Experts in Foundation Design

From 1 to 12 MW wind turbines

According to Bloomberg New Energy Finance in 2019 developers worldwide have globally
commissioned a little over 45GW of onshore wind turbines. CTE Wind designed, valueengineered
or peer-reviewed foundations close to 1,500 WTG-foundations around the globe,
which represents around 5 GW of the installed onshore wind energy in 2019. A good result
for the 30 engineers working together worldwide. CTE Wind is an international engineering
consulting firm, headquartered in France, and specialized in the analysis and design of
onshore wind turbine foundations. Its engineering services lead to inventive foundation
solutions for wind turbines. In Rotterdam, they have designed the foundation for GE’s giant
12 MW Haliade X. But they are also with familiar with smaller 1 MW machines carried by
wooden towers. «Thanks to our experienced civil, structural and geotechnical senior
engineers the design of those wind turbine foundations worldwide are only a little challenge
to us», said Alexander MARTIN, CEO of CTE Wind International, «regardless if it is for new
turbine models from the top manufacturers or less common WTG-models from smaller or
local manufacturers», he added.

Biggest wind park in France, Poland and Spain

The sum of all experiences made since 2003 is the reason why CTE Wind’s engineering
team with offices in Brazil, Poland, Portugal, Spain, USA and Asia are often the first
choice for OEMS, wind park developers and EPC/BoP contractors. «That is how we
achieved to do over 17,500 wind turbines in 67 countries and without any failures», continues
MARTIN. One of CTE Winds main goals is to deliver foundation designs that optimizes the
use of resources and help to save concrete and reinforcement steel. Such a solution is the
patented SOFT-SPOT®, a gravity foundation with a soft layer under the anchor cage. Each
project receives an adapted design solution to the specific soil conditions. In Finland CTE
Wind designed a rock anchor solution when its engineers also designed a near-shore
foundation in Asias Mekong-Delta. «The trust of our customers leads us not only to
design special and new solutions but also the foundations for the biggest wind parks in
France, Spain and Poland. We are thrilled when we can play an important role in a wind farm
project. This shows the confidence of our customers in our designs and is also an
encouragement for us to continue to perform well», he ends.

Porto Alegre (BRA) – CTE WIND Brasil, part of CTE Wind International, has been active in the Brazilian market since 2005. After 2.5 GW installed wind turbine power or over 1000 designed, value-engineered or peer-reviewed foundations the next years highlight will be the consolidation of the patented Soft-Spot® solution in the Brazilian market. The result of the astonishing solution is the significant optimization of the bill of quantities compared to a standard gravity foundation: Savings in concrete, decrease of the foundation diameter (less earthwork) and total weight reduction of reinforcement bars.

The Soft-spot® is implemented in various countries around the world. Over 50 wind farms around the globe, 750 wind turbines are using this resource saving solution. Argentina, Chile, France, Lithuania, Indonesia, Mexico, Netherland, Russia, Serbia, Sweden Thailand and Brazil. With two new projects, one under development in the state of Bahia with 52 foundations scheduled for construction in early 2021, and an other already finished wind farm with 37 Vestas wind turbines V150 4.2MW in Rio Grande do Norte, things are on his best way to accomplish CTE Winds goals to be responsive, efficient and reliable worldwide.

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.

We are pleased to announce our participation at RAWI FORUM 2020, taking place from February 19th to 20th in Moscow, Russia. Over 300+ participants are expected.

BUILDING A NEW INDUSTRY TOGETHER

CTP Director and Senior Engineer Dariusz KRASOWSKI and CTE Wind International Business Developer Sergio CARÈ-LUCAS will attend the most important Russian forum to discuss about key trends of wind energy market in Russia.
This is a great opportunity for interested companies and experts to meet our dedicated sales team to learn more about CTE Wind’s civil engineering and foundation expertise and to talk about future business opportunities.

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.
