Brief 

Holcim and ECOncrete, in coordination with the New York State Department of Environmental Conservation, have implemented a novel ecological scour protection system for offshore wind projects off the coast of Long Island, N.Y. The system features eco-friendly concrete units that minimize material use and marine habitat disruption.

 

Insight

Successful deployment of the novel Droplock Ecological Scour Protection is completed 12 miles off the shore of Long Island, NY in coordination with the New York State Department of Environmental Conservation. Approximately 4,000 concrete units were manufactured earlier in August in New York.

  • First and only structural solution to benefit both foundation resiliency and local marine ecosystem.
  • Over 1000 t of bio-enhancing Droplock and rock-material for scour protection – off Long Island, NY at a depth of more than 100ft.
  • Two-year ecological monitoring to set new standards in responsible marine construction.

 

The two-year joint R&D project to provide offshore wind projects with ecological scour protection began in May 2021 and is funded by the Binational Industrial Research and Development (BIRD) Energy Foundation with the participation of the US Department of Energy.

The project partners are ECOncrete Tech Ltd., global provider for bio-enhancing concrete technology, and Holcim US, the country’s leading cement producer. Together, they are redefining offshore scour protection through the development of a novel concrete unit that requires up to 30% less material, minimises native habitat degradation, and supports ecological uplift in offshore wind projects.

“The unit’s ecological properties mimic natural marine habitats’ features while providing the armoring functionality required for scour protection”, said Dr. Ido Sella, CEO and Co-Founder at ECOncrete Tech. “Offshore wind projects that integrate nature inclusive technologies are able to gain ecosystem services not achievable before.

The ecological uplift and long-term functionality of ecologically sensitive solutions can mitigate some of the associated impacts of offshore infrastructure. The ecological performance will be verified through comprehensive scientific monitoring comparing the bio-enhanced system to the standard rock-based scour protection to set new industry standards for responsible construction.”
