Finite‑element modelling simulations demonstrate reduced underwater noise, with significant reductions in both sound exposure levels and sound pressure levels compared to conventional impact hammers.
As the next generation of ‘at the source’ noise mitigation, EQ-Piling leverages decades of experience with conventional impact hammers and near-field noise reduction techniques.
EQ‑Piling uses a large water tank filled with seawater as a drop weight. The tank is lifted by hydraulic cylinders and released from the drop height setpoint.
The water tank falls onto buffer cylinders which transmit the impact force onto the pile, dampening it to extend the impact time. This impact time is 15 -20 times longer than that of conventional impact piling, resulting in a smooth energy transfer to the monopile and significantly reduced noise levels.
