Our obligation is to protect and improve our waters, and to prevent negative effects of human activities

WATER IS OUR LIFE
This is what we do
Bubble curtains Silt curtains Sediment treatment
The bubble curtiains prevent damage from explosions and pile driving, Silt curtains prevent particle spreading from worksites into waters
All installations and services are tested in real life, effects are controlled and documented. Silt curtains effects are monitored by automatic tubidity buoys, bubble curtains by noise detectors, sediment treatment by sample and flow analysis

This is how it works and looks

The bubble curtain let compressed air out into the water column through a number of small orifices. The great number of small bubbles created rises slowly to the surface. The sum of the surface area and volume of the air bubbles affects the water environment in a number of ways, and can help;
- reduce noise and pressure vawes
- transport bottom water to surface
- prevent ice
- stop silt and debree
The Waens bubble curtain construction makes it easy to transport, assemble and mount. Powerful installations can be mounted by small crafts, without the need for barges and cranes.
Human activity at shores and in waterways mix particles from land or seabed sediments. The particles may carry pollutants and will cloud the water. The silt curtain provide a physical barrier, letting water through, holding the particles back.
The right solution
We supply solutions for every challenge from the single curtain for a excavated pipe landing to complexe curtains in streaming waters, passable for ship traffic, curtains with oil stop, just ask!
Generations into the industrial era we have left an abundance of excess nutrients and toxic waste in our waters. Today this is sitting in the sediments, slowly leaking into the water bodies, causing algae bloomings and other ecological problems.
Stop the internal strain in water bodies
The leaks from the sediments make a severe internal strain on a lot of waters. Treatment of the seabed either by removing nutrients/pollutants or fixating them in the sediment is needed to improve ecological status within a reasonable timeframe. Waens know the solutions.
From our blog
Silt can carry pollutants, cloud waters an cover bottom life. How do you prevent or mitigate the problem? The video above from Western Washington University shows how silt-contaminated currents move rapidly throug water bodies. The video shows how widely silt pollution will affect the waters, and illustrate how important it is to manage this when…
The Norwegian research institute SINTEF has been doing reserarch indicating that hurricanes can be prevented by Bubble curtains bringing cold water from the deep up to the surface to cool the surface water. This will slow down or stop the formation and powering of hurricanes, that depent on at surface temperatur of at least 26,5…
