Enhanced Foundation Solutions for Wind Turbine Generators
Total Ground Engineering (TGE) is at the forefront of designing specialized foundations for Wind Turbine Generators (WTGs) across a comprehensive spectrum of turbine sizes, hub heights, and challenging ground conditions.
Our solutions empower Owners, Balance of Plant (BOP) Contractors, Funders, and Insurers to enhance foundation performance and effectively manage risks.
With our deep expertise in ground engineering, soil-structure interaction, and complex foundation design, TGE are your trusted partner in achieving operational excellence, risk mitigation and sustainability in renewable energy projects.
Our Expert Services Include
WTG Foundation Design
Tailored foundation solutions that meet specific project requirements.
Construction Observation and Validation Ensuring compliance with design specifications throughout the construction phase.
Design Review and Risk Assurance
Expert review for Owners, Funders, and Insurers throughout the project life cycle to verify design integrity and performance.
Portfolio Audit
Assessments for existing WTG foundations, providing insights into risk profiles and mitigation strategies.
Addressing Rotational Stiffness Challenges
As WTGs evolve with taller towers and larger turbines, achieving optimal rotational stiffness becomes crucial. Our advanced analytical techniques delve deep into the soil-structure interactions essential for supporting these structures. Our innovative foundation designs not only meet key operational performance requirements but also offer significant advantages:
Reduction of Embedded Carbon
Reduce embedded carbon by up to 45%* compared to traditional foundations.
Cost Efficiency
Lower construction and material costs by up to 30%*.
Enhanced Performance Metrics
Significantly improve key performance criteria such as rotational stiffness.
*Based on comparison studies between existing gravity pads and Turris™ micropiled foundations.
