Zoom Webinar , Online, WA CIA

Overview

In this seminar, our speakers will provide an insight into the construction of concrete foundations for Wind Turbine Generator (WTG) foundations.  Given the move towards greener energy sources, wind farms have grown in popularity over the years with more than 35% of the clean energy in Australia coming from wind generation in 2019 and the Clean Energy Council noting wind power as the cheapest source of large-scale renewable energy. These projects are generally in remote areas and involve the use of mobile batch plants.

An Introduction to Wind Turbine Generator (WTG) Foundations (presented by Joel Brown)

Given the move towards greener energy sources, wind farms have grown in popularity over the years with wind power now being considered as the cheapest source of large-scale renewable energy.  This presentation aims to provide an overview on the design of wind turbine generator foundations and the common challenges encountered when constructing them.  The topics covered in this presentation are easily transferred to other projects which involve deep concrete pours, or projects in a rural area.  Come for an introduction to this interesting and emerging market. 


With evolving technology brings bigger turbines, leading to larger foundations. Pours are regularly over 600 m3 for a single footing and could soon be in the order of 1000 m3. With this comes several challenges with both the design and physical construction. It is these challenges which will be explored more in-depth in this session. High strength grouts are commonly used to assist in transferring the loads from the steel tower and into the concrete foundation, and these products suffer from the same challenges as the foundation pours. These specialist grout products require care and experience to place correctly. This seminar will cover the key factors which affect the grout performance, including mixing ratios, on-site temperatures and wind speeds when pouring. The nuances of these projects are often misunderstood and can lead to long term maintenance requirements and in the worst case, demolition and reconstruction of foundations or grout pockets. We aim to give you the tools to avoid this!

 
“Wind Farm Grouting – How Hard Can it Be?” (presented by Thomas Bak )
 
  • What is grouting in a wind tower foundation and its purpose
  • Anchor cage pocket vs grout ridge above concrete design – pros and cons and lessons learned over the last 25 years
  • Sealing and its impact on the total life-cycle cost
