Ecobarrier Bubble Curtains

Tackle marine pollution caused by floating and subsurface debris.



The Ecobarrier Bubble Curtain is a submerged high pressure pipe that runs along the seabed. Compressed air is pumped through the Bubble Tubing®, designed by, which creates a wall of bubbles rising to the surface. The bubbles are permeable to water, however, act as a barrier to:

1) Control the movement of floating & subsurface debris, such as plastics;
2) Divert jellyfish and other marine life from intake pipes;
3) Attenuate shock wave impact from blasting or pile driving to protect marine life.

Ecobarrier Air Curtains

Ecobarrier Bubble Curtains are suitable for long-term use in marinas, ports, canals, intake structures and offshore environments.

Installation is easy, with low running costs and maintenance is kept to a minimum. Vessels can pass over the top of the barrier at any time, so marine traffic can flow freely. They can easily be removed and redeployed at a different location.
