Onshore Wind Turbine Foundation Design

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.
