How PPG Helped Protect the Hornsea One Offshore Wind Farm

Project: Hornsea One Offshore Wind Farm
Location: North Sea, UK
Coating System: PPG SIGMACOVER 850 with a durable polyurethane topcoat
Application: Offshore wind turbine structures

Offshore wind farms operate in some of the most challenging environments imaginable.

Constant exposure to seawater, salt spray, wind and harsh weather means that protecting the steel structures supporting offshore wind turbines is critical to long-term performance.

Hornsea One, located in the North Sea, is one of the world's major offshore wind farms. Its location presented a significant challenge for corrosion protection, requiring a coating system capable of performing across atmospheric, splash and immersion zones.

The Challenge

Offshore structures are exposed to highly aggressive environments, making corrosion protection a major consideration throughout their service life.

For Hornsea One, the protective coating system needed to provide reliable performance across different exposure zones while supporting the long-term durability of the wind farm infrastructure.

The Solution

PPG proposed a system featuring SIGMACOVER 850 as a key component.

The system was designed to provide tough protection across atmospheric, splash and immersion zones, combined with a durable polyurethane topcoat.

The Result

The coating system provided a robust solution for protecting offshore wind infrastructure in the demanding North Sea environment.

As offshore wind continues to expand, projects such as Hornsea One demonstrate the important role protective coatings play in extending the service life of renewable energy infrastructure.

From bridges to offshore wind turbines, the right coating system can make a huge difference to the long-term performance of steel assets.
