Offshore wind technology firm Entrion Wind has received a second international patent for its Fully Restrained Platform (FRP) monopile design, aimed at enabling offshore wind deployment in deeper waters.
The latest patent was granted by the Norwegian Industrial Property Office (NIPO), marking a further step in Entrion Wind’s effort to expand the application of cost-effective monopile foundations beyond current depth limitations. The company had previously secured a patent from the United States Patent and Trademark Office in October 2024.
“This recognition from NIPO reinforces the strength of our engineering and the growing relevance of the FRP monopile in global offshore wind,” said Jon Hovik, vice president of engineering and operations at Entrion Wind.
The FRP monopile design allows for installation at depths of up to 120 metres, significantly extending the range of traditional monopile foundations. At the core of the technology is the company’s proprietary Top Mooring Assembly (TMA), which is designed to enhance lateral stiffness and platform stability while maintaining simplicity in installation and maintenance.
According to Entrion Wind, the system uses existing technologies and established supply chains to ensure the platform remains cost-effective and scalable. “Our technology addresses a critical industry need – enabling the use of cost-effective monopiles at much greater depths than previously possible,” Hovik added.
The company is currently conducting field demonstrations and feasibility studies in partnership with offshore developers to evaluate the technology’s site-specific performance, its impact on levelised cost of electricity (LCOE), and potential project risks.
Entrion Wind plans to commercially launch the FRP monopile in 2027, with a target of deploying 750 megawatts (MW) annually by 2030. Four additional patent applications are still pending in other jurisdictions.
