The Offshore Renewable Energy (ORE) Catapult has signed an agreement with wind engineering specialist Bladena – a RES company – to test blade reinforcement technology designed to extend the operational life of offshore wind turbines.

With many of the first fleet of operational offshore wind turbines approaching the end of their planned lifespans, there is a need to accelerate the development of new technology which could potentially help extend the life of turbine blades.

The full-scale testing programme at ORE Catapult’s National Renewable Energy Centre in Blyth will use an 88-metre blade to carry out unique full-scale torsional load tests – the first of its kind conducted by ORE Catapult and understood to be an industry first. It will be used to show how Bladena’s reinforcement technology performs under the twisting forces it could experience out at sea.

ORE Catapult will be developing a bespoke test methodology for this programme, with the aim of better understanding how the new reinforcement technology developed by Bladena impacts how the blade responds. Findings could potentially guide industry-wide efforts to improve turbine reliability and reduce lifecycle costs.

Matthew Hadden, Chief Blade Engineer at ORE Catapult, said: “We’re excited to be carrying out this testing with colleagues from Bladena, to examine how we can aid learning of how to better monitor turbine blades as they age through their operational life, with the hope of being able to inform the development of technological solutions across the sector.”

Bladena, part of RES, the world’s largest independent renewable company, is a specialist in wind turbine-blade engineering and lifecycle solutions.

Find Mølholt Jensen, CTO and Founder of Bladena, said: “Testing our technology at ORE Catapult’s world-class facility is a significant milestone in extending turbine lifespans. Stronger blades mean lower costs and more power, and by improving how they withstand stress over time, we can ensure more reliable performance in offshore environments.”

This project builds on years of research by Bladena and partners, including the Technical University of Denmark (DTU) and the Danish Energy Technology Development and Demonstration Programme (EUDP). Their work revealed how even minor torsional loads can accelerate fatigue in composite materials and adhesive joints.

Testing begins January 2026, with preparations already underway.

Further details on Bladena’s technology will be shared early next year.

London, 29 November 2024 – RES, the world’s largest independent renewables company, has acquired Danish wind turbine blade engineering specialist, Bladena, further strengthening its suite of advanced digital solutions.

Established in Denmark in 2011, Bladena provides engineering expertise to minimise the risk of blade failures for wind farm owners through the entire lifetime of a wind turbine blade. These include proprietary technologies including D-String®, D-TE™, X-Stiffener™, and The RTZ Solution™ that can identify, assess and address blade issues and extend asset lifetimes.

Turbine blades account for approximately 27% of unplanned wind energy O&M costs, and with modern blades exceeding 60 metres in length and their numbers expected to triple over the next decade, addressing early lifecycle challenges is critical to extend turbine asset lifecycles and improve operational reliability. 

The acquisition follows closely behind RES’ recent integration with Swiss drone inspection company, Sulzer Schmid, and further strengthens its digital solutions and services businesses.  

Eduardo Medina, CEO RES, said: “As we continue to grow, we remain committed to bringing in technologies that provide value to our customers around the world. Acquiring Bladena is a significant step forward for RES as we scale and equip our business to meet growing market demand for digital services and blade maintenance. I look forward to welcoming our new colleagues as we continue our mission to deliver affordable zero carbon energy to communities around the world.”

Arun Narayanan, Digital Solutions CEO, RES added: “Through Bladena we will add industry leading blade technology and engineering expertise to our existing range of solutions such as AnemoLive, AeroUp and TuneUp, which have been shown to drive increased annual energy production. Our customers will now be able to better manage blades and improve turbine reliability, helping reduce costs, enhance revenue, and maximise the value of their investments.”

RES currently supports 41GW of operational assets globally, and over its 40+ year history has developed and/or constructed over 26GW of renewable assets – enough to power 25 million homes for a year.  Through the recent acquisitions of Ingeteam and Sulzer Schmid, RES has an enhanced digital solutions and services offering that will serve current and future customers. The company has a development pipeline of 22GW across a range of renewable technologies, due to come to market within the next five years.
