Projects
On this page, you can explore Stonereefs’ installations across Denmark. Each project represents a collaboration between municipalities, organizations, and researchers working to strengthen marine biodiversity. The overview highlights where reef modules have been installed, who we’ve partnered with, and how each site contributes to healthier and more diverse marine environments.

2024 Naturpark Lillebælt – Kanalbyen Fredericia
Naturpark Lillebælt (client) Fredericia Kommune (client) Anemo Robotics (Monitoring)
Number of reef modules:
8 by schoolchildren, 14 by Stonereefs
In collaboration between Naturpark Lillebælt and Fredericia Kommune, a total of 22 reef modules have been installed in Kanalbyen in Fredericia. Eight of the modules were designed by local schoolchildren and depict sea animals such as dolphins, fish, crabs, and octopuses. The project is monitored by Anemo Robotics through video, which can be seen here:

2025 WWF – Sundkajen
WWF (initiator and client) Københavns Kommune (owner of installation location)
Number of reef modules:
51
In this project, Stonereefs, together with marine biologists from WWF, has designed a series of reef modules aimed at specific marine species in Øresund. The modules create very specific habitats intended to strengthen the conditions for targeted species in the ecosystem. The modules are installed at Sundkaj in Copenhagen.

2025 Ørsted – Studstrupværket
Ørsted (client) WSP (Monitoring)
Number of reef modules:
40
As part of Ørsted’s biodiversity strategy, they aim to improve biodiversity around their infrastructure projects. In this context, 40 reef modules have been installed at Studstrupværket’s harbour. The project’s setup mirrors that of the International School installation, allowing for comparison of results.
