CHARACTERISATION OF ACOUSTIC FIELDS GENERATED BY EXPLOSIVES - QUARRY TRIAL OF APPLICATION OF NOISE ABATEMENT TECHNOLOGY

Summary

Offshore wind farm and cable projects in the UK face the challenge of safely disposing of unexploded ordnance (UXO), which can cause significant acoustic noise harmful to marine life, with potential injury zones extending up to 15 km for large charges. This project conducted controlled experimental trials in a quarry facility to investigate the effectiveness of bubble curtains as a noise abatement technology for underwater explosive sources. The completed trials, involving 23 explosive tests over six days, demonstrated that bubble curtains can provide attenuation, with effectiveness influenced by charge size, distance from the charge, and bubble curtain parameters.
