Experten im Fundament Design für Windturbinen von 1 bis 12 MW.

Laut Bloomberg New Energy Finance werden im Jahr 2019 weltweit mehr als 45 GW Onshore-Windenergie in Betrieb genommen. CTE Wind hat fast 1.500 WTG-Fundamente weltweit entworfen, optimiert oder geprüft, was etwa 5 GW der installierten Onshore-Windenergieleistung im Jahr 2019 entspricht. Ein gutes Ergebnis für die 30 Ingenieure, die weltweit zusammenarbeiten. CTE Wind ist ein internationales Ingenieurberatungsunternehmen mit Hauptsitz in Frankreich, das sich auf die Analyse und das Design von Onshore-Windenergieanlagen spezialisiert hat. Die Ingenieurdienstleistungen führen zu innovativen Lösungen für die Gründung von Windkraftanlagen. In Rotterdam haben sie das Fundament für die riesige 12 MW Haliade X von GE entworfen. Aber auch mit kleineren 1-MW-Anlagen auf Holztürmen sind sie vertraut. „Dank unserer erfahrenen Bauingenieure, Tragwerksplaner und Geotechniker ist es für uns nur eine kleine Herausforderung, Fundamente für Windkraftanlagen auf der ganzen Welt zu entwerfen“, sagt Alexander Martin, CEO von CTE Wind International. „Dabei spielt es keine Rolle, ob es sich um neue Turbinenmodelle führender Hersteller oder um weniger verbreitete WTG-Modelle kleinerer oder lokaler Hersteller handelt“, fügte er hinzu.

Grösste Windparks in Frankreich, Polen und Spanien

Die Summe der seit 2003 gesammelten Erfahrungen ist der Grund, warum das Ingenieurteam von CTE Wind mit Niederlassungen in Brasilien, Polen, Portugal, Spanien, USA und Asia oft die erste Wahl für OEMs, Windparkentwickler und EPC/BoP-Auftragnehmer ist. „Auf diese Weise haben wir mehr als 17.500 Windenergieanlagen in 67 Ländern ohne einen einzigen Ausfall errichtet“, so MARTIN weiter. Eines der Hauptziele von CTE Wind ist es, Fundamentkonstruktionen anzubieten, die den Einsatz von Ressourcen optimieren und dabei helfen, Beton und Bewehrungsstahl einzusparen. Eine solche Lösung ist der patentierte SOFT-SPOT®, ein Schwerkraftfundament mit einer weichen Schicht unter dem Ankerkorb. Jedes Projekt erhält eine auf die spezifischen Bodenverhältnisse zugeschnittene Konstruktionslösung. In Finnland hat CTE Wind eine Lösung mit einem Felsanker entwickelt, während die Ingenieure gleichzeitig eine nahe gelegene Gründung im Mekong-Delta in Asia entworfen haben. „Das Vertrauen unserer Kunden führt dazu, dass wir nicht nur spezielle und neue Lösungen entwickeln, sondern auch die Fundamente für die größten Windparks in Frankreich, Spanien und Polen bauen. Wir freuen uns, wenn wir bei einem Windparkprojekt eine wichtige Rolle spielen können. Das zeigt das Vertrauen unserer Kunden in unsere Konstruktionen und ist für uns ein Ansporn, weiterhin gute Leistungen zu erbringen“, schließt er.

«To work with CTE Wind as designer was nice. The speed of response and reliability of the planning has been a winning experience for us.»

Arjan Louwerse from H4a Windenergie B.V.

Coöperatie Zuidenwind has poured the concrete for the foundation in Heibloem in the Netherlands and created the basis for the installation of their wind turbines. The foundation design and calculation for this project was done by CTE Wind Civil Engineering. The expert in foundation design WTG suggested their Soft-Spot® instead of a typical pile foundation.

Heibloem (NL) / La Richardais (FR) – The Netherlands soil consistsof unconsolidated, very young sediments. Due to the proximity of the low-lying part of the European continent, the basin of the North Sea, the bottom rarely rises higher than 30 m above sea level. In the areas along the coast (provinces of Groningen, Friesland, Noord-Holland, Zuid-Holland, Zeeland) the surface soil layers consist mainly of clay deposits. In the west of the Netherlands the clays are replaced by lowland moors (peat). To sum up: in the Netherlands, pile foundations are mandatory for wind turbines because of the concentrated forces occurring on little surface area. Except in Heibloem, where the ground is exceptionally stable. So good, in fact, that CTE Wind offered its resource-saving Soft-Spot® instead of the usual foundation.

Soft-Spot® in the Netherlands

The Soft-Spot® was developed by CTE Wind’s engineering team and is implemented in various countries around the world. «It was simply the most economical foundation we could choose », Arjan Louwerse from H4a Windenergie B.V. says. He is the project manager for Coöperatie Zuidenwind wind turbines. This foundation design optimizes the use of resources and helps to save up to 15 % of concrete and 2 to 5 % of reinforcement steel. In some cases what is even more important than the costs is the available space : with Soft-Spot® you need less surface for the foundation. This reduces the time and excavation costs. «The philosophy to reduce the costs of the Soft-Spot® was also a good point of discussion with our client. From the beginning we had a good feeling with the design», he explains.

In fact thanks to the new design the outer diameter of the foundation was 1.1m smaller compared to a typical foundation design. This resulted in a reduction of 11 % of concrete and 3 % of steel – or more precisely about 100m3 of reinforced concrete. «To work with CTE Wind as designer was nice. The speed of response and reliability of the planning has been a winning experience for us», Louwerse added. In spring 2020 the wind turbine will arrive together with the largest blades ever installed onshore in the Netherlands. (ctewind)

In the last 2 years over 50 project developers trusted CTE Wind’s Soft-spot^® solution. Recently in Spain the expert of wind turbine foundations has won their third project, where the Soft-spot^® solution was implemented.

Bilbao (Esp) / La Richardais (FRA) – CTE Wind Ibérica has won again a contract in Spain to calculate and design foundations with its Soft-spot^® solution. This is an important milestone for CTE Wind International as now three wind farms on the Iberian Peninsula will take advantage of its cost saving design. In addition to these projects, CTE Wind’s clients are also adopting this solution in many other wind farms worldwide. Argentina, Brazil, Chile, France, Lithuania, Indonesia, Mexico, the Netherlands, Russia, Serbia, Sweden and Thailand to name a few. Over 50 wind farms around the globe, 750 wind turbines are using this resource saving solution which was introduced a while ago by CTE Wind.

« CTE Wind is proud of the confidence shown by its clients, and especially of the interest on applying the Soft-spot^® solution», Chief executive Alexander MARTIN said and added « Our design provides interesting advantages and cost saving in material consumption and civil works while being easy to be built. »

Simply the most economical foundation

The Soft-spot^® was developed by CTE Wind’s engineering team and is implemented in various countries around the world. As a result of his astonishing design this solution allows savings in concrete volume up to 15%, reduction of foundation diameter and total weight reduction of reinforcement bars of 7 to 9%. The earthwork to be handled is reduced too. In some cases, what is also important is the available space : with Soft-spot^® you need less surface for the foundation. The construction is very easy and the material for the soft layer can be easily purchased for a low price all over the world.
