Industrial & energy-producing structures
As a specialist of structural systems and ground engineering, we provide bespoke solutions combining design and methods, in-house systems and project execution for the construction of industrial and energy-producing structures worldwide.
We deliver bespoke inspections, preservation plans and maintenance operations to manage the ageing of structures and optimize their safety, durability and asset value.
As specialists of structural components, we specialise in the repair or replacement of parts of an asset that are essential to guarantee continued safe use. The repair or replacement of parts of an asset due to structural deterioration is essential to maintain or reinstate it in a condition that guarantees continued safe use. As specialists of structural components, VSL helps owners and asset managers to define a tailored-made solution balancing cost, safety, continuity of service, performance and durability.
We offer structural modification solutions to accommodate new uses or requirements that help maintain a structure’s value, comply with the latest design codes and safety recommendations or answer to new needs.
Post-tensioned concrete wind tower: What is at stake?
The wind market is evolving very quickly, with towers becoming ever higher and stronger to support larger rotors in order to capture more wind. Concrete and hybrid towers have therefore emerged as an alternative to traditional steel towers, thanks to their durability, stability and high structural damping. The post-tensioning system in concrete wind towers is in turn a key element for ensuring the stability and durability of the overall structure.
How VSL can help you
VSL is an expert in post-tensioning systems and their application in wind towers. We understand the critical function of these elements – in particular with a view to durability – and can fully optimize their incorporation into the overall structure and the specific technical requirements.
VSL uses its proprietary post-tensioning technologies: we have developed an external post-tensioning system specifically for wind towers and this has obtained European Technical Approval (ETA). Made of multi-strand vertical tendons, it is a versatile and reliable post-tensioning system that maximizes the use of local resources and ensures reliable structural behavior of the tower throughout its service life, while allowing re-stressing and de-stressing of the tendons if necessary.
We have also developed bespoke post-tensioning systems for offshore wind towers and foundations.
What are the VSL post-tensioned concrete wind tower solutions?
A full installation package: design, supply and installation on site including the related site logistics and, where necessary, on-site prefabrication of the systems using local resources.
