Underwater noise from vibratory pile driving with non-linear frictional pile–soil interaction

Vibratory offshore pile driving offers a potential solution for reducing the underwater noise generated during the installation of foundation piles compared to using impact hammers. Existing noise prediction models are specifically tailored to impact pile driving scenarios. This paper introduces a novel methodology for underwater noise...

Influence of the seabed conditions on the near-and far-field propagation of noise in impact piling

The prediction of underwater noise and the assessment of the influencing factors on noise transmission are significant for the control and mitigation of the noise generated by offshore pile driving. This paper presents a coupled two-step approach for modelling the underwater noise from offshore pile driving, with the focus being placed on...

Study of the sound escape with the use of an air bubble curtain in offshore pile driving

Underwater noise pollution generated by offshore pile driving has raised serious concerns over the ecological impact on marine life. To comply with the strict governmental regulations on the threshold levels of underwater noise, bubble curtains are usually applied in practice. This paper examines the effectiveness of an air bubble curtain...

A coupled modelling approach for the fast computation of underwater noise radiation from offshore pile driving

This paper presents a computationally efficient modelling approach for the prediction of underwater noise radiation from offshore pile driving. A near-source module is adopted to capture the interaction between the pile, fluid and soil, which is based on a previously developed semi-analytical vibro-acoustic model. This module primarily aims...

Underwater Noise Emission Due to Offshore Pile Installation: A Review

The growing demand for renewable energy supply stimulates a drastic increase in the deployment rate of offshore wind energy. Offshore wind power generators are usually supported by large foundation piles that are driven into the seabed with hydraulic impact hammers or vibratory devices. The pile installation process, which is key to the...
