Projects

Stubbekøbing, Denmark 2026

A configuration of 100 reefs, mixing boulder reefs and reef tiles were installed in Stubbekøbing Havn, in July 2026.

Underwater monitoring cameras were initially installed to establish a baseline of existing marine biodiversity, providing a point of comparison for measuring how ecosystems evolve once the artificial reefs are in place. The monitoring will continue for a year.

Baseline Deployment

Reef Deployment

The project aimed to assess the suitability of the tiles as artificial structures upon which kelp spores and sporophytes could settle, establish and anchor successfully.

30 mini ReefTiles in biomaterial were placed in different tanks to asses different densitities, they were daily monitored, weight and checked for degradation.

Ardfern, Scotland 2026

With Seawilding, 30 temporary artificial oyster reef modules made in proprietary marine-based material, were installed in Loch Craignish. Over the following year, we will assess the survival and growth rates of oysters attached to our reefs compared to oysters on the seabed to assess the suitability of our reefs for oyster restoration.

Deployment

Date

Location
Loch Craignish, Scotland

30 modular reefs in shell-based materials were deployed.

600 Flat European oyster spats glued to reefs, which will be monitored and measured to study the mortality and growth rates.

In June 2024, we installed 14 artificial clay reef tiles on Hundested harbour wall and 10 boulder clay reefs on the seabed at DHI’s testing facility in collaboration with Anemo Robotics and DTU Aqua. Using underwater cameras and AI species recognition, we can see the impact of our artificial reefs on marine biodiversity, which includes a 400% increase in fish abundance and a 200% increase in species.
