Bubble curtains: A powerful solution, but don’t DIY
When correctly engineered and tailored to local site conditions, Bubble Curtains provide a highly effective solution for trapping sediment, reducing noise, aerating water, and preventing pollution from spreading downstream - a level of performance and reliability that DIY systems can’t match.
Micro bubble curtains study: impact on sediment dispersal
This study outlines findings of using Bubble Curtains for effective sediment control.
Mitigating underwater explosion effects with bubble curtains
Mitigation of shocks and noises is made possible by the use of a bubble curtain set around the explosive charge.
Developing an underwater shock suppression system to mitigate underwater blast effects on marine life
Research findings evaluating the performance of the bubble screens at Roach Cove, an underwater demolition training area.
Noise reduction by an air bubble curtain in offshore pile driving
In this paper, a model is proposed for the investigation of the sound reduction during marine piling when an air-bubble curtain is placed around the pile.
Protecting vessels from fouling using air bubble curtains
This paper describes novel technology to protect vessels whilst stationary using air bubble curtains.
Underwater sound mitigation of bubble curtains with different bubble sizes
Without mitigation measures, piling generates sound pressure levels which exceed the limit values for the sound exposure level and the peak level at distance 750 m. In this work, results from acoustical tests on bubble curtains as well as a first attempt for modeling the mitigation effect of bubble curtains are presented and discussed.
Noise reduction study - air bubble curtain in offshore piling
This paper describes a semi-analytical model that is used for the investigation of the sound reduction during marine piling when an air bubble curtain is placed around the pile.
Bubble Curtains attenuating noise pollution for harbour porpoises
This research shows bubble curtains dampen noise from offshore wind farm construction and reduce temporary habitat loss for harbour porpoises.
