New project: Bubbles JIP
To achieve more efficient and effective use of bubble curtains for noise mitigation in offshore installation projects
In April 2020, GROW partners start the Bubbles JIP project. This Joint Industry Project researches the sound propagation of piling noise through water and soil and the physical mechanism of noise attenuation by air bubbles. The Dutch maritime institute MARIN leads the project and is supported by six GROW partners (Boskalis, Royal IHC, Seaway7, TNO, TU Delft and Van Oord) and by two visiting partners (Heerema and Wageningen Marine Research). The expected results of the project are:
- a computer model to calculate the effect of improved configurations of air bubble curtains.
- technology to measure the bubble size distribution and concentration over the water depth, also in relation to waves and current.
GROW expects to complete the project in the spring of 2022.
