CTE Wind, global leader in civil engineering for wind turbine foundaiton design, celebrates remarkable growth and presence in 75 countries.

CTE Wind has experienced remarkable growth since its establishment in 2003. Over the past decade, the company’s expansion has been particularly noteworthy. In 2012, CTE Wind successfully implemented projects in 23 countries, including Canada, South Africa, and Greece. France accounted for the majority share of these projects. Presently, CTE Wind has extended its reach to an impressive 75 countries worldwide.

One of CTE Wind’s significant achievements in 2012 was the design and development of the Tarfaya wind farm in Morocco, which was then the largest wind farm in the country. Spanning across 10,000 hectares of land, the Tarfaya wind farm boasts a total capacity of 301 MW and encompasses 131 turbines. This remarkable project played a pivotal role in helping Morocco reduce its reliance on fossil fuels and achieve its renewable energy goals.

The wind energy landscape has undergone substantial transformations in recent years. Not only are wind farms becoming larger in scale, with installations exceeding 150 wind turbines becoming the norm in certain countries, but the wind turbines themselves are also becoming more powerful. In 2012, the average wind turbine had a power rating between 1 and 2 MW. However, today it is more common to see turbines with a capacity of 4 to 6+ MW. Furthermore, there is ongoing development in the industry, with Chinese original equipment manufacturers (OEMs) working on onshore wind turbines that match the power output of offshore generators. It is anticipated that in the near future, we may witness the emergence of turbines with an astounding output of 8 to 10 MW. This progress raises important questions regarding the design and construction of wind turbine foundations. As CTE Wind continues to innovate and expand its presence in the global wind energy market, it remains at the forefront of these advancements, consistently adapting its expertise to meet the evolving needs and challenges of the industry.

CTE Wind commissioned the Spanish University of Burgos to carry out a series of tests with the Soft-Spot™^®. The structural tests are intended to prove once again if and how the resource-saving wind turbine foundation solution for “onshore” wind turbines works.

Burgos (ESP)/La Richardais (FRA) – The University of Burgos was entrusted with testing the patented Soft-Spot™^® foundation solution from CTE Wind Civil Engineering for its functioning and safety at the end of 2021. The results of the test campaign, which ended at the end of May, confirmed what had already been demonstrated from many certification bodies worldwide and in various finite element models (FEM): The Soft-Spot™^® works and is safe.

Gapping occurs later

The Soft-Spot™^® changes the stress distribution on the ground compared to a standard slab foundation. Due to central EPS soft layer, higher soil stresses are applied under the remaining ring.

As a result, a wind turbine with a Soft-Spot™^® foundation will gap much later than a foundation without a soft layer, with the same foundation diameter. This increases the stability.

Over 1000 wind turbines…

…use the Soft-Spot™^® worldwide. The first project with the patented CTE Wind solution has been in place in 2019 in Thailand in a wind farm with 60 turbines. Each turbine has a hub height of 157 meters. Originally, a shallow foundation with 1,192 cubic meters of concrete and a diameter of 27.4 meters was planned.

But the excavation was not allowed to exceed more than 25 meters diagonally. Thanks to the soft layer under the foundation, the diameter could be reduced to 24.5 meters; minus 210 cubic meters of concrete (-18 percent) and 11 tons of reinforcing steel (-9 percent). The certifying body of DNV in Hamburg ensured that everything proceeded correctly and according to international standards during the design phase.

About CTE Wind Civil Engineering and the Soft-Spot™^®

The Soft-Spot™^® was developed by the French company CTE Wind Civil Engineering SAS. CTE Wind is an international engineering company specializing in the design and calculation of onshore foundations for wind turbines. The solution optimizes the existing and well-functioning system of shallow foundations by integrating known knowledge from structural engineering. Thus, a soft layer (EPS) is simply placed under the center of the foundation so that the forces of the wind turbine are transferred into the ground in a ring shape instead of onto the entire surface.

CTE Wind R&D and Consulting services are the first choice when it comes to foundation design regardless of the WTG-manufacturer, model, size, power or soil conditions. Thanks to internal R&D-Team with senior engineers, holding over 100 years of cumulated experience in the design of wind turbine foundations, nothing is impossible.

