Nabrawind teams up with AIN to develop his Nabranested technology

Nabranested is a new tubular tower concept whose section can be transported nested together like a matryoshka doll.

This new generation of towers will result in up to an 80% reduction in logistics volume as well as in a 40%-60% decrease in CO₂ emissions for road transport.

Nabrawind and the Navarre Industry Association (AIN) have joined forces in the Nabranested project, a pioneering R&D initiative that marks a turning point in wind tower transport. The goal: to design and validate a new generation of tubular towers capable of nesting within one another during transport, dramatically reducing both logistical costs and associated emissions.

Thanks to this innovative concept, an entire tower can be transported in a single shipment, occupying the same space as only one of its sections. This will result in up to an 80% reduction in logistics volume and a 40–60% decrease in CO₂ emissions for road transport, directly contributing to the carbon-neutrality objectives of the European Green Deal.

Disruptive technology with built-in structural self-diagnosis

In addition to its nested design, Nabranested will integrate a real-time monitoring and self-diagnostic system powered by artificial intelligence, developed by AIN. This system will enable continuous supervision of the structural integrity of tower sections during transport and operation, detecting any deformations or damage that could compromise safety.

The project also includes maintenance-free bolted joints, eliminating the need for regular inspections, and a new modular internal design that allows for on-site installation, reducing assembly time and improving operational efficiency.

Boosting the competitiveness of the wind industry

Nabranested addresses one of the greatest challenges currently facing the wind sector: the transport and installation of increasingly large wind turbines. This breakthrough will enable manufacturers and developers to cut costs, speed up project deployment and enhance sustainability across the entire value chain, strengthening the competitiveness of wind power against other energy sources.

In addition, Nabrawind plans to protect the technology through an international patent, further reinforcing its leadership as a global innovator in advanced wind technologies.

This project has received funding from the Government of Navarra and the European Regional Development Fund (ERDF).
