Bubble Curtains Validated Through Trials in Ireland

New results from Ireland’s 2024 Marine Challenge project confirm that large-scale bubble curtain systems can perform reliably in real offshore conditions, even in strong tides and heavy seas.

More than 2.4 kilometers of Bubble Tubing® was deployed across two commercial salmon farm sites, making this the largest installation ever tested in Ireland. The trials validated multiple different depth configurations, High Density Polyethylene (HDPE) air feeder lines, and weighted bubble curtain systems designed to maintain stable, even airflow across large farm perimeters.

The outcome: consistent air flow and a 60% reduction in harmful plankton levels inside protected areas.

For the aquaculture industry, this marks a major milestone, demonstrating that bubble curtain tubing is no longer experimental but now a proven at commercial scales.