La Richardais (FRA) – In 2019 Developers worldwide have globally commissioned a little over 45GW of onshore wind turbines. According to Bloomberg New Energy Finance, the Danish firm Vestas remained this way the world’s leading wind turbine supplier, with Spanish-German wind engineering company Siemens Gamesa a strong second. Chinas manufacturer number one Goldwind was third in the rankings, while US-Leader GE Renewable Energy’s secured its fourth place. Together the top four manufacturers accounted for 55 percent of the market share.

100 years of cumulated experience

This statement applies more or less also to CTE Wind, which calculated, designed and evaluated about 5000 WTG-foundations in 2019 around the globe. Thanks to CTE Wind’s internal R&D, with senior engineers holding over 100 years of cumulated experience in the design of wind turbine foundations worldwide, new turbine models from the top manufacturers as well as less common WTG-models from smaller or local manufacturers are only a little challenge. CTE Wind engineering services lead to state-of-the-art foundation solutions for wind turbines. Regardless of whether it is a prototype, such as GE’s giant 12 MW Haliade X or smaller 1 MW machine, from German ENO or Dutch EWT.

Wooden tower

Also worth mentioning: the different types of towers for wind turbines. Concrete (hollow foundation) and steel towers are well known to CTE Wind. Both tower systems are suitable to be used alone or in combination. Even foundations with wooden towers were calculated and designed by CTE Wind in the past. The sum of all experiences made during the projects since 2003 is the reason why their engineering services in foundation design are the first choice for wind turbine manufacturers, wind park developers and EPC contractors worldwide.

A pile foundation transfers the WTG loads to the lower-lying ground, thereby providing an overall support to the structure. Geotechnical experience is a must for designing wind turbine foundation pile. CTE Wind designed piles with length varying from 10 to 70 meters.

Foundation piles transfer loads from the wind turbine foundation to lower-lying ground, thereby providing overall support to the structure. These piles carry concentrated loads and are subject to fatigue. As such, careful assessment of geotechnical conditions and proper interpretation of the soil reports’ drilling logs and laboratory data are critical, which is why CTE Wind has senior geotechnical engineers working on wind farm projects worldwide.

CTE Wind’s pile foundation designs solutions consider driven, bored and drilled piles as well as vibro piles and Franki piles. Once the pile solution has been chosen, the length and diameters, as well as the stiffness of the pile and the loads on top of it have to be determined. The compression, the tensile and the fatigue loads are taken into account to establish the calculation report and the final drawings stating the rebars and concrete volumes.

Piles for intertidal nearshore foundations

In current projects CTE Wind has designed pile foundations with lengths varying from 10 to 70 meters which is exceptional. The latter was designed and built in Asia in different nearshore projects on an intertidal sea-zone. CTE Wind also provided pile designs in Belgium, France, Germany, The Netherlands, Brazil, Serbia, Ukraine, Russia, and Finland to name a few.

CTE Wind designed the deep foundation and anchor cage for a NRG Patagonia wind turbine in Argentina. The 1.5 MW will help Castelli, a town with 10,000 residents, to grow their sustainable energy production.

Buenos Aires (ARG) – Although Argentina’s wind energy has been on hold for a while, there still is a demand for wind industry specialists such as CTE Wind to extend expertise on wind projects. Our sister company, CTE Wind Ibérica, received an interesting request from the Cooperativa de Electricidad Castelli (CUECCA) for a wind energy project located 185 km from the city of Buenos Aires. The cooperative’s main goal is to grow sustainable energy production in Castelli, a smaller town with about 10,000 residents. In striving to meet its goals, CUECCA moved forward to install a 1.5 MW wind turbine from the local WTG manufacturer NRG Patagonia (NRGP).

CTE Wind has been selected by NRGP for the foundation design. Due to the unique soil conditions, a deep foundation with piles was designed. CTE Wind also contributed the optimized design of the anchor cage, providing substantial savings in steel reinforcement. Enrique MARTINEZ, Commercial Manager of CTE Wind Ibérica said: « We are thrilled to work on this project. Even if it is a small project, we want to find the best possible solution for the customer. »

Design and construction in due time

Recently, an important project milestone has been reached: breaking ground and the beginning of the foundation construction. « Every step has been done in due time. This is also one of the reasons why customers keep coming back to CTE Wind», added MARTINEZ.

The 82m rotor for CUECCA´s NRGP 82 was unloaded not long ago in the Port of Zarate, Argentina. The rotor was manufactured in the US. The 82 is the tallest model so far from NRGP with a hub height of 80 meters and a rotor diameter of 82 meters. Soon 4,000 households of Castelli will enjoy green energy from their own wind turbine.
