Entrion Wind Achieves DNV Statement of Feasibility for Top Mooring Assembly (TMA) Monopile Technology

KRISTIANSAND, NORWAY – Entrion Wind announced today that its patented Top Mooring Assembly (TMA) concept has successfully completed the Technology Qualification (TQ) process and has received a formal Statement of Feasibility from DNV, one of the world’s leading certifiers of renewable technologies.

This achievement affirms the performance and reliability of the TMA—a key component of the company’s Fully Restrained Platform (FRP) monopile technology, designed to extend the capabilities of monopile foundations into deeper waters with favorable economics. It marks a significant step forward in the journey toward commercial deployment of the FRP monopile system.

The Statement of Feasibility was awarded following a comprehensive evaluation under DNV-SE-0160, passing a rigorous vetting process for qualifying novel technologies for offshore use. This milestone follows an earlier certification awarded by DNV in 2023 for the FRP monopile concept and provides continued validation of Entrion Wind’s technology.

It also marks the beginning of the next phase: Qualification Execution, where practical implementation and alignment with identified standards will continue under the guidelines of the accepted Qualification Plan.

“We are proud to receive this certification,” said Li Lee, Co-founder and VP of Research & Development at Entrion Wind. “This Statement of Feasibility from a respected institution like DNV reinforces the strength of our engineering approach and brings us one step closer to delivering scalable solutions for deep-water offshore wind.”

The FRP monopile leverages proven technologies to bring the favorable economics of monopile foundations into deeper waters. The TMA is a critical component in making this possible. Designed to connect mooring lines to the FRP monopile and allow for adjustment of tension, the TMA enhances structural stiffness. It helps the system resist overturning moments from wind, waves, and current—without compromising installation or operational efficiency. 

Entrion Wind continues to advance the FRP monopile system through feasibility studies, testing programs, and strategic industry partnerships. Developers are invited to explore site-specific implementation, evaluate LCOE impacts, and participate in full-scale or retrofit demonstration opportunities as the technology progresses through its development roadmap.

Commercial deployment of the FRP monopile system is planned for 2028.
