RRC Reveals New Braced Tube Foundation Design at Upcoming CLEANPOWER 2023 

Posted by RRC on
RRC Power & Energy is proud to announce the debut of its brand-new Braced Tube design, an important advancement in wind turbine generator (WTG) foundation design technology that is now available for implementation and construction for wind energy projects nationwide. The Braced Tube design is patented under US law. It utilizes bracing shallow beams, which enhance lateral support, a deep tube portion, improved geotechnical verification procedures during construction, and a tapered excavation option that uses less lean concrete. With reduced material requirements for rebar and concrete and shorter concrete placement durations, the Braced Tube Foundation can be completed under a shorter construction timeline and with less labor force needed to build, potentially resulting in substantial project cost savings. Through extensive analysis via industry-leading engineers and state-of-the-art testing facilities, the Braced Tube design has been proven to perform with an extraordinarily high degree of safety. It is a deep foundation – over twice as deep as a typical gravity foundation – with patented bracing beams and a tapered shape. These characteristics contribute to its highly stable and reliable structure that is material-efficient.  The Braced Tube Foundation typically saves approximately 20% to 30% of concrete and rebar/steel quantities compared to a typical gravity foundation. These material savings percentages increase in higher capacity and taller turbines. In addition, the Braced Tube foundation has a smaller diameter than the gravity foundation, creating less environmental impact. Before, during, and after construction, RRC engineers and qualified on-site personnel undertake batteries of tests on the Braced Tube Foundation, including, among others, extensive geotechnical engineering subsurface investigations and advanced laboratory evaluations, to ensure successful, safe construction as well as minimal impact on the surrounding lands. RRC’s senior leadership, including the company’s founder and President Bill Bong, plans to unveil this new design at the CLEANPOWER 2023 Conference & Exhibition in New Orleans, Louisiana, May 22-25. RRC’s experts will conduct open presentations of the new design at 2:00 PM on Tuesday, May 23, and Wednesday, May 24, in booth #4158. Delegates may RSVP to one of the sessions here. Attendees may also stop by RRC’s booth any time to get more information on the patented Braced Tube Foundation design and how it can be harnessed for their upcoming wind energy projects.
