability. This operation also sets a precedent for future maintenance of floating wind farms, a sector that is expanding rapidly with many larger projects in the pipeline.

Advancing Floating Wind Technology

Hywind Scotland’s success over the past six to seven years has not only demonstrated the high capacity factors achievable by floating wind farms but also paved the way for more ambitious projects in the floating wind sector. Its innovative spar-type substructure and the ability to withstand deep water conditions have been instrumental in proving the viability of floating wind technology.

Industry Significance and Challenges

The upkeep work being done at Hywind Scotland is more than your average fix-up job — it’s a big deal for the sea-based wind power scene. It highlights the quirky hurdles that come with keeping floating windmills in shape, like needing smart repair plans and figuring out how to haul huge blades back to land. What we learn here is gonna be super helpful for up-and-coming offshore breeze ventures, which everyone’s counting on to help switch the world over to greener power.

Environmental Considerations

Maintaining Hywind Scotland isn’t just about the tech or how things run. It’s also big-time about looking after the environment. Keeping nature safe while they do their maintenance work is a top priority for Equinor. They’re all in for protecting the environment, which means they plan things out carefully so fishes and other sea creatures don’t get hassled. Plus, they’re super strict about handling waste right and making sure not to pollute.

Global Impact and Future Developments

The success of Hywind Scotland and its regular upkeep work are making waves beyond its shores, encouraging similar ventures all over the globe. The know-how and insights from this groundbreaking wind farm are priceless. They’re helping to shape the future of other floating wind farms, which are crucial for harnessing wind power in deep waters where those typical turbines that stick to the seabed just won’t work.


Keeping up with the maintenance of Hywind Scotland marks a big leap forward in the development of floating wind farms. This shows how serious the energy sector is about creating sustainable and dependable power. As we shift to greener sources of energy, the insights from taking care of Hywind Scotland will surely shape the offshore wind efforts that come next.
