Dr. Sanjay Raja Arwade and Dr. Don J. DeGroot, Sc.D., P.E., both professors in the Civil and Environmental Engineering Department, have received a $317,732 grant from the National Science Foundation for a project on wind technology. They are developing models for loading placed on “multiline ring anchors” subjected to wind, waves, and other forces as part of offshore wind development.
According to staff writer Ron Chimelis of the Springfield Republican, “A multiline ring anchor is a ring-shaped anchor designed to be deeply embedded in offshore soils.”
As the UMass News Office reports, the increase in offshore development in wind energy, wave energy, and aquaculture sectors requires multiple, closely spaced platforms that need omnidirectional anchors.
Chimelis adds that “The Arwade-DeGroot configuration differs from typical oil and gas installation for floating drilling platforms. It would allow for the sharing of anchors among multiple platforms, reducing costs for materials, fabrication, and installation.”
Both the Chimelis article and the UMass News Office release note that the researchers will partner with Vryhof Anchors, based in the Netherlands, so that their results are driven by industry needs.
Arwade and DeGroot are also collaborating on the NSF project with researchers at Teas A&M, the University of California Davis, and UMass Dartmouth. (July 2020)
