Entrion Wind Launches ENOVA-Supported Feasibility Study to De-Risk and Reduce Costs for FRP Monopile Offshore Wind Foundations

Entrion Wind has launched an ENOVA-supported technical and commercial feasibility study evaluating the potential to reduce costs associated with Fully Restrained Platform (FRP) monopile foundation technology for offshore wind installations in water depths between 55 and 80 meters. The study focuses on systematically de-risking the technology through validated engineering analysis while identifying pathways for improved cost efficiency and future commercial deployment.

The project addresses a central challenge in offshore wind development: enabling cost-effective expansion into deeper waters. By combining advanced load analysis, geotechnical assessment, and installation concept evaluation, the study establishes a robust technical basis for future investment and development decisions related to FRP monopile foundations.

Entrion Wind serves as responsible project manager, coordinating a multidisciplinary consortium of experienced technology providers and stakeholders across offshore wind development, manufacturing, transport and installation, analytics, and environmental assessment. The work emphasizes transparency, data-driven validation, and alignment with established offshore engineering standards.

Jon Høvik, Vice President of Engineering at Entrion Wind and Project Manager for the ENOVA study, said:

“This project is about replacing uncertainty with data. With ENOVA’s support, we are applying rigorous engineering analysis to evaluate FRP monopile technology as both a technical and commercial alternative for deeper-water offshore wind. Our objective is to provide a clear, credible foundation for future decision-making—particularly where cost reduction and risk management are critical.”

C2WIND plays a key role in the project, providing specialist expertise in advanced load analysis, technical benchmarking, and evaluation of conceptual FRP monopile solutions. Their contribution supports accurate modelling, thorough documentation, and independent assessment of structural performance under offshore conditions.

Christian Berg Mørch, CEO of C2WIND, said:

“The ENOVA project allows us to apply advanced load analysis and benchmarking to an emerging foundation concept with significant potential. Our role is to challenge assumptions, validate performance, and ensure that conclusions are grounded in robust engineering. This work is an important step in maturing FRP monopile technology toward deployment decisions.”

The study establishes a design basis for key FRP components, including monopile design informed by global motion analysis and detailed geotechnical surveys. It also evaluates mooring concepts adapted to site-specific seabed conditions and provides cost estimates covering fabrication, transport, and installation.

According to ENOVA’s published project information, the FRP monopile technology has reached Technology Readiness Level (TRL) 6 and represents an internationally patented system expected to be introduced and commercialised in Norway and internationally from 2027. The results of this feasibility study will inform subsequent qualification processes and future offshore wind licence development decisions.
