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.
We are happy to announce our participation at the upcoming wind event in Hanoi. The CEO, Alexander Martin, and the head of our Vietnamese office will be giving a presentation regarding international foundation design experience and near-shore solutions. We are looking forward to seeing you there!

Nearshore foundation – New platform design allows up to 30 percent savings×
Hanoi (VNM) /La Richardais (FRA) – A new design of a nearshore foundation for wind turbine generator has been finalized by CTV, a branch of CTE WIND group at the end of September 2019. The project is located in the East Vietnam sea and allows to save 30 percent of the construction costs compared to similar projects due to the astonishing design of the foundation.
For a 4 MW wind turbine above the platform, CTE Wind has designed a foundation with 520m3 of concrete, 120 tons of steel and 46 piles. The piles have an average length of 70 meters and are hammered into the muddy nearshore underground. In fact, the geotechnics were very challenging and the piles were also designed in-house to withstand tides, waves and ship movements close to the platforms.

Soft-Spot® Solution – Foundation Design Helps To Save Resources
«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)
