What are monopiles?

A monopile is a fixed bottom foundation design, which is used primarily for offshore wind projects. Designed using thick & heavy steel plates, the primary materials are joined and rolled into can and cone sections, seamlessly welded together to form a robust steel tubular structure which is driven into the seabed to support the wind turbine generator (WTG). Monopiles are typically the foundation of choice for offshore wind projects, with circa 80% of all operational turbines supported using a monopile foundation. 


Cost Effectiveness and Reliability
Monopiles have a simpler fabrication process compared to other foundations, using a technology driven semi-automated process to create a cost-effective and robust solution for offshore wind turbines.


The newest generation of monopiles are set to be installed into deeper waters supporting the world’s largest turbines in the market.

Proven Track Record
Monopiles have been manufactured and installed successfully in offshore wind projects globally, with their reliability and performance well documented throughout the market.
