Simulations using finite element modelling show a significant reduction in sound exposure levels as well as sound pressure levels compared to conventional 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 utilizes a large water tank as a drop weight. This tank, containing up to seventeen hundred tons of seawater, is raised 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 piling, resulting in a smooth energy transfer to the monopile and significantly reduced noise levels.
