Modular Sealife System

What is MOSES?

The Modular Sealife System (MOSES) is a modular building system. It can be installed in the ocean or in waterways, where after it serves as habitat for marine life to find food, shelter, and a safe space to reproduce. MOSES enables the construction of functional maritime structures, such as riverbank reinforcements, wave breakers or scour protection that simultaneously function as artificial reefs. The innovative ReefSystems ingredient mix enables the construction of structures with similar size and strength using 40% less concrete, resulting in decreased CO2-emissions.

Have the effects of MOSES been tested?

Wageningen University & Research has conducted a case study to research the effect of MOSES in the ecosystem of Haringvliet, the Netherlands and they saw an increase of several species! Want to learn more?

What species does MOSES attract?

Each module can be modified to create various microhabitats. Local species such as crabs, lobsters, mussels, oysters, and corals can find shelter within MOSES-reefs in different life cycle stages. The outside surface has a rough texture, which functions as hard substrate. We have noticed that  juvenile fish are exploring the different microhabitats immediately after installation.

Sheet Pile Eco-Territorial Reinforcement

What is SPECTER?

SPECTER is a multi-layered hanging case that can be installed onto sheet piles. Within the SPECTER cases native aquatic plants are placed. When these plants have grown they have a positive effect on the water quality and the surrounding ecosystem. When installed along canals, fish can find food, shelter and a safe space to reproduce along their migration route. With SPECTER it is possible to bring back nature in places, where this hasn't been possible before.

What species does SPECTER attract?

Above water the plants attract birds, bees and other insects. Additionally the vegetation creates a pleasant street view with a positive environmental impact.

Just below the water surface juvenile fish, such as the three-spined stickleback and elver have the option to find food and shelter within the SPECTER cases.

Under water the water plants create a green aquatic wall full of insect larvae, water snails and other aquatic invertebrates. These organisms are food for fish. 


What is a Reefpool?

Reefpools are structural performing armor units that can be used for dike reinforcements while promoting population growth of marine organisms. By mimicking natural rock pools, Reefpools function as intertidal habitats along dikes or wave breakers. Reefpools will fill up with fresh water and nutrients during high tide (2 times a day), which attracts all sorts of organisms. 80% of Reefpools consists out of natural materials. The additional 20% is bio-concrete (blast furnace cement), which is produced with half of the CO2-emissions of traditional concrete. The shells that are added in the Reefpools create a bioreceptive hard substrate for organisms to settle on. Additionally these shells contain a high amount of calcium carbonate, which is used by oysters and mussles to build their own shells.

What species does the Reefpool attract?

The Reefpool is designed to form a place of refuge for crustaceans, such as crabs, lobsters and shrimps. Some of these crustaceans will attract birds which feed on these animals. In addition, the bio-receptive surface will attract mollusks such as oysters and mussels and various types of seaweeds and algae can grow onto it. The 2021-2023 pilot project at the Lauwersmeerdijk in the Netherlands will give insights into what species will adopt the tidal pool as their habitat.
